Abstract

Rachana Dhakal, Ramesh Makaju and Ashish Dhakal

External auditory canal osteomas are found to be rare benign bony neoplasms that are usually unilateral and solitary. Symptoms are rare that includes hearing loss, tinnitus, vertigo and pain. Diagnosis is based on clinical examination, radiographic imaging and histopathology. We describe a case of 26-year-old male with a complaint of aural fullness for one week associated with decreased hearing. On physical examination, the posterior wall of right auditory canal was completely occluded by a mass, which was fixed. On histopathological examination, hematoxylin and eosin stained slides revealed a mass of cancellous bone surfaced by stratified squamous epithelium. Fibrovascular channels were seen with small vessels.
