Brief summary

A research study to find out if brief intraoperative electrical stimulation therapy improves nerve regeneration and smile outcomes following two-stage cross face nerve graft facial reanimation surgery.

Detailed description

Participants that choose to enroll in this study will be randomly assigned in a 2:1 ratio to a treatment or control group. In either group, patients will receive the same care as they normally would except for two minor differences. First, patients in both groups undergo nerve biopsies during surgery; these biopsies do not affect the length or outcome of surgery. Second, the treatment group will receive brief electrical stimulation therapy for approximately 10 minutes during the first stage cross-face nerve graft surgery. The purpose of this study is to evaluate efficacy of an intraoperative dose of brief electrical stimulation (BES) to improve axonal regeneration across a cross-face nerve graft (CFNG) using nerve histology and to evaluate clinical outcomes of treatment and control groups using clinician graded, patient reported, and objective smile metric.

Masking description

This is a randomized, controlled, double-blinded (patient and evaluator) prospective study. Plan is to enroll up to 30 patients, with a minimum of 20 completing full follow-up. Randomization 2:1 treatment to control due to previous peripheral nerve research demonstrating intraoperative stimulation accelerates axonal regeneration

Intervention model description

Patients will undergo all the standard steps of the facial reanimation procedures. The difference in care is 2/3 participants may receive the brief electrical stimulation therapy. Other 1/3 of study participants will undergo the surgery as they normally would if they had not chosen to participate.
