Eyelid ptosis is drooping of the upper eyelid to a position that is lower than normal due to a congenital or acquired abnormality of the motor system that elevates the eyelid. Ptosis can result from a lesion at any point along the pathway between the cerebral cortex and the levator muscle. Congenital ptosis often results from myogenic dysgenesis of the levator palpebrae superioris. In such cases, the levator muscle and aponeurosis tissue are replaced by fat and fibrous tissue, reducing the ability to contract or relax.
Frontalis suspension is a commonly used surgery that is indicated in patients with blepharoptosis and poor levator muscle function. This surgery connects the eyelid to the brow with a sling material and utilizes the power of the frontalis muscle to elevate the poorly functioning eyelid. In congenital ptosis cases, it is recommended that surgery be deferred until the…
