Partial inferior turbinectomy during secondary alveolar bone grafting.
This study examined the characteristics and outcome of patients undergoing partial inferior turbinectomy during secondary alveolar bone grafting. Thirty-three of 55 patients with cleft lip and palate or cleft lip and alveolus who underwent secondary alveolar bone grafting concurrently received partial inferior turbinectomy to ensure that the height of the nasal floor was similar on the cleft side and non-affected side. At the time of surgery, patients who underwent turbinectomy were significantly older than those who did not undergo the procedure. The proportion of patients who underwent turbinectomy was significantly higher among patients with cleft lip and palate than among those with cleft lip and alveolus. These differences apparently reflected the developmental stage of the inferior turbinate and the relative severity of alveolar and palatal defects. In most patients who underwent partial inferior turbinectomy, postoperative X-ray films revealed excellent bone formation at the graft site. Our findings suggest that partial inferior turbinectomy during secondary alveolar bone grafting is a very useful procedure that facilitates dissection to the height of the nasal floor, reconstruction of the mucosal nasal floor, and formation of a sufficient bone bridge. It also promotes alveolar cleft closure, especially in patients with wide bone defects.
