Abstract

The ultrastructural appearance of the regenerated middle ear mucosa--found at the second operation of staged intact canal wall tympanoplasty (ICWT) with mastoidectomy--has been evaluated with the transmission electron microscope. The regenerated epithelium showed all the morphologic characteristics of the normal middle ear mucosa: ciliated cells, nonciliated cells, and secretory cells. All of these (including goblet cells) have been found in the specimens. It is concluded that a normal middle ear mucosa regenerates to cover all denuded bone surfaces after the first operation of staged ICWT with mastoidectomy, when silicone rubber sheeting has been used to prevent adhesions and maintain an air-containing middle ear space.

摘要

在分期进行的完整外耳道壁鼓室成形术（ICWT）联合乳突切除术的第二次手术中发现的再生中耳黏膜的超微结构，已通过透射电子显微镜进行了评估。再生上皮呈现出正常中耳黏膜的所有形态学特征：纤毛细胞、无纤毛细胞和分泌细胞。在标本中均发现了所有这些细胞（包括杯状细胞）。得出的结论是，在分期ICWT联合乳突切除术的首次手术后，当使用硅橡胶片来防止粘连并维持含气的中耳腔时，正常的中耳黏膜会再生以覆盖所有裸露的骨表面。
