 Symptoms associated with macroglossia may include drooling; speech impairment; difficulty eating; stridor; snoring; airway obstruction; abnormal growth of the jaw and teeth; ulceration; and/or dying tissue on the tip of the tongue. The tongue may protrude from the mouth. Inherited or congenital disorders associated with macroglossia include Down syndrome, Beckwith-Wiedemann syndrome, primary amyloidosis, and congenital hypothyroidism. Acquired causes may include trauma, cancer, endocrine disorders, and inflammatory or infectious diseases. Isolated, congenital macroglossia can be genetic, inherited in an autosomal dominant manner. Treatment depends upon the underlying cause and severity and may range from speech therapy in mild cases, to surgical reduction in more severe cases.Macroglossia is the abnormal enlargement of the tongue in proportion to other structures in the mouth. It usually occurs secondary to an underlying disorder that may be present from birth (congenital) or acquired. In rare cases, it is an isolated, congenital feature.
