Answer

The recurrence rates of an oral ranula is variable depending on the size of the lesion and the surgical procedure performed. The rates of recurrence with various surgical treatment methods are as follows [50] :

  • Incision and drainage, 71-100%
  • Ranula excision only, 0-25%
  • Marsupialization only, 61-89%
  • Marsupialization with packing, 0-12% (limited studies)
  • Complete excision of the ranula with the sublingual gland, 0-2%

In a 2019 proportion meta-analysis, intraoral resection of the of the sublingual gland had the highest cure rate for oral ranulas (98.8%). [51] Similarly, micromarsupialization and its modifications showed a cure rate of 93.85%, but moderate inconsistencies in the cure rates were found.
