“…Therefore, the ET is one of the most important organs affected by preoperative excess weight and rapid postoperative weight loss in this specific patient group. There are several studies in literature regarding this issue, all of which, except 1, have evaluated patients who have undergone bariatric surgery 1,4 . As retrospective studies have an inherent bias, the current study was designed to be prospective.…”

“…There are several studies in literature regarding this issue, all of which, except 1, have evaluated patients who have undergone bariatric surgery. 1,4 As retrospective studies have an inherent bias, the current study was designed to be prospective. Another problem is that there is no exact method to measure ET function objectively and previous studies have predominantly analyzed the ET function through subjective survey assessment.…”

“…it is preferred for the elimination of medical, physical, psychological and economic outcomes of morbid obesity. 1 However, rapid and effective weight loss with this surgery can lead to various effects on other organs. One of these organs is the eustachian tube (ET), which has an important function in the ventilation, clearance and protection of the middle ear.…”

Objective: To investigate the effect of weight loss after bariatric surgery on eustachian tube (ET) function with video endoscopy. Materials and Methods: The present study was conducted as a prospective cohort and was completed with 19 patients. Three-step tympanometry (basal, Toynbee, Valsalva), dynamic slow-motion video endoscopy, and the Eustachian Tube Dysfunction Questionnaire-7 (ETDA-7) were applied to the patients preoperatively before bariatric surgery and in the postoperative 6th month. Dynamic slow-motion video endoscopy was graded between 0 and 3, or classified as patulous, as indicated in the literature. Results: The mean body mass index of 6 male and 13 female patients decreased from 47.3 AE 4.6 to 31.2 AE 5.4. Grade decline (median 2 AE 1) was experienced in all patients in DSVE, and 1 patient resulted as patulous ET. The ETDA-7 scores decreased in11 patients, remained stable in 7 patients, and increased in 1 patient with patulous ET. The statistical analysis of the preoperative and postoperative DSVE grading and ETDA-7 scores, excluding the patulous ET patient, was found to be significant (P ¼ 0.001 and P ¼ 0.003, respectively). There was no significant change in any of the tympanometry parameters (P > 0.05). Conclusions: Rapid weight loss with bariatric surgery results in an improvement in both the DSVE images and in the complaints of ET dysfunction in the majority of patients, but in some patients it may result in patulous ET. Therefore, preoperative evaluation of the ET with DSVE and questioning the patient's complaints are important in predicting patients who may develop patulous ET.

“…The cartilaginous portion of the ET is partially surrounded by adipose tissue that may help to maintain the tube in the normal closed position; loss of this tissue may predispose to PET. Several studies suggest that PET is relatively common following bariatric surgery (Alhammadi, Jönsson, Olbers, & Yassin, 2009; Muñoz, Aedo, & Der, 2010; Pascoto et al, 2014; Yazici, Gunes, Koc, Gunes, & Sayin, 2021), and PET incidence in this population appears to correlate with the degree and rapidity of their weight loss (Muñoz et al, 2010).…”

Objective To assess for the prevalence of autophony, a distressing auditory symptom commonly attributed to patulous eustachian tube, in a cohort of individuals with severe malnourishment due to an eating disorder. Method A cross‐sectional survey study was performed. Patients admitted for inpatient medical stabilization of an eating disorder, who were also at low body weight, were asked to complete a survey assessing aural symptoms present in the previous 24 hr, including autophony. Anthropometric data and prealbumin levels were collected. Results Of 101 patients enrolled, 43 (42.6%) reported symptoms of autophony. The presence of autophony was associated with lower serum prealbumin levels and lower body weight as measured by percentage of ideal body weight. Discussion Autophony is a commonly reported, albeit rarely discussed, symptom in individuals with severe eating disorders and correlates with degree of malnutrition.

“…2,3 Weight loss is a frequently reported risk factor for PET. Several studies show an increased incidence of PET following rapid weight loss after bariatric surgery, 4,5 and PET occurring following weight loss from other causes such as chronic diseases or cancer therapy is also described. 6,7 It has been postulated that loss of adipose tissue surrounding the cartilaginous portion of the ET plays a causal role in the development of PET.…”

Objectives To understand the presence of transient autophony symptoms in patients being treated for severe anorexia nervosa (AN), and whether those symptoms were due to patulous eustachian tube (PET). Methods A prospective observational study was performed in patients requiring admission for treatment of severe AN. All enrolled patients completed The Eustachian Tube Dysfunction Questionnaire (ETDQ‐7) and were screened for symptoms of autophony. If patients reported autophony and had a score of ≥14.5 on the ETDQ‐7 they were asked to undergo comprehensive audiological testing and an evaluation with an otolaryngologist. Results Of the 73 patients enrolled in the study, 35 patients (44%) reported autophony and 36 (49%) scored 14.5 or higher on the ETDQ‐7. Of the 16 (22%) patients who had both autophony and an ETDQ‐7 score of 14.5 or higher, 7 patient s (representing 11 symptomatic ears) underwent evaluations by audiology and otolaryngology. Every evaluation of a symptomatic ear revealed objective evidence of PET. Nine of 11 (81.8%) symptomatic ears had subjectively resolved within 12 days of admission after nutritional rehabilitation and weight gain. Conclusion Transient autophony in severe AN patients is due to PET, and was present in at least 8% of patients within our cohort. Further study is warranted to understand the quality of life impact and pathophysiology of transient PET in this patient population.
