✓ The authors report the case of a newborn baby girl who had a large extracerebral neural tissue mass in the right middle cranial fossa which extended into the oropharynx through an enlarged foramen ovale. The surgical specimen comprised various kinds of neural tissue, including primitive neuroepithelium, mature as well as immature neurons and glia, myelinated fibers, ependyma, choroid plexus, ocular pigmented epithelium, and a number of calcospherites. The mass was partially covered by its own leptomeninges. The question of whether this mass is a true neoplasm or a heterotopia is discussed.

Introduction The greater wing of sphenoid presents various foramina, of which the foramen ovale is one important foramen through which advanced surgical therapeutic and diagnostic procedures related to the middle cranial fossa are performed. Materials and Methods A total of 40 dried adult skulls of unknown gender and age, obtained from the Department of Anatomy of the JSS medical College, Mysuru, Kamakata, India. The length and the width of the foramen ovale were measured using digital sliding calipers (tiny deal 150 mm SS digital caliper with LCD display, Kristeel-Shimwa industries, Bombay, India). Results The mean length of the foramen ovale was 0.745 ± 0.31 cm on the right side (RS), and 0.68 ± 0.15 cm on the left side (LS). The mean width was 0.6 ± 0.17 cm on the RS, and 0.56 ± 0.14 cm on the LS. Conclusion The knowledge of variations in the length and breadth of the foramen ovale is of immense importance in neurosurgery during various invasive surgical procedures, such as percutaneous trigeminal rhizotomy, and in the biopsy of cavernous sinus tumors and of Meckel cave lesions.

INTRODUCTION: The foramen ovale is present in sphenoid bone which transmits the mandibular nerve, accessory meningeal artery, emissary vein and the lesser petrosal nerve. This study was conducted on a total 100 si MATERIALS & METHODS: des in 50 dry adult skulls. The shape of foramen will be determined by a visual examination. Margins of foramen were carefully observed for the abnormal bony outgrowths such as sharp bony projections (spine), small blunt bony projection (tubercle), bony plate and bony bar. We obs RESULTS: erved the variations in shape of foramen ovale. We found oval, almond, round, triangular, slit like and irregular shaped in 62%, 20%, 9%, 4%, 3% and 2% foramina ovale respectively. We also observed abnormal bony outgrowths in the foramen ovale like spines, tubercles, bony plate and bony bar. Abnormal bony bar was dividing the foramen ovale in 2 compartments (Anterior and Posterior). The preci CONCLUSIONS: se knowledge of variations of foramen ovale is of valuable contribution for neurosurgeons to development of new and different techniques to approach the middle cranial fossa. In our study we found , 100% tubercles and 80% spines were arising from anterior margin of foramen ovale. These ndings are important for neurosurgeons to approach middle cranial fossa via foramen ovale for neurosurgical and diagnostic procedures like percutaneous biopsy of cavernous sinus tumours, electroencephalographic analysis, microvascular decompression , percutaneous trigeminal rhizotomy and administration of anaesthesia to the mandibular nerve. Surgeons should avoid to go , close to the anterior margin of foramen ovale as spines and tubercles could interrupt the procedures.

Foramen Of Vesalius

All 377 dry skulls were examined for the occurrence and morphometry of the foramen of Vesalius (FV) both in the middle cranial fossa and at the extracranial view of the skull base. There were 25.9% and 10.9% of FV found at the extracranial view of the skull base and in the middle cranial fossa, respectively. Total patent FV were 16.1% (11.9% unilaterally and 4.2% bilaterally). Most FV were found in male and on the left side. Comparatively, FV at the extracranial view of the skull base had a larger maximum diameter. The distance between FV and the foramen ovale (FO) was as short as2.05±1.09 mm measured at the extracranial view of the skull base. In conclusion, although the existence of FV is inconstant, its occurrence could not be negligible. The proximity of FV to FO should remind neurosurgeons to be cautious when performing the surgical approach through FO.

