Abstract
There are two types of surgical removal for dermoid cysts of the floor of the mouth: the intraoral approach and the transcervical approach. Intraoral resection has great cosmetic advantages, but it is sometimes difficult because of poor visibility. We report the case of dermoid cyst of the floor of the mouth in a 10-year-old boy. MRI examination suggested a sublingual dermoid cyst, so we decided to remove it via an intraoral approach. We performed endoscope-assisted intraoral resection with a good view of the lesion, and succeeded in completely removing the cyst without causing cyst rupture. Endoscope-assisted intraoral resection for dermoid cysts of the floor of the mouth is considered to be a useful method that can be performed safely with a good view of the lesion and may reduce the risk of postoperative complications and recurrence.
