-
A small, soft, fluctuating, and semi-transparent tumour, which forms under the tongue, owing to the accumulation of saliva in Wharton's duct. In order to give exit to the accumulated fluid, and to establish a permanent opening for the discharge of the saliva, the cyst may be punctured, and the opening maintained by a minute cylinder, with a button at each extremity, as has been recommended by Dupuytren; or a portion of the cyst may be removed by the scissors, and the mouth be frequently washed by any astringent lotion. Sometimes, the salivary duct is found plugged by a small calculus.
