Abstract

We report 6 cases of thyroglossal duct cysts in children, treated at our clinic from 1979 to 1994 and we did clinical studies of them.<BR>Results were as follows:<BR>1) In 6 cases, 4 males and 2 females, the thyroglossal duct cysts appeared between 5 nonths and 10.7 years old (mean age was 3.6 years old). One of them was a recurrence case.<BR>2) The lesions, have no pain, being found in the midline neck region at or upon the level of the hyoid bone, and the measurements of the lesions were from 10 to 30 mm in diameter.<BR>3) Imaginary diagnosis for MRI is very useful to get the information about the location, volume, expanse and so on, of the lesion.<BR>4) Two cases were operated cystectomy with partial resection of the hyoid bone because of adhesion between the cyst and the hyoid bone, four cases were operated cystectomy or fistulectomy without resection of the hyoid bone, of which one had recurrence but has been well for 10 years since reoperation.<BR>5) Histopathologically, the epitherium lining of the cysts were stratified squamous epithelium in 4 cases, ciliated columner in 2 cases. There are accessory organs in the cyst wall, such as mucous glands (lcase), thyroid tissue (lcase).
