Thyroglossal duct cyst’s inflammation. When do we operate?

Abstract

Thyroglossal duct cyst (TGDC) disease, one of the most common developmental neck lesion in the pediatric population, often presents as infected neck mass. The authors reviewed their experience in the management of inflamed TGDC cases, in order to suggest the most efficient approach of these patients regarding the ideal type and time of surgical intervention. The medical records of all the patients with the diagnosis of TGDC treated at our department from 1988 to 2003 were reviewed. Data collected included age, gender, preoperative inflammation, treatment and time of definitive surgery. The outcome of the operation was graded as successful, recurrence, or postoperative infection. Eighty-nine (89) patients with histologically confirmed TGDC were treated at our department. Mean age at operation was 6.0 years (range, 9 months-14 years). Male to female ratio was 1.2:1. All patients underwent Sistrunk operation and the mean follow-up was 3 years. Fifty-four (54) patients (60.6%) presented with an inflamed TGDC. Among them, 24 patients were operated immediately after diagnosis at the phase of acute inflammation, and 30 patients after antibiotic administration and resolution of inflammation. The overall recurrence incidence was 6.7%. Recurrence was noted in 6 of 24 (25%) patients operated during the acute phase of inflammation and none in patients operated after resolution of inflammation (P = 0.0052) or with no preoperative inflammation (P = 0.0002). Postoperative wound infection was noted in seven cases but none of them developed recurrence of the disease. The presence of inflammation at the time of surgery is an important risk factor for relapse. We suggest that in the inflamed cases of TGDC disease, the initial treatment should be antibiotic administration and after resolution of the inflammation, surgical management should follow.
