A Clinical Study of 16 Cases of Ranula

Ranulas are conventionally treated by total resection, marsupialization or intracystic OK-432 injection. We clinically studied 16 such cases from 2000 to 2008—15 sublingual and 1 mixed. The ranula was excised in 7 cases with recurrence in 42.9%, marsupialized in 3 with 100% recurrence, the sublingual gland totally resected in 4 with no recurrence, and OK-432 injected intracystically in 2 with 50% recurrence. Our results thus suggest that total sublingual gland resection is an effective method for the treatment of ranula.
