Frontalis suspension sling using a silicone rod in patients affected by myogenic blepharoptosis.
The charts of 10 patients affected by myogenic ptosis who underwent surgical correction by means of a frontalis suspension sling using a silicone rod were reviewed. The patients included in the study were affected by ptosis secondary to myasthenia gravis (MG), chronic progressive external ophthalmoplegia (CPEO) or mitochondrial myopathy (MM). In every patient the ptosis was severe (MRD( 1) < 2 mm), with the eyelid partially or totally occluding the visual axis; levator function was poor (<5 mm), Bell's phenomenon was poor or absent and the orbicularis function was reduced. Final eyelid height, patient satisfaction and the presence of complications were our main outcome measures. Analysis of the results showed that the ptosis was corrected in every patient with a clear visual axis. One patient with absent Bell's and poor levator function had exposure keratopathy resistant to medical treatment and required surgical revision. We believe that the frontalis suspension sling is safe, effective and is the procedure of choice for patients affected by poor-function acquired ptosis. A silicone rod, because of its elasticity, is the material of choice in this selected category of patients.
