The supraorbital keyhole approach with eyebrow incisions for treating lesions in the anterior fossa and sellar region. (1/28)

BACKGROUND: Keyhole surgery has developed since the 1990s as a less invasive therapeutic strategy for intracranial lesions, initially for the treatment of intracranial aneurysms. The purpose of this study was to describe and evaluate the results of surgical treatment of lesions in the anterior fossa and sellar region via a supraorbital keyhole approach using eyebrow incisions. METHODS: Between April 1994 and July 2003, 54 patients with lesions in the anterior fossa and sellar region were operated on via the supraorbital keyhole approach. The surgical results were studied retrospectively and compared with that of patients with lesions at the same locations but treated via a conventional subfrontal approach. RESULTS: No significant difference in curative effect was found between the conventional subfrontal approach and the supraorbital keyhole approach. However, the supraorbital approach required a much smaller skin incision, causing less surgical trauma, while achieving excellent surgical exposure and good recovery. CONCLUSION: The supraorbital keyhole approach using an eyebrow incision is safe, effective, and both suitable and convenient for treating lesions in the anterior fossa and sellar region, with almost no adverse consequences on the facial features of patients.  (+info)

Detection of enlarged cortical vein by magnetic resonance imaging contributes to early diagnosis and better outcome for patients with anterior cranial fossa dural arteriovenous fistula. (2/28)

Twelve patients (10 men, 2 women) with anterior cranial fossa dural arteriovenous fistula (AVF) were treated at our institute between January 1976 and March 2002. Intracranial hemorrhage was the presenting symptom in six patients. Magnetic resonance (MR) imaging findings identified abnormal cortical veins as flow voids in four of five patients. Angiography was the basis of the diagnosis in all patients. Surgery was the primary treatment in nine patients. The other three patients refused intervention and managed conservatively. Surgical morbidity was negligible and the treatment outcome was highly dependent on the clinical status at presentation. In contrast to the reported high incidence of intracranial hemorrhage in patients with dural AVF in the anterior cranial fossa, only half of our study population presented with hemorrhage. Enlarged cortical veins in the frontobasal area could be detected as flow voids on MR images. This finding contributed to the early diagnosis and treatment of patients treated at our institution for dural AVF in the anterior cranial fossa, and to the better outcomes we obtained in these patients.  (+info)

Craniofacial resection for cranial base malignancies involving the infratemporal fossa. (3/28)

OBJECTIVE: Cranial base malignancies involving the infratemporal fossa have been considered unresectable. Advanced operative techniques have made tumor resection feasible in an en bloc fashion with negative histological margins, but there are limited data regarding outcome analysis in patients who have undergone resection of malignant tumors in this area. METHODS: At Memorial Sloan-Kettering Cancer Center, 25 patients underwent anterolateral cranial base resections for tumors that involved the infratemporal fossa during a 7-year period. The most common tumors were sarcoma (n = 9), squamous cell carcinoma (n = 6), and adenoid cystic carcinoma (n = 3). The median size of the tumors was 6 cm, and 12 tumors involved the anterior cranial base and/or orbit. Tumor resections were divided into three types. Twelve patients underwent Type 1 dissection for tumors involving only the infratemporal fossa and maxillary sinus; 2 patients underwent Type 2 dissections involving the infratemporal fossa and anterior cranial base; and 11 patients underwent Type 3 dissection, which included the infratemporal fossa, anterior cranial base, and orbit. All patients required free flap reconstruction, 22 of which were rectus abdominis free flaps. RESULTS: Complications occurred in seven patients, including a single mortality resulting from a myocardial infarction. The 2-, 3-, and 5-year survival rates were 69, 63, and 56%, respectively. The relapse-free survival rates were 47% at 2 and 3 years and 41% at 5 years. Recurrences were local in nine patients and distant in four patients. CONCLUSION: Despite the extensive nature of many infratemporal fossa tumors, they can be resected with acceptable morbidity. Survival rates approach those of anterior cranial base malignancies without infratemporal fossa involvement.  (+info)

Anterior ethmoidal artery aneurysm and intracerebral hemorrhage. (4/28)

