To setup an experimental model is the first step to study neural regeneration. AIM: Setting up an experimental model on facial nerve regeneration. MATERIAL AND METHODS Wistar rats with complete sectioning and suturing of the extratemporal facial nerve trunk; with a behavioral and histological analysis for 9 weeks. STUD DESIGN: Experimental prospective study. RESULTS: Progressive clinical and histological recovery of the animals. CONCLUSION: Our method is acceptable to study facial nerve regeneration in rats.
