Pneumocephalus associated with ethmoidal sinus osteoma--case report. (1/308)

A 35-year-old female suffered sudden onset of severe headache upon blowing her nose. No rhinorrhea or signs of meningeal irritation were noted. Computed tomography (CT) with bone windows clearly delineated a bony mass in the right ethmoid sinus, extending into the orbit and intracranially. Conventional CT demonstrated multiple air bubbles in the cisterns and around the mass in the right frontal skull base, suggesting that the mass was associated with entry of the air bubbles into the cranial cavity. T1- and T2-weighted magnetic resonance (MR) imaging showed a low-signal lesion that appeared to be an osteoma but did not show any air bubbles. Through a wide bilateral frontal craniotomy, the cauliflower-like osteoma was found to be protruding intracranially through the skull base and the overlying dura mater. The osteoma was removed, and the dural defect was covered with a fascia graft. Histological examination confirmed that the lesion was an osteoma. The operative procedure resolved the problem of air entry. CT is superior to MR imaging for diagnosing pneumocephalus, by providing a better assessment of bony destruction and better detection of small amounts of intracranial air.  (+info)

CT and MR findings of Michel anomaly: inner ear aplasia. (2/308)

In 1863, Michel described a condition characterized by a total absence of differentiated inner ear structures associated with other skull base anomalies, including an abnormal course of the facial nerve and jugular veins. Michel aplasia clearly differs from Michel dysplasia, in which arrest of embryologic development occurs later. Recently, the role of otic capsule formation on mesenchymal differentiation was reported as well as the impact of the genetic deletion of the homeobox gene on the development of the ear, cranial nerves, and hindbrain. We report two patients with a total absence of inner ear structures bilaterally, illustrating the characteristic appearance of Michel aplasia and associated skull base anomalies.  (+info)

Comparison of cervicovertebral dimensions in Australian Aborigines and Caucasians. (3/308)

Cervicovertebral dimensions were compared in a group of 30 male and 30 female young adult Australian Aborigines from the Northern Territory, and a control sample consisting of 60 Caucasian dental students from Adelaide, matched for sex and age. Thirty-six variables, 22 cervical and 14 craniofacial, were derived from standardized lateral roentgenograms with the use of a computerized cephalometric system. Vertebral body height and length were significantly greater in Aboriginal males than females for C3 to C7, while dorsal arch height of C1 and C2 displayed the greatest dimensional variability in both sexes. The antero-posterior length of C1, dens height, and body heights of C3 and C4 were significantly shorter in Aborigines than Caucasians for both males and females. Total length of the column from C2 to C6 was approximately 12 per cent shorter in the Aborigines compared with Caucasians. The height of the posterior arch of C1 was significantly correlated with one or both posterior cranial base lengths in Aborigines and Caucasians. Associations were also noted between mandibular lengths and posterior arch heights of the upper two vertebrae. The results confirm and clarify several previous observations on the relative shortness of the cervical spine in Australian Aboriginals. They also indicate some associations between dimensions of the cervical vertebrae and craniofacial lengths, particularly those representing the posterior cranial base and the mandible.  (+info)

Effect of low-dose testosterone treatment on craniofacial growth in boys with delayed puberty. (4/308)

Craniofacial growth was investigated in boys treated with low-dose testosterone for delayed puberty (> 14 years old; testicular volume < 4 ml; n = 7) and compared with controls (12-14 years; n = 37). Cephalometric radiographs, statural height and pubertal stage were recorded at the start of the study and after 1 year. Craniofacial growth was assessed by nine linear measurements. At the beginning of the study, statural height, mandibular ramus length, upper anterior face height, and total cranial base length were significantly shorter in the delayed puberty boys than in the controls. After 1 year, the growth rate of the statural height, total mandibular length, ramus length, and upper and total anterior face height was significantly higher in the treated boys than in the untreated height-matched controls (n = 7). The craniofacial measurements were similar in the treated boys as compared with the controls. These results show that statural height and craniofacial dimensions are low in boys with delayed puberty. Low doses of testosterone accelerate statural and craniofacial growth, particularly in the delayed components, thus leading towards a normalization of facial dimensions.  (+info)

