The authors reviewed clinically 164 cases of congenital neck cyst, histologically proven from Janury 1980 to June 1992 at the Department of Surgery of the Presbyterian medical center, among 2048 cases of head and neck masses in the same period.
@ES The olowing results were obtained;
@EN 1) Of the 164 cases, Age of two patients were less than one month and 35 patient were more than 30 years-old.
2) The largest proportion of congenital neck cyst was thyroglossal duct cyst, comprising 52.4% of all cases. Following these in order of frequency were cystic hygroma (23.8%), and branchial cleft cyst(22.5).
3) In the case of congenital neck cyst, male to female ratio was 1.2 : 1.
4) The lesions were analyzed by anatomical presentation and by bilaterality as an aid to diagnosis. Lesions which were unilateral cystic hygroma were in the 89.7% of cases and were branchial cleft cyst in all of cases. Central cystic lesions
were
most
commonly thyroglossal duct cyst (84.9%).
5) Analysis by operative finding of the masses reveles that cysts were most common in 92% of the cases, and sinuses 5.3%, fistula 4.7%.
6) In terms of treatment guidelines, complelte excistion was considered adequte treatment modality. 96.3% of the patients received complete excision. In the thyroglossal duct cyst, susscesful operation requires removal of the cyst, its entire
and
the
central compartent of hyoid bone. In the cystic hygroma, when complelte excision is not possible, the lesion should be unroofed and well drained with the expectation that recurrence and further surgical excision may be required in the future.
