Prevalence of Petrosquamosal Sinus and Its Clinical Significance: Radiologic Study and Meta-analysis.

Objective: The petrosquamosal sinus (PSS) is clinically important as it represents a potential hemorrhagic hazard during neurosurgical procedures. This double-approach radiologic study and meta-analysis aimed to assess the imaging characteristics of the PSS on computed tomography (CT) and systematically analyze its prevalence to improve imaging accuracy and assist in neurosurgical management.

Methods: The retrospective radiologic study included CT scans of 388 patients aged 18 years or older.
