Aim of study includes review on supra-auricular approach and its clearance of the tract including its branches and also its efficacy in reduction of recurrence when compared to standard technique. Prospective study in which 10 patients attending ENT opd with clinically diagnosed preauricular sinus undergoing supra-auricular approach under GA/LA, willing to participate in study were selected. An elliptical incision of the standard technique extended higher upward to pre- and supra-auricular temporal region. Plane of temporalis fascia was delineated. Skin, anterior to the sinus and tragus was separated. Soft tissue between the plane of temporalis fascia (deep limit) and the skin anterior to the sinus excised along with the piece of adjoining helical cartilage. This excised tissue contains the entire tract with its possible branches giving no room for recurrence. Patients were followed up for 6 months. 10 patient's data was updated and analyzed. No recurrence observed in all 10 patients. Supra auricular approach is useful and helpful technique for preauricular sinus tract excision with no recurrence rate. However further studies are required with large sample size.
研究目的包括回顾耳上入路及其对窦道(包括其分支)的清除情况,以及与标准技术相比,其在降低复发率方面的疗效。选取了10例在耳鼻喉科门诊临床诊断为耳前瘘管的患者,这些患者愿意参与研究,在全身麻醉/局部麻醉下接受耳上入路手术。标准技术的椭圆形切口向上延伸至耳前和颞区上方。确定颞肌筋膜平面。分离窦道前方和耳屏前方的皮肤。沿着相邻的螺旋状软骨块,切除颞肌筋膜平面(深部界限)与窦道前方皮肤之间的软组织。切除的组织包含整个窦道及其可能的分支,没有复发的空间。对患者进行了6个月的随访。更新并分析了10例患者的数据。所有10例患者均未观察到复发。耳上入路是一种用于耳前窦道切除的有用且有效的技术,无复发率。然而,需要进一步进行大样本量的研究。
