Eyelid: External levator resection

Abstract

Blepharoptosis is an unpleasant complaint of the patients referring to oculoplastic clinics. Following a thorough medical and neurologic work-up, the surgical correction is the main treatment strategy in many cases. Levator muscle function is a measure of maximal lid excursion and crucial for selecting the best surgical approach. Once the levator muscle function is measured as reasonable, along with a good Bell's phenomenon, the strengthening of the muscle by the shortening or resection techniques through an external approach can favorably elevate the eyelid.
