Trends in the Incidence and Treatment of Benign Vocal Fold Lesions in Korea, 2006–2015: A Nationwide Population-based Study
Section snippets
INTRODUCTION
Benign vocal fold lesions (BVFL) are frequently encountered in otorhinolaryngology clinics. These lesions are the most common cause of voice problems after acute laryngitis caused by transient upper respiratory infection. BVFL include vocal nodules, vocal polyps, intracordal cysts, and Reinke's edema. The prevalence of BVFL has been reported to be 2.5%–7.7% in previous national epidemiologic studies in the United States and South Korea.1, 2, 3, 4, 5, 6, 7 In South Korea, the prevalence data
Data source and study population
The NHIS shared claims database was used in this study. The NHIS is an obligatory health insurance system that presently provides cover for approximately 50 million Koreans. Health insurance policyholders and their dependents who reside in Korea are eligible for this service. Health insurance policyholders include both employees and self-employed persons, so most of the residents in South Korea are included in the NHIS. Medical aid beneficiaries and persons eligible for medical care on the
Changes in the prevalence and incidence of BVFL in Korea
The prevalence of BVFL in Korea increased by 1.7-fold from 7.07% to 12.47% during the 10-year study period. The incidence of BVFL increased by 1.5-fold from 5.29% to 7.98% during this time. Figure 1 shows the trends in prevalence and incidence from 2006 to 2015. Both the incidence and prevalence peaked in 2014.
The prevalence of BVFL increased in all age groups from 2006 to 2014. The teenage group showed the largest increase (2.51-fold) during these years. The lowest increase in prevalence
DISCUSSION
This population-based study reviewed the nationwide prevalence of BVFL and the trends in the surgical treatment of this disorder between 2006 and 2015. There have been a few reports on the prevalence of BVFL1, 2, 3, 4, 5, 6, 7; however, as far as we know, this study is the first to analyze trends in the prevalence of BVFL, changes in its incidence at a population-based nationwide level, and surgical treatment of this condition.
Our findings indicate that the prevalence and incidence of BVFL have
CONCLUSION
This population-based nationwide study in Korea demonstrated that the prevalence and incidence rates for BVFL increased between 2006 and 2015. The prevalence rate was higher in women than in men and was associated with age, income level, and presence of gastroesophageal reflux disease. The number of surgical treatments performed did not change during the study period. However, there was a decrease in the rate of surgical treatment for BVFL during this time. The observed changes may be explained

According to Jung et al.,3 the prevalence of benign vocal fold lesions in South Korea in 2015 was 12.47% and the incidence was 7.98%. According to Schultz,4 half of laryngeal cancer cases involve the vocal folds.

Males were excluded from this study given the higher prevalence of PVFLs in the female population and the likely challenges comparing outcomes measures between male and female participants.37 Patients were excluded if they had a diagnosis of vocal fold cyst on stroboscopy or if they presented with any clear concomitant diagnosis, such as paresis or significant reflux.
