Abstract

OBJECTIVE

To evaluate microdebrider eustachian tuboplasty for treatment of patients with eustachian tube dysfunction.

STUDY DESIGN

A prospective study of 20 patients with eustachian tube dysfunction who underwent microdebrider eustachian tuboplasty (mETP) was performed at an academic medical center. Surgery involved use of a microdebrider to remove hypertrophied mucosa from the posterior eustachian tube cushion. All patients had concurrent sinonasal disease and underwent endoscopic sinus surgery at the time of mETP.

RESULTS

There were no surgical complications. Following mETP, subjective symptoms of ear blockage improved in 14 of 20 patients (70%). Mean pure tone average improved by 6 dB (27 dB pre-op vs 21 dB post-op; P = 0.013). Abnormal tympanogram improved in 11 of 17 patients (65%). Failure of the procedure correlated with severity of mucosal disease as measured by both elevated tissue eosinophil count and advanced sinus CT stage (P = 0.018 and P = 0.014, respectively). Mean follow-up was 13 months (range 3-34 months).

CONCLUSION

Microdebrider eustachian tuboplasty appears to be a safe procedure for the treatment of eustachian tube dysfunction.

摘要

目的

评估微型切割器咽鼓管成形术治疗咽鼓管功能障碍患者的效果。

研究设计

在一家学术医疗中心对20例接受微型切割器咽鼓管成形术（mETP）的咽鼓管功能障碍患者进行了前瞻性研究。手术包括使用微型切割器从咽鼓管后垫去除肥厚的黏膜。所有患者均合并鼻窦疾病，并在mETP时接受了鼻内镜鼻窦手术。

结果

无手术并发症。mETP后，20例患者中有14例（70%）的耳闷主观症状得到改善。平均纯音平均值提高了6 dB（术前27 dB，术后21 dB；P = 0.013）。17例患者中有11例（65%）的鼓室导抗图异常得到改善。手术失败与黏膜疾病的严重程度相关，通过组织嗜酸性粒细胞计数升高和鼻窦CT分期进展来衡量（分别为P = 0.018和P = 0.014）。平均随访时间为13个月（范围3 - 34个月）。
