Objective: To evaluate the management of oronasal fistula with secondary alveolar bone graft after the repair of a complete cleft palate in the Fundacion Hospital de la Misericordia from 2006 to 2011.

Methods: Review of cases operated from 2006 to 2011. A total of 17 patients were operated between 7 and 14 years of age with five year follow-up (2006–2011), all cases were done in conjunction with orthodontic treatment. Iliac crest bone was the source of the graft. Follow-up consisted of clinical and radiographic examinations.

Results: In 17 patients a complete integration of the graft was observed with a complete closure of oronasal fistula, lateral incisor and/or canine eruption and development of proper dental arch form.

Conclusion: Secondary alveolar bone grafting is indicated in the management of complete cleft lip and palate. Iliac crest is the first choice as a donor source for this procedure. Orthodontic treatments are required before and after surgery. A multidisciplinary team approach is paramount for a successful treatment and rehabilitation in these patients.
