Abstract:

Surgery is considered as the mainstay of therapy，but recommendations for the preferred approach and technique are quite variable. Marsupialization is less invasive，and is recommended by a number of authors as the first line choice of oral ranula，particularly in children. However，simple marsupialization has a high recurrence rate，and oral ranula was possibly transformed into plunging or cervical ranula after repeated procedures. Various surgical approaches have been used for plunging ranula，suggesting that many practitioners are unaware of an optimal technique，presumably because the etiologic basis for the disease is poorly understood. Transoral excision of the ipsilateral sublingual gland with evacuation or drainage of cyst fluid has the lowest rate of recurrence，and is expected to cure oral and plunging ranula，though it still leads to complications，such as dysaesthesia of the tongue，damage to Wharton′ s duct，bleeding，and haematoma，because of the small operative space and the complexity of structures within the floor of the mouth. This paper gives a summary of the current surgical methods of ranula and prevention of operative complications based on author′ s experience and literature review.
