Thyroglossal duct cysts: evaluation and treatment of 49 cases. Objective: The aim of the study was to evalua- te the clinical features and treatment outcomes of patients with a thyroglossal duct cyst (TGDC) or fistula. Methods: The records of 49 patients (9 female, 40 male; mean age: 23.16±1.13 years; range 6 to 56 years) operated on between January 1995 and July 2009 were reviewed retrospectively. Patients age, sex, duration of symptoms, clinical features, pre-operative diagnostic tests, treatment, histopathologic diagnosis, and post-operative complications were noted. All patients underwent the Sistrunk procedure. Results: Fifteen patients (30.6%) were 20 years old, while 3 (6.1%) patients were 40 years old at the time of opera- tion. There was cyst formation in 26 patients (53.1%) and fistula formation in 23 patients (46.9%). The lesions of 41 patients (83.7%) were located in the midline, while the lesions of 8 patients (16.3%) were located in the paramedian neck (5 left side, 3 right side). The most common presenting symptoms were painless mass in the midline of the neck and recurrent suppuration of fistula formation. Neck ultrasonography (USG) was the most common pre-operative diagnostic procedure and was performed on all patients with cyst formations. There were no major complications post- operatively. There was recurrence in only one patient after the Sistrunk procedure. One patient was incidentally diagno- sed with thyroid papillary carcinoma after histopathological examination. Conclusions: ATGDC is the most common congenital mass in the neck and is usually located midline. USG is suggested for a clinically suspected TGDC. The Sistrunk procedure is a safe and successful technique with low complication and recurrence rates. Even though carcinomas arising in TGDCs are uncommon, histopathological examination must be routinely performed to confirm the diagnosis and rule out malignancy.
