[Surgery of thyroglossal duct in childhood].
A retrospective review of 177 neck masses in childhood treated between January 1975 and December 1990 at the "Bambino Gesù" Pediatric Hospital of Rome is presented, with particular emphasis on recurrences and their causes. 105, object of our study, were thyroglossal duct cysts (TDC) (58.7%); in the remaining 72 cases there were dermoid cysts (23.1%), granulomas (7.9%), lateral neck masses (1.69%) and other histological patterns. The aim was to identify the variables that could change postoperative hospitalization or cause the recurrence. The TDC's group was separated in two: 92 primary patients, while 13 received a preliminary operation in other institutions. In the first group we applied 41 Sistrunk, 43 Schlange, 8 cystectomies; 5 recurrences occurred (5.43%), 3 of which in patients operated on with modified Sistrunk's technique (Schlange) (60%). In the second group (13 patients) a standard Sistrunk procedure was always performed. We had only one recurrence (7.69%) due to a remnant of multiple proximal thyroglossal duct. In 11 cases (10.47%) there were postoperative complications due to an existing inflammatory condition of the TDC (8 patients -72.72%). In only one case there was a recurrence after 27 months. Histological study of the specimens showed that thyroglossal ducts were frequently multiple and widely spaced and may also be present in the distal portion of the duct; in our series in 16.19% we found the distal portion of the duct during the operation. Our overall recurrence frequency is 5.7%. Every lesion referred to a TDC must be treated with a Sistrunk procedure for the better results achieved with this surgical approach but, in our experience, we prefer to complete the Sistrunk's technique with the research and exeresis of the distal portion of the duct by a "muscular sparing procedure" that preserves little patients from pharyngodynia. At the follow-up, we have not recurrence in the 17 cases operated on by this procedure.
