Overview
Meige syndrome, also known as hemifacial spasm, is characterized by involuntary contractions of facial muscles, typically affecting the eyelids and orbicularis oris muscles, often without a clear etiology 1.Diagnosis
Clinical presentation of involuntary spasms of facial muscles, predominantly around the eyes and mouth 1.
No specific diagnostic tests; diagnosis is primarily clinical 1.Management
First-line treatment: Botulinum toxin injections are the mainstay of treatment to alleviate muscle spasms 1.
Adjunctive measures: Lidocaine tape application prior to botulinum toxin injections significantly reduces pain during the procedure, enhancing patient comfort 1.Special Populations
No specific recommendations provided for pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 1.Key Recommendations
Utilize lidocaine tape before botulinum toxin injections to reduce pain experienced by patients (Evidence: Moderate) 1.
Botulinum toxin injections remain the first-line pharmacological intervention for managing symptoms of Meige syndrome (Evidence: Expert opinion) 1.References
