Eustachian tube dysfunction (ETD) affects a significant portion of the population, manifesting symptoms that impact the quality of life. Despite the prevalence of ETD, there remains a notable gap in comprehensive studies exploring the condition\'s dynamics within specific demographic contexts, particularly within Saudi Arabia. This study aimed to assess the prevalence and severity of ETD across different demographic groups, to evaluate the efficacy of various treatment modalities, and to identify key predictors of treatment response in a Saudi Arabian cohort. A cross-sectional study was conducted from June 2022 to May 2023 in tertiary care hospitals in the Aseer region, Saudi Arabia. Participants included adults diagnosed with ETD, assessed through clinical symptoms, otoscopic examinations, audiometric evaluations, tympanometry, and the ETDQ-7 questionnaire. The study incorporated advanced diagnostics such as nasopharyngoscopy and pressure equalization tube function tests and involved 154 participants, revealing significant variations in ETD severity, with the 46-60 age group exhibiting the highest mean ETDQ-7 score of 4.85, and urban residents displaying lower severity scores compared to rural counterparts. Pharmacological interventions were most effective, achieving the highest symptom relief and audiological improvement rates of 87.78%. Multivariate regression highlighted age, geographic location, and treatment modality as key predictors of treatment efficacy, with notable interaction effects between climate conditions and treatment types influencing outcomes. The findings underscore the heterogeneity in ETD presentation and the differential efficacy of treatment modalities.

OBJECTIVE: This study aims to evaluate the validity and reliability of tubomanometry (TMM) in diagnosing obstructive Eustachian tube dysfunction (OETD) before balloon Eustachian tuboplasty (BET).
METHODS: A prospective cohort study was conducted, involving 25 patients with sinonasal pathology, 75 patients with middle ear disease, and 25 healthy subjects, totaling 250 ears. All participants underwent comprehensive physical examinations, including TMM, nasal videoendoscopy, otoendoscopy, Valsalva maneuver (VM), tympanometry, and audiometry. Additionally, various scales such as ETDQ-7 and ETS-7 were employed. Tympanometry served as the gold standard for assessing OETD, and comparisons were made among the measures across the three groups.
RESULTS: Among the 125 participants, 44.8% (n = 56) were female, and 55.2% (n = 69) were male, with ages ranging from 19 to 93 years (M = 48.5; SD = 15.6). In our study, VM demonstrated high sensitivity (86.3%) when tympanometry was considered the gold standard. Conversely, TMM, ETDQ-7, and ETS-7 exhibited high specificity, with ETDQ-7 showing the highest specificity (87.4%). Regarding TMM, all R values in patients within the middle ear disease group were pathological (R > 1).
CONCLUSIONS: TMM has exhibited notable specificity as a diagnostic tool compared to tympanogram and VM. Nonetheless, the combination of TMM and ETDQ-7 has enabled us to conduct a diagnostic assessment with high sensitivity and specificity for chronic OETD diagnosis.

UNASSIGNED: To evaluate the feasibility of local anesthesia for Eustachian tube balloon dilation as an in-office procedure for the treatment of Eustachian tube dilatory dysfunction as a response to the restriction measures of the coronavirus disease 2019 pandemic.
UNASSIGNED: Patients with Eustachian tube dilatory dysfunction refractory to nasal steroids undergoing Eustachian tube balloon dilation in local anesthesia were enrolled in a prospective observational cohort between May 2020 and April 2022. The patients were assessed by using the Eustachian tube dysfunction questionnaire (ETDQ-7) score and Eustachian tube mucosal inflammation scale. They underwent clinical examination, tympanometry, and pure tone audiometry. Eustachian tube balloon dilation was performed in-office under local anesthesia. The perioperative experience of the patients was recorded using a 1-10 visual analog scale (VAS).
UNASSIGNED: Thirty patients (47 Eustachian tubes) underwent the operation successfully. One attempted dilation was aborded because the patient displayed anxiety. Local anesthesia was performed by using topical lidocaine and nasal packing for all patients. Three patients required an infiltration of the nasal septum and/or tubal nasopharyngeal orifice. The mean time of the operation was 5.7 min per Eustachian tube dilation. The mean level of discomfort during the intervention was 4.7 (on a 1-10 VAS scale). All patients returned home immediately after the intervention. The only reported complication was a self-limiting subcutaneous emphysema.
UNASSIGNED: Eustachian tube balloon dilation can be performed under local anesthesia and is well tolerated by most patients. In the patients reported in this study, no major complications occurred. In order to free operation room capacities, the intervention can be performed in an in-office setting with satisfactory patient feedback.

