Giant Dermoid Cyst of Floor of the Mouth with Extention to the Base of Tongue: Case Report and Review of the Literature
Introduction: Oral floor dermoid cysts are a rare entity. A cyst can cause malfunctions in the upper aerodigestive tract and slurred speech. The treatment of choice is essentially surgical. Case report: A 17-year-old male who presented with progressive swelling in the floor of the mouth since birth. Clinical examination revealed a painless, bulky, and symmetrical swelling in the floor of the mouth, pushing the tongue backward. Discussion: Giant oral floor cysts located under the mylohyoid muscle are usually removed extra orally. We report the case of a large dermoid cyst of the floor of the mouth, with extension at the base of the tongue, removed intraorally. Conclusion: The recommended surgical techniques vary according to the size and anatomical situation of the cysts. The intraoral approach is preferred for cysts that do not extend beyond the mylohyoid muscle.
