A retrospective study was performed on patients who underwent myringoplasty for either anterior or subtotal perforations over an 8-year period (from 1994 till 2004). We used the KTP-laser assisted anterior anchoring technique combining with anterior "pull-back" method. Patients' ages ranged from 6-62 years (median 36.5). The mean follow-up period was 2.8 years (minimum 6 months). The audiological results were analysed with the "Pytel software", which was developed in our department. As for the procedure, the drum remnant was freed from the malleus handle with the use of the laser and elevated out of it's sulcus anterior-superiorly. Large fascia graft was fashioned with a split of 4-5 mm in the middle of one edge. The graft was placed using the underlay technique medial to the handle of the malleus. A pull-back tunnel was created at the border of the anterior quadrants to further facilitate the survival of the graft. In this series the graft taking rate was 100%. Reperforation due to an undersized fascia was observed in one case. Post-operative audiological results indicated no bone conduction threshold elevation in any frequencies. Using the laser, cochlear trauma can be prevented, double fixation of the drum prevents lateralisation and blunting. Wide canalplasty makes both the approach and the follow-up very easy. Thorough soft tissue and bone work is advantageous from the fascia taking rate point of view.
对1994年至2004年8年间因鼓膜前部穿孔或大部穿孔而接受鼓膜成形术的患者进行了一项回顾性研究。我们采用了KTP激光辅助前固定技术并结合前部“回拉”法。患者年龄在6至62岁之间(中位数为36.5岁)。平均随访期为2.8年(最短6个月)。使用我们科室开发的“Pytel软件”分析听力结果。至于手术过程,使用激光将鼓膜残余部分从锤骨柄上分离,并从前上方将其从沟中抬起。在一条边缘的中间制作一个4至5毫米宽的大筋膜移植物。采用衬里技术将移植物放置在锤骨柄内侧。在前象限边界处创建一个回拉通道以进一步促进移植物存活。在该系列中,移植物成活率为100%。有1例因筋膜尺寸过小而出现再穿孔。术后听力结果表明,任何频率下骨导阈值均未升高。使用激光可防止耳蜗损伤,鼓膜的双重固定可防止侧移和变钝。宽耳道成形术使手术入路和随访都非常容易。从筋膜成活率的角度来看,彻底的软组织和骨组织处理是有利的。
