Inferior mastoidectomy-hypotympanic approach for surgical removal of glomus jugulare tumors: an anatomical and radiologic study emphasizing distances between critical structures.

The technique of inferior mastoidectomy-hypotympanic dissection, with preservation of the middle and inner ear structures, has been established for radical surgical removal of glomus tumors involving the skull base. In order to study the gross anatomic differences and correlate with the computed tomography (CT) scan, 20 human temporal bones were dissected and accurate measurements between vital structures were made. This study revealed a wide variation in distances between the neurovascular structures, whereas the distances between inner ear structures were not statistically different. This original study of critical distances of gross topographic anatomical structures and CT correlation is very helpful indeed in the understanding of variations found in the surgical removal of lesions involving this important and challenging area of the skull base. The inferior mastoidectomy-hypotympanic dissection has been performed in the removal of six suitable tumors involving the jugular bulb area. This technique, combined with upper cervical dissection, is very useful for the radical removal of such neoplasms with preservation of external and middle ear structures as well as the function of the facial, eighth, and other lower cranial nerves.

Pediatric brain stem tumor presenting as a pure motor hemiparesis.

The clinical syndrome of pure motor hemiparesis occurs with lacunar lesions in the internal capsule or in the basis pontis in hypertensive adults. It has been described in three patients with brain stem tumors of which two were children. A 3 1/2 years old boy with a brain stem tumor which presented as pure motor hemiparesis is described.

A cavernous sinus cavernous hemangioma. Case report.

The case of a Turner's syndrome patient with an intracavernous hemangioma is presented. The rarity of this lesion is stressed, as is surgical removal without postoperative deficit, the role of estrogens in the pathogenesis, and the clinical and radiological findings.