Angiographically occult dural arteriovenous malformation in the anterior cranial fossa--case report. (5/308)

A 62-year-old male presented with a dural arteriovenous malformation located in anterior cranial fossa manifesting as acute right frontal intracerebral and subdural hematomas. Cerebral angiography showed only mass sign, but surgical exploration disclosed the dural arteriovenous malformation in the anterior cranial fossa. Anterior cranial fossa dural arteriovenous malformation should be considered if computed tomography reveals intracranial bleeding involving the frontal base, even if cerebral angiography does not demonstrate vascular anomalies.  (+info)

Craniofacial morphology in 6-year-old Icelandic children. (6/308)

The purpose of the study was to describe the craniofacial characteristics of 6-year-old Icelandic children, make a normative standard for children with an Angle Class I molar relationship, and compare them to those with an Angle Class II molar relationship. The material consisted of the radiographs of 363 children, 184 (50.7 per cent) boys and 179 (49.3 per cent) girls with a mean age of 6 years 7 months (range: 5 years 7 months-7 years 8 months). Twenty-two reference points were digitized and processed by standard methods with the Dentofacial Planner computer software program. The 33 variables calculated included both angular and linear. Two sample t-tests were used to study the differences between different groups. Only minimal differences could be noted between sexes in sagittal and vertical angular measurements. Linear measurements, on the other hand, were usually larger for the boys. When compared with Norwegian material of the same age group, similar trends were observed between sexes in both studies, but the Icelandic children showed slightly more mandibular prognathism and a lower mandibular plane angle. When compared with children with an Angle Class I molar relationship, children with an Angle Class II molar relationship did not have a different maxillary prognathism nor a different mandibular length. Cranial base dimensions were all significantly greater and the cranial base flexure was also significantly more obtuse in the distal group.  (+info)

Differential responses to parathyroid hormone-related protein (PTHrP) deficiency in the various craniofacial cartilages. (7/308)

PTHrP null mutant mice exhibit skeletal abnormalities both in the craniofacial region and limbs. In the growth plate cartilage of the null mutant, a diminished number of proliferating chondrocytes and accelerated chondrocytic differentiation are observed. In order to examine the effect of PTHrP deficiency on the craniofacial morphology and highlight the differential feature of the composing cartilages, we examined the various cartilages in the craniofacial region of neonatal PTHrP deficient mice. The major part of the cartilaginous anterior cranial base appeared to be normal in the homozygous PTHrP deficient mice. However, acceleration of chondrocytic differentiation and endochondral bone formation was observed in the posterior part of the anterior cranial base and in the cranial base synchondroses. Ectopic bone formation was observed in the soft tissue-running mid-portion of the Meckel's cartilage, where the cartilage degenerates and converts to ligament in the course of normal development. The zonal structure of the mandibular condylar cartilage was scarcely affected, but the whole condyle was reduced in size. These results suggest the effect of PTHrP deficiency varies widely between the craniofacial cartilages, according to the differential features of each cartilage.  (+info)

The mouse bagpipe gene controls development of axial skeleton, skull, and spleen. (8/308)

The mouse Bapx1 gene is homologous to the Drosophila homeobox containing bagpipe (bap) gene. A shared characteristic of the genes in these two organisms is expression in gut mesoderm. In Drosophila, bap functions to specify the formation of the musculature of the midgut. To determine the function of the mammalian cognate, we targeted a mutation into the Bapx1 locus. Bapx1, similar to Drosophila, does have a conspicuous role in gut mesoderm; however, this appears to be restricted to development of the spleen. In addition, Bapx1 has a major role in the development of the axial skeleton. Loss of Bapx1 affects the distribution of sclerotomal cells, markedly reducing the number that appear ventromedially around the notochord. Subsequently, the structures in the midaxial region, the intervertebral discs, and centra of the vertebral bodies, fail to form. Abnormalities are also found in those bones of the basal skull (basioccipital and basisphenoid bones) associated with the notochord. We postulate that Bapx1 confers the capacity of cells to interact with the notochord, effecting inductive interactions essential for development of the vertebral column and chondrocranium.  (+info)

