Patulous Eustachian Tube

This article presents 2 cases of extremely intractable patulous Eustachian tube following multiple transnasal shim insertion. These cases highlight the disadvantages of repeat transnasal shim operations, including enlargement of the Eustachian tube lumen, frequent dislocation, repeat surgery, recurrent middle ear infection, and shim misswallowing. The patients in these cases were successfully treated with Eustachian tube cartilage chip insertion through a postauricular approach. We describe the surgical technique and advantages of this promising management method.

Abstract Objectives This study aimed to analyse if there were any associations between patulous Eustachian tube occurrence and climatic factors and seasonality. Methods The correlation between the monthly average number of patients diagnosed with patulous Eustachian tube and climatic factors in Seoul, Korea, from January 2010 to December 2016, was statistically analysed using national data sets. Results The relative risk for patulous Eustachian tube occurrence according to season was significantly higher in summer and autumn, and lower in winter than in spring (relative risk (95 per cent confidence interval): 1.334 (1.267–1.404), 1.219 (1.157–1.285) and 0.889 (0.840–0.941) for summer, autumn and winter, respectively). Temperature, atmospheric pressure and relative humidity had a moderate positive (r = 0.648), negative (r = –0.601) and positive (r = 0.492) correlation with the number of patulous Eustachian tube cases, respectively. Conclusion The number of patulous Eustachian tube cases was highest in summer and increased in proportion to changes in temperature and humidity, which could be due to physiological changes caused by climatic factors or diet trends.

Purpose This paper aims to validate the Korean version of the decent work scale and examine the relationship between decent work and work engagement. Design/methodology/approach After completing translation and back translation, the authors surveyed 266 Korean employees from various organizations via network sampling. They assessed Rasch’s model based on item response theory. In addition, they used classical test theory to evaluate the decent work scale’s validity and reliability. Findings The authors found that the current version of the decent work scale has good validity, reliability and item difficulty, and decent work has a positive relationship with work engagement. However, based on item response theory, the assessment showed that three of the items are extremely similar to another item within the same dimension, implying that the items are unable to discriminate among individual traits. Originality/value This study validated the decent work scale in a Korean work environment using Rasch’s (1960) model from the perspective of item response theory.
