羟基磷灰石微粒人工骨隆鼻术50例八年随访

为探讨羟基磷灰石（简称ＨＡ）微粒人工骨作为隆鼻术移植材料的远期效果，对ＨＡ人工骨植入隆鼻的５０例受术者进行了８年随访观察。通过受术者对手术效果的自我评价，临床医师对术后有关指标的客观检查，同时通过Ｘ线片对ＨＡ置入体的位置，形态及与鼻骨的关系进行了观察分析，随访观察的结果表明，ＨＡ微粒人工骨隆鼻术手术效果良好，ＨＡ作为隆鼻术的充填材料远期疗效稳定，是一种理想的具有生物活性的新型隆鼻材料。

Augmentation rhinoplasty with particulate hydroxy apatite artificial bone in 50 cases--a follow-up of 8 years]

To investigate the long term results of the particulate hydroxy apatite (HA) artificial bone in augmentation rhinoplasty, 50 patients were followed up for 8 years after the operation. The clinical study included the patient's self-evaluation and the surgeons' objective evaluation of the operation results, analysis of nasal radiographs for the position, shape of the HA implant and its relation with the nasal bone. The observations show that HA is stable and the long-term results of augmentation rhinoplasty with HA are very good. It is concluded that HA is a new, ideal, bioactive filling material for augmentation rhinoplasty.
