ABSTRACT
BACKGROUND:
Non-flaccid facial palsy sequelae manifest as sequelae following Bell's palsy. Currently, there are no effective remedies for addressing this issue. In this study, we proposed a new surgical solution, epineurectomy of the extracranial facial nerve trunk, and assessed its safety and efficacy as a potential remedy..METHODS:
In this single-arm trial, adult patients with non-flaccid facial palsy sequelae were enrolled and subjected to epineurectomy of the extracranial facial nerve trunk. The primary efficacy endpoint was the Sunnybrook scores at months 12 postoperatively. The secondary endpoints included non-flaccid facial palsy sequelae symptom scores, such as facial tightness or facial stiffness, facial synkinesis, eyefissures narrowing or difficulty in opening the eyes, House-Brackmann grade scale, and Facial Disability Index.RESULTS:
A total of 22 patients were enrolled between July 2020 and January 2021. One patient was lost to follow up. One year after surgery, the Sunnybrook score was 72.0 (63.0 - 75.0) at 12 months versus 68.0 (58.0 - 70.8) at baseline. The mean difference was -5.4 (-7.2 to -3.6). The scores of facial tightness or facial stiffness, synkinesis, eye fissures narrowing or difficulty in opening eyes were 0.0 (0.0 - 1.0), 1.0 (1.0 - 1.0), 1.0 (1.0 - 2.0) at 12 months versus 3.0 (1.3 - 3.0), 2.0 (1.0 - 2.8), 2.0 (2.0 - 3.0) at baseline, respectively. The median (IQR) values of the Facial Disability Index physical function were 92.0 (90.0 - 95.0) at months 12, and the mean difference (95% CI) was -32 (-38 to -26) compared to baseline. The mean difference (95% CI) in the Facial Disability Index social/well-being function between month 12 and baseline was -38 (-46 to -31).CONCLUSIONS:
Epineurectomy of the extracranial facial nerve trunk can effectively and safely alleviate the sequelae of non-flaccid facial palsy.
