Context And Objective: One of the techniques used for treating facial paralysis is double muscle innervation using end-to-end neurorrhaphy with sectioning of healthy nerves. The aim of this study was to evaluate whether double muscle innervation by means of end-to-side neurorrhaphy could occur, with maintenance of muscle innervation.
Design And Setting: Experimental study developed at the Experimental Research Center, Faculdade de Medicina de Botucatu, Unesp.
