The persistently misunderstood plunging ranula

To the Editor: Possibly the reason for the plunging ranula to be persistently misunderstood is given by the statement by McGurk published in 2013 [1] that ‘a feature of the literature [about ranula] is the limited experience of most authors. [...]reports of small numbers of cases continue to be made and sometimes advise management that contradicts these extensive investigations. Furthermore, details of the optimal surgical management of plunging ranula by transoral removal of the ipsilateral sublingual gland alone followed by transoral drainage are included in a recent textbook on the surgery of the salivary glands [9], which hopefully will enable the optimal management of ranula to be widely understood, accepted and practised.Declaration of competing interest None.