Endoscopic skull base surgery has created a new era of skull base surgery. With the development of endoscopic skull base surgery technology and the cooperation in-depth among multiple disciplines, endoscopic skull base surgery has gradually expanded from midline skull base to paramidline skull base. In addition to pituitary tumor, meningioma, craniopharyngioma, and other benign lesions, the technology of endoscopic skull base surgery is gradually used in the treatment of malignant lesions, with olfactory neuroblastoma being the most typical. In addition, endoscopic skull base surgery in the treatment of recurrent nasopharyngeal carcinoma, adenoid cystic carcinoma, chordoma, and other malignant lesions also showed obvious advantages. The combination of interventional neuroradiology, surgical revascularization technique, and endoscopic skull base surgical technique further expands the indications of endoscopic skull base surgery, and greatly reduced the risk of internal carotid artery injury.

Background. Nasal lavage with mupirocin has the potential to reduce sinonasal morbidity in endoscopic endonasal approaches for skull base surgery. Objective. To evaluate the effects of nasal lavage with and without mupirocin after endoscopic endonasal skull base surgery. Methods. A pilot randomised, controlled trial was conducted on 20 adult patients who had undergone endoscopic endonasal approaches for skull base lesions. These patients were randomly assigned to cohorts using nasal lavages with mupirocin or without mupirocin. Patients were assessed in the out-patient clinic, one week and one month after surgery, using the 22- item Sino-Nasal Outcome Test questionnaire and nasal endoscopy. Results. Patients in the mupirocin nasal lavage group had lower nasal endoscopy scores postoperatively, and a statistically significant larger difference in nasal endoscopy scores at one month compared to one week. The mupirocin nasal lavage group also showed better SinoNasal Outcome Test scores at one month ...

Y1 - 1988/11. N2 - In 1981, the senior author first reported the use of the pericranial flap for support of the brain following resection of the anterior skull base. Since the initial report, considerable experience has been gained with this flap. It is currently deployed via a bifrontal craniotomy and is placed primarily as a support beneath the frontal lobes. The pericranial flap may also be used to repair dural laceration and defects. The sinonasal surface is routinely grafted with split-thickness skin or dermis. This technique provides an excellent barrier between the sinonasal cavity and the cerebrospinal fluid, establishing a tough, fibrous platform. Herniation of intracranial contents has not occurred. One major complication has been reported in which radiation necrosis occurred during postoperative ...

Xie et al. constructed an easy model using silicone and acrylic as sphenoid sinus and using the egg-shell membrane as skull base dura. The training is divided into three steps: Step 1: extracorporeal knot-tying suture on the silicone of sphenoid sinus, Step 2: intra-nasal knot-tying suture on the same silicone, and Step 3: intra-nasal egg-shell membrane knot-tying suture. Fifteen experienced microneurosurgical neurosurgeons (Group A) and ten inexperienced PGY residents (Group B) were recruited to perform the tasks. Performance measures were time, suturing and knotting errors, and needle and thread manipulations. The third step was ...
Free tissue transfer has been the gold standard of extensive skull base reconstruction, but the onlay of free flaps onto skull base defects carries the risk of cerebrospinal fluid (CSF) leakage. The purpose of this study was the evaluation of a novel technique of a combined sub- and onlay concept with a partially intracranially positioned folded free fasciocutaneous flap in terms of flap applicability, versatility and complication rate. Within 5 years, 7 patients with anterior (n=4), middle (n=2) or posterior (n=1) skull base defects were reconstructed with free extended lateral arm (n=3) or anterolateral thigh (n=4) flaps. The flaps were partially intracranially positioned and fixed with osteo-dermal sutures. Both flaps proved to be applicable in terms of sealing efficiency, minimizing intracranial flap volume and folding. No flap loss was observed. Specific complications consisted of one pneumocranium via an accessory frontal sinus and one cerebellar herniation due to lumbar CSF loss. No flap ...
TY - JOUR. T1 - Diagnosis of skull base lesions. T2 - The role of CT guided biopsy. AU - Manzione, James V.. AU - Shindo, Maisie L.. PY - 1998/12/1. Y1 - 1998/12/1. N2 - Accurate histologie diagnosis is important for treatment planning of skull base lesions. However, obtaining tissue diagnosis of lesions in or around the skull base can be difficult. Extensive surgery is often required for tissue biopsy with the potential for debilitating complications. This paper describes the usefulness of CT guided biopsy of lesions located at various sites in the skull base for establishing histologie diagnosis. CT guided biopsies of lesions in and around the skull base (pterygopalatine region, greater wing of the sphenoid, parapharyngeal space, infratemporal fossa) were performed in 5 patients who otherwise would have required complicated open surgical approaches. Biopsies were obtained using 18 to 22 gauge needles via one of two approaches - through the coronoid notch or transorally. Accurate diagnosis ...

