Behavioral and histologic experimental model of facial nerve regeneration in rats.
To setup an experimental model is the first step to study neural regeneration.


OBJECTIVE
Setting up an experimental model on facial nerve regeneration.


METHODS
Wistar rats with complete sectioning and suturing of the extratemporal facial nerve trunk; with a behavioral and histological analysis for 9 weeks.


METHODS
Experimental prospective study.


RESULTS
Progressive clinical and histological recovery of the animals.


CONCLUSIONS
Our method is acceptable to study facial nerve regeneration in rats.
