耳内镜下鼓膜大穿孔鼓室成形术及其临床疗效分析

【目的】分析耳内镜下鼓膜大穿孔鼓室成形术的临床疗效。【方法】回顾性分析我科2017年5月至2019年1月间因慢性化脓性中耳炎鼓膜大穿孔行鼓室成形术的110例（115耳）患者，术中清理鼓室病变及重建听骨链，使用耳屏软骨-软骨膜复合体修补鼓膜，并对术前评估为咽鼓管功能不良的患者同期进行咽鼓管球囊扩张术。观察术后鼓膜一期愈合情况及术后3个月时的言语频率平均气导听阈（PTA）及气骨导差（ABG）。【结果】110例（115耳）患者术后鼓膜一期愈合率为95.7%，术后3月时PTA和ABG分别为（25.7±11.8）dBHL和（13.8±6.9）dBHL，与术前相比，PTA明显降低，ABG明显缩小（均P<0.001）。对于咽鼓管功能不良的患者同期行鼓室成形术和咽鼓管球囊扩张术（共29耳），与单纯鼓室成形术的患者（共86耳）相比，鼓膜愈合率、PTA和ABG无统计学差异（P>0.05）。【结论】耳内镜下鼓室成形术临床疗效可靠，耳屏软骨-软骨膜复合体是鼓膜大穿孔鼓室成形术可靠的修复材料，值得临床上推广应用。对于咽鼓管功能不良的患者，同期行咽鼓管球囊扩张术可取得良好的临床疗效。

Clinical Efficacy of Endoscopic Tympanoplasty for Large Tympanic Membrane Perforation

【Objective】To investigate the clinical efficacy of endoscopic tympanoplasty for chronic suppurative otitis with large tympanic membrane perforation.【Methods】A total of 110 cases（115 ears）which were diagnosed as chronic suppurative otitis with large tympanic membrane perforation were retrospectively collected from May 2017 to Jan 2019. All cases were performed endoscopic tympanoplasty；including removing tympanic lesions，reconstruction of ossicular chain， and myringoplasty with cartilage and perichondrium complex by underlay technique. At the same time of tympanoplasty ， balloon eustachian tuboplasty（BET）was performed in patients who were diagnosed with eustachian tube dysfunction. The graft success rate，pure tone threshold average（PTA）of speech frequency and the air-bone gap（ABG）were assessed at 3 months after surgery.【Results】The primary graft success rate was 95.7%，and the PTA and ABG were（25.7±11.8）dB HL and（13.8 ± 6.9）dB HL，respectively，which showed significant differences compared with pre- operation conditions （P < 0.001）. Furthermore，29 ears which were diagnosed with eustachian tube dysfunction were treated with BET at the same time of tympanoplasty. Compared with simply tympanoplasty （86 ears），no difference was found in primary graft success rate ，PTA and ABG post-operation（P > 0.05）.【Conclusions】 Endoscopic tympanoplasty is an effective surgery，and the cartilage and perichondrium complex is a reliable repair material for large tympanic membrane perforation ，which are both worthy of clinical promotion. Furthermore ，BET at the same time of tympanoplasty could ensure clinical efficacy for the patients with eustachian tube dysfunction.
