由声带上皮增生引起声带振动结构的僵硬而导致振动幅度下降和粘膜波减少。据经验声带病变程度与振动限度相关,但无定性研究,此文目的即研究此关系。研究对象53个声带上皮增生的病人,共72侧声带,这些对象均进行了动态纤维喉镜检查及活组织检查,伴有其它异常的病人除外。分别测定了完整声带的振幅(AMP_E)和粘膜波(WAV_E)、病变部位的声带振幅(AMP_L)和粘膜波(WAV_L)的大小(它们分成四级,大、正常、小、零);并测量了病变程度的三个方面:①声带粘膜病变
The vocal cord epithelial hyperplasia causes the stiffness of the vocal cord vibrational structure to result in a decrease in the amplitude of the vibration and a decrease in mucosal waves. According to the experience of vocal cord lesions and vibration limits related, but no qualitative research, this article aims to study this relationship. Fifty-three patients with vocal cord epithelial hyperplasia, a total of 72 vocal folds, underwent dynamic fiberoptic laryngoscopy and biopsy, with the exception of patients with other abnormalities. The amplitudes (AMP_E) and mucosal waves (WAV_E) of intact vocal cords, the amplitudes of the vocal cords (AMP_L) and the mucosal waves (WAV_L) of the lesion (which are divided into four levels, large, normal, small and zero) The three aspects of the degree of disease: vocal cord mucosal lesions
