TIBIA AS DONOR SITE FOR ALVEOLAR BONE GRAFTING IN PATIENTS WITH CLEFT LIP AND PALATE: LONG TERM EXPERIENCE

Abstract

Tibial bone grafts were studied in 137 patients with clefts of the lip and palate. Twenty-one had clefts of the lip and primary palate and 116 had complete unilateral clefts of the lip and palate. Bone grafting was performed secondarily or late secondarily. Bone was harvested from the proximal part of the tibia distal to the tuberosity through an incision about 15 mm long. The mean follow-up time after bone grafting was 5.5 years (range 2-11). There were no operative, or early or late postoperative complications reported (such as haematoma, fracture, or shortening of the limb). Harvesting time was about 15 minutes. The possibility of operating with two teams makes the total operating time shorter. Bleeding was negligible (less than 15 ml) and the amount of bone obtained was always sufficient. Patients were mobilised the next day and were back to full physical activity by one month. Indications for tibial bone grafting included facilitation of tooth eruption into the graft, giving bony support to the neighbouring teeth, making it possible to insert a titanium fixture, raising the alar base of the nose, and closing an oronasal fistula. Compared with iliac, cranial, mandibular, and costal donor sites, using the tibia took less time, gave less bleeding, made it possible for two teams to operate simultaneously, gave a smaller scar, and there were minimal complications and satisfactory quantity and quality of bone in all cases. The results suggested that the tibia is an excellent choice of graft for residual alveolar clefts in patients with cleft lip and palate.
