A Comparison of Endoscopic and Microscopic Tympanoplasty Type 1 in a Developing Country: How We Do It
摘要
To compare success rate and quality-of life parameters of endoscopic and microscopic tympanoplasty. Retrospective comparative study. After written informed consent, patients aged 10–55 years with Chronic otitis Media inactive mucosal disease, unilateral/bilateral, having dry large central/subtotal perforation, underwent Tympanoplasty type I under local anesthesia via transcanal approach using 00 endoscope with temporalis fascia graft harvested from a supratemporal incision (Group A), conventional microscopic tympanoplasty via postaural approach (Group B). Technique used was circumferential subannular underlay tympanoplasty. VAS was used to record postoperative pain at 24 h, 7 days, and overall patient satisfaction at 12 months. In Group A 89/98 (90.8%) and in Group B 86/97 patients (88.7%) had successful graft uptake (p = 0.62, NS). Average air-bone gap closure was 17.4 +- 3.88 dB & 16.8 +- 3.46 dB (P = 0.256, NS). VAS scores for pain at 24 h were 0.63 and 2.55 (p = 0.001, S), 7 days postoperatively were 0.21 & 1.09 (p = 0.001, S). VAS Scores for overall procedural satisfaction at 12 months were 8.04 &7.84 (p = 0.227, NS). Average operating time was 34.3 and 47.9 min (p = 0.001, S). Endoscopic tympanoplasty is faster, less painful and better overall patient satisfaction, hence better quality of life compared to conventional microscopic tympanoplasty.
