ABSTRACT
BACKGROUND: Autologous vascularized bone transfer is the preferred strategy for the reconstruction of mandibular defects in a pediatric population. The principal argument is the theoretical postoperative growth potential of the neomandible, which uses vascularized donor tissues.
OBJECTIVES: The purpose of this study was to objectify the veritable growth potential of vascularized bone transfers in children.
METHODS: A literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, revealing 57 patients younger than or equal to 18 years who had undergone a mandibular reconstruction with a vascularized free flap. Only studies using postoperative imaging were included. Outcomes regarding growth and postoperative corrections and complica tions were analyzed.
RESULTS: Neomandibular growth was observed in 63.2% of all included patients. The proportion of growth was higher in patients with condylar preservation (95.7%) than that of patients with condylar involvement (41.2%). Reconstruction of the condyle by a free flap, which includes an epiphyseal growth plate or cartilage increased postoperative growth potential (77.8%) but did not reduce the need for later orthognathic surgery.
CONCLUSION: After mandibular reconstruction with a vascularized bone transfer, the majority of pediatric patients shows neomandibular growth. Condylar preservation, the inclusion of epiphyseal growth plates or cartilage, and the patients age at the time of reconstruction are essential defining parameters.
