Abstract

The author had experienced 67 cases of blepharoptosis to be operated, such as anterior approach (Berke, 33 cases), posterior appoach (Iliff, 24 cases) and frontalis suspension with 2-0 supramid (10 cases) from March 1967 to Dec. 1978. To obtsurgical results in blepharoptosis, it is necessary to select the appropriate operation for each case according to levator function, degree of ptosis and its etiology and the others. In cases of 5 mm or more levator function, the author attempted to resect the levator muscle through Iliff's posterior approach; but in cases of beween 3 mm and 4 mm, levator resection through Berke's anterior approach for indication of ptosis repair was selected. On the other hand, in cases of 2 mm or less levator function, frontalis suspenion was done with 2-0 supramid. "With levator resection decided upon, how much in to be resected levator muscle considering levator function and condition of its aponeurosis in each case. The results were as follows: 1. The sex distribution was in ratio of 3:2 with 36 females and 24 males. 2. In cases of unilateral ptosis, left lid was higher incidence than right lid. 3. The majority of the patients (72% of all cases) was operated between the second and the third decade. 4. The highest incidence of degree of ptosis was 3-4 mm which comprised 61% of all cases. 5. The levator functions were as follows; below 3 mm ... 34.3% (23 cases), between 4 mm and 7 mm ... 44.8% (30 cases). above 8 mm ... 25% (14 cases). 6. The good and fair surgical results were as follows; Iliff's posterior approach ... 58.3% (14 case), Berke's anterior approach ... 75.5% (25 cases), Frontalis suspension ... 29.1% (7 cases). 7. Undercorrection (12 cases, 18%) was the most common type of postoperative complication. In 12 cases of this complication, the author noted 8 cases in Iliff's posterior approach. 8. It was concluded that good surgical indications for blepharoptosis were Iliff's posterior approach with above 8 mm levator function, Berke's anterior aproach with above 3 mm levator function and frontalis suspension with below 3 mm levator function.
