Comparative Study of Multimodal Therapy in Facial Palsy Patients

Area of Science:

• Neurology
• Rehabilitation Medicine
• Plastic Surgery

Background:

• Chronic facial palsy often leads to synkinetic muscle overactivity and stiffness, impairing facial movement and function.
• Multimodal therapy aims to address these complex issues in facial palsy management.

Purpose of the Study:

• To evaluate the effectiveness of multimodal therapy in improving functional outcomes for patients with chronic facial palsy.
• To assess the impact of treatment timing on the outcomes of multimodal facial rehabilitation.

Main Methods:

• Seventy-five facial palsy patients underwent facial rehabilitation.
• Treatment needs (therapy, chemodenervation, surgery) were assessed using the East Grinstead Grade of Stiffness (EGGS).
• Outcomes were measured using the Facial Grading Scale (FGS), Facial Disability Index, House-Brackmann scores, and the Facial Clinimetric Evaluation scale.

Main Results:

• Significant improvement in Facial Grading Scale (FGS) composite scores post-therapy (p < 0.0001).
• Substantial reduction in synkinesis observed (p < 0.0001).
• Late presentation ( > 2 years) correlated with increased need for chemodenervation, higher botulinum toxin doses, and greater stiffness (EGGS scores).

Conclusions:

• Multimodal facial rehabilitation is effective for chronic facial palsy, including cases with neglected synkinesis.
• Patients presenting later than 2 years post-onset still benefit from multimodal treatment, though potentially to a lesser degree due to muscle contracture.
• Early intervention in facial palsy management is recommended to maximize treatment efficacy and minimize long-term complications.
