Results. They underwent the results the test of t of Paired Student obtaining: The basal activity doesn't present a difference statistically significant to 95% of trust, in the opposing values (t = 2.23; 5 gl; p = 0.076), the insert activity presents a difference statistically significant to 95% of trust (t = 6.708; 5 gl; p = 0.001). Conclusion. Clinically the electromyographic changes demonstrate that a not specific inflammatory process exists, without functional damage after the cleft lip repair. [ABSTRACT FROM AUTHOR]
