Uludağ University, School of Medicine Department of Neurosurgery, Bursa, Turkey Fibrous dysplasia is a congenital, nonfamilial, metabolic disturbance that produces 2.5% of all osseous tumors, and more than 7% of all nonmalignant tumors in bone. Involvement of the temporal bone, however, is relatively rare. An 8-year-old girl presented with progressive hearing loss. She had a mass in the left external acoustic meatus and hearing loss in her left ear. Radiological studies revealed a temporal mass. The patient underwent two surgeries in 2 months, and the mass was totally excised. A postoperative neurologic examination revealed left facial paralysis. Histological study identified the mass as fibrous dysplasia of bone. After 5 years of follow-up, there were no signs of residual tumor or recurrence of the disease. When indicated, total excision with extensive reconstruction is the treatment of choice for this type of bone neoplasm. Keywords : Fibrous dysplasia; temporal bone; tumor; acoustic meatus
