Clinical and electromyographic evaluation of infant with ankyloglossia pre and post frenotomy - case report.

Introduction: Ankyloglossia is a congenital anomaly that can restrict tongue movements. It affect habitual position of lips and tongue and impacts the functions of chewing, speech and suction. Objective: Purpose of this study, aproved to Ethical Comitee Research, is to present a case repor of a three months old infant with ankyloglossia and congenital torticollis affecting breastfeeding assessed clinically and by surface electromyography (SEMG) before and after frenotomy. Resumed report: The clinical evaluation was performed through protocol for the evaluation of the lingual frenulum in infants, validated for application in Brazil. Initially, lip posture half-open and tongue in floor of mouth during sleep was observed. Tendency to tongue position during crying in the midline with sides in elevation. SEMG evaluations of the right and left suprahyoid muscles were collected for four minutes during bottle feeding. The averages in RMS values collected were 49.44 microvolts in left suprahyoid muscles and 25.32 microvolts in right suprahyoid muscles. After frenotomy, closed resting lip posture was observed, a tendency to position the tongue during crying in midline with the body in elevation and the tongue positioned on the palate during sleep. Suction with coordinated movements, reduction of feeding time from 18 to 8 minutes on average with no noise and choking and SEMG of left suprahyoid muscles 34.72 microvolts and right suprahyoid muscles 32.72 microvolts. Conclusion: After frenotomy, the lip was closed, tongue was in palate during sleep and suction was adequated confirmed by clinical and electromyographic evaluation. [ABSTRACT FROM AUTHOR]
