Hypoglossia-hypodactylia syndrome is an extremely rare congenital anomaly characterized by a hypoplastic mandible, absence of the lower incisors, hypoglossia, and a variable degree of absence of the digits and limbs, with a risk of dysarthria and dysphagia. We report the articulation function and the swallowing function of a patient with hypoglossia-hypodactylia syndrome who was followed up to eight years old. Our patient did not have feeding and swallowing disturbances. She did not have articulatory disturbance, including /t/ and /r/, of the sound articulated using a proglossis. In the future, it is necessary to have a plastic operation for abnormal adhesion of the lower lip and mandibular gingiva and depression on the lower lip, and distraction osteogenesis for micrognathia. Also, it will be necessary to continuously monitor for an articulatory disturbance until the child uses more words. Therefore, a long-term intervention with a multidisciplinary approach is necessary.
