A decade of experience of thyroglossal cyst excision.

Introduction: We report our ten-year experience of thyroglossal cyst excision at Queen's Medical Centre, Nottingham, comparing outcomes, practice and technique.

Methods: Retrospective case note analysis was conducted alongside surgical histopathology review for all thyroglossal cyst excisions performed between 2000 and 2010. This yielded 108 patients with histopathology results confirming a thyroglossal cyst.

Results: The mean patient age was 21 years (range: 1 week - 76 years). Over half the patients (n=59, 55%) were less than 18 years of age. Fifty-five patients (51%) were male and fifty-three (49%) were female. Seventy cases (63%) were operated on by ear, nose and throat (ENT) surgeons. The rest were performed by paediatric surgeons (n=35, 32%), maxillofacial surgeons (n=2, 2%) and general surgeons (n=1, 1%). Paediatric surgeons undertook 35 (69%) of the 59 paediatric cases, with ENT surgeons operating on the rest (n=24, 41%). The primary surgeon was a consultant in 59 operations (55%) while in 49 cases (45%) it was a registrar. Thyroglossal cysts were ruptured in 21 operations (19%) during removal. The central portion of the hyoid bone was not excised in seven cases (6%). Twelve patients (11%) suffered postoperative complications, six of which were recurrences.

Conclusions: There was a combined recurrence rate of 6% across all specialties for the Sistrunk procedure. This is in keeping with commonly reported recurrence rates. However, we found that central compartment neck dissection, as a modification of the original Sistrunk procedure, provides a highly effective method for permanently excising a thyroglossal cyst and, in our experience, it eliminates recurrence.
