Abstract

External auditory exostoses (EAE) are benign growth of the bone of the external ear canal and commonly asymptomatic. Patients with EAE may complain conductive hearing loss, frequent external otitis, ear pain, ear wax accumulation, and or tinnitus.  The diagnosis of EAE is mainly based on clinical, surgical findings and  histopathology examination.  Therapy of  EAE depends on  patient’s symptoms.  Removal of EAE or surgical treatment is considered if EAE enlarge and cause oclusion greater than 80% of  external ear canal, conductive hearing loss or recurrent external otitis.  Incision approaches include transmeatal, postauricular, and endaural.

A 65 year old man has been reported with bilateral EAE.  The patient has underwent canaloplasty to remove the right exostoses because  of conductive hearing loss  and occlusion more than 80% was presented on right ear. artikel lengkap
