There is not an ideal tympanomeatal flap incision type for transcanal procedures. Comparing the outcomes and feasibility of posteriorly and anteriorly based tympanomeatal flap incisions for anterior perforations in endoscopic transcanal cartilage tympanoplasty. Twenty-six patients who had anterior TM perforation were included. Patients were divided into two groups with randomization. All of the data were prospectively collected. These included demographic data, date of the surgery, mean surgery time, preoperative and postoperative sixth-month pure-tone audiometry (PTA), type of tympanomeatal flap incision and graft healing success. Mean follow up time was 20.69 ± 5.03 months. Graft healing rate was 100% in both groups. There was no major complication in both of groups. Mean air bone gap level improvement of (dB HL) at all frequencies was 7.69 ± 2.83 dB HL in group 1 and 7.98 ± 3.08 dB HL in group 2 respectively. Regarding pre-and postoperative mean air bone gap levels and mean surgery times, there was no significant difference between groups (>.05). For non-complicated anterior perforations that are less than 50% of TM, endoscopic transcanal cartilage tympanoplasty using anterior tympanomeatal flap elevation procedure was seemed minimally invasive and feasible to perform with successful audiologic and postoperative outcomes.
对于经耳道手术，没有理想的鼓室鼓膜瓣切口类型。比较基于后方和前方的鼓室鼓膜瓣切口在内镜经耳道软骨鼓膜成形术中治疗前方穿孔的效果和可行性。纳入26例有前方鼓膜穿孔的患者。患者随机分为两组。所有数据均前瞻性收集。这些数据包括人口统计学数据、手术日期、平均手术时间、术前和术后六个月的纯音听力测定（PTA）、鼓室鼓膜瓣切口类型和移植物愈合成功率。平均随访时间为20.69±5.03个月。两组的移植物愈合率均为100%。两组均无严重并发症。第1组所有频率的平均气骨导差水平改善（dB HL）为7.69±2.83 dB HL，第2组为7.98±3.08 dB HL。关于术前和术后的平均气骨导差水平和平均手术时间，两组之间无显著差异（>0.05）。对于小于鼓膜50%的非复杂性前方穿孔，采用前方鼓室鼓膜瓣掀起术的内镜经耳道软骨鼓膜成形术似乎微创且可行，听力和术后效果良好。