UNASSIGNED: This study aims to identify clinical predictors of treatment response to Eustachian Tube Balloon Dilation (ETBD) as measured by changes in Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) scores.
UNASSIGNED: One hundred thirteen patients who underwent ETBD at an institution from 2017 to 2021 completed ETDQ-7 pre- and post-operatively. We conducted multivariable regression analyses with ETDQ-7 normalization (<2.1 post-op), minimum clinically important difference (MCID) (>0.5 pre-op - post-op), and quantitative improvement in ETDQ-7 score as outcome variables. Pre-operative ETDQ-7 score, tympanogram type, chronic otitis media, chronic rhinosinusitis (CRS), inferior turbinate hypertrophy, deviated septum, allergic rhinitis, and rhinorrhea were included as covariates. Models controlled for age, sex, ethnicity, prior ear or sinus surgery, and follow-up duration.
UNASSIGNED: The mean age was 49 years old. 51% were females, and all patients had pre-operative ETDQ-7 above 2.1. After a mean follow-up period of 13 months, 77% achieved MCID and 37% had normalized. Higher pre-operative ETDQ-7 score was associated with greater ETDQ-7 score improvement (B = 0.60, 95% CI = [0.37, 0.83]) and greater odds of achieving MCID (aOR = 1.65; 95% CI = [1.06, 2.59]). A history of CRS improved chances of achieving MCID (aOR = 4.53; 95% CI = [1.11, 18.55]) and a history of chronic otitis media predicted increased odds of ETDQ-7 normalization (aOR = 2.88; 95% CI = [1.09, 7.58]).
UNASSIGNED: Our findings suggest that ETBD was highly effective among patients with pre-operative ETDQ-7 above 2.1. Furthermore, higher pre-operative ETDQ-7 score, CRS, and chronic otitis media predicted more favorable symptomatic benefit from ETBD. These factors may be important to consider when counseling potential candidates for this procedure.

OBJECTIVE: To identify the characteristics of tympanogram in symptomatic Eustachian tube dysfunction (SETD) patients.
METHODS: One hundred and twenty-four unilateral SETD patients presenting with type A tympanograms who underwent balloon dilation of the Eustachian tube (BDET) were recruited and assigned into effective BDET group and ineffective BDET group based on treatment effect. The unaffected ear in the same patient served as normal control. Fifty-one patients with sudden sensorineural hearing loss (SSHL) and 46 patients with Meniere\'s disease (MD) were selected for cases of non-ETD ear fullness. Demographics, 7-item Eustachian Tube Dysfunction Questionnaire score (ETDQ-7), and tympanograms were recorded and analyzed preoperatively and postoperatively.
RESULTS: Of the 124 SETD patients included in the study 94 (75.8%) showed good response to BDET based on decreased ETDQ-7 scores. There were no significantly differences in the values of tympanometric peak pressure (TPP) between diseased ears and healthy ears in SETD patients, as well as in SSHL and MD patients. Instead, TPP shifts (the difference between two values of TPP obtained under a Valsalva and Toynbee maneuver) were remarkably reduced in affected ears compared with those in unaffected ears in effective BDET group at baseline. Moreover, TPP shifts in these SETD ears significantly raised and reached the levels in healthy ears postoperatively.
CONCLUSIONS: This study demonstrated TPP shifts are decreased in a subset of SETD patients presenting with type A tympanograms and these patients are more likely to show good response to BDET.

