Published: January 2023

Approaching the petrous apex can be complex and fraught with danger. Identifying favorable pathology and gaining access endoscopically is a direct, fast, and minimally invasive. Supported by navigation, it can be safely used in the vicinity of vital structures. A mucocele requires creation of a wide drainage pathway and can be an ideal lesion for such an approach.

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.

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.

Hemifacial spasm (HFS) is a disorder that causes involuntary movements of the ipsilateral facial muscles because of vascular compression of the facial nerve. Microvascular decompression (MVD), a surgical procedure to detach the culprit vessel from the nerve is believed to be the most effective treatment for HFS. Nevertheless, in the rare case in which the vessel penetrates the nerve, positioning the vessel sufficiently far from the nerve is challenging.

Background And Objectives: The intraosseous subarcuate loop (SL) is a unique variant of the anterior inferior cerebellar artery (AICA), where a loop of the artery is trapped in the petrous bone's subarcuate fossa (SF). Recognizing this variant is crucial for planning cerebellopontine angle (CPA) surgeries; however, data regarding its frequency and management vary in the published literature. A cohort from a single center was studied using MRI to assess its prevalence, and the findings were compared with the existing literature.

Purpose: The aim of this study is to assess the clinical characteristics, classification, surgical approaches, interventional strategies, and treatment outcomes of patients with petrous bone cholesteatoma (PBC).

Methods: Observational retrospective study of patients with PBC managed by the senior author of this paper between 1995 and 2024 in a tertiary referral center. A literature review was made, identifying 16 articles.
