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 ...
TY - JOUR. T1 - The pericranial flap for reconstruction of anterior skull base defects. AU - Price, John C.. AU - Loury, Mark. AU - Carson, Benjamin. AU - Johns, Michael E.. PY - 1988/11. 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 ...

Cerebrospinal fluid leakage is always the primary complication during the endoscopic endonasal skull base surgery.. Dural suturing technique may supply a rescue method. However, suturing and knotting in such a deep and narrow space are difficult. Training in the model can improve skills and setting a stepwise curriculum can increase trainers interest and confidence.. 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 ...

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 ...

Methods. Between 1992 and 2002, 41 patients (28 male and 13 female patients with a mean age of 38.3 ...
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. The anatomy is described first, ...
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, ...

The importance of quality of life (QOL) outcomes following treatments for head and neck tumors are now increasingly appreciated and measured to improve medical and surgical care for these patients. An understanding of the definitions in the setting of health care and the use of appropriate QOL instruments and measures are critical to obtain meaningful information that guides decision making in various aspects of patient health care. QOL outcomes following cranial base surgery is only recently being defined. In this article, we describe the current published data on QOL outcomes following cranial base surgery and provide preliminary prospective data on QOL outcomes and sinonasal morbidity in patients who underwent endonasal cranial base surgery for management of various skull base tumors at our institution. We used a disease-specific multidimensional instrument to measure QOL outcomes in these patients. Our results show that although sinonasal morbidity is increased, this is temporary, and the ...

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.

Resident duty-hours restrictions have now been instituted in many countries worldwide. Shortened training times and increased public scrutiny of surgical competency have led to a move away from the traditional apprenticeship model of training. The development of educational models for brain anatomy is a fascinating innovation allowing neurosurgeons to train without the need to practice on real patients and it may be a solution to achieve competency within a shortened training period. The authors describe the use of Stratathane resin ST-504 polymer (SRSP), which is inserted at different intracranial locations to closely mimic meningiomas and other pathological entities of the skull ...

Drs. Chandler and Silva do agood job describing the bifrontalbiorbital sphenoethmoidalapproach to the skull base.This approach allows full access tothe anterior skull base, the paranasalsinuses between the medial thirds ofthe maxillary sinuses, and the entireclivus medial to the carotid arteriesand the hypoglossal nerves and belowthe pituitary gland. It should berecognized that the full extent of theapproach is not always necessary, anda good degree of tailoring is possible.Specifically, I have not found it necessaryto perform orbital osteotomiesfor access to the paranasal sinuses orfor cribriform plate resection. A smallmidline frontal craniotomy with aninferior extension to the level of thefrontonasal suture is usually sufficient.
Background: The supraorbital keyhole approach has been used in anterior skull base tumor and aneurysm surgery. However, there are debates regarding the safety and limitations of this kind of approach. Objective: To determine the feasibility and potential benefits of surgical robotic technology in minimally invasive neurosurgery. Methods: Two fresh cadaver heads were studied with the…

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. CONCLUSIONS: Due to the intracranial course of the trigeminal nerve several surgical procedures at the anterior, middle
TY - JOUR. T1 - Mucocele formation under pedicled nasoseptal flap. AU - Vaezeafshar, Reza. AU - Hwang, Peter H.. AU - Harsh, Griffith. AU - Turner, Justin H.. PY - 2012. Y1 - 2012. 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 ...
