Vocal fold polyps are one of the most frequent benign laryngeal lesions, impacting the quality of voice of patients. This study aims to describe clinical characteristics, endoscopic and stroboscopic imaging in patients with vocal fold. The study used clinical images and histopathology to describe case series of 32 patients diagnosed with vocal fold polyps from august 2020 to May 2021. The study results show that the average age of the subjects was 42.1 ± 12.3; the most common risk factor was laryngopharyngeal reflux (71.8%); the most common symptoms were hoarseness (100%), of which moderate hoarseness was 59.4%), sore throat - 50%, vocal fatigue - 43.7%; total vhi-30 score was mostly at mild significant affect (71.9%); polyps were usually found in the mid-third of the free margin (65.6%) and vocal fold incompletely closed (100%). The results of stroboscopy show that the presence of mucosal waves was 96.9% and wave amplitude decreased by 68.8%. Taken together, hoarseness is the main symptom and the reason why patients seek medical attention and the position of the vocal fold polyps is usually in the mid-third of the free margin, affecting the anatomy and voice function of the vocal folds.
