The impact of bariatric surgery on eustachian tube dysfunction

Purpose We aimed to evaluate the relationship between acute loss of weight after 6 months of bariatric surgery and the occurrence of tubal dysfunction symptoms Methods We recruited 76 patients who had undergone bariatric surgery between 2018 and 2019. It was planned to see if the change in Body Mass Index (BMI) caused changes in the Eustachian Tube Dysfunction Questionnaire (ETDQ-7) scores of individuals. Regardless of the questionnaire, patients were also asked for 3 symptoms (autophony, fullness in the ear, hearing their own breath in the ear) before and 6 months after bariatric surgery. Results The mean age of the study group was 39.32 +/- 11.09 years and 80.3% percent of the patients were female. The mean weight loss of the patients at the 6th month was 44.67 +/- 13.10 kg, and mean weight loss rate was % 35.06 +/- 8.01. The incidence of hearing their own breath, autophony and fullness of the ear were 25%, 22.4% and 11.8%, respectively. The proportion of those experiencing any of these three complaints was 30.3% (n = 23). The ETDQ scores of the cases ranged from 7 to 27, with an average of 9.38 +/- 4.28. There are 10.5% (n = 8) paints with a score of >= 14.5 as regarded as patients with Eustachian tube dysfunction (ETD). The mean age of patients with ETD was significantly higher (p < 0.05) than patients without ETD. Gender distributions, weight loss rates, smoking, previous operation and additional disease distributions do not show statistically significant differences between patients with and without ETD (p > 0.05). Conclusion Present study indicated a 10.5% ETD incidence after bariatric surgery. ETDQ questionnaire can be used for ETD screening in patients who underwent bariatric surgery, which will be an overlooked complication in this group of subjects.