BACKGROUND: Otological disorders, including Eustachian tube dysfunction (ETD), are commonly observed in divers. Data were gathered to observe the prevalence of ear disorders, and awareness of ear health recommendations for recreational divers in the United Kingdom.
METHODS: An anonymous online survey included: diver/diving demographics, the validated Eustachian Tube Dysfunction Questionnaire 7 (ETDQ-7) (a mean score of ≥ 2.1 indicating the presence of dysfunction), pre-existing ear health conditions, medications, decongestants and knowledge of diving and ear health guidance.
RESULTS: A total of 790 divers (64% males) responded (age range 16-80, median 47 years). An ETDQ-7 mean score of ≥ 2.1 was calculated in 315 of 790 respondents (40%), indicating varying degrees of ETD; 56/315 (18%) recorded a pre-existing ear condition. Ear disorders, (external, middle, and inner ear issues) since learning to dive were recorded by 628/790 (79%) of respondents; 291/628 (46%) did not seek medical advice. ETDQ-7 scores of ≥ 2.1 to 6.6 were reported by 293/628 (47%). Six reported inner ear decompression sickness. Decongestants were used by 183/790 (23%). Two hundred and seventy-seven of 790 divers (35%) had aborted a dive with ear problems. Only 214/790 (27%) of respondents were aware of the United Kingdom Diving Medical Committee guidance regarding ear health and diving.
CONCLUSIONS: Ear problems and ETD since diving were widely reported in this cohort of divers, with not all divers in this study aware of ear health recommendations and advice.

Objective:To evaluate the Eustachian tube function of children with simple adenoid hypertrophy and adenoid hypertrophy with secretory otitis media（OME） by using the A/N value of lateral radiograph of nasopharyngeal X-ray and EDQ-7 scale scores. Methods:Sixty cases of children with adenoid hypertrophy admitted from February 2019 to August 2021 were all underwent nasopharyngeal X-ray lateral radiographs to determine the adenoid/nasopharyngeal cavity ratio（A/N ratio） and then determine the size of adenoids. The Eustachian tube function ETDQ-7 survey was used to evaluate the patient\'s self-evaluation of the severity of the disease and ear symptoms, and the degree of influence were scored. Subsequently, the correlation between adenoid hypertrophy with OME and ETDQ-7 scores was statistically analyzed by using the Spearman rank correlation statistical method. Results:In adenoid hypertrophy with OME group, the ETDQ-7 scores of A/N≤0.60, A/N 0.61-0.70 and A/N≥0.71 were 4.15±1.75, 14.55±6.67 and 23.95±6.63, respectively. The higher the grade of adenoid hypertrophy, the higher the ETDQ-7 scores. In adenoid hypertrophy with OME group, the degree of adenoid hypertrophy was positively correlated with the ETDQ-7 scores（P<0.05）. Conclusion:Adenoid hypertrophy is also one of the potential factors causing OME in children.
目的：探讨鼻咽部数字化摄影及ETDQ-7量表评分在儿童腺样体肥大伴或不伴分泌性中耳炎（OME）的咽鼓管功能评估中的作用。 方法：对2019年2月—2021年8月收治的60例伴或不伴OME的腺样体肥大患儿采用鼻咽部数字化摄影，对鼻咽腔有效气道宽度（PAS）、鼻咽腔宽度及腺样体指数（腺样体厚度/鼻咽腔宽度，A/N）进行测量，采用咽鼓管功能ETDQ-7评分量表进行评分。对腺样体肥大伴OME与ETDQ-7评分的相关性进行统计学分析。 结果：腺样体肥大伴OME组A/N≤0.60、A/N 0.61-0.70、A/N≥0.71的ETDQ-7评分分别为4.15±1.75、14.55±6.67和23.95±6.63。腺样体肥大等级越高，ETDQ-7评分也越高。腺样体肥大伴OME组中，腺样体肥大程度与ETDQ-7评分呈正相关，差异有统计学意义（P<0.05）。 结论：腺样体肥大也是引起儿童OME的潜在因素之一。.

(1) Background: Inferior turbinates\' hypertrophy is often associated with Eustachian tube dysfunction (ETD); radiofrequency turbinate reduction (RTR) may provide a long-term improvement of nasal obstruction and ETD-related symptoms. (2) Aim: The study aimed to compare ETD in atopic and non-atopic patients before and after RTR and to investigate the correlation between tympanometry and Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7). (3) Methods: Ninety-seven patients, ranging from 33 to 68 years old, were screened by skin tests and divided into atopic (G1) and non-atopic (G2). Eustachian tube function (ETF) was evaluated through tympanometry, William\'s test and ETDQ-7. (4) Results: A moderate to severe subjective ETDQ-7 was found in the 35.42% of G1 and in the 22.45% of G2 patients before RTR. William\'s test resulted normal in 141 ears (72.68%), partially impaired in 15 (7.73%), and grossly impaired in 38 (19.59%) before surgery. A grossly ETD was evidenced in the 19.59% of cases before surgery and decreased to 6.18% after surgery with a significant difference among atopic patients (p < 0.001). (5) Conclusion: RTR may be considered a treatment option in patients suffering from ETD and inferior turbinates\' hypertrophy; RTR reduced the percentage of grossly impaired ET function (p < 0.001). ETDQ-7 and William\'s test may represent valuable tools to assess ET function before and after surgery.

