Background: Surgical removal of a dermoid cyst is usually accomplished through an external neck incision. However, this procedure inevitably results in a neck scar.
Methods: We report the case of a 17-year-old woman with a submental mass. We implemented a modified approach to dermoid cyst removal through the floor of the mouth using an endoscope system.
Results: The patient received a modified approach to dermoid cyst removal and remains free of disease 6 months after excision.
Conclusion: Resection of the submental type dermoid cyst can be performed by an intraoral endoscope-assisted approach through the floor of the mouth. We describe the procedure of the endoscope-assisted intraoral resection.
