Abstract
Otohematoma is a fairly comon disease in otolaryngologic clinics. Many physicans have been chalanged with various method most of these treatments are recurrent problems and eventually become the cauliflower ear. A treatment involves a total excision of the newly formed fibroneocartilaginous layer. If hematoma persists, perichondrium becomes irregular by thickned fibroneoca-rtilage formation. We treated 11 patients with otoplasty to remove fibroneocartilage under local anesthesia. We found that the pe-richondrium formed severe fibroneocarilage and organization after 2 weeks. We studied the sequence of pathological changes that occurs after injury. (Korean J Otolaryngol 2003 ;46 :198-201)
