Objective: To analyze the impact of patient selection and auditory monitoring on hearing results after middle fossa craniotomy approach for resection of a vestibular schwannoma (VS).
Study Design: Retrospective case review.
Setting: Tertiary referral center.
Patients: Patients undergoing a middle fossa craniotomy for resection of VS at a single institution between 1995 and 2006 were included in the study population. Patients presenting with Neurofibromatosis Type 2 or who underwent a combined approach (middle fossa and retrosigmoid) were excluded.
Main Outcome Measures: Hearing preservation as measured by serial audiograms.
Results: Seventy-seven patients were identified. Before excluding patients with cochlear fossa enhancement and the use of auditory monitoring, 47% of the patients maintained serviceable hearing (American Academy of Otolaryngology-Head and Neck Surgery Class A or B). By selecting tumors that did not involve the cochlear fossa and using auditory monitoring, serviceable postoperative hearing was preserved in 76% of the patients.
Conclusion: Modification of our selection criteria for surgery and the use of auditory monitoring have improved our hearing results for patients undergoing a middle fossa approach for resection of VS from 47% to 76%.

Background And Objectives: The middle fossa approaches are tremendously versatile for treating small vestibular schwannomas, selected petroclival meningiomas, midbasilar trunk aneurysms, and lesions of the petrous bone. Our aim was to localize the internal acoustic canal and safely drill the petrous apex with these approaches. This study demonstrates a new method to locate the internal acoustic canal during surgery in the middle fossa.

Osimertinib has emerged as the standard first-line treatment for advanced non-small cell lung cancer (NSCLC) with EGFR mutations, offering improved tolerability and demonstrating superior efficacy against brain metastases in comparison with other tyrosine kinase inhibitors. The Meckel's cave is a dural recess in the posteromedial part of the middle cranial fossa that acts as a conduit for the trigeminal nerve between the anterior pontine cisterna and the cavernous sinus, and houses the Gasserian ganglion and proximal radicle of the trigeminal nerve. Trigeminal neuropathy, characterized by numbness and dysesthesia of the skin and mucous membranes of the face, poses diagnostic challenges and often requires differentiation from conditions, such as compression neuropathy, inflammation, and drug-induced reactions.

Purpose And Background: The trigeminal artery is a rare anatomical variant, representing an embryonic vestige of the anastomosis between the internal carotid artery and the posterior circulator system, that can be asymptomatic or could have vast clinical manifestations produced by insufficient flow or by vascular nervous conflicts. This study is an anatomical presentation of 3 trigeminal artery cases observed at Medimar Imagistic Services Constanta.
Methods: The 3 trigeminal artery cases were discovered on a 860 magnetic resonance angiographies (0.

The reported complications after arthrocentesis of the temporomandibular joint are rare, which makes it to an outpatient and safe oral and maxillofacial surgical procedure. A penetration into the middle cranial fossa is an extremely rare but serious complication for the conventional needle arthrocentesis. The simple technical modification described herein could help to easily retain the puncture depth via an endodontic silicone stopper to avoid this rare complication.

Background: The skull base ligaments have been extensively studied in the literature due to their clinical and surgical significance. The posterior petroclinoid fold (PPCNF) and petroclival ligament (PCVL) are two adjacent structures that have barely been studied and are frequently confused. The present study uses an innovative classification system to investigate the PPCNF and PCVL ossification patterns.
