Secondary mandibular reconstruction for paediatric patients with long-term mandibular continuity defects: a retrospective study of six cases.

Paediatric patients with long-term mandibular continuity defects following segmental resection usually present severe functional and cosmetic deformities. Secondary mandibular reconstruction for these patients is very challenging. Literature reports on how to handle these patients are scarce. The aim of this study was to describe the authors' experience in handling those paediatric patients who have not undergone primary reconstruction, for whom the final goal of treatment is to restore a symmetrical facial appearance, masticatory function, and speech. This was a retrospective analysis of the data of six patients who underwent radical mandible resection in childhood, without immediate bone restoration, and who then underwent a secondary mandibular reconstruction procedure after reaching adulthood, during the period 2009 to 2015. The multidisciplinary treatment procedure, selection of the donor site, and reconstructive approach are discussed. Key points in relation to secondary mandibular reconstruction with the aim of achieving not only good functional and cosmetic results, but also an improvement in the paediatric patient's psychological and social outcomes, are emphasized.
