A total of 311 patients with a unilateral acoustic neurinoma were operated on via the enlarged middle cranial fossa approach. A total tumor removal was achieved in 98% of cases. The mortality was 0.6%. Overall in acoustic neurinoma surgery, the percentage rates of meningitis (1.6%), cerebrospinal fluid fistula (1.6% requiring surgery), and neurological deficits were fairly low. The facial nerve...

A 53-year-old woman presented with left mandibular area pain, trismus, and facial numbness that had persisted for 4 years. Physical examination revealed a 3×5 cm, hard, non-tender, and round mass on the left mandibular area. Computed tomography and magnetic resonance imaging revealed an expansile tumor involving the left mandibular ramus and temporomandibular joint area with bone destruction, e...

Raeder described five patients with mixed features of trigeminal nerve pathology and oculosympathetic impairment, with or without other cranial nerve lesions. This constellation of clinical features drew the original author’s attention to the paratrigeminal region as a likely site for the causative lesion in this syndrome. An analysis of the anatomy of the oculosympathetic innervation supports ...

A case of widespread spinal sarcoma is described with meningeal infiltration, involvement of the anterior cranial fossa complicated by aplastic anaemia and visceral metastases.

options are limited and consist mostly of patient education, prognostication, limitation of further damage, and appropriate ear, nose, and throat (ENT) referral. The ear is surrounded by the middle cranial fossa superiorly, the mastoid air cells posteriorly, the cranial vault medially, and the temporomandibular joint and parotid glands anteriorly. Evaluation of these structures is a necessary p...

A 33-year-old man had dizziness for 3 days without provoking factors. Head CT demonstrated a mass in the left lateral anterior cranial fossa with calcification and cystic degeneration (figure 1, A–C). MRI showed an irregularly shaped mass with mixed signal and slight marginal enhancement (figure 1, D–F). He underwent mass resection with no recurrent dizziness during 12 months’ follow-up. On pat...

We reported a rare case of hemorrhagic epidermoid cyst located in the anterior cranial fossa. A 66-year-old female presented with progressive nausea and vomiting for one month. Computed tomography revealed a mixed high and low density mass in the right lateral frontal basal region, with a few stippled calcifications at its inferior wall. Magnetic resonance imaging showed that the lesion was lar...

BACKGROUND The pterion is a point of sutural confluence seen in the norma lateralis of the skull. The site is an important landmark in surgical approaches to the anterior and middle cranial fossa. OBJECTIVE This study was designed to determine the frequency of pterion types and anatomic positions of the pterion in dry human skulls of Nigerians in the South Eastern Zone. MATERIALS AND METHOD...

BACKGROUND Computed Tomography (CT) has become a widely used supplement to medico legal autopsies at several forensic institutes. Amongst other things, it has proven to be very valuable in visualising fractures of the cranium. Also CT scan data are being used to create head models for biomechanical trauma analysis by Finite Element Analysis. If CT scan data are to be used for creating individua...

Epidural hematoma of the posterior cranial fossa (EHPCF) is a rare complication in head injuries. Furthermore, nonspecific clinical signs and the rare occurrence of this lesion in craniocerebral injuries make the establishment of a diagnosis more difficult. The aim of the paper is to point to the advantages of early diagnosis. During the 1982-2008 period, 18 patients with EHPCF were operated on...
