Ok-432 (Picibanil) In the Treatment of Ranulas

appearance of the ‘tail sign’ is vital for distinguishing plunging ranulas. However, these images are insufficient to differentiate between cystic hygroma, second branchial cleft cyst, or dermoid cysts [4]. USG can be used preoperatively to determine the characteristics of pediatric ranulas, and are a radiation-free and a rather inexpensive modality [2]. Plunging ranula diagnosis is complicated due to the absence of clinical features apart from a swelling in the neck. In this case, FNAC is useful for diagnosis. Amylase and Mucin are positive in the yellow aspirate in the ranula, whereas lymphatic malformations often contain cholesterol crystals and lymphoid and endothelial cells in watery aspirates [5].
