Dysontogenic cyst of the oral floor excision by preserving Wharton's duct by micro-surgical repair and relocation to floor of the mouth - A clinical case report.

A 20-year-old female presents with a painless, progressive, normal color smooth surface sublingual swelling extending to chin that had gradually increased in size over the preceding 2 months, which severely impaired her speech and swallowing. Fine-needle aspiration biopsy was suggestive of benign cystic lesion. Following surgical excision, the mass was found to contain a large amount of sebaceous keratin material removed along with the entire capsule of the cyst. Definitive diagnosis was confirmed with histological examination. We report a case of dermoid cyst treated surgically through an intra-oral approach by preserving and relocating the Wharton's duct using micro-surgical repair to the floor of the mouth, thereby leading to a good cosmetic and functional result for the patient.
