갑상설관낭종의 염증과 수술적 치료 성적사이의 상관 관계

Background and Objectives: Thyroglossal duct cysts (TGDC) are the most common developmental head and neck lesion in children and adolescents and often presents as infected neck mass. The purpose of this study is to determine if preoperative infection was related to complication, including postoperative infection and recurrence. Materials and Methods: The medical records of all the patients with the diagnosis of TGDC treated at our department from January 1995 to July 2006 were reviewed and retrospectively analyzed. Data collected included age, sex, preoperative inflammation, treatment, postoperative inflammation and recurrence. Results: One hundred twenty-five (125) patients with histologically confirmed TGDC were treated at our department. The mean age at operation 22.3 ± 19.0 years (range, 8 months -70 years). Male to female ratio was 1.3:1. TGDC recurred in 8% (10 of 125 patients). All patients underwent a Sistrunk operation. There was no gender difference for those with and without recurrence (p=0.666). The presence of an abscess or cellulitis preoperatively did not correlate with recurrence (p=0.457). Postoperative infection occurred in 14 of 125 patients and also was independent of preoperative infection (p=0.077). However, postoperative infection was associated with an increase risk of TGDC recurrence. one of 115 patients without recurrence had a postoperative infection, whereas 9 of 10 those who had a recurrence had a postoperative infection (p<0.001). The mean followup was 2.6 years. Ten patients successfully underwent a second procedure for recurrence. Conclusions: Preo-perative infection occurred in approximately in 1 of 5 patients and was not predictive of recurrence. Although postoperative infection did not correlate with the presence of preoperative infection, it was clearly associated with a statistically significant incidence of recurrent disease.
