Objective:To explore the clinical value of recurrent laryngeal nerve dissection in the surgical treatment for congenital pyriform sinus fistula（CPSF）. Methods:The clinical data of 42 patients with CPSF were retrospectively analyzed. All patients were diagnosed and treated in the First Affiliated Hospital of Guangdong Pharmaceutical University. Results:During the operation, all patients' recurrent laryngeal nerves were dissected successfully, and fistulas were resected completely,no patients had complication of recurrent laryngeal nerve's damage.There were no recurrence cases during the 13 to 48 months of follow-up. Conclusion:The trend of congenital pyriform sinus fistula is closely related to recurrent laryngeal nerve, it's important to dissect the recurrent laryngeal nerve during the operation for congenital pyriform sinus fistula.
目的：探讨喉返神经解剖在颈部开放性手术切除先天性梨状窝瘘（congenital pyriform sinus fistula，CPSF）的临床意义。 方法：回顾性分析广东药科大学附属第一医院2016年4月—2019年12月间行颈部开放手术切除42例CPSF患者的临床资料。 结果：所有患者术中均进行喉返神经全段解剖，将瘘管完整分离及切除，术后无喉返神经损伤并发症，随访期内无复发病例。 结论：CPSF瘘管走行与喉返神经关系密切，在术中先行喉返神经解剖可避免损伤，减少并发症。.
