In order to restore function and esthetics in mandibular hypoplasia, transplantation of osteochondral grafts and the distraction osteogenesis technique are used alternatively. In a retrospective study the indication, growth and complication rate of osteochondral graft and distraction osteogenesis cases in mandibular hypoplasia were compared. In total, 12 patients (4-14 years old; 7 female, 5 male) with different grades of mandibular hypoplasia received osteochondral grafts (7 costochondral, 5 iliac crest; observation period 4-9 years). In 5 patients (10-12 years old; 1 female, 4 male), distraction osteogenesis was performed (observation period 10 months to 3 1/2 years). In the results, according to the literature, the range of growth after osteochondral grafting varied considerably, approximate normal growth was noticed in only two cases. On the other hand, all patients treated by distraction osteogenesis showed a stable increase of bone length as expected. After osteochondral grafts, adequate growth is to be expected in the minority of cases and it does not seem predictable in individual cases. Therefore, the indication for osteochondral grafts should be restricted to severe hypoplasia, where the local amount of bone does not allow the use of a distraction device, and to cases where support of the mandibula at the skull base is necessary. In all other cases of mandibular hypoplasia in children, distraction osteogenesis should be discussed as the primary option, even if in the long term a second surgical procedure should be necessary.
