Abstract
Objectives

The aim of this study is to estimate the entire population-based prevalence and incidence of Patulous Eustachian tube (PET) using the Korean National Health Insurance (NHI) claims database. The annual trends of prevalence and incidence of PET were also investigated.

Methods

Retrospective analysis of PET patients was performed between 2010 and 2016, from the NHI claims database. PET patients were defined as those who had at least one service claim with a primary diagnosis under an ICD-10-based PET code (H69.0).

Results

During the study period, there were 20,533 new PET patients in Korea. In 2016 there were 4482 incident cases, and the standardized annual incidence rate was 8.8 per 100,000 persons. The standardized annual prevalence rate increased significantly from 7.2 per 100,000 persons in 2010 to 10.3 per 100,000 persons in 2016. The prevalence increased significantly on annual basis, whereas the incidence rate fluctuated over time. Interestingly, the incidence and prevalence of PET in women was almost twice as high as that in men, and peaked in their 20s.

Conclusions

This study demonstrated the substantial annual increase of the NHI claims with PET code (H69.0) in Korea from 2010 to 2016. Statistical results based on the NHI claims, we confirmed the high prevalence and incidence rates of clinically significant PET in women than in men. This study only covered patient using the medical service for PET and missed PET sufferers not seeking medical service. However, this study can provide basic epidemiological information on clinically significant PET.
