Mandibular reconstruction using hydroxylapatite granules, autogenous bone, and a cervical island skin flap

Ten patients with gingival carcinoma who were treated by marginal mandibulectomy were reconstructed using hydroxylapatite granules, autogenous bone chips, and a cervical island skin flap. The cervical flap was used to produce a cover and partition, designed to prevent the displacement of the mixture of hydroxylapatite and bone. Reconstruction was successfully achieved in all patients. Loss of height of the reconstructed mandible over an average 18-month follow-up ranged from 8% to 22%. One patient has worn a full denture and five patients wear partial dentures.
