Large Oral Ranula - Secondary to Trauma

Ranula is a benign mucous containing, thin walled swelling which is caused by either rupture or blockage of major or minor salivary gland ducts. We present a case of a healthy 46 year male patient who presented with a 14 days history of swelling under the tongue, accompanied by discomfort while swallowing. He revealed a history of trauma of the maxillofacial region 2 months earlier. Local examination revealed a soft non tender fluctuant mass on the floor of the mouth extending bilaterally with seemingly normal mucosa. A clinical diagnosis of Ranula was arrived at and the lesion was subjected to marsupialization under Local Anesthesia. The aim of this article is to present a case of a giant bilateral Ranula located on the floor of the mouth and to discuss the various diagnostic and treatment modalities.
