RÉSUMÉ (en anglais)

Objective: To study the effects of the “Mirror Effect Plus Protocol” (MEPP) on global facial function in acute and severe Bell’s Palsy.

Design: Single blind and randomized controlled trial to compare the effects of basic counselling (control group) vs MEPP (experimental group) over one year.

Setting: Outpatient clinic following referrals from Emergency or Otorhinolaryngology Departments.

Subjects: 40 patients (n=20 per group) with moderately severe to total palsy who received standard medication were recruited within 14 days of onset. Baseline characteristics were comparable between the groups.

Interventions: The experimental group received the MEPP program (motor imagery + manipulations + facial mirror therapy) while the control group received basic counselling. Both groups met the clinician monthly until 6 months and at one-year post-onset for assessments. 

Outcome measures: Facial symmetry, synkinesis, and quality-of-life were measured using standardized scales. Perceived speech intelligibility was rated before and after therapy by naïve judges. 

Results: Descriptive statistics demonstrated improvements in favor of the MEPP for each measured variable. Significant differences were found for one facial symmetry score (House-Brackmann 2.0 mean (SD) = 7.40 (3.15) for controls vs 5.1 (1.44) for MEPP), for synkinesis measures (p= 0.008) and for quality-of-life ratings (mean (SD) score = 83.17% (17.383) for controls vs 98.36% (3.608) for MEPP (p = 0,002)). No group difference was found for perceived speech intelligibility. 

Conclusion: The MEPP demonstrates promising long-term results when started during the acute phase of moderately severe to total Bell’s Palsy.
