【摘要】 唇裂患者由于鼻中隔、鼻软骨、肌肉及筋膜等组织异常 ,都伴有不同程度的鼻畸形。同时 ,由于牙齿 ,周围肌群附着与结构异常、牙槽裂等又可导致上颌骨发育不足 ,使患侧梨状孔周围塌陷 ,加重了外鼻的畸形。梨状孔周围植骨可抬高鼻底 ,改变鼻肌及软组织的附着 ,使鼻畸形易矫正。取髂骨骨松质 ,行梨状孔周围塌陷区植骨术 ,如有牙槽裂 ,则一并植骨 ,手术与外鼻形矫正术可同时或分开进行。1996～ 1998年共治疗 9例 ,随诊 6～ 12月 ,效果良好。梨状孔周围植骨后 ,鼻底丰满 ,鼻翼基底上抬 ,降低鼻畸形矫正的难度 ,由于面中 1/ 3区凹陷得以改善 ,更增加了面部的整体美感。更多还原

【Abstract】 Nasal deformities due to cartilage, muscle and fascia abnormality are vary common in patients with cleft lip. maxillary hypoplasia is another important following sign. It shows depression around piriform aperture. Iliac cancellous bone transplantation are used to augment this area. So it will be easier to correct nasal deformities. To take iliac cancellous hone is the first step, then, put cancellous bone on the surface of maxillary just in depression area. Correction of nasal deformities may be done at the time of the bone graft or later. Nine patients were treated with this method from 1996 to 1998.postoperative follow up of 6～12 months demonstrated satisfactory results. cancellous bone graft around piriform orifice plays a importamt role in two stage correction of cleft lip, it can plump the bottom of nose, and alar base support, all the patients exhibited improved facial esthetics.更多还原
