Endoscope-assisted intraoral resection of external dermoid cyst

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. © 2011 Wiley Periodicals, Inc. Head Neck, 2011
