Rehabilitation methods for orofacial linkage after facial palsy mainly include botulinum toxin injection therapy, physical rehabilitation therapy and surgical treatment.
1. Botulinum toxin injection treatment: Botulinum toxin injection can reduce unnecessary muscle contraction, the most common areas for Botulinum toxin injection include orbicularis oculi and buccal muscles, etc. Patients with orofacial palsy need to be maintained for a long period of time when they receive Botulinum toxin treatment.
2. Physical rehabilitation therapy: the main method is to promote patients to maximize the voluntary control of facial muscles with the help of various aids (such as electromyographic feedback system, mirror, tape, etc.) under the effects of vision, touch and hearing. For example, in patients with orofacial linkage, the eye muscles are controlled as much as possible when the mouth movements are completed.
3. Surgical treatment: Surgical treatment options for orofacial linkage after facial palsy mainly include selective peripheral neurotomy, neurolysis, selective myotomy, occlusal nerve-facial nerve anastomosis, and trans-facial nerve grafting, etc. The muscles that lead to the unnatural movements will be cut off or excised, or the branches of the facial nerves controlling the linkage will be cut off, so as to minimize the linkage.
Patients are advised to seek timely medical attention and treatment under the guidance of a specialized physician to avoid adverse consequences.
