[Follow-up study of bone grafts to the alveolar clefts].
Clinical follow-up study after the grafting with fresh autogenous iliac bone to the alveolar clefts in cleft lip and palate patients was carried out up to 2 years post operation. Twenty two patients were examined, to whom grafts of iliac cortical or iliac marrow bone was carried out by the First or the Second Department of Oral Surgery, Kagoshima University Dental School from July, 1985 to April, 1988. Their cleft types were classified as 18 unilateral and 4 bilateral cleft lips and palates. The ages at bone grafting were ranged from 8 years 9 months to 17 years 6 months, and the average of which was 12 years 3 months. Nine of these patients were grafted with the cortical bone, and the other 13 were grafted with the marrow bone. The perforations at alveolar clefts were covered with the tongue flap in 10 clefts of 10 patients, while they were covered with the local mucous flap in 15 clefts of 12 patients. Among these patients, dental casts, X-ray radiograms and oral pictures of 15 patients were surveyed postoperatively. Results were as follows: 1) Contours of the alveolar clefts were well corrected in 9 patients, especially in those cases of pre-operatively expanded unilateral clefts, grafted with the marrow bone and covered with the local mucous flaps. 2) The viable rate of grafted bone was 100.0% for the marrow bone, while it was 62.5% for the cortical bone.(ABSTRACT TRUNCATED AT 250 WORDS)
