Chronic Otitis Media (COM) is a major cause of acquired hearing impairment especially in developing countries. Persistent perforations occur either due to improper treatment of recurrent otitis media or infected traumatic perforation. Myringoplasty, repair of the Tympanic membrane using autologous temporalis fascia, is the standard procedure for COM. Other graft materials commonly used include tragal perichondrium, tragal cartilage and adipose tissue. This prospective study aims to compare the surgical and audiological outcome of fat plug myringoplasty [FPM] and conventional myringoplasty using temporalis fascia [CM-TF] in COM with small dry central perforation. A total of 60 patients of COM with small dry central perforation, aged 16-60 years, during the study period of October 2013 to August 2015 were divided into two groups of 30 cases each. The first group underwent FPM while the second group underwent CM-TF. The graft uptake and hearing outcome [pre operative and 3 months post operative PTA] were assessed. The surgical outcome of FPM with graft uptake of 86.7% was comparable to CM-TF with a graft uptake of 90%. The mean post operative hearing gain in FPM was 3.43 ± 2.81 dB which correlated well with that of CM-TF with 3.85 ± 3.05 dB. The duration of hospital stay and operative time was significantly lower in FPM group. FPM can be safely performed in cases with dry, small central perforations of the tympanic membrane with outcomes comparable to CM-TF.
慢性中耳炎(COM)是后天性听力障碍的主要原因,尤其是在发展中国家。持续性穿孔要么是由于复发性中耳炎治疗不当,要么是感染性外伤性穿孔所致。鼓膜成形术,即使用自体颞肌筋膜修复鼓膜,是治疗慢性中耳炎的标准手术。其他常用的移植材料包括耳屏软骨膜、耳屏软骨和脂肪组织。本前瞻性研究旨在比较脂肪栓鼓膜成形术[FPM]和使用颞肌筋膜的传统鼓膜成形术[CM-TF]在鼓膜干性中央小穿孔的慢性中耳炎患者中的手术和听力结果。在2013年10月至2015年8月的研究期间,共有60例年龄在16 - 60岁的鼓膜干性中央小穿孔慢性中耳炎患者被分为两组,每组30例。第一组接受脂肪栓鼓膜成形术,第二组接受使用颞肌筋膜的传统鼓膜成形术。评估了移植物的吸收率和听力结果(术前和术后3个月的纯音听阈平均值)。脂肪栓鼓膜成形术的移植物吸收率为86.7%,与移植物吸收率为90%的使用颞肌筋膜的传统鼓膜成形术相当。脂肪栓鼓膜成形术术后平均听力增益为3.43±2.81dB,与使用颞肌筋膜的传统鼓膜成形术的3.85±3.05dB相关性良好。脂肪栓鼓膜成形术组的住院时间和手术时间明显更短。对于鼓膜干性中央小穿孔的病例,脂肪栓鼓膜成形术可以安全实施,其结果与使用颞肌筋膜的传统鼓膜成形术相当。
