Severe congenital hypoglossia: a case report.

Hypoglossia is referred to a small volume and/or size of the tongue. It is a rare congenital condition caused by failed embryogenesis of the lateral lingual swellings and tuberculum impar during the fourth to eighth weeks of gestation. The anomaly has often occurred in association with limb abnormalities and various syndromes, and it affects facial and mandibular growth. The present report describes a case of severe congenital hypoglossia in a female infant, her systemic and dentofacial features, and the initial management.
