Diagnosis and treatment of congenital submandibular duct dilatation

: 目的 探讨先天性颌下腺导管扩张症的临床特点及治疗方法。方法 2008年1月—2018年3月共收治7例先天性颌下腺导管扩张患儿，平均年龄5月22天；临床上表现为单侧的口底膨隆肿胀。7例患儿均在全麻下行患侧舌下腺腺体切除、颌下腺扩张部分导管切除及导管改道术，术中可见颌下腺导管口狭窄，部分导管呈扩张状态。结果 7例患者术后口底创口均愈合良好，无肿胀及囊肿发生。结论 先天性颌下腺导管扩张症患儿的发生年龄小，早期诊断与治疗有助于防止导管扩张加重，避免腺体萎缩、喂养困难以及阻塞呼吸；舌下腺腺体的同期切除可以避免术后舌下腺囊肿的发生。. METHODS: Seven children with congenital submandibular duct dilatation from January 2008 to March 2018 were included in this study, whose average age was 5 months and 22 days. The clinical manifestations are unilateral swelling of the mouth floor. All seven children underwent sublingual gland resection, submandibular gland dilatation catheter resection, and catheter reroute under general anesthesia. Intraoperatively, the orifice of the submandibular gland was constricted and part of the catheter was dilated. RESULTS: All seven patients had good healing without swelling or cyst formation. CONCLUSIONS: Congenital submandibular duct dilatation occurs at a young age. Early diagnosis and treatment can help prevent further expansion of the catheter and avoid gland atrophy, feeding difficulty, and breathing obstruction. Simultaneous excision of the sublingual gland can avoid the formation of postoperative sublingual cyst.
