Objective: The anterior petrosectomy, also known as Kawase's approach and the retrosigmoid intradural suprameatal approach (RISA) have both been used to reduce the petrous apex and to access the petroclival region. Our goal was to compare the volumes and 3-dimensional shapes of bony resection obtained through each approach, while trying to resemble realistic surgical settings.

Methods: Five cadaveric specimens totaling 10 sides were dissected and analyzed. Read More

Vestibular schwannomas have an estimated incidence of 1.09/100,000 people, representing 6-10% of intracranial tumors. Rarer giant vestibular schwannomas are defined by an extrameatal diameter of ≥4cm and can be difficult to treat because of displacement and compression of local neurovasculature and the potential for multicompartment involvement.

Background: Skull base lesions within the middle cranial fossa (MCF) remain challenging. Recent reports suggest that transorbital endoscopic approaches (TOEAs) might be particularly suitable to access the MCF and expose the lateral wall of the cavernous sinus (CS) and the Meckel's cave (MC).

Methods: The present study was developed to compare the nuances of the subtemporal approach (STA) with those of the lateral TOEA (LTOEA) to the MCF and posterior cranial fossa (PCF) in cadaveric specimens. Read More

Objective: IgG4-related disease (IgG4-RD) involving the temporal bone is an uncommon and underrecognized pathology often mistaken for malignancy. This systematic review is the first that aims to thoroughly analyze IgG4-RD of the temporal bone.

We report magnetic resonance imaging (MRI) in a case with otosyphilis, which is a rare manifestation of neurosyphilis. A 50-year-old male presented with progressive hearing loss on the left side and recent-onset palsy of the left 7th and 12th cranial nerves. Computed tomography imaging showed destructive bone lesions involving the petrous temporal bone, middle ear, and mastoid region with a pathognomonic pattern of bone destruction depicted in the volume rendering technique images.
