This study reported the successful management of end-stage otitis externa-media in four dogs using total ear canal ablation (TECA) combined with bulla osteotomy and cure age. All animals were premedicated with atropine, butorphanol, and diazepam. General anaesthesia was induced with propofol and maintained with isoflurane in oxygen. TECA with partial lateral bulla osteotomy was performed in all cases, followed by thorough cure age to ensure complete removal of infected and necrotic tissue. Postoperative care included administration of antibiotics, analgesics, and nervine tonics, along with daily antiseptic wound management. Follow-up evaluations over six weeks demonstrated complete clinical recovery in all dogs, with no observed complications such as facial nerve paralysis or fistula formation. These findings support TECA combined with bulla osteotomy and cure age as an effective and reliable surgical approach for the treatment of advanced otitis externa and media in dogs.