AbstractAim:This study aimed to determine whether or not the middle cranial fossa dural plate is located lower (i.e. more caudally) in patients with chronic otitis media, relative to adjacent structures.Methods:The authors retrospectively investigated computed tomography temporal bone scans of 267 ears of 206 patients who had undergone surgery with a diagnosis of chronic otitis media, together with scans of 222 ears of 111 patients without chronic otitis media. The depth of the middle cranial fossa dural plates was recorded.Results:The mean depth of the middle cranial fossa dural plate was 4.59 mm in the study group and 2.71 mm in the control group (p < 0.001). The middle cranial fossa dural plate was located lower in the right ear in both the study and control groups.Conclusion:The middle cranial fossa dural plate was located lower in patients with chronic otitis media, and in the right ears of both patients and controls. Surgeons should take this low location into consideration, and take extra care, during relevant surgery on patients with chronic otitis media.

Cyst Fenestration

✓ The best operative intervention for children with arachnoid cysts remains the subject of controversy. Recent reports stress that craniotomy for cyst fenestration is associated with a low incidence of morbidity and mortality and may leave the child shunt-independent. The cases of 40 pediatric patients with arachnoid cysts treated between 1978 and 1989 are reported. Five children with mild symptoms and small cysts that remained stable on follow-up studies have not required surgical intervention. Of 15 patients with cysts initially treated by fenestration, 10 (67%) showed no clinical or radiographic improvement postoperatively and have undergone cyst-peritoneal (eight patients) or ventriculoperitoneal (VP) shunting (one patient), or revision of a VP shunt placed for hydrocephalus before cyst fenestration (one patient). Two other patients with existing VP shunts required no further procedures. Thus, only three (20%) of 15 patients initially treated by fenestration remain shunt-independent after a median follow-up period of 8 years. The 20 other patients were initially treated by cyst shunting and all improved postoperatively; shunt revision has been necessary in six (30%) of these 20 patients because of cyst recurrence, Cyst location influenced the success of shunt treatment; none of the seven middle cranial fossa cysts treated by shunting have required revision, but results with cysts in other locations were less favorable. In all locations, though, shunting was more successful than fenestration. It is concluded that cyst-peritoneal or cyst-VP shunting is the procedure of choice for arachnoid cysts in most locations, including those in the middle cranial fossa.

Haemangioma of the thyroid gland is extremely rare. We report a case of a cavernous haemangioma of the neck that was located both inside and outside the thyroid gland of a 21-year-old man. Ultrasonography of the neck revealed numerous calcified nodules. Computed tomography (CT) showed a large calcified soft tissue mass in the right lobe of the thyroid. Based on the imaging findings a papillary thyroid carcinoma was suspected, but examination of the surgical specimen revealed a huge cavernous haemangioma containing numerous phleboliths.

Objectives: The structures passing through the foramen spinosum and its neurovascular relationships are of great importance for surgical approches directed to middle cranial fossa. The aim of the present study was to examine the number and location of the foramen spinosum (FS) in 3D-CT images. Methods: The study was retrospectively conducted on 3D-CT images of 177 adults. Firstly, the transverse section passing through the upper edge of the orbit, extending parallel to the Frankfurt plane was chosen. Then, the x and y-axes were determined on that transverse section. The coordinates, number, and location of the FS with respect to the foramen ovale (FO) were identified accordingly on x and y-axes. Results: While 1 FS was present in 90.96% of a total of 354 sides of 177 heads, there were 2 FS and 3 FS in 8.76% and 0.28% of the sides, respectively. The FS was located posterolaterally in 97.68%, posteriorly in 2.06%, and laterally in 0.26% with respect to the FO. In terms of FS coordinates, there was no statistically significant difference between gender and sides in the distance of the FS to the x-axis, but there was a statistically significant difference between gender and sides in the distance of the FS to the y-axis. Conclusion: Evaluation of the number of the FS and its location would help identifying and preserving neighbouring neurovascular structures during surgical interventions directed to the middle cranial fossa.
