A ranula is a mucous cyst found on the floor of the mouth. For a plunging ranula, the cyst extends beyond the sublingual space (the space below and beneath the tongue) and may interfere with the mylohyoid muscle (a muscle forming the floor of the oral cavity). A plunging ranula also goes by the names of cervical ranula or diving ranula. It is the least common form of ranula. In addition to swelling in the oral cavity, it may also cause swelling in the neck.
