Effectiveness of Minimally Invasive Partial Orbicularis Myectomy for Treating Benign Essential Blepharospasm: A Study Using the Jankovic Scale and Blepharospasm Disability Index

Minimally invasive partial orbicularis myectomy demonstrates significant and sustained improvement in both symptom severity and functional disability in patients with benign essential blepharospasm refractory to botulinum toxin treatment. The combined application of Jankovic Rating Scale and Blepharospasm Disability Index proves to be an effective approach in evaluating surgical outcomes, offering valuable insights into both the clinical efficacy of partial orbicularis myectomy and its impact on patients' daily functioning.
