Persistent deep infection originating from remnants of an incompletely excised ear canal, or epithelium and debris left in the osseous ear canal or tympanic cavity after surgery total ear canal ablation and lateral bulla osteotomy can be debilitating. Clinical signs including pain elicited on deep palpation over the affected bulla or when opening the mouth, or draining sinuses may be delayed months to years. Localization of the nidus via CT imaging is important for surgical planning. Although antibiotic therapy usually reduces or eliminates the clinical signs of deep infection, relapses are common. Surgery more consistently results in permanent resolution.
源于未完全切除的耳道残余物、或在全耳道切除术和外侧鼓泡切开术后留在骨性耳道或鼓室中的上皮和碎屑的持续性深部感染可能会使人衰弱。临床症状包括在受影响的鼓泡上进行深部触诊或张口时引起的疼痛，或引流性窦道，这些症状可能会延迟数月至数年出现。通过CT成像确定病灶位置对于手术规划很重要。虽然抗生素治疗通常会减轻或消除深部感染的临床症状，但复发很常见。手术更有可能实现永久性治愈。
