This clinical study attempts to evaluate the effectiveness of Eustachian tube function in 30 ears, 11-29 months after insertion of the Silastic Eustachian tube prosthesis (SETP). Indications for the SETP were limited to persistent Eustachian tube dysfunction. Preoperatively, 13 patients had intact tympanic membranes with persistent serous otitis media. Seventeen patients underwent tympanoplasty and demonstrated persistent serous otitis media in the opposite ear. Postoperatively, aeration of the middle ear was evaluated by tympanometry, microscopic examination, and myringostomy. Microphotographs demonstrate the state of the middle ear. Histology of the middle ear mucosa was obtained in a few cases. Ninety-six percent of the ears with an SETP demonstrated confirmed persistent Eustachinan tube dysfunction beginning an average of six months after insertion. Complications were common.
本临床研究旨在评估30只耳朵在插入硅橡胶咽鼓管假体（SETP）后11至29个月时咽鼓管功能的有效性。SETP的适应症仅限于持续性咽鼓管功能障碍。术前，13例患者鼓膜完整，患有持续性浆液性中耳炎。17例患者接受了鼓室成形术，对侧耳朵患有持续性浆液性中耳炎。术后，通过鼓室导抗图、显微镜检查和鼓膜造孔术评估中耳的通气情况。显微照片显示了中耳的状态。少数病例获取了中耳黏膜的组织学检查结果。96%植入SETP的耳朵在植入后平均6个月开始出现持续性咽鼓管功能障碍。并发症很常见。
