A comparison of iliac and cranial bone in secondary grafting of alveolar clefts.
This retrospective study compares the success of iliac versus cranial bone autografts in the secondary grafting of alveolar clefts. The study group was 116 patients with complete records and radiographs from a pool of 186 consecutively grafted patients at Children's Hospital of Philadelphia. The quality of graft "take" was graded radiologically. Variables potentially influencing outcome were evaluated and included graft type (iliac versus cranial bone), cleft type (unilateral versus bilateral), cleft severity (complete unilateral or bilateral cleft lip and palate versus cleft of the alveolus only), age at grafting, and complications. Although graft "take" versus "nontake" seemed comparable in iliac and cranial bone graft groups, iliac bone showed a statistical superiority over cranial bone, with more radiologically excellent grades (p = 0.04) in all cleft types. Likewise, when the two graft types were compared in more severe clefts (complete unilateral and bilateral cleft lip and palate), iliac bone showed statistical superiority (p = 0.02) over cranial bone. However, they seemed comparable in less severe clefts of the alveolus only (p = 0.22). Recipient-site complications and their sequelae were comparable in iliac versus cranial graft groups, and no age-related differences were noted in children grafted above or below age 10.
