Thirty dogs with end-stage otitis were treated by either unilateral or bilateral total ear canal ablation and lateral bulla osteotomy. Otitis was considered end stage when the horizontal ear canal was collapsed, stenotic, or occluded in conjunction with chronic infection of the external and middle ear. The dogs were evaluated clinically and radiographically for 4 to 63 months. The frequency of scratching, head shaking, aural drainage, and para-aural fistulation was significantly decreased. Abnormal ear carriage and head tilt were not changed. The results in 23 dogs were graded as excellent or improved. One dog died of intraoperative hemorrhage. Complications during the period from suture removal to follow-up included para-aural fistulation (3 dogs), facial nerve paralysis (5 dogs), and head tilt (3 dogs).
30只患有终末期中耳炎的犬接受了单侧或双侧全耳道切除术及外侧鼓泡切开术治疗。当中耳水平耳道塌陷、狭窄或闭塞并伴有外耳道和中耳慢性感染时，中耳炎被视为终末期。对这些犬进行了4至63个月的临床和影像学评估。抓挠、摇头、耳漏和耳周瘘管形成的频率显著降低。耳部异常姿态和头部倾斜未改变。23只犬的治疗结果被评为优秀或改善。1只犬死于术中出血。从拆线到随访期间的并发症包括耳周瘘管形成（3只犬）、面神经麻痹（5只犬）和头部倾斜（3只犬）。
