Congenital ptosis. Results of treatment using lyophilized fascia lata for frontalis suspensions.

In a prospective collaborative study, congenital ptosis was repaired using lyophilized allogeneic fascia lata as the suspension material for frontalis sling procedures. Over 50 cases of unilateral and bilateral ptosis procedures were performed by pediatric ophthalmologists during the initial study period. No infections or evidence of tissue rejection were reported during a follow-up period of up to 24 months. Four failures, ascribed to slippage, were noted within the first several months and required regrafting. In an additional case, minimal slippage occurred, but resulted in satisfactory lid levels. All remaining cases achieved satisfactory cosmetic and functional results. Most collaborators found this form of preserved fascia lata to be superior to nylon polyfilament, cable-type suture. Clinical features of the patient population included a high incidence of strabismus (28%) and amblyopia (24%).
