Impact of age on surgical outcomes and failure rates in patients with thyroglossal duct cysts.

PURPOSE: Thyroglossal duct cyst (TGDC) may appear in all age groups. The impact of age on surgical outcome has been reported with conflicting results. The aim of the study was to evaluate different risk factors for surgical success according to stratified age groups.

METHODS: A single center retrospective study. All patients who underwent a Sistrunk procedure between 2004 and 2018 were enrolled. Data included demographics, pre-operative presentation, intra\postoperative complications and surgical failures. Population groups were divided into adults (≥18 years), older children (OC, 3-18 years) and toddlers (<3 years).

RESULTS: A total of 109 patients were included: 55 adults (50.5%), 36 OC (33%) and 18 toddlers (16.5%). The adult group demonstrated a significant lower rate of surgical failures when compared to the toddler (3.6%, vs. 38.9%, P < 0.001, respectively) and the OC group (3.6%, vs 16.7%, P = 0.032, respectively). A borderline significance was found when comparing surgical failure rates among toddlers and OC (38.9% vs.16.7%, P = 0.07, respectively). Post-operative complications were associated with surgical failures among toddlers (P = 0.045) and OC (P = 0.016), but not adults. Pre-operative infection and admission were significantly associated with failure in the OC group.

CONCLUSIONS: Surgical failures following Sistrunk procedures and their associated risk factors vary between age groups. Familiarity with these rates and associations can contribute to better decision making in managing TGDC patients.
