| Abstract |
|
Epidermoid cysts located in floor of mouth can be easily removed intraorally. The cysts inferior to mylohyoid muscle have been excised transcervically. However, an intraoral removal of a cyst extended inferior to mylohyoid muscle has not been reported yet. A 20-year-old female visited to the hospital with a cystic mass in submental region. Neck computed tomography revealed a 6.0×4.3cm sized circumscribed cystic mass in midline of sub-mental area. The cyst lied external to the genioglossal and geniohyoid muscle, extending inferior to mylohyoid muscle. The mass was removed successfully by intraoral approach. It was performed under the exposure by the division of genioglossal and geniohyoid muscle, traction of the cystic wall after aspiration of the cyst, and digital compression externally. |
