Abstract

The present study was carried out on 88 dogs presented for treatment of chronic otitis externa. Out of 88 dogs, 74 (84.09%) were treated medically and remaining 14 by surgical treatment. Out of these 14, seven dogs were treated by Zepp's aural resection and the remaining 7 by vertical ear canal ablation. The various clinical signs of otitis externa recorded were head shaking, scratching, pain, odour, ear discharges and head tilt. Visual examination of ear canal revealed hyperplasia, thickening, ulceration, stenosis and calcification of ear canals in the 14 cases treated surgically. The cultural examination of the ear discharge resulted in isolation of Staphylococcus in 51 cases, Pseudomonas in 24 cases and E. coli in 13 cases. Ciprofloxacin was found to be the most effective drug in 31 cases, followed by gentamicin in 25 cases, chloramphenicol in 22 cases, amoxycillin in 6 cases and oxytetracycline in 4 cases. All the dogs treated with Zepp's aural resection recovered uneventfully. All the 7 dogs that were treated by performing vertical ear canal ablation also responded to the treatment.
