作者报告了29例用埋植各种形态多孔型磷灰石的方法,矫正唇裂外鼻畸形。在鼻翼基部上颌骨骨面,即梨状孔侧缘附近埋植该材料者12例,鼻小柱部5例,鼻尖部15例。从鼻根至鼻柱以鼻修复术的形式使用2例,共计34个部位。在临床应用之前,进行了动物实验,把一块3×15mm,气孔率约60％的多孔型磷灰石,埋植在成年狗的下颌骨体部骨膜下,一月后观察,在与骨面相接处,由骨表面向磷灰石气孔内渗入了新生骨。磷灰石底部与骨面
The authors reported 29 cases of implanting various forms of porous apatite method to correct cleft lip nose deformities. In the nasal base of the maxillary bone surface, that is, the edge of the pear-shaped hole near the implant material in 12 cases, 5 cases of nasal columella, nasal tip in 15 cases. From the nasal root to the nasal column nasal repair in the form of two cases, a total of 34 sites. Prior to clinical use, animal experiments were performed. A 3 × 15 mm porous apatite with a porosity of about 60% was implanted under the periosteum of an adult dog's mandibular body. After one month of observation, Phase at the junction, the surface of the apatite pores into the new bone. Apatite bottom and bone surface
