Congenital cyst at the base of the tongue was encountered in 7 infants. The histopathological examination on the cystic tumors revealed the cystic wall composed of a stratified layer of the epithelium without proliferation of connective tissue and with no noticeable lymphoid cell infiltration.<BR>This suggested thatcy stic tumors originate from the thyroglossal duct. A lateral view of the X-ray film of the pharynx was simple but very useful for its diagnosis. Furthermore, this procedure was useful for postoperative observation. Total resection of the outer part of the cystic wall was performed by laryngo-microsurgery in all cases.<BR>Successful results were confirmed by follow-up study. This method of operation can be carried out safely and easily. It may provide a favorable postoperative state without recurrence.
