• Most ranulas are pseudocysts, originating from ductal injury with subsequent extravasation and accumulation of saliva in the surrounding tissue.
• Sometimes it can be a true cyst with epithelial lining, arising from ductal obstruction.
• Oral ranula
- Blue translucent swelling in the floor of the mouth
• Plunging ranula
- Cervical swelling
- Herniates through or at posterior border of the m. mylohyoideus.
|Fig. 1: Clinical presentation
Management of the ranula is controversial. There are several different options, each with advantages and disadvantages.
• Carbon dioxide laser
- Ranula excision
- Sublingual gland + ranula excision
- Sublingual gland + ranula evacuation
Recurrence and complications of ranula treatment in 35 patients.
Material and Methods

• 35 patients
- Mean: 19
- Range: 4 - 64
• Male-female ratio: 2 to 3
Infection (1), plunging ranula (1), togue hypesthesia (1)
cicatrization of Wharton's duct: excision of gl. submandibularis (1)
|Excision ranula and gl. sublingualis
postoperative bleeding (1)
|Excision gl. submandibularis
|Tab. 1: Treatment of Ranula
Excision of the ipsilateral sublingual gland with ranula excision (true cyst) or with evacuation of the ranula (pseudocyst) is first choice treatment for oral and plunging ranula
Marsupialization only in infants or patients in poor general condition
No additional excision of submandibular gland
- No causal relationship between submandibular gland and ranula
- Higher risk of injury of ramus marginalis and hypoglossal nerve with transcervical approach
