To assess clinical findings and long-term outcome of dogs treated for recurrent middle ear infection that developed after total ear canal ablation and lateral bulla osteotomy.
Retrospective case series.
Of 94 dogs (142 ears) treated by means of total ear canal ablation and lateral bulla osteotomy for end-stage otitis, 9 developed recurrent middle ear infection.
Information regarding treatment and outcome were retrieved from the medical records.
Antibiotic treatment was attempted in 8 dogs, but failed to cure recurrent otitis media in 7 of 8 dogs. Seven dogs were treated by means of exploratory surgery, which consisted of ventral bulla osteotomy and tympanic curettage. One dog was cured, 1 developed another infection and was euthanatized, and the 5 remaining dogs developed another middle ear infection after the first exploratory surgery. Infection resolved after retained epithelium was removed from the tympanic cavity during a second exploratory surgery of the bulla in these 5 dogs.
Antibiotic treatment rarely is effective for resolving recurrent middle ear infection that develops after total ear canal ablation and lateral bulla osteotomy. Ventral bulla osteotomy and curettage can be a successful method of treatment, provided retained epithelium and debris are completely removed from the ear canal and tympanic cavity.
评估接受全耳道切除和外侧鼓泡切开术后发生复发性中耳感染的犬只的临床症状及长期预后。
回顾性病例系列研究。
94只（142只耳朵）因终末期中耳炎接受全耳道切除和外侧鼓泡切开术治疗的犬只中，9只发生了复发性中耳感染。
从病历中获取有关治疗及预后的信息。
8只犬尝试使用抗生素治疗，但8只中有7只未能治愈复发性中耳炎。7只犬接受了探查性手术，包括腹侧鼓泡切开术和鼓室刮除术。1只犬治愈，1只发生了另一次感染并实施安乐死，其余5只犬在首次探查性手术后发生了另一次中耳感染。在对这5只犬的鼓泡进行第二次探查性手术时，从鼓室清除残留上皮组织后感染得到解决。
抗生素治疗对于解决全耳道切除和外侧鼓泡切开术后发生的复发性中耳感染很少有效。腹侧鼓泡切开术和刮除术可能是一种成功的治疗方法，前提是从耳道和鼓室完全清除残留上皮组织和碎屑。
