Regarding ranula, all are true except

RANULA It is a cystic translucent lesion seen in the floor of the mouth on one side of the frenulum and pushing the tongue up. It arises from the sublingual salivary gland due to obstruction of its ducts. Some ranulae extend into the neck. Treatment It involves complete surgical excision if small or marsupialization if large. Often it is not possible to excise the ranula completely because of its thin wall or ramifications in various tissue planes. (Ref: Textbook of ENT, PL Dhingra, 7th edition, pg no. 252)
