ABSTRACT
The goal is to present a clinical case of a baby diagnosed with ankyloglossia evaluated clinically and by surface electromyography, during bottle sucking before and after 15, 30 and 60 days of lingual frenotomy. Based on the anatomofunctional evaluation of the Tongue Frenulum Assessment Protocol in Babies, interference of the lingual frenulum was identified. The tongue, during sleep, was positioned on the floor of the mouth. The initial electromyographic evaluation of the suprahyoid muscles, during bottle feeding, showed asymmetry in root mean square (RMS) values, in microvolts (μV), between the right and left suprahyoid muscles. The evaluation was repeated after 15, 30 and 60 days after lingual frenotomy. After 15 days, appropriate lip and tongue posture, coordinated sucking movements, and absence of noises or choking were observed. After 30 days, symmetry was observed between the suprahyoid muscles, which was maintained 60 days after the surgical procedure. After lingual frenotomy, the adequacy of the position of lips and tongue, during rest and sleep, was reestablished within 15 days, and after 30 days of the procedure, there was adequacy of the tongue posture, during crying, and symmetry of the electromyographic activity of the suprahyoid muscles, during sucking. The results were maintained until the end of the study.
