Bridging the Gap: Transforming Knowledge into Action
July 8-12, 2006, Washington, DC, USA
Methods:A combined implant was developed, made of sheet titanium with special contact surfaces covered with the porous titanium. The combination titanic implants were used for replacement of the resected bone section in 11 patients with primary malignant tumors (4), and secondary lesions of the mandible (7). The sizes of the removed bone defects varied from 6 to 8 sm. Primary reconstruction was performed in 9 cases, delayed reconstruction of the mandibular continuity was achieved in 2 cases. The defects of mental soft tissues and oral cavity floor were corrected with musculocutaneous pedicle flaps from the greater pectoral muscle or musculus latissimus dorsi.
Results:Healing of operative wounds by first intention occurred in at 9 patients. We succeeded in preserving or restoring the normal outlines of the lower facial area in all these patients. The implant was removed in the postoperative period in 1 patient because of partial necrosis pectoral flap. The rest of the patients were followed up during 2 months to 2,5 years. Only in 1 case the implant was removed owing to its deteriorated fixation to the mandibular fragments. In 2 cases implant was removed because of tumor recurrence.
