This study aimed to evaluate the surgical success of a modified inlay tympanoplasty technique, known as circumferential subannular tympanoplasty, for anterior and subtotal perforations.
This prospective study was performed in a tertiary care teaching hospital between October 2013 and April 2016. A total of 58 adult patients of both sexes with anterior or subtotal perforations underwent circumferential subannular tympanoplasty under local anaesthesia. In this technique, after tympanomeatal flap elevation, the temporalis fascia graft is placed directly onto the annulus instead of being tucked underneath the tympanic membrane remnant. Outcome data were graft uptake and hearing improvement.
This technique had a surgical success rate of 97 per cent and led to significant hearing improvement.
Circumferential subannular tympanoplasty has a definitive role in managing anterior and subtotal perforations.
本研究旨在评估一种改良的内嵌式鼓室成形术技术，即环周鼓膜下鼓室成形术，用于治疗前部和大部分穿孔的手术成功率。
本前瞻性研究于2013年10月至2016年4月在一家三级医疗教学医院进行。共有58例患有前部或大部分穿孔的成年男女患者在局部麻醉下接受了环周鼓膜下鼓室成形术。在该技术中，掀起鼓室耳道皮瓣后，颞肌筋膜移植物直接放置在鼓环上，而不是塞在鼓膜残余物下方。结果数据为移植物吸收情况和听力改善情况。
该技术的手术成功率为97%，并带来了显著的听力改善。
环周鼓膜下鼓室成形术在治疗前部和大部分穿孔方面具有明确作用。
