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.
