Anatomy of the upper eyelid and its significance in correction of eyelid ptosis
Objective To explore anatomic features of the upper eyelid for improving clinical effect on the ptosis correction. Methods 132 patients with mild or moderate ptosis were followed up during 3 years. Most cases were treated with surgical levator shortening or folding. Levator muscle flap was dissected carefully intraoperatively, which was shortened or folded according to the degree of ptosis. The aortic arch, lacrimal gland and other important structures were protected during the operation. Whitnall ligament was cut or not according to the specific conditions. Results The correction was satisfied for most patients, except for 3 cases of under-correction, one case of over-correction, and 2 cases of asymmetrical eyelid lines. Conclusions The key process for the correction of eyelid ptosis is to isolate levator muscle flap, and evaluate the shorten degree of the levator, according to the anatomic features of the upper eyelid.