The association between the formation of intracranial aneurysms and situations of increased blood flow in certain areas of the brain is well accepted today. It has been seen in association with arteriovenous malformations of the brain, carotid occlusion, and Moyamoya disease. The occurrence of aneurysms in small arteries of the skull base, with the exception of the intracavernous carotid artery, however, is rare. We report a case of a 55-year-old woman who presented with an intracerebral hemorrhage caused by a ruptured anterior ethmoidal artery aneurysm. To the best of our knowledge, this is only the second case of documented intracranial bleeding from such a lesion.  (+info)

Venous aneurysm development associated with a dural arteriovenous fistula of the anterior cranial fossa with devastating hemorrhage--case report. (5/28)

A 67-year-old man presented with devastating intracranial hemorrhage (ICH) from an anterior cranial fossa dural arteriovenous fistula (DAVF). Four years earlier, digital subtraction angiography had disclosed a DAVF at the right anterior cranial fossa fed mainly by the ethmoidal branches of the bilateral sphenopalatine arteries and slightly by the ethmoidal arteries of the bilateral ophthalmic arteries, and drained primarily by the sphenoparietal and cavernous sinuses via two dilated cortical veins and slightly by the superior sagittal sinus via a frontal ascending vein. Three-dimensional computed tomography angiography revealed the development of a venous aneurysm on the main draining vein over a 4-year period, but no other changes. Venous aneurysm development may be part of the natural history of DAVF with cortical venous drainage and may contribute to the occurrence of ICH.  (+info)

Usefulness of T2*-weighted MR sequence for the diagnosis of subfrontal schwannoma. (6/28)

Subfrontal schwannomas are rare tumors that are usually diagnosed during surgery. They are often misdiagnosed as meningioma or esthesioneuroblastoma because of their similar clinical and radiological features. We report a case of schwannoma arising from the floor of the anterior cranial fossa that had radiological features similar to that of meningioma. However, T2*-weighted MR imaging revealed multiple foci of low signal intensities within the tumor related to microbleeds, which suggested a diagnosis of schwannoma that was confirmed by histopathology. This case report demonstrates the usefulness of T2*-weighted sequence in distinguishing meningioma from schwannoma, especially in cases where the tumor has an unusual location.  (+info)

Osteoma of anterior cranial fossa complicated by intracranial mucocele with emphasis on its radiological diagnosis. (7/28)

We present a 43-year-old female patient who had recurrent headache for one year. An intracranial bony lesion surrounded by a cyst in the anterior cranial fossa was found on imaging. Postoperative histological examination confirmed the diagnosis of osteoma and mucocele.  (+info)

Intracranial aspergilloma in immunocompetent patients successfully treated with radical surgical intervention and antifungal therapy: case series. (8/28)

INTRODUCTION: Aspergillosis of the central nervous system is an uncommon infection, mainly occurring in immunocompromised patients with a high mortality. Surgical excision of the intracranial lesion combined with oral voriconazole has been proposed to improve the outcome in immunocompromised patients. Itraconazole has been considered not to be effective because of poor penetration into the brain tissue. We report the long-term outcome of 3 cases of intracranial aspergilloma in immunocompetent patients who were successfully treated with radical surgery combined with oral itraconazole. MATERIALS AND METHODS: This is a retrospective study in which chronic invasive intracranial aspergilloma was successfully treated in 3 apparently immunocompetent patients and followed-up for more than 5 years. RESULTS: Near complete or radical surgical removal of this localised chronic invasive intracranial aspergilloma whenever possible is the definitive treatment. When combined with the oral antifungal drug itraconazole, the management regimen is effective in achieving near complete long-term cure of more than 5 years. Oral itraconazole 200 mg twice daily should be given for a prolonged period of at least 6 months. CONCLUSION: In chronic invasive intracranial aspergilloma in an immunocompetent patient, it was suggested that radical excision of the intracranial aspergilloma combined with oral antifungal drug belonging to triazole group that can be either itraconazole or voriconazole given for a period of 6 months was likely to improve the long-term outcome.  (+info)

The posterior ethmoidal artery is an artery of the head which supplies the nasal septum. It is smaller than the anterior ethmoidal artery. Once branching from the ophthalmic artery, it passes between the upper border of the medial rectus muscle and superior oblique muscle to enter the posterior ethmoidal canal. It exits into the nasal cavity to supply posterior ethmoidal cells and nasal septum; here it anastomoses with the sphenopalatine artery. There is often a meningeal branch to the dura mater while it is still contained within the cranium. This artery supplies the posterior ethmoidal air sinuses, dura mater of the anterior cranial fossa, and the upper part of the nasal mucosa of the nasal septum.

