RESECTION and advancement of the levator palpebrae superioris gives the best functional and cosmetic result of any ptosis operation. As a rule, operation on the levator is indicated if there is a degree of function in this muscle. Myasthenia gravis, the myopathies, jaw-winking, and related anomalies of innervation are the exceptions to this rule. Bowman was perhaps the first to attempt correcti...

purpose: to evaluate the outcomes of ptosis surgery in patients with weak levator function using orbicularis oculi and frontalis muscles. methods: this prospective interventional case series study was conducted over 3 years on patients with ptosis and weak levator function (less than 4mm). in all cases, orbicularis oculi and frontalis muscles were used directly to correct the ptosis. success wa...

A 39-year-old woman was diagnosed with myasthenia gravis when she was 8 years old. Although many treatments - such as cholinesterase inhibitors and steroids - had been given to the patient, her condition did not improve sufficiently. As she demonstrated bilateral 3 mm levator function without any eye movement disturbances, bilateral frontalis sling procedures were performed with an autologous f...

PURPOSE To report the results of a modified frontalis sling procedure using Mersilene mesh for correction of upper lid ptosis associated with poor levator muscle function. METHODS This interventional case series included 10 patients (15 eyelids) with congenital ptosis and poor levator function. All subjects underwent the upper lid sling procedure with modifications. Main outcomes were lid cre...

purpose: to compare mersilene mesh and autogenous fascia lata in the management of low-function ptosis. methods: a randomized clinical trial was performed on 31 eyelids with poor levator function. patients were randomly assigned to two groups: 16 eyelids in the mersilene mesh group and 15 eyelids in the autogenous fascia lata group. results: nine patients with congenital unilateral and 11 patie...
