In practice, it poses two major problems, the first one is the eminent risk of amblyopia during severe congenital ptosis, and the second is of an aesthetic nature, representing the main reason for consultation. The aim of this work is to evaluate the interest of the levator palpebrae superioris muscle plication in the ptosis surgery. Materials and Methods: We collected 12 patients who received a correction of their ptosis by plication of the levator palpebrae superioris muscle over a period of 3 years from January 2012 to December 2014. Result: The mean age at treatment was 22 years;the ptosis was congenital in 8 cases, and acquired in 4. The ptosis was major in 67% and moderate in 33% of the cases. Muscle plication was the basic surgical technique in all patients in our series. The function and aesthetic results were satisfying in 6 cases (50%), good in 4 cases (34%), acceptable in 1 case and bad in 1 case (8%). Discussion: The comparative study has shown that the plication of the levator palpebrae superioris muscle is a possible alternative for the correction of ptosis whatever the type of ptosis with results comparable to the reference technique compared to the degree of correction, whereas the operative follow-up is simpler and more minor complications. Conclusion: The surgical treatment of ptosis should be done after a systematic clinical examination and after very precise indications. However, the plication of the levator muscle of the upper eyelid has shown its functional and aesthetic efficiency in congenital ptosis and in the ptosis of the adult.展开更多
