Secondary alveolar bone grafting in cleft lip and palate: A comparative analysis of donor site morbidity in different age groups.

INTRODUCTION

There is no consensus regarding the optimal timing for secondary alveolar bone grafting for clefts defects. We aimed to investigate the potential correlation between the age of patients during surgery, donor site symptoms, surgical time and hospitalization following this procedure.

MATERIAL AND

METHODS

The outcome of 195 consecutive alveolar bone grafting procedures among different age groups (mean: 7.1 years; range 1.8-40.5) was retrospectively assessed based on a chart review and purpose-prepared report forms. The association between age, gender and hospitalization following bone harvesting was tested by Spearman rank correlation, while relationships (i.e. between age and pain) were evaluated by logistic regression.

RESULTS

The most frequent donor site complaints included: pain equal to or exceeding that of the recipient site (93%) and gait disturbances (92.5%) immediately after the procedure. Chronic complaints included: iliac contour alteration (40.1%), unsightly scar (23%) and recurring discomfort (2.1%). Statistical analysis showed no correlation between donor site symptoms, their duration or hospitalization time following surgery at different ages, except a higher incidence of significant pain immediately after bone harvesting in older females (r = 0.268; p = 0.030).

CONCLUSION

Alveolar bone grafting at an earlier age does not increase donor site symptoms, surgical duration or hospitalization following surgery.
