A case of fibrous dysplasia of the pediatric temporal bone

Abstract

Fibrous dysplasia is a benign bone disorder of unknown etiology characterized by progressive replacement of bone by abnormal proliferative fibrous tissue. We herein report a case of fibrous dysplasia involving the left temporal bone. A twelve-year-old female with left progressive hearing loss was referred to our hospital. Otoscopic examination revealed an obstructed left external auditory canal. CT showed the diffuse ground-glass appearance of the left temporal bone. We conducted meatoplasty and mastoidectomy under general anesthesia. The postoperative period was uneventful and air-bone gap has disappeared in two years and eight months.
