We report a case of endoscopic-assisted complete removal of a dermoid cyst in the floor of the mouth.
A 56-year-old woman presented to our otorhinolaryngology clinic with a history of recurrent infection of the floor of the mouth. She had been treated for an oral floor abscess at a previous hospital. However, in view of recurrent infection of the same area of the mouth she was referred to our department for further examination and treatment. Imaging examination showed a mass in the central floor of the mouth, which was suspected as a dermoid cyst. We successfully performed complete resection of the tumor in the oral floor via an intraoral approach. Because the poor macroscopic view limits proper visualization of the lesion near the mental spine, we used an endoscope-assisted intraoral approach. The endoscope-assisted intraoral approach provided a good view of the lesion, and we succeeded in complete removal of the cyst without causing cyst rupture.
