Long-term results of frontal lobe suspension in children with congenital dystrophic ptosis

Long-term results achieved by our own operative technique in children with congenital dystrophic ptosis, with frontal muscle lobe shaping with or without shaping of corrugator muscle lobe attached to the tarsal plate, are presented. Data on 146 patients with congenital dystrophic ptosis operated on during the 1984-1998 period at Zagreb University Hospital Center were retrospectively analyzed. Postoperative success was defined as a situation with eyes open in which 1) upper eyelid covers the cornea at 12 o'clock position by 1-2 mm; 2) there is a good contour of the eyelid margin; 3) there is no lagophthalmos; and 4) there is symmetry with the other eye. Immediate re-operation due to undercorrection was required in 26 of 146 (18%) patients. Upon re-operation, 133 (91%) patients met the criteria for successful outcome at 6 months, 124 (85%) at one year, and 121 (83%) at 5 years. Correction of congenital dystrophic ptosis using a shaped frontal/corrugator lobe is an efficient and safe procedure ensuring long-lasting success.
