Objective:To investigate the effect of low-temperature plasma obliteration for pyriform sinus fistula by visual laryngoscope. Methods:The clinical data of 29 cases with congenital pyriform sinus fistula receiving low temperature plasma obliteration by visual laryngoscope during March 2019 to August 2021 was retrospectively analyzed in department of Otolaryngology Head and Neck Surgery of Children's Hospital of Nanjing Medical University. Nineteen cases accepted the pyriform sinus fistula probing + fistula obliteration, 6 cases accepted the pyriform sinus fistula probing + fistula obliteration + neck abscess incision and drainage, and 4 cases with cervical abscess accepted the pyriform sinus fistula probing + fistula obliteration. Results:All cases had no obvious complications. Two cases had vocal cord impairment after operations and recovered after one month. There was no recurrence in 2 to 30 months follow up, with mean 16 months follow up. Conclusion:Low-temperature plasma obliteration of pyriform sinus fistula by visual laryngoscope is a safe and effective surgical method with little trauma and short hospital stay. It could be the first choice for the treatment of pyriform sinus fistula. Incision and drainage of neck abscess and pyriform sinus fistula obliteration could be performed concurrently.
目的：探讨可视喉镜下梨状窝瘘内口低温等离子封闭术的手术效果。 方法：回顾性分析2019年3月—2021年8月在南京医科大学附属儿童医院耳鼻咽喉头颈外科行可视喉镜下梨状窝瘘内口低温等离子封闭术的29例先天性梨状窝瘘患儿的临床资料。19例行梨状窝瘘探查+瘘口封闭术，6例行梨状窝瘘探查+瘘口封闭术+颈部脓肿切开引流，4例颈部质硬包块者行梨状窝瘘探查+瘘口封闭术。术后均留置胃管。 结果：所有患儿术后无严重并发症，2例出现术后声嘶，1个月后自行恢复。随访2~30个月，平均16个月，均无复发。 结论：可视喉镜下梨状窝瘘内口低温等离子封闭术是一种安全有效的手术方式，创伤小，住院时间短，可作为治疗梨状窝瘘的首选术式，颈部脓肿切开引流和内口封闭可同时进行。.
