摘要
目的 探讨内镜术后局部用药对上颌窦粘膜的作用。方法 运用光镜和电镜观察了4组上颌窦药物灌注后窦口周围粘膜组织学的变化。结果 治疗前窦口周围粘膜上皮糜烂、脱落、萎缩变薄,表面纤毛大部脱落,细胞间连接松散,线粒体减少、肿胀。治疗后敏感抗生素组上皮细胞修复用,排列规则,连接紧密,纤毛再生,长短、粗细均匀、致密,胞内线粒体增多,其内嵴增多;而非敏感抗生素组及生理盐水对照组未见上皮修复。结论 慢性鼻窦炎内镜术后,应采用敏感抗生素抗感染及皮质激素药物抗变态反应,对术后鼻窦粘膜的功能恢复非常重要。
ve To investigate the effect of local medication on maxillary sinus after the surgery. Methods The histological changes of maxillary sinus mucosa were checked under optical and electronic microscopes after 4 groups of drugs were injected into the maxillary sinus cavity. Results Before the treatment the mucosa epithelium around the maxillary sinus became erosed, defluxed, atrophied and thinner. Cillia reduced largely. Cells queued loosely and vacuoles appeared between them. Mitochondrions decreased in number and swelled. After the sensitive antibiotics treatment, epithelial cells restored, queueing regularly and tightly. Cillia regenerated, growing densely and almost in the same shape. Mitochondrions and their cristae inside increased. While after the nonsensitive antibiotics and normal saline contrast treatment,there was no sign of any restoration of epithelium. Conclusion We should use sensitive antibiotics against infection andsteroid medicine against metamorphosis after functional endoscopic sinus surgery. This is very important for the functional restoration of the sinus mucosa.
