隆鼻术中羟基磷灰石重塑鼻根部的探讨

Nasion remoulding in the augmentation rhinoplasty with hydroxylapatite

对340例隆鼻术受术者术前进行鼻形态学测量,其中120例呈短鼻畸形,并接受羟基磷灰石重塑鼻根部隆鼻术。手术后效果评价表明:受术者鼻长度显著地增加,鼻长与鼻宽度比例协调,正侧面观鼻弧度及轮廓自然流畅,面部形态改善.认为对鼻长度短、额鼻角下移的受术者,应施行重塑鼻根部隆鼻术,羟基磷灰石良好的可塑性能满足不同个体鼻根部重塑,操作要点在于分离的层次应在鼻背筋膜后间隙进行,并且鼻根部分离的范围稍宽,高度超过黄金点。

The nasal measurements were carried out in 340cases undergoing augmentation rhinoplastic preoperation,of which 120cases assumed brachyrhinia(P<0.001)and had nasion remoulding in the augmentationorhinoplasty with hydroxylatite.The results indicated that the nasal length extended and aproper ratiooflength and width ofnose was achieved and anappreprate nasal contourboth from front and fromthe side was established,which was proportional to otherfacial features.It is suggested that those who have a bradyrhinia and lowerdisplacement of frontonasalangle should undergo nasion remoulding in augmentation of rhinoplasty.The excellent plasticity of HA meets the need of nasion remoulding.Thekey points in operation procedure arethat dissecting cleavage should be deep to retorfascial space of thenasaldorsum,and undermining extendin nasionshould be wider with its superior border exceeding golden point.
