作者报告了近年收治的１２例儿童梨状窝瘘的诊断与处理经验。患者年龄为１．５～１０岁。１１例表现为左侧颈部炎性肿块，发作期颈部超声检查及核素显像示炎症累及甲状腺左叶，炎症消退后作食管吞钡造影，均证实存在左侧梨状窝瘘；１例为左侧甲状腺无痛性囊性肿块。６例行手术治疗，其中４例予瘘管高位结扎切除；１例术中未能找到瘘管，术后吞钡复查，瘘管消失；１例甲状腺左叶无痛性囊性肿者，术中证实梨状窝瘘伴甲状腺内囊肿形成，行囊肿切除及瘘管高位结扎术。患者术后均恢复良好，随访１～５年无复发。另６例未手术者，５例１～６年无症状，１例２年间有３次发作。作者认为，充分认识梨状窝瘘，对于化脓性甲状腺炎或原因不明的颈部感染的处理具有重要意义。
