Introduction Petrous apex cholesterol granulomas (PACGs) are uncommon lesions. Recurrence following transcranial or endonasal approaches to aerate the cyst occurs in up to 60% of cases. We describe the technical nuances pertinent to the endonasal endoscopic management of a recurrent symptomatic PACG and review the literature. Results A 19-year-old woman presented with a recurrent abducens nerve...

The gold standard treatment of PA CG counts on its surgical drainage and ventilation to prevent recurrence. Different surgical approaches have been described in the past to achieve draina...
