Evaluation of preoperative cutaneous fistula as a risk factor for recurrence of thyroglossal duct cyst in children.

• The main risk factor for recurrence of TGDC is the presence of a preoperative cutaneous fistula, with an estimated hazard ratio of 4.95 (p = 0.016) in multivariate analysis. • The presence of two preoperative infections was also associated with a greater risk of recurrence in univariate analysis; age and gender were not associated with an increased risk of recurrence.
