Aglossia is a rare malformation resulting in the partial development or complete absence of the tongue.
Most cases of aglossia in literature have been described in correlation with other congenital or developmental defects.
Syndromes associated with Aglossia include Moebius, Hanhart, Pierre Robin, Charlie M, Pfaundler-Hurler, Orofacial-digital, Amniotic band and Glossopalantine-Ankylosis Syndrome.Mental stature is usually normal in such cases, but a case in conjunction with mental retardation has also been reported.7 Deafness has also been highlighted in some cases.8,9 Situs Inversus and more recently Hypothyroidism has also been observed with this malformation.10,11
Cranio-facial abnormalities reported in combination with this defect include cleft lip and palate, defects of the eye-lid, asymmetry of the face and cranial-nerve palsies.12 Aglossia appears to be congenital and sporadic in nature but it may be acquired due to surgery needed in case of malignancy.
The aglossia was probably compensated by the smooth floor of the mouth and the slight elevation of the floor during swallowing and speech.
The patient was not willing for any treatment for aglossia so only denture treatment was advised and replaced.
