慢性胆脂瘤型中耳炎中耳传导系统的重建是一尚未解决的问题,既要去除病灶,又要保留部分结构作传导系统的重建。上鼓室胆脂瘤大部分位于槌砧关节或砧骨长突附近,显微镜下很易去除,完整的或表面轻微变化的砧骨能否作听骨链重建?作者选择160例上鼓室胆脂瘤,术中肉眼见听骨几乎无变化或显微镜下仅有轻微炎症改变,取出砧骨作连续病理切片,厚度为10μm,每5张取一张作病理分析,试图回
Cholesteatoma otitis media middle ear conduction system reconstruction is an unsolved problem, it is necessary to remove the lesion, but also to retain part of the structure for the reconstruction of the conduction system. Most of the tympanosarcoma cholesteatoma is located near the mallar anvil or the incus medialis and is easily removed under the microscope. Can an intact or slightly altered surface of the incus be made for the reconstruction of the ossicular chain? The authors selected 160 cases of supratentorial cholesteatoma , Intraoperative visual bone almost no change in the auditory bone or mild inflammation under the microscope to change, remove the incus for continuous biopsy, a thickness of 10μm, take a 5 for each pathological analysis, trying to back
