Type 3 tympanoplasty is the surgery of choice for middle ear reconstruction in cases where an integral stapes suprastructure and mobile footplate are present.
The objective of this study was to obtain functional results after endoscopic type 3 tympanoplasty in chronic otitis media.
Prospective study including 24 patients who underwent endoscopic type 3 tympanoplasty, using PORP for ossicular chain reconstruction (OCR) and cartilage graft for tympanic membrane reconstruction. Audiograms were made preoperatively, and 6 months after surgery.
Dry, closed, self-cleaning ears were obtained in 91.7% of the cases. Mean preoperative air-bone gap (ABG) was 30.4dB, mean postoperative ABG was 16.7dB, dB gain of 13.6dB. ABG closure rate to 20dB or less of 79.2%, and to 10dB or less of 29.2%.
Endoscopic tympanoplasty and OCR is a valid option for surgeons who are comfortable with the use of endoscopes for middle ear surgery as it allows improved visualization of the prosthesis and graft placement during middle ear reconstruction.
对于存在完整镫骨上部结构和活动镫骨足板的病例，3型鼓室成形术是中耳重建的首选手术方法。
本研究的目的是获得慢性中耳炎患者行内镜下3型鼓室成形术后的功能结果。
前瞻性研究，纳入24例行内镜下3型鼓室成形术的患者，采用部分听骨赝复物（PORP）进行听骨链重建（OCR），并采用软骨移植进行鼓膜重建。术前及术后6个月进行听力图检查。
91.7%的病例获得了干耳、鼓膜封闭、自洁的耳朵。术前平均气骨导差（ABG）为30.4dB，术后平均ABG为16.7dB，增益为13.6dB。ABG缩小至20dB或更小的比例为79.2%，缩小至10dB或更小的比例为29.2%。
对于熟悉使用内镜进行中耳手术的外科医生来说，内镜下鼓室成形术和OCR是一种有效的选择，因为它可以在中耳重建过程中更好地观察假体和移植物的放置情况。
