Retrospective analysis of 135 secondary alveolar cleft grafts using iliac or calvarial bone.

This retrospective study summarizes experience with 135 secondary alveolar cleft bone graft procedures over 8 years. The overall success rate was 83.7%. The group of patients (n = 108) that had particulate cancellous bone and marrow obtained from the iliac crest as donor bone had an 89.8% success rate. The group (n = 27) that had calvarial bone as the donor material had a success rate of only 63%. It is felt that inferior results with calvarial bone are probably related to the procurement technique. In both the iliac crest and calvarial groups, there was a trend toward declining success rates with advancing age of the patient. Morbidity associated with these procedures, consistent with other reported series, was low.
