Reconstruction of the posterior auditory canal wall with a prosthesis of porous hydroxyapatite ceramic is described. The implant material is the inorganic basis of the bone matrix and is remodelled into living bone tissue. Thirty patients in whom the cavity was restored with the technique described were followed for at least 2 years, with an average of 3 1/2 years. There was no extrusion. The use of a periosteal flap and replacement of the remnants of the epithelium of the tympanic membrane and former ear canal were essential for the formation of a good epithelial lining in the new ear canal. Sufficient eustachian tube function is essential for a lasting result, as demonstrated in one patient with a recurrent otitis media. A limited retraction of the new tympanic membrane was observed without recurrent cholesteatoma in two patients.
描述了用多孔羟基磷灰石陶瓷假体重建外耳道后壁的方法。植入材料是骨基质的无机基础，可重塑为活骨组织。采用所述技术修复腔隙的30例患者随访至少2年，平均3.5年。无植入物挤出情况。使用骨膜瓣以及替换鼓膜和原外耳道上皮残余物对于在新外耳道中形成良好的上皮衬里至关重要。咽鼓管功能充分对于获得持久效果至关重要，如一名复发性中耳炎患者所示。两名患者出现新鼓膜有限内陷，但无复发性胆脂瘤。
