[Thyroglossal duct cyst(fistula) operation and recurrence prophylasis].

OBJECTIVE: To explore what leads to recurrent thyroglossal duct cyst (TGDC) following operation and how to improve the operation efficiency. METHOD: 32 patients with TGDC (including 8 recurrent cases) were performed operation for the second time. The cases who had infective signs received anti-inflammatory treatment prior to operation. Judge the relationship between thyroglossal duct cyst and hyoid bone before managing hyoid bone. The methylene blue was injected into TGDC for following up. Resect the small branches according to Sistruk procedure under the operation microscope. The residue underwent marsupiatization, electrocoagulation or radio frequency according to finger palpation. RESULT: 32 cases were successful with the operation and did not show any signs of recurrence after one-year following up. CONCLUSION: The recurrence of TDGC may be perfectly prevented as long as comprehensive treatment is carefully performed during the operation.