Current standard of care for complex head, neck and skull base surgery require navigation systems that allow instruments to be tracked optically or electromagnetically while registered to a patients pre-operative X-ray computed tomography (CT) or magnetic resonance image (MRI). However, conventionally, the CT/MRI data is not registered with video endoscopy. Augmentation of endoscopic video by preoperative data can facilitate navigation around critical structures and robust target resection. The work presented here describes evaluation of a high definition (HD) video-overlay system for endonasal endoscopic skull base surgery. We adopt a modular design that can be extended for other video augmentation applications. The system supports fast automatic camera calibration, comparable in re-projection errors to standard camera calibration tools, while performing within appropriate run time for clinical use. Phantom studies have shown the registration accuracy of the system to be equivalent to that of ...

BACKGROUND: Nonvestibular schwannomas of the skull base often represent a challenge owing to their anatomic location. With improved techniques in endoscopic endonasal skull base surgery, resection of various ventral skull base tumors, including schwannomas, has become possible.. OBJECTIVE: To assess the outcomes of using endoscopic endonasal approach (EEA) for nonvestibular schwannomas of the skull base.. METHODS: Seventeen patients operated on for skull base schwannomas by EEA at the University of Pittsburgh Medical Center from 2003 to 2009 were reviewed.. RESULTS: Three patients underwent combined approaches with retromastoid craniectomy (n = 2) and orbitopterional craniotomy (n = 1). Three patients underwent multistage EEA. The rest received a single EEA operation. Data on degree of resection were found for 15 patients. Gross total resection (n = 9) and near-total (,90%) resection (n = 3) were achieved in 12 patients (80%). There were no tumor recurrences or postoperative cerebrospinal fluid ...

Ameloblastic fibrosarcoma is a malignant odontogenic tumor that rarely affects the skull base and surrounding regions. We present a case of a 48-year-old man with histologically confirmed malignant transformation of a benign ameloblastic fibroma 10 years after initial presentation of a localized facial mass. The ameloblastic fibrosarcoma extended from the facial region to the orbit, anterior and middle fossa skull base, the infratemporal fossa, and the cavernous sinus. Progressive proptosis with complete monocular vision loss was the presenting symptom. To our review, our case represents the first report of intradural extension of ameloblastic fibrosarcoma. Using a multidisciplinary skull base approach, resection of all tumors except that in the cavernous sinus was achieved with the resulting defect reconstructed with an anterolateral thigh free flap. The patient had no new neurologic deficits after surgery and underwent adjuvant fractionated radiation therapy. Malignant transformation of ...

