Sublingual Gland Cyst (Ranula)

Ranula is a translucent bluish mucocele of the floor of mouth due to sublingual-gland duct obstruction/rupture, presenting as painless swelling under the tongue; plunging ranula extends into neck. Treatment: marsupialization (mucosal preservation) for simple; excision of sublingual gland plus cyst for recurrent/plunging; avoid simple aspiration (high recurrence); histopathology; antibiotics if infected; follow-up to prevent recurrence.

Causes and Pathogenesis

Duct obstruction/rupture causes mucus extravasation and cyst formation.

Treatment

Marsupialization (simple); sublingual-gland excision (recurrent/plunging); avoid aspiration