OBJECTIVE: Testing olfaction should be an integral part of a clinical work-up in rhinosurgical procedures. Importantly, intact olfactory experience also includes retronasally perceived odors (retronasal olfaction). This study aimed at comprehensively assessing olfaction in patients undergoing rhinosurgical procedures in a comparative manner and evaluating relations to patient-reported outcome measurements (PROMs).
METHODS: Each nostril odor threshold and discrimination, and birhinal identification were tested using Sniffin\' Sticks in 14 subjects assigned for septoplasty (SP), 21 for septorhinoplasty (SRP), and 30 for endoscopic sinus surgery (ESS). The 27-Candy-Smell-Test was used to quantify retronasal abilities. Tests were repeated 3 months after surgery.
RESULTS: Olfactory dysfunction was preoperatively present in 21% of SP, in 47.6% of SRP, and in 80% of ESS patients. Odor threshold side differences were most frequently found in SRP. Frequently, SRP and ESS patients showed severely impaired retronasal olfaction. Half of included subjects re-visited after 3 months, but olfactory function did not improve overall and rarely on an individual basis to a meaningful extent. Subjective ratings on nasal patency and PROMs were not associated with olfaction nor with changes in olfactory scores.
CONCLUSIONS: Olfactory function can decisively be impaired a priori not only in patients awaiting sinus surgery, but also in those assigned for functional septorhinoplasty. This impairment may not improve in the short term, which has to be taken into account in patient counseling. This study adds to the current literature on olfaction in rhinosurgery with the extension of retronasal testing.

We assessed how eustachian tube dysfunction (ETD) changed with endoscopic sinus surgery (ESS) and identified factors associated with improvement.

Patients undergoing ESS for chronic rhinosinusitis with and without nasal polyposis (CRSwNP, CRSsNP) or recurrent acute rhinosinusitis (RARS) completed the Eustachian Tube Dysfunction Questionnaire 7 (ETDQ-7) preoperatively and postoperatively at 2 weeks, 6 weeks, 3 months, and 6 months. Included in analyses were demographics, comorbidities, Sinonasal Outcome Test 22 (SNOT-22), radiographic score, endoscopy score, procedure, and medication use. Regression analysis identified factors associated with improvement, defined as ΔETDQ-7 >3.5.
In total, 302 patients were studied. ETD prevalence was 68% in CRSsNP, 48% in CRSwNP, and 88% in RARS. Patients with ETD had a mean baseline ETDQ-7 of 25.8 ± 8.0 and improved postoperatively at 2 weeks (19.9 ± 8.1, P < .001), 6 weeks (17.8 ± 9.3, P < .001), 3 months (16.8 ± 8.5, P < .001), and 6 months (16.4 ± 7.9, P < .001). At 6 months, ETD improved in 89% of patients with CRSsNP, 68% with CRSwNP, and 78% with RARS. On multivariate analysis, ETD improvement was associated with higher preoperative ETDQ-7 score (adjusted odds ratio [aOR], 1.12; 95% confidence interval [CI], 1.04-1.22; P = .030), higher preoperative SNOT-22 score (aOR, 1.02; 95% CI, 1.02-1.08; P = .001), higher preoperative SNOT-22 ear subscore (aOR, 1.27; 95% CI, 1.02-1.65; P = .034), posterior ethmoidectomy (aOR, 1.59; 95% CI, 1.22-4.92; P = .025), and postoperative corticosteroid spray use (aOR, 1.57; 95% CI, 1.17-1.66; P = .008).
ETD symptoms often improve following ESS. Factors associated with improvement include higher preoperative disease burden, posterior ethmoidectomy, and postoperative corticosteroid spray.
