OBJECTIVE: This report describes a case of otogenic central skull base osteomyelitis (CSBO) requiring complex surgical intervention and reviews the literature on management of this entity. PATIENT: A 76-year-old man presented with a nearly 20-year history of chronic otomastoiditis and cholesteatoma with ultimate progression to severe CSBO with involvement of the petrous apex, clivus, and craniocervical junction. INTERVENTIONS: CSBO was managed with culture-directed antibiotic therapy, hyperbaric oxygen, and surgical intervention including serial combined endoscopic transmastoid and transsphenoidal debridements. MAIN OUTCOME MEASURES: Symptom resolution, antibiotic holiday, and stable disease on surveillance imaging. RESULTS: With antibiotic treatment and surgical debridement including creation of a drainage pathway from the skull base to the sphenoid sinus, intermittent stretches of disease quiescence were realized over the course of nearly a decade. Despite extensive debridement and skull base reconstruction, the patient ultimately succumbed to the disease process. CONCLUSIONS: CSBO poses significant management challenges to the otologist. Herein, we present a rare case of CSBO managed over a prolonged period of time with antibiotics and combined anterior and lateral skull base debridement.
