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.
本研究调查了在二期牙槽骨植骨术中接受部分下鼻甲切除术患者的特征及预后情况。55例唇腭裂或唇裂合并牙槽突裂患者在进行二期牙槽骨植骨术的同时，有33例接受了部分下鼻甲切除术，以确保腭裂侧和非患侧鼻底高度相近。手术时，接受下鼻甲切除术的患者明显比未接受该手术的患者年龄大。唇腭裂患者中接受下鼻甲切除术的比例明显高于唇裂合并牙槽突裂患者。这些差异显然反映了下鼻甲的发育阶段以及牙槽突和腭裂缺损的相对严重程度。在大多数接受部分下鼻甲切除术的患者中，术后X线片显示植骨部位骨形成良好。我们的研究结果表明，二期牙槽骨植骨术中进行部分下鼻甲切除术是一种非常有用的手术，有助于解剖至鼻底高度、重建鼻底黏膜以及形成足够的骨桥。它还能促进牙槽裂闭合，尤其是在骨缺损较大的患者中。
