Neurectomía selectiva del nervio facial en el tratamiento de la hipercinesia contralateral en parálisis facial.

Background and objective. In the clinical approach of the peripheral facial paralysis there are therapeutic options focused on restoring facial motor function, such as static and dynamic surgeries; however, facial asymmetry is a persistent problem. Selective facial nerve neurectomy (SFNN) is a widely used surgery for the management of synkinesias and hyperkinesias as sequelae of pasalysis. Our objective is to analyze the results in the improvement of facial asymmetry of patients undergoing SFNN for the treatment of contralateral hyperkinesia of facial paralysis through the implementation of the Sunnybrook Facial Grading Scale (SFGS). Methods. A prospective observational descriptive study is designed for a sample of 100 patients diagnosed with peripheral facial paralysis treated at the Hospital de San José, Bogotá, Colombia. Demographic variables were described, and once the patients undergoing SFNN were identified, the clinical history is used to carry out the staging of the scale described and the results are compared in the pre and postoperative period. A description of the surgical technique used was made. Results. A difference in the SFGS scale classification score was identified due to an increase in the score in the postoperative period of 4 patients that were treated with SFNN with statistically significant differences. Conclusions. In our experience, SFNN is useful in the management of persistent facial asymmetry as a consequence of facial palsy. [ABSTRACT FROM AUTHOR]