I was really looking forward to getting my hands on this textbook. I am always left ever so slightly stunned by Aldo Stamms lectures; they feel a little like a rollercoaster journey, where one is taken on a thrilling ride through the endoscopic anatomy of the skull base, with arteries and cranial nerves flying past at every turn. As a lecturer, Aldo is hard to beat in terms of both charm and dynamism, but sometimes I am left feeling a little inadequate as I cant quite keep up. I was therefore quite looking forward to the opportunity to stroll through at a slightly gentler pace, with the option to turn back the page and re-read a section, in the way you could never quite do in a lecture. Excuse me, could you just run through those last three slides again doesnt really work out so well.. In many respects, the book lived up to expectations - the quality of the images throughout is very good, and those from the Rhoton collection, in particular, are spectacular.

TY - JOUR. T1 - Skull base growth in craniosynostosis. AU - Goodrich, James Tait. PY - 2005/10/1. Y1 - 2005/10/1. N2 - Introduction: The interrelationship of skull base growth and craniosynostosis is one that is not often taken into account in the clinical management of patients with craniofacial disorders by neurosurgeons and craniofacial surgeons. Very early on in our medical training we are taught the anatomical differences between the calvarial unit and skull base portion of the skull. The inherent differences in both underlying tissue components and the different growth characteristics of these two uniquely different structures are critical in understanding skull base growth in craniosynostosis and the inherent potential craniofacial growth in these unique children. Review: This paper will review some of the basic anatomy of these zones of growth plus review some of the prevalent theories of the effect of skull base growth on craniosynostosis and the converse. Conclusion: While the theories ...

AU - Anand, Vijay K.. AU - Schwartz, Theodore H.. PY - 2011/12/1. Y1 - 2011/12/1. N2 - The surgical approach to the skull base has traditionally been transcranial, often involving extensive bone drilling, brain retraction, and nerve manipulation to expose pathology. The endoscopic endonasal approach represents a minimal access, maximally aggressive alternative that provides a direct route to the area of interest. Few data exist that can be used to compare these 2 surgical strategies. We conducted a systematic review of case series and case reports in hope of furthering our understanding of the role of endoscopy in the management of difficult cranial base lesions. We found that the endonasal endoscopic technique generates equivalent or greater rates of gross total resection than open approaches for craniopharyngiomas, ...

Giant cell tumours (GCT) of the skull base account for approximately 1% of all GTC of the bone. Despite being considered as a benign neoplasm, they are locally aggressive with high recurrence rates after incomplete surgery. Due to the small number of cases reported in skull base, standardized treatment remains unclear. Even with new surgical techniques, a complete resection in skull base tumours is not always possible without functional compromise. Therefore, adjuvant therapy is essential to enhance local control and quality of life. We described a case treated successfully with primary surgery followed by Cyberknife stereotactic radiosurgery (SRS) and denosumab with a 48-month follow-up. To the best of our knowledge, the usage of combined therapy, SRS and denosumab, in skull base GCT has not been previously described.

Abstract BACKGROUND: We study the occurrence and management of the trigeminocardiac reflex (TCR) during neurosurgical procedures for lesions of the skull base. METHOD: Two hundred patients underwent neurosurgical procedures for various skull base lesions and were evaluated retrospectively for the occurrence of the TCR during surgery. This phenomenon was defined as the onset of bradycardia lower than 60 beats/minute and hypotension with a drop in mean arterial blood pressure of 20% or more due to intra-operative manipulation or traction on the trigeminal nerve. FINDINGS: Sixteen patients (8%) had a TCR intra-operatively (7 vestibular schwannomas, 5 sphenoid wing meningiomas, 3 petroclival meningiomas, 1 intracavernous epidermoid cyst). In all 16 patients with a TCR the postoperative courses presented no complications that could be directly related to this intra-operative phenomenon.

