乳突根治术后常因反复感染,治愈相当困难。作者对24例(男8,女16,年龄18～55岁,平均40.1岁)乳突根治术后病人进行乳突重建术,取得良好效果。手术分二期进行,一期手术清除乳突腔病变,获得光滑的乳突腔骨面,并评价咽鼓管功能,用纤维蛋白混合医用陶瓷颗粒(磷酸钙40%,羟磷灰石60%,颗粒为0.5～1 mm,微孔400～600μm)填充术腔。外耳道后壁封闭材料7例为陶瓷颗粒加纤维蛋白粘合(第1组),9例为纤维蛋白骨片(第2组),8例为自家鼻中隔软骨(第3组)。鼓岬放硅胶片,以免咽鼓管鼓口上皮化,一年后 Mastoid often because of repeated infections, cure is quite difficult. The author of 24 cases (male 8, female 16, aged 18 to 55 years, mean 40.1 years) mastoidectomy patients with postoperative reconstruction achieved good results. The surgery was performed in two phases. One procedure was performed to clear the mastoid cavity, obtain a smooth mastoid bone surface, and evaluate the eustachian tube function. Fibrin mixed medical ceramic particles (40% calcium phosphate, 60% hydroxyapatite, , Particles of 0.5 ~ 1 mm, microporous 400 ~ 600μm) filled cavity. Seven cases of posterior wall occlusion of the external auditory canal were ceramic particles plus fibrin glue (group 1), 9 were fibrin septa (group 2) and 8 were nasal septal cartilage (group 3).
