Objective:
To demonstrate a method for reduction of wide alveolar clefts prior to bone grafting. This method aims to facilitate bone grafting and achieve adequate soft tissue coverage of the graft with attached gingiva.
Case Report:
Treatment of a patient with bilateral cleft lip and palate with a severe alveolar defect on the left side is illustrated. Distraction osteogenesis was used to mesialize the left segment so that the alveolar cleft was reduced to a minimum. After a 10-week retention period, bone grafting of the reduced alveolar defect was successfully performed. After consolidation of the bone graft, the alveolar cleft was found to have an osseous closure with adequate soft tissue coverage.
Conclusion:
In patients with a wide alveolar cleft, soft tissue coverage with keratinized mucosa can be more readily assured by reducing the alveolar cleft by callus distraction to mesialize the lateral segment prior to bone grafting.
