Supraorbital Keyhole Versus Pterional Approach: A Morphometric Anatomical Study.

Objective: Although the supraorbital (SO) keyhole approach has a wide range of indications, its routine usefulness with the advance of current technology has not been fully evaluated. In an attempt to address this issue, a cadaveric morphometric analysis to the supra- and parasellar regions was performed, comparing the standard Pterional craniotomy (PT) with the SO keyhole.

Methods: ETOH-fixed and silicone-injected human cadaveric heads were used.

Spontaneous acute subdural hematomas. A clinical comparison with traumatic acute subdural hematomas.

A comparison was made between factors influencing survival in patients operated on for acute spontaneous subdural hematomas (ASSH) and other groups of patients operated for acute, post-traumatic, subdural hematoma reported in the literature. The data of 17 patients operated on for ASSH were collected. Four variables: early surgical treatment, high Glasgow Coma Scale score on admission, pupillary reactivity and age were statistically analyzed.

Gunshot wound of the atlas in a youth.

The case of a bullet retained, without causing neurological symptoms, in the anterior arch of a youth's atlas after a gun had been fired a short distance from his mouth is reported. The patient was managed with external stabilization.

Cavernous angioma of the VIIIth cranial nerve. A case report.

We report a case of a 24-year-old woman affected by a cavernous angioma of the right VIIIth cranial nerve associated with a venous angioma. The malformation was diagnosed by MRI, performed in relation to an acute onset of right anacusia. The case report is indicative that, even if unusual, an acute onset of an cerebellopontine angle syndrome can be subsequent to a bleeding cavernous angioma.

Surgically verified case of optic sheath nerve meningocele: case report with review of the literature.

Optic sheath meningocele is rare; only approximately 31 cases have been reported. The term optic sheath meningocele has recently been proposed by Garrity and Forbes to describe primary CSF cysts of the optic nerve sheath, without apical mass or malformation of the cranio-orbital junction. Presenting symptoms are often related to involvement of the optic nerve, with a slow or rapid decrease of visual acuity.
