To evaluate effectiveness of endoscopic tragus cartilage-perichondrium in the treatment of large tympanic membrane perforations.
Patients with large tympanic membrane perfortations who had underwent cartilage-perichondrium myringoplasty were retrospectively retrieved from our department. Those with a follow-up of equal to or greater than 12 months after surgery were included in the study. Hearing test results were reported using a four-frequency air conduction and bone-air conduction gap. Patients were labeled as treatment success if the tympanic membrane was intact without lateralization or anterior blunting after surgery.
Of the 35 patients with large tympanic membrane perforations treated by endoscopic tragus cartilage-perichondrium, 33 (94.3%) were treatment success. There was no graft lateralization, anterior blunting, neocholesteatoma, and sensorineural hearing loss in these patients after surgery. The air conduction and bone-air conduction gap before surgery in the study cohort were (43.8 ± 5.7) dB and (28.5 ± 3.1) dB, respectively. Postoperative air conduction and bone-air conduction gap of the cohort were (31.4 ± 6.4) dB HL and (16.2 ± 4.1) dB, respectively. The postoperative air conduction and bone-air conduction gap decreased significantly after surgery (P < 0.01). Overall postoperative air-bone gap in 27 of the 35 patients (77%) were less than 20 dB after surgery.
Endoscopic cartilage-perichondrium myringoplasty is an effective procedure in the treatment of large tympanic membrane perforations.
评估内镜下耳屏软骨-软骨膜在治疗大鼓膜穿孔中的有效性。
回顾性选取本科室行软骨-软骨膜鼓膜成形术的大鼓膜穿孔患者。纳入术后随访时间等于或大于12个月的患者。听力测试结果采用四频率气导和骨导气导差进行报告。如果术后鼓膜完整且无内陷或前钝，则将患者标记为治疗成功。
35例接受内镜下耳屏软骨-软骨膜治疗的大鼓膜穿孔患者中，33例（94.3%）治疗成功。这些患者术后无移植物内陷、前钝、新胆脂瘤形成及感音神经性听力损失。研究队列术前气导和骨导气导差分别为（43.8±5.7）dB和（28.5±3.1）dB。队列术后气导和骨导气导差分别为（31.4±6.4）dB HL和（16.2±4.1）dB。术后气导和骨导气导差较术前显著降低（P<0.01）。35例患者中有27例（77%）术后总体气骨差小于20 dB。
内镜下软骨-软骨膜鼓膜成形术是治疗大鼓膜穿孔的有效方法。
