Paradigm of Ear Canal Ablation (ECA) and Clinical Results of Bulla Osteotomy

Total Ear Canal Ablation (TECA) and Bulla Osteotomy are surgical procedures in veterinary medicine utilized to address various ear-related conditions, primarily in dogs and cats. TECA is indicated for chronic inflammatory ear diseases, trauma, neoplasia, cholesteatoma, congenital malformations, and failed prior surgeries. It involves the complete removal of the ear canal, often coupled with Lateral Bulla Osteotomy (LBO) for middle ear issues. LBO is essential for conditions like otitis media. Preoperative evaluations encompass physical exams, otoscopy, and imaging, with antibiotic and analgesic administration. Surgical equipment includes specialized instruments like rongeurs, curettes, and retractors. The surgical procedures require meticulous technique to ensure patient safety and involve incisions, dissection, and removal of affected tissue, with a focus on preserving vital structures like the facial nerve. Postoperative care includes pain management, bandaging, swelling control, antibiotic therapy, and drain/suture management. Potential complications include nerve damage and hearing loss. TECA and Bulla Osteotomy are crucial interventions for alleviating chronic ear problems in animals, enhancing their overall quality of life.
