Clinical outcomes of dogs treated for end-stage otitis extema with total ear canal ablation (TECA) combining lateral bullar osteotomy (LBO) at Veterinary medical teaching hospital of Seoul National University from 2001 to 2003 were evaluated. In 14 dogs, 23 ears, the operation was successful in alleviating all clinical signs of otitis externa and media. The main complication after TECA combining LBO were facial nerve paralysis and the others were recurrent infection and the formation of fistula and cyst. Two cases were tumors. One was ceruminous gland adenoma and the other was squamous cell carcinoma. The operation successfully resolved the original problems in 100% (23 of 23) of the surgically treated ears of these dogs.
