Abstract
INTRODUCTION
Lingual thyroglossal duct cysts (LTGDC) are a rare kind of thyroglossal duct cyst. However, Sistrunk surgery is not very suitable for this type of cyst. This study aimed to explore the efficacy of transoral excision of LTGDC by plasma coblation.
METHODS
The present study reviewed 11 patients, comprising seven males and four females, who had been diagnosed with LTGDC preoperatively by computed tomography (CT) and fibre-optic electronic laryngoscopy. Of those patients, two had recurrence after surgery of epiglottic cysts. All these patients underwent transoral excision by plasma coblation. Then, we collected preoperative data of the patients, observed the effect of surgery, and analysed factors relevant to LTGDC, including the estimated bleeding amount, postoperative hospitalisation, complications and recurrence rates.
RESULTS
The connection between LTGDC and hyoid was tapered on sagittal images of CT, which was vital evidence for the diagnosis of LTGDC. Surgery was performed successfully for all 11 patients, and all recovered without complication. There was no evidence of recurrence after surgery, during follow up for 3-43 months.
CONCLUSIONS
Transoral surgery for LTGDC can be performed successfully by plasma coblation, which is an effective and safe surgical treatment. Fibre-optic electronic laryngoscopy and CT are essential to the diagnosis of LTGDC in order to avoid missing detection and misdiagnosis.
