Lymphangioma of the tongue associated with open bite: Case report

Background Lymphangioma of the tongue is a rare condition related to congenital malformations of the lymphatic system. It may have different implications such as macroglossia. This condition could exacerbate in aesthetic abnormalities and functional problems such as maxillofacial structural deformities, dysphagia, airway obstruction and speech difficulties. The aim of this paper is to describe this disease by means of a case report. Case report A 4-year-old patient was referred to our department presenting macroglossia, functional difficulty during swallowing and mastication, speech disturbances, airway obstruction, and deformities of the maxillofacial structures. Diagnosis of lymphangioma was confirmed by biopsy. After surgical removal of the lesion, the patient was treated with rapid palatal expansion, functional appliance with lingual grid and fixed multibracket appliance. After treatment, improvement in function, indicated by the gradual increase in occlusal force, could be taken as a positive sign of stability. Conclusion The 3-step treatment protocol described in this article proves to be effective in controlling the malocclusion in the three planes of the space in a patient affected by lymphangioma of the tongue.
