This study reports long-term results of blind sac closure of the external auditory canal performed for various pathologies, compares the complication rates and the need for revision surgery.
This study is a retrospective review. Ninety-six cases of blind sac closure performed for various pathologies were included in this study. The primary pathologies included extensive mucosal disease in an open mastoid cavity, cholesteatoma, skull base lesion, cerebrospinal fluid leak, and osteoradionecrosis of the temporal bone. Preoperative history, postoperative complications, and the need for revision surgery were evaluated.
The most common indication for blind sac closure in our series involved skull base lesions (62.5%). The mean follow-up period was 46 months (4 months - 20 years). The total complication rate related to blind sac closure was 10.4%. The median time between surgery and long-term complications was 5.5 years. Patients with chronic mucosal disease had the highest rate of complications.
Blind sac closure of external meatus can be effectively performed for different pathologies. Long-term follow-up with patients is necessary. Patients with chronic mucosal disease have the highest complication rates.
本研究报告了因各种病变行外耳道盲袋关闭术的长期结果，比较了并发症发生率和需要修正手术的情况。
本研究为回顾性研究。共纳入 96 例因各种病变行外耳道盲袋关闭术的患者。主要病变包括开放乳突腔广泛黏膜疾病、胆脂瘤、颅底病变、脑脊液漏和颞骨放射性骨坏死。评估了术前病史、术后并发症和需要修正手术的情况。
本系列中最常见的行外耳道盲袋关闭术的指征是颅底病变（62.5%）。平均随访时间为 46 个月（4 个月-20 年）。与外耳道盲袋关闭术相关的总并发症发生率为 10.4%。手术和长期并发症之间的中位数时间为 5.5 年。慢性黏膜疾病患者的并发症发生率最高。
外耳道盲袋关闭术可有效治疗不同病变。需要对患者进行长期随访。慢性黏膜疾病患者的并发症发生率最高。
