目的:探讨咽鼓管功能对听骨链重建术效果的影响。方法:采用钛质人工听骨行骨链重建术及鼓室成形术。部分患者有不同程度的咽鼓管闭塞,对于咽鼓管通畅,部分及完全闭塞等情况于术前检查,术中探通,术后鼓膜切开植管法等处理。结果:术前显示咽鼓管通畅和术中咽鼓管探通者,术后效果和听力恢复较好。咽鼓管闭塞者术后均应行鼓膜切开植管术等处理以挽救患者听力。结论:咽鼓管功能对听骨链重建手术的成功和术后听力效果有重要影响。
Objective: To investigate the effect of eustachian tube function on the reconstruction of ossicular chain. Methods: Titanium artificial ossicular chain reconstruction and tympanoplasty were performed. Some patients have different degrees of eustachian tube occlusion, eustachian tube patency, partial and complete occlusion and other conditions in the preoperative examination, intraoperative exploration, postoperative tympanotomy incision and other treatment. Results: Preoperative eustachian tube patency and intraoperative exploration of eustachian tube, postoperative effects and hearing recovery better. Eustachian tube occlusion after surgery should be tympanotomy incision and other treatments to save the patient’s hearing. Conclusion: Eustachian tube function plays an important role in the success of ossicular chain reconstruction and postoperative hearing.
