Complex Case of Skull Base Osteomyelitis Secondary to Chronic Otitis Media

Abstract

We present a case of a 58-year-old male with type II diabetes managed with metformin and insulin, who presented to the clinic with left chronic otitis media, persistent drainage, a stenotic meatus, and a prior history of 3 canal wall-down mastoidectomies and antibiotic therapy. A revision tympanoplasty with mastoidectomy was performed, and during the postoperative period, the patient had persistent pain and otorrhea, which were managed with opioids and several courses of antibiotic therapy. After symptoms persisted, imaging and culture ultimately led to the diagnosis of fungal skull base osteomyelitis, which was eventually treated successfully. While these complications are rare, their likelihood is increased with treatment delay and in the immunocompromised patient. Close management of immunocompromised patients, including diabetic patients, is vital in identifying complications early to aid in timely diagnosis and treatment to lead to the best possible outcome. © The Author(s) 2023.
