Abstract: Aim The aims of this study were to perform clinicopathological analyses of teratoid cysts of the floor of the mouth and to assess the possibility of surgical treatment.
Materials and methods The incidence, manifestations, histogenesis, treatment and prognosis of 10 patients admitted to our department between April 2000 and May 2008 were reviewed.
Results Teratoid cysts occurred almost exclusively in neonates and children, and appeared as mobile, cystic solid and well-defined lesions. Because of the special location, consequences such as difficulty in feeding, breathing and even impairment in growth and development frequently occur. Results of histological examination indicated that squamous, respiratory and gastrointestinal epithelium composed the basic structure of teratoid cyst. Transonogram, CT and MRI examination were conducted, and complete surgical excision was the only treatment of choice. Usually, immediate treatment is not necessary unless the cyst obstructs the upper airway. There has been no recurrence of the lesion after surgery.
Conclusion Although teratoid cyst of the floor of the mouth is a cystic disease, it affects patients to a great extent because of its special location. Therefore, early and complete excision is mandatory for good prognosis.
