Treatment of Severe Open Bite Due to Lymphangial Macroglossia

Abstract

　　Congenital lymphangiopathies are benign lesions caused by hyperplasia and dilation of lymphatic vessels resulting from abnormal lymphatic formation. Microcystic lymphatic malformations are common on the tongue and other parts of the body and cause a number of disorders, such as macroglossia, eating disorders, dysphonia, hemorrhage, and malocclusion. In this article, we describe the successful treatment of a case of severe open bite and mandibular deformity due to macroglossia secondary to abnormal lymphatic proliferation from child- to adulthood, involving multiple tongue reductions and mandibular osteotomies. Here, we present the case and report on our patient’s treatment experience along with some discussion.
