The great number of operations described over the past century for correcting blepharoptosis is indicative of the difficulty of achieving a standardized technique. It will be consistently effective condition that has so many variations of degree and individual operative technique is so important.
To obtain the best surgical results in blapharoptosis, it is necessary to select the appropriate operation for each case according to levator function, degree of ptosis, its etiology and the others. In generally, if the levator function is poor or abscent, sling of the upper lid to frontalis muscle is recommended and if levator function is good, resection of the levator is the treatment of choice. But some authors (Blaskovics & Jaensch) believe that resection of the levator will give an excellent result even when little preoperative levator action is evident.
Authors have experienced 25 patients (27 eyes) of the moderate to severe degree of blepharoptosis who have received the levator resection, from January 1980 to January 1984 and could have done follow up studies for at least 6 months.
The results were obtained as follows;
1. In most cases, the patients were satisfied except 6 cases complicated; one case of entropion and five cases of undercorrection.
2. Even if levator function was poor (below 2 mm, 7 cases), good surgical results have been obtained by resection of levator(21-25 mm or above).
