Official Description

Marsupialization of sublingual salivary cyst (ranula)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Marsupialization of a sublingual salivary cyst, commonly referred to as a ranula, is a surgical procedure aimed at treating mucoceles that develop in the floor of the mouth. These cysts typically arise due to trauma to the sublingual gland or duct, obstruction of the duct, or infection of the gland. When the gland or duct is damaged, mucous can escape and accumulate in the soft tissues of the floor of the mouth, leading to the formation of a cyst. The procedure involves exposing the cyst, excising its roof, and suturing the wall of the cyst to the surrounding mucosa. This technique allows the cyst to heal from the inside out, promoting proper recovery and minimizing the risk of recurrence. Unlike excision procedures, where the entire cyst is removed, marsupialization preserves the cyst's structure while facilitating drainage and healing, making it a less invasive option for managing sublingual salivary cysts.

1. Indications

The procedure of marsupialization of a sublingual salivary cyst (ranula) is indicated for the following conditions:

  • Submandibular duct obstruction - This condition occurs when the duct that drains saliva from the submandibular gland is blocked, leading to the formation of a cyst.
  • Trauma to the sublingual gland - Injury to the gland can result in the leakage of mucous, causing a cyst to form in the floor of the mouth.
  • Infection of the sublingual gland - Infections can lead to inflammation and subsequent cyst formation, necessitating surgical intervention.

2. Procedure

The marsupialization procedure involves several key steps to ensure effective treatment of the cyst:

  • Step 1: Exposure of the cyst - The surgical team begins by making an incision over the cyst to carefully expose it. This step is crucial for visualizing the cyst and surrounding structures, allowing for precise dissection.
  • Step 2: Dissection - The cyst is meticulously dissected from the surrounding tissue. During this process, care is taken to avoid damaging adjacent anatomical structures, such as the sublingual salivary gland, submandibular duct, and lingual nerve, which are critical for normal function.
  • Step 3: Roof excision - Once the cyst is adequately exposed, the roof of the cyst is excised. This step is essential for facilitating drainage and promoting healing.
  • Step 4: Suturing - The walls of the cyst are then sutured to the surrounding mucosa. This technique helps to create a stable opening that allows the cyst to drain and heal properly.
  • Step 5: Packing - Finally, the lumen of the cyst is packed with gauze. This packing aids in maintaining the opening and supports the healing process from the inside out.

3. Post-Procedure

After the marsupialization procedure, patients can expect a recovery period that may involve some discomfort and swelling in the area. Post-operative care typically includes instructions for oral hygiene to prevent infection and promote healing. Patients may also be advised to avoid certain foods that could irritate the surgical site. Follow-up appointments are essential to monitor the healing process and ensure that the cyst is resolving as expected. Any signs of complications, such as increased pain, swelling, or signs of infection, should be reported to the healthcare provider promptly.
