Application of “|” Shaped Incision in Concha Plasty
-
摘要:
目的 探讨“|”形切口在耳甲腔成形术的疗效。 方法 将68例慢性化脓中耳炎、中耳胆脂瘤患者随机分为“|”形切口组39例和“Y”形切口组29例，比较两组的疗效。 结果 术后随访1 a，两组病例在术后眩晕、耳鸣、术腔肉芽发生率、术腔痂皮发生率，差异无统计学意义（P > 0.05）。但术后干耳时间、上皮化时间、术后耳廓软骨膜炎，差异具有统计学意义（ P < 0.05）。 结论 “|”形切口耳甲腔成形术较“Y”形切口耳甲腔成形术在手术操作方面更简单易行，提高了手术疗效，值得推广应用。 Abstract:Objective To investigate the effect of "|" shaped incision on concha plasty. Methods 68 cases with chronic suppurative otitis media and middle ear cholesteatoma were randomly divided into two groups, with 39 cases in the "|" shaped incision group and 29 cases in the "Y" shaped incision group. Results The patients were followed up for 1 year. There was no significant difference in the incidence of postoperative vertigo, tinnitus, granulation and scab in the operation cavity between the two groups （all P > 0.05）. But there were statistically significant differences in dry ear time, epithelialization time and postoperative auricular perichondritis （ P < 0.05）. Conclusion Compared with Y-shaped incision, concha plasty with "|" incision is more simple and easy to operate, which improves the curative effect of operation, and is worthy of promotion and application. -
