Animal models remain necessary tools to study neuropathic pain. This manuscript describes the distal infraorbital nerve chronic constriction injury (DIoN-CCI) model to study trigeminal neuropathic pain in mice. This includes the surgical procedures to perform the chronic constriction injury and the postoperative behavioral tests to evaluate the changes in spontaneous and evoked behavior that are signs of ongoing pain and mechanical allodynia.

F 13640 is a recently discovered high-efficacy 5-HT1A receptor agonist that has demonstrated robust anti-allodynic efficacy in a rat model of trigeminal neuropathic pain upon acute and continuous administration. In this model, continuous morphine infusion (5 mg/day) was shown to be effective during the first week of its administration but became almost completely ineffective by the end of the second week; F 13640's effectiveness (0.63 mg/day) remained unchanged during two weeks.

Background And Purpose: Chronic constriction injury to the rat infraorbital nerve (IoN-CCI) was reported to induce asymmetric face grooming directed to the territory of the injured nerve, and localized mechanical allodynia. The model has been used for pharmacologic testing; responsiveness to mechanical stimulation has been used as outcome measure, but face grooming behavior was not studied in this context.

Methods: Face grooming data from a series of four experiments using the IoN-CCI model were retrospectively analyzed, and two types of face grooming were identified: on the one hand, isolated face grooming (i.