N2 - The pedicled nasoseptal flap has become an indispensible tool for the reconstruction of skull base defects. This flap is easily harvested, provides a large surface area of vascularized tissue, and has few reported complications. We describe the case of a 60-year-old man who underwent endoscopic, endonasal transsphenoidal surgery with septal flap reconstruction who developed a sphenoid sinus mucocele postoperatively. We also have reviewed the literature for similar findings and discuss this complication in the setting of pituitary surgery and endoscopic skull base repair. Although likely a rare occurrence, mucocele formation after septal flap reconstruction should be recognized and monitored with postoperative nasal endoscopy and radiologic imaging. Reoperation or mucocele drainage may be necessary if symptomatic ...
Endonasal procedures may be necessary during management of craniofacial trauma. When a skull base fracture is present, these procedures carry a high risk of violating the cranial vault and causing brain injury or central nervous system infection. A 52-year-old bicyclist was hit by an automobile at high speed. He sustained extensive maxillofacial fractures, including frontal and sphenoid sinus fractures (Fig. 1). He presented to the emergency room with brisk nasopharyngeal hemorrhage, and was intubated for airway protection. He underwent emergent stabilization of his nasal epistaxis by placement of a Foley catheter in his left nare and tamponade with the Foley balloon. A six-vessel angiogram showed no evidence of arterial dissection or laceration. Imaging revealed inadvertent insertion of the Foley catheter and deployment of the balloon in the frontal lobe (Fig. 2). The balloon was subsequently deflated and the Foley catheter removed. The patient underwent bifrontal craniotomy for dural repair of ...
Healthcare services in many countries have been partially or completely disrupted by the Coronavirus (COVID-19) pandemic since its onset in the end of 2019. Amongst the most impacted are the elective medical and surgical services in order to conserve resources to care for COVID-19 patients. As the number of infected patients decrease across Canada, elective surgeries are being restarted in a staged manner. Since Otolaryngologists - Head & Neck Surgeons manage surgical diseases of the upper aerodigestive tract where the highest viral load reside, it is imperative that these surgeries resume in a safe manner. The aim of this document is to compile the current best evidence available and provide expert consensus on the safe restart of rhinologic and skull base surgeries while discussing the pre-operative, intra-operative, and post-operative care and tips. Risk assessment, patient selection, case triage, and pre-operative COVID-19 testing will be analyzed and discussed. These guidelines will also consider

Skull base is a term used to refer to the region of the head that lies beneath the brain and at the base of the skull. Conditions most commonly addressed at the skull base include tumors and abnormalities of the blood vessels leading to the brain. These abnormalities are often highly complex to manage because of the complicated anatomy at the base of the skull. Tumors and vascular abnormalities in this area often require a team approach, using the expertise of physicians from multiple specialties.. ...

Palliative RT has been the standard treatment for skull base malignancies providing excellent relief of pain and improvement of cranial nerve dysfunction in up to 78% of patients [4-9]. More recently, SRS has been employed as a less invasive option for the treatment of skull base metastases with the aim to deliver a high dose to the target with dose sparing of critical structures such as the optic nerves and chiasm. The efficacy of single-fraction SRS for skull base metastases has been reported in few studies that include either nasopharyngeal carcinomas or skull base metastases [14-17]. Iwai et al. [15] treated 21 patients with cavernous sinus cancers, including 12 patients with metastases from systemic cancer. At a median follow-up of 13 months, the 1-year and 2-year tumor control rates were 68% and 47%, respectively, with no significant differences between nasopharyngeal carcinoma and metastases. After SRS, there was a resolution or improvement of preoperative cranial nerve deficits in 47% of ...

Endoscopic endonasal surgery is a minimally invasive technique used mainly in neurosurgery and otolaryngology. A neurosurgeon or an otolaryngologist, using an endoscope that is entered through the nose, fixes or removes brain defects or tumors in the anterior skull base. Normally an otolaryngologist performs the initial stage of surgery through the nasal cavity and sphenoid bone; a neurosurgeon performs the rest of the surgery involving drilling into any cavities containing a neural organ such as the pituitary gland. Antonin Jean Desomeaux, a urologist from Paris, was the first person to use the term, endoscope. However, the precursor to the modern endoscope was first invented in the 1800s when a physician in Frankfurt, Germany by the name of Philipp Bozzini, developed a tool to see the inner workings of the body. Bozzini called his invention a Light Conductor, or Lichtleiter in German, and later wrote about his experiments on live patients with this device that consisted of an eyepiece and a ...