The instructor will insert fingers between the frontal lobe and the floor of the anterior cranial fossa to gently raise the frontal lobe to display the olfactory bulb as it lies on the cribriform plate (842/N9). If possible, identify the olfactory tract extending posteriorly from the bulb to the inferior surface of the hemisphere. The bulbs can be teased away from the cribiform plate so that bulbs and tracts remain with the brain. Additional elevation of the two frontal lobes will display the optic nerves and chiasm (N101) in the midline about 2 ½ inches posterior to the crista galli. With a small pair of scissors the optic nerves are cut leaving the optic chiasm on the brain. (It is best to sever all cranial nerves with a scissors; pressure on them even with a sharp scalpel is likely to tear them from the brain). Immediately posterior to each optic nerve are the internal carotid arteries (893/N132). In the midline the very slender infundibulum (N100) (stalk of the hypophysis) is seen passing ...
Planum sphenoidale and tuberculum sella meningiomas arise from the floor of the anterior cranial fossa near the midline and present with visual disturbances due to compromise of the optic nerves and chiasm necessitating surgical removal in most cases. The traditional craniotomy and open surgical removal with decompression of the optic apparatus has been effectively used for many years.. A minimally invasive cranial approach via a supraorbital incision and bone opening is also reportedly used quite effectively to remove these tumors. Another option is the endoscopic endonasal approach (EEA) that has been increasingly used for this purpose over the past decade, and in experienced hands, has proven to be a safe and effective option as well. To date, the literature is limited primarily to small single institution, retrospective studies and meta-analyses comparing outcomes between the EEA and transcranial approaches. Here are a few seminal reviews.. In 2012, Komotar et al., published a meta-analysis ...
Andrei Makovik was a software designer and computer programmer from Minsk, Belarus. He moved to Ann Arbor with his family in 1994 and was employed in the Information Technology department at Cayman. In November 2004, when he was 37, it was discovered that he had a large, invasive tumor of the nasal sinuses eroding upward through the cribriform plate. He underwent a subcranial resection of undifferentiated high-grade cancer of the right nasal cavity and anterior cranial fossa in January 2005. He subsequently underwent chemotherapy with Cisplatin (40 mg/m², 6 weekly sessions) and radiation therapy (24 5-days-a-week sessions). He was symptomatically and radiographically free of disease until October of 2005, when several foci of recurrent tumor where found on MRI, mainly growing in the dura. A biopsy of one tumor from the right parietal dura was obtained by craniotomy on November 9, 2005. The 2.5 × 3 cm specimen was divided into 18 samples and distributed between University of Michigan Pathology, ...

The middle cranial fossa (latin: fossa cranii media) is a region of the internal cranial base between the anterior and posterior cranial fossae, it lies deeper and is wider than the anterior cranial fossa.
The middle fossa, deeper than the anterior cranial fossa, is narrow medially and widens laterally to the sides of the skull. It is separated from the posterior fossa by the clivus and the petrous crest.It is bounded in front by the posterior margins of the lesser wings of the sphenoid bone, the anterior clinoid processes, and the ridge forming the anterior margin of the chiasmatic groove; behind, by the superior angles of the petrous portions of the temporal bones and the dorsum sellæ; laterally by the temporal squamæ, sphenoidal angles of the parietals, and greater wings of the sphenoid. It is traversed by the squamosal, sphenoparietal, sphenosquamosal, and sphenopetrosal sutures. It houses the temporal lobes of the brain. ...
Cancer of the nasal acavity and paranasal sinuses is relatively rare, ocurs more often in men (2:1) and usually appears after 40 years, (except minor salivary gland origin, lymphoma, or esthesioneuroblastoma). Squamous cell carcinoma is the most common type, followed by adenocarcinoma. These tumors have a propensity to grow slowly, insidiously towards the anterior skull base and orbit. Imaging is essential since it allows a precise tumor mapping, a key element for therapeutic planning. CT allows to visualize the bony structures, particularly the internal orbital wall and cribriborm plate. MR permits to differentiate between the tumor, which most often is seen as a T2 weighted low signal intensity area, and inflammatory tissue which shows up bright. In addition it can displays meningeal and intracerebral involvement. MR information can help selecting the correct surgical approach, particularly a combined neurosurgical-ENT approach if the anterior cranial fossa has to be removed ...
What is the Cribriform Plate? In the human skull, Cribriform Plate is a significant part that separates the brain from the nasal cavity.

