Cambios electromiográficos del músculo orbicular del labio después de la reparación de labio hendido en conejos.

Introduction. Multiple techniques of repair of cleft lip have been developed. Achieving an excellent aesthetic result; However the surgical techniques to cleft lip repair have not been able to restore the function in the orbicularis muscle, obtaining plane and inexpressive lips. Material and methods. You forms a group of 6 rabbits New Zealand race from 2.5 to 3 kg of weight that underwent an electromyographic study to obtain the basal activity and the insert activity in a study pre and post operative (Cleft lip repair) to document electromyographic changes compatible with alteration in the function of the orbicularis muscle. 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]
