A decade of experience of thyroglossal cyst excision

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

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.

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.

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.
