[Surgical therapy of blepharospasmus gravis]

Area of Science:

• Neurology
• Ophthalmology
• Surgical Techniques

Context:

• Blepharospasm, a rare condition causing orbicularis oculi muscle cramps, significantly impacts patient quality of life.
• Existing therapeutic approaches for blepharospasm have often yielded unsatisfactory outcomes.
• A surgical technique involving dissection of the zygomatico-temporal branch of the facial nerve was introduced in the mid-1970s.

Purpose:

• To report on the author's experience and long-term results using the Walser/Behbehani surgical technique for blepharospasm.
• To evaluate the therapeutic value of facial nerve branch dissection in treating blepharospasm.
• To compare the efficacy of this surgical method with existing literature.

Summary:

• The study details the long-term outcomes of 19 patients who underwent surgery for blepharospasm, involving dissection of the zygomatico-temporal facial nerve branch.
• Surgery was performed bilaterally in 19 patients and unilaterally in 5, followed by upper eyelid blepharoplasty.
• Follow-up periods ranged from 3 months to 14 years, assessing the effectiveness of the surgical intervention.

Impact:

• Provides valuable data on the long-term efficacy of a specific surgical intervention for blepharospasm.
• Offers insights into an alternative treatment option for patients with severe blepharospasm unresponsive to other therapies.
• Contributes to the understanding of surgical management for movement disorders affecting the facial nerve.
