Recurrent plunging ranula of the neck

Abstract

The reported case describes a mismanaged extensive recurrent plunging ranula that occupied a large portion of the neck. The ranula is usually clinically diagnosed. However, absence of visible intra-oral signs may mislead the diagnosis and leads to improper surgical management. Presence of amylase in the aspirated fluids is an important aid in the differential diagnosis. Thereby confirming the salivary origin of the fluids and thus avoiding extensive investigations. The recurrence rate varies according to the procedure performed. Diverse methods of treating ranula have been reported in the literature with variable results. These include marsuplization, excision of the ranula, incision of the ranula and drainage of the contents, excision of the sublingual gland and drainage. The successful procedure to treat plunging ranula depends on complete excision of the affected sublingual gland and drainage of its contents. In this paper, the useful diagnostic investigations and the recommended surgical intervention procedure were described.
