Ranulas are typically caused by the obstruction of salivary glands under the tongue. This obstruction leads to the accumulation of saliva, forming a cyst. Common causes of obstruction include trauma, infection, or stones in the salivary gland ducts.

Ranula

A ranula is a type of mucocele found on the floor of the mouth. It is a swelling that occurs due to the accumulation of saliva from a ruptured salivary gland duct, typically the sublingual gland. The term "ranula" is derived from the Latin word "rana," meaning "frog," due to the swelling's resemblance to a frog's underbelly.

Pathophysiology[edit]

Ranulas occur when there is a disruption in the normal flow of saliva from the sublingual gland. This can be due to trauma, obstruction, or congenital anomalies. The saliva leaks into the surrounding tissues, forming a cyst-like structure. There are two main types of ranulas:

Clinical Presentation[edit]

Patients with a ranula typically present with a painless, bluish, translucent swelling on the floor of the mouth. In the case of a plunging ranula, there may be a swelling in the neck as well. Symptoms can include difficulty swallowing, speaking, or breathing if the ranula is large enough to obstruct the airway.

Diagnosis[edit]

Diagnosis of a ranula is primarily clinical, based on the characteristic appearance and location of the swelling. Imaging studies such as ultrasound, MRI, or CT scan can be used to confirm the diagnosis and assess the extent of the lesion, especially in cases of plunging ranulas.

Treatment[edit]

The treatment of ranulas depends on the size and type of the lesion. Options include:

  • Marsupialization: Creating a surgical window in the ranula to allow continuous drainage.
  • Excision: Complete removal of the ranula and the affected gland.
  • Sclerotherapy: Injection of a sclerosing agent to shrink the ranula.

Recurrence is common if the underlying gland is not addressed, particularly in simple marsupialization.

Prognosis[edit]

With appropriate treatment, the prognosis for ranulas is generally good. However, recurrence can occur, especially if the sublingual gland is not removed.
