Demographic Profile and Risk Factors of Patients with Benign Vocal Fold Lesions Diagnosed through Laryngeal Videoendoscopy and Stroboscopy

Objective: To determine the prevalence of benign vocal cord lesions among Filipino patients in a tertiary institution and identify the demographic characteristics and possible risk factors found among these patients. Methods Study Design: Retrospective case series Setting: Private tertiary hospital Subjects: Records of 2,375 patients who underwent laryngeal video endoscopy and stroboscopy from 2012-2014 were reviewed. Results: There were 632 records of patients with benign vocal fold lesions, of which nodules were most common (211, 33.38%), followed by Reinke’s edema (165, 26.10%), cysts (122, 19.30%), and polyps (74, 11.70%), with hoarseness as the most common symptom (542, 85.76%). More than half (336, 53.16%) were aged 21-40 years, and almost two-thirds (469, 74.21%) were female. The most common associated factors were caffeine intake (445, 70.41%) and inadequate water intake (370, 58.54%), followed by alcohol (253, 40.03%). Smoking was only present in 146 (23.19%). Conclusion: Baseline evidence on the prevalence of benign vocal fold lesions in this institution as well as baseline data on the common characteristics and associated factors seen in the sample population may assist us in current practices and guide future studies directed toward treatment and prevention.
