关于鼻窦炎的研究已有80～90年的历史,其间虽有不少成果,但迄今为止,临床上仍感鼻窦炎患者治疗上及手术后处理方面的困难。近年来继抗菌药物之后,虽有酶制剂等新药问世,在手术方法上亦有改进,使鼻窦炎的治疗有显著的进步,但仍不能收到完全根治的满意效果。由于慢性鼻窦炎发病机理包括各种内、外因素的复杂作用,故难于查明其发病过程。在这个问题上,仅依靠单一的对策是不能最终解决问题的。因而,作者从新的角度对鼻窦粘膜,特别是上颌窦炎的粘膜病理改变加以研究,以期对解决慢性鼻窦炎的本质问题有所裨益。其方法为:用实体显微镜观察手术采取的全部上颌窦粘膜,将各种粘膜表面的变化与病理组织学所见进行对比。这样,可以全面了解窦粘膜的病态而不致遗漏,从窦粘膜上皮鳞化乃至癌变的学说来看,结合临床 About sinusitis has been 80 to 90 years of history, although there are many achievements, but up to now, still clinically sinusitis patients treated and postoperative treatment difficulties. In recent years, following the antibacterial drugs, although the advent of new drugs such as enzyme preparations, there are improvements in surgical methods, the treatment of sinusitis have made significant progress, but still can not receive completely cured the satisfactory results. As the pathogenesis of chronic sinusitis, including a variety of internal and external factors, the complex role, it is difficult to identify the pathogenesis. On this issue, relying solely on a single solution can not finally solve the problem. Therefore, the author from a new perspective on the mucosa of the sinuses, especially mucosal pathological changes of maxillary sinusitis in order to solve the essential problems of chronic sinusitis benefit. The method is: using a solid microscope to observe the operation of all the maxillary sinus mucosa, a variety of mucosal surface changes and histopathological findings were compared. In this way, we can fully understand the pathological sinus mucosa without omission, squamous epithelium from the sinus mucosa and even cancer theory, the combination of clinical
