OBJECTIVE: The aim of this study was to evaluate the objective and subjective morbidity of symphyseal chin bone harvesting used for reconstruction of alveolar defects in young cleft patients. DESIGN: All patients who had undergone chin bone harvesting for alveolar cleft reconstruction in the period from 1992 through 2000 at the Department of Oral and Maxillofacial Surgery of the University Hospital Groningen, Groningen, The Netherlands, were invited to participate in this retrospective study.Patients' acceptance, perioperative and postoperative morbidity were evaluated. A survey of the medical records was performed. In addition, the patients completed a questionnaire for their appreciation of the procedure. They were also subjected to a clinical and radiographic examination. PATIENTS: Thirty patients (21 males and 9 females; mean age 11.8 +/- 3.6 years) participated in this study. RESULTS: Neither the medical records nor the experiences of the patients showed significant morbidity. The procedure was appreciated with 6.8 +/- 3.5 (scale 0 to 10). Postoperative pain was scored as 1.2 +/- 2.5 (scale 0 to 10). Three patients reported transient sensory disturbances at the donor site. Two patients showed a slight sensibility disorder in the symphyseal region. In three patients, an endodontic problem had developed in a lower incisor. CONCLUSION: This study showed that chin bone harvesting for reconstructing alveolar cleft in young patients is a well-accepted procedure with low objective and subjective morbidity. Notwithstanding this low morbidity, the patients (and their parents) have to be informed about the risk of objective and subjective disturbances of the sensibility in the donor region and the risk of dental pulp necrosis.
