Objective: To describe a method of hyoid cartilage division during Sistrunk operation for management of thyroglossal duct cyst (TGDC) and compare postoperative outcomes with those of conventional hyoid bone cutting.
Methods: Fifty-nine patients who received operative treatment for TGDC from January 2005 to July 2013 were enrolled. The degree of fusion in the cartilaginous portion of the hyoid was evaluated by preoperative neck computed tomography and classified into (1) non-fusion, (2) partial fusion, and (3) complete fusion. Techniques of hyoid management, division of the cartilaginous portion of the hyoid or conventional hyoid bone cutting, during Sistrunk operation were analyzed according to the fusion classification.
Results: Of the 59 patients, 27 were pediatric patients and 32 were adults. In 32 adults undergoing TGDC, there were 13 cases (41%) of complete hyoid fusion and 7(22%) of non-fusion. A total of 20 adult patients (63%) were treated with the cartilage division. Among the pediatric patients, 96% of cases were classified as non-fusion of the hyoid, and all of these were treated with the cartilage division. Patients who were treated with the cartilage division showed better postoperative results. However, there were no statistical differences.
Conclusions: Our cartilage division technique at Sistrunk operation for TGDC is feasible and comparable to conventional hyoid cutting with regard to postoperative results.
