Abstract
Ranulas arise as a result of the extravasation of saliva from the sublingual gland. The exact pathogenesis of ranula is still unknown. Clinically, the lesion appears as a pink or bluish fluctuant nodule that may vary in color and size. This benign lesion of the oral cavity can potentially interfere with respiration and feeding. Conventional treatment of mucocele involves a surgical approach for excision. We present a case of a newborn White male patient without a family history, with a bulla on the floor of the mouth measuring approximately 15 mm. After physical examination, the chosen treatment was conservative. After 4 cycles of cryosurgery with poor results, an ultrasound exam was performed to confirm the floating ranula. After imaging confirmation, cauterization points were performed with the aid of a high-power diode laser (2.8 W) and a reduction of the lesion was observed. There has been no recurrence since then.
