GROUND: Evaluation of thyroglossal duct cysts before surgical excision traditionally includes hormonal evaluation, ultrasound of the neck, and thyroid scanning. OBJECTIVE: To evaluate the need for thyroid scanning in cases of thyroglossal duct cysts scheduled for operation. METHODS: A retrospective chart review of 100 cases of thyroglossal duct cyst between 1988 and 1995 was carried out. RESULTS: No cases of ectopic thyroid were detected. CONCLUSION: Our goal was to document the presence of normal thyroid tissue by non-invasive tools such as ultrasound, rather than to rule out the existence of ectopic thyroid tissue by radionuclide scanning. Radionuclide scanning is justified in cases of lingual thyroid and where a normally located thyroid gland cannot be detected.
