萎缩性鼻炎是本科常见鼻病。本病疗法极多,但效果不够满意。采用致密多晶羟基磷灰石微粒人工骨(Hydroylapatite particle artificial bone:HA人工骨)鼻腔粘骨下植入术治疗萎缩性鼻炎,国内外报道较少。我院自1987年10月起用该材料治疗萎缩性鼻炎患者共368例,其中108例经术后2年以上临床观察,效果满意,现作一初步介绍。一、HA人工骨的理化特性 HA人工骨是人体正常骨的主要无机成份。1987年,美国路易斯安娜州大学的Rent等学者首先提出用HA人工骨整复萎缩牙槽嵴,通过动物实验和国
Atrophic rhinitis is a common undergraduate nose disease. The disease treatment is very much, but the effect is not satisfactory. Hydroxyapatite particle artificial bone (HA artificial bone) nasal cavity for the treatment of atrophic rhinitis, less reported at home and abroad. Our hospital since October 1987 with the material for the treatment of patients with atrophic rhinitis a total of 368 cases, of which 108 cases after more than 2 years of clinical observation, the results are satisfactory, is now a preliminary introduction. First, the physical and chemical properties of HA artificial bone HA artificial bone is the main inorganic components of normal human bone. In 1987, the University of Louisiana, Rent and other scholars first proposed using HA artificial bone atrophy shrinkage alveolar ridge, through animal experiments and the country
