在显微喉镜检查过程中，通过显微阴道宫腔镜，对预先用亚甲蓝染色的声带上皮浅层细胞进行了活体和原位观察。评价了几个参数：上皮的规则性、细胞核的尺寸和颜色、细胞核-细胞质比、细胞核和细胞质轮廓、以及核仁、有丝分裂、细胞质内含物、角化病和挖空细胞的存在等。正常声带鳞状上皮细胞排列均匀，核呈球形，核质比例均匀。在不同的疾病，即慢性喉炎，角化病，发育不良，乳头状瘤，恶性肿瘤中观察到特定的细胞上皮模式。本研究报告了我们在68例患者中首次使用这种原始技术进行的喉显微手术中接触式内窥镜检查的结果。
By means of a microcolpohysteroscope during microlaryngoscopy, the cells of superficial layers of the vocal cord epithelium, previously stained with methylene blue, were observed in vivo and in situ. Several parameters were evaluated: regularity of the epithelium, dimensions and color of the nucleus, nucleus-cytoplasm ratio, nucleus and cytoplasm contours, and presence of the nucleolus, mitosis, cytoplasmic inclusions, keratosis, and koilocytes, among others. The normal squamous epithelium of the vocal cord has a homogeneous cell arrangement, with a spheroid and isochromic nucleus, and a uniform nucleus-cytoplasm ratio. Specific cellular epithelial patterns in different disorders were observed, namely, chronic laryngitis, keratosis, dysplasia, papilloma, and malignant tumor. The present study on contact endoscopy during microlaryngeal surgery reports our first results with this original technique, performed in 68 patients.