The word fontanel comes from the French fontaine for fountain. The medical term fontanel is a soft spot of the skull. The soft spot is soft precisely because the cartilage there has not yet hardened into bone between the skull bones. There are normally two fontanels, both in the midline of the skull, one (the anterior fontanel) well in front of the other (the posterior fontanel). ...

The skull is a complex structure; its bones are formed both by intramembranous and endochondral ossification. The skull roof bones, comprising the bones of the facial skeleton and the sides and roof of the neurocranium, are dermal bones formed by intramembranous ossification, though the temporal bones are formed by endochondral ossification. The endocranium, the bones supporting the brain (the occipital, sphenoid, and ethmoid) are largely formed by endochondral ossification. Thus frontal and parietal bones are purely membranous.[6] The geometry of the skull base and its fossae, the anterior, middle and posterior cranial fossae changes rapidly. The anterior cranial fossa changes especially during the first trimester of pregnancy and skull defects can often develop during this time.[7]. At birth, the human skull is made up of 44 separate bony elements. During development, many of these bony elements gradually fuse together into solid bone (for example, the frontal bone). The bones of the roof of ...

The blastema covers almost all of the lateral surface of the cartilaginous skull. A small part of the occipital cartilage, including the transverse process, part of the squama and occipital neural arch, part of the orbital wing of the sphenoid, and part of the lateral surface of the nasal capsule, are uncovered (figs. 9 and 15). Into the blastema covering the squamal cartilage, rather than into the cartilage itself, are inserted the various occipital muscles (figs. 14 and 15). The blastema covering the squama and the lateral surface of the otic capsule probably fases later with the perichondrium, but at this stage it seems to be continuous with the rest of the blastemal wall which later gives rise to membrane bones. It is in the sphenoidal and frontal regions that the blastema greatly predominates over the cartilage. All of the lateral wall of the middle cranial fossa consists of blastema and the greater part of the floor (as well as all of the lateral wall of the anterior fossa) is likewise ...

It is in the sphenoidal and frontal regions that the blastema greatly predominates over the cartilage. All of the lateral wall of the middle cranial fossa consists of blastema and the greater part of the floor (as well as all of the lateral wall of the anterior fossa) is likewise ...

The Skull Base, upon which the Brains undersurface rests, has three main regions. The Anterior (front) Cranial Fossa is the region located above the eyes and includes structures such as: the Olfactory Bulbs, the Nasal Cavity, and Cranial Nerves (1 & 2 and sections of 3, 4 & 6) that control vision, as well as movement of the eyeballs. The Middle Cranial Fossa is the region containing the dense, boney Petrous Ridge, and houses the Internal Carotid Artery, along with sections of the Cranial Nerves (5 & 7) that control chewing and facial sensation. The Middle Cranial Fossa also contains the Cavernous Sinus, an extremely difficult structure from which to remove tumors. The Posterior (back) Cranial Fossa is where the Internal Auditory Canal (IAC) and the Cranial Nerves (7 & 8) responsible for hearing, facial expression and balance are located; the Jugular Vein also passes through this region. Of the 24 highly specialized Cranial Nerves, which control many vital functions of our head and neck, 18 ...

A newborns shoulders and hips are narrow, the abdomen protrudes slightly, and the arms and legs are relatively short. The average birth weight of a full-term newborn is approximately 7 ½ lbs.(3.2 kg), but is typically in the range of 5.5-10 pounds (2.7-4.6 kg). The average total body length is 14-20 inches (35.6-50.8 cm), although premature newborns may be much smaller. The Apgar score is a measure of a newborns transition from the uterus during the first minutes of life. A newborns head is very large in proportion to the rest of the body, and the cranium is enormous relative to his or her face. While the adult human skull is about 1/8 of the total body length, the newborns is about 1/4. At birth, many regions of the newborns skull have not yet been converted to bone, leaving soft spots known as fontanels. The two largest are the diamond-shaped anterior fontanel, located at the top front portion of the head, and the smaller triangular-shaped posterior fontanel, which lies at the back of ...
