[Study on relationship between nail-fold microcirculation and histopathology of patients with vocal cord polyp and blood stasis syndrome].

Nail-fold microcirculation of 50 vocal cord polyp patients was observed and compared with hoarseness patients without vocal cord polyp. The results showed that peripheral microcirculation was disturbed in the vocal cord polyp patients. Histopathologic observation of 200 vocal cord polyp patients was made. It was found that principal pathologic change concentrated on the lamina propria mucosae of vocal cord and the most prominent manifestation was disturbance of topical microcirculation of Reinke's layer. In microcirculation aspect, the relationship between polyp of vocal cord and the Blood Stasis Syndrome was confirmed, and pathogenic mechanism of vocal cord polyp was discussed.
