[Experience of diagnosis and treatment of lingual thyroglossal duct cyst]

Objective: To explore and analyse the imaging examinations, clinical presentation, operative methods complication and the surgical outcomes of lingual thyroglossal duct cyst (LTGDC) . Methods: The clinical data of 30 patients with LTGDC were analyzed retrospectively from January 2015 to October 2018 at the First Affiliated Hospital of Zhengzhou University. Results: 30 cases were treated with endoscopic coblation cauterization firstly. Follow-up for 7.5-45.0(25.4) months showed that 25 cases had no recurrence, 2 cases had no connection, 2 cases had recurrence once, and 1 cases had recurrence twice,the recurrence rate was 10.7%(3/28).Two patients recurred once, and the last operation was performed with endoscopic coblation cauterization, and no recurrence was found in the follow-up of 1 year; one patient recurred twice underwent the last operation with Sistrunk operation, and no recurrence was found in the follow-up of 1 year. There was no pharyngeal fistula and hoarseness in 28 patients. Conclusions: For LTGDC,especially, those of the first-episode children, endoscopic coblation cauterization is the first choice. Recurrent LTGDC can be treated by endoscopic coblation cauterization, so that patients with multiple recurrences can be considered the Sistrunk operation.
