Abstract
Introduction: A thorough understanding of the development and growth which involve oral and paraoral structures is necessary for the orofacial myologist. Many of the developmental anomalies are congenital as opposed to being inherited. Tongue abnormalities, whether they be developmental or acquired, are of particular interest to the orofacial myologist. The ability to recognize, evaluate and differentially diagnose these lesions is essential in order that the orotacial myologist treat the patient in a comprehensive manner.
