Methods. Illustration of the ventral aspect of the rat facial soft tissues (A) and a magnified view of the lower lip and skin innervation territory of the mental nerve (B). A partial injury of the left mental nerve was performed either by loosely ligating it with two 6/0 chromic gut sutures or by tightly ligating ⅓ to ½ of its diameter with a single 6/0 silk suture. The areas stimulated for behavioural testing are outlined and the tissue harvested for NGF quantification and innervation density measurement are also indicated.
