7-item Eustachian Tube Dysfunction Questionnaire Research Articles

Symptom Localization May Differentiate Subtypes of Eustachian Tube Dysfunction.

To evaluate the predictive ability of symptom self-localization to distinguish obstructive eustachian tube dysfunction from non-obstructive salpingitis. Adult (age ≥18 years) patients with a primary complaint of aural discomfort who underwent diagnostic nasal endoscopy and tympanometry at a tertiary academic center were enrolled. Symptoms were self-localized by using a single finger on the affected side. All patients completed the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) and underwent scoring of eustachian tube inflammation using the Endoscopic Evaluation of the Eustachian Tube (3ET) system. Seventy-three patients were included in the study. Symptoms were localized to the external auditory canal (EAC) in 28 (38.4%), to the infratemporal fossa (ITF) below the lobule in 37 (50.7%), and to the preauricular region in 8 (11.0%). Demographics and medical history were similar between groups. The EAC group had significantly more negative tympanometric peak pressure (TPP) (median, -92.0 daPa; IQR, 95.5) and higher 3ET scores. In contrast, the ITF group had normal TPP (median, -2.0 daPa; IQR, 7.0) and higher 3ET scores. The preauricular group was more likely to have temporomandibular joint or pterygoid muscle pain. ETDQ-7 scores did not differ significantly between groups. Symptom localization is associated with specific objective findings in the evaluation of aural discomfort. Patients with pain localizing to the ITF are more likely to have findings of eustachian tube salpingitis without obstruction whereas patients with symptoms deep in the EAC are more likely to have findings consistent with obstructive eustachian tube dysfunction. 3 Laryngoscope, 133:1818-1823, 2023.

Characteristics of tympanogram in symptomatic Eustachian tube dysfunction.

To identify the characteristics of tympanogram in symptomatic Eustachian tube dysfunction (SETD) patients. 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. 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. 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.

Clinical outcomes of Eustachian tube dysfunction in chronic rhinosinusitis following endoscopic sinus surgery.

The effects of endoscopic sinus surgery (ESS) on the symptom burden of Eustachian tube dysfunction (ETD) in chronic rhinosinusitis (CRS) patients were investigated. Ninety-two patients with CRS following ESS were prospectively enrolled and followed up every 3 months for 1 year. The 7-item ETD Questionnaire (ETDQ-7) and 22-item Sino-Nasal Outcome Test (SNOT-22) were administered before ESS and at each visit following ESS. Before surgery, 25% of patients reported ETDQ-7 scores ≥ 14.5, indicating the presence of ETD. The mean preoperative ETDQ-7 and SNOT-22 scores were 13.3 and 40.0, respectively. The mean ETDQ-7 and SNOT-22 scores were significantly decreased to 8.2 and 17.0 at 1 year following ESS, respectively. Most patients reported alleviation of their symptoms within the first 3 months, and the prevalence of ETD had decreased to 3.3% at 1 year. Patients who received revision surgery had higher ETDQ-7 scores during the follow-up period. Additionally, 5.4% of patients reported worsening of their symptoms. ETD symptoms can be effectively alleviated in most patients within 3 months following ESS. However, 5.4% of patients reported worsening of their symptoms at the 1-year follow-up. Additional objective studies should be conducted to evaluate Eustachian tube function thoroughly in CRS patients.

Balloon dilation of the Eustachian tube with a seeker-based device: A registry of 169 patients.

ObjectiveTo collect real‐world data on the safety and effectiveness of balloon dilation of the Eustachian tube using a seeker‐based device in patients with persistent/chronic symptoms of Eustachian tube dysfunction.MethodsA multicenter, prospective, single‐arm registry was conducted from June 2018 through August 2020 at 10 US centers, including tertiary care and private practices. Primary endpoints included mean change from baseline in the 7‐item Eustachian Tube Dysfunction Questionnaire (ETDQ‐7) and the serious related adverse event rate. Secondary endpoints include changes in middle ear assessments, surgical intervention rate, and changes in Sino‐Nasal Outcome Test and Work and Activity Impairment (WPAI) questionnaires.ResultsA total of 169 participants were treated with balloon dilation of the Eustachian tube, with 166 and 154 participants completing the 6‐week and 6‐month follow‐ups, respectively. Repeated measures analysis of the change in ETDQ‐7 scores indicated statistically significant improvement (−2.1; 95% CI −2.40, −1.84; P < .0001) at 6‐month follow‐up. The minimum clinically important difference of improvement was achieved by 85% of participants at 6 months. Four nonserious adverse events were reported. Middle ear functional assessments were improved in the majority of participants with abnormal baseline findings. There were no statistically significant differences in the change from baseline ETDQ‐7 scores between participants who had concurrent procedures and those who did not. WPAI scores demonstrated significant improvement.ConclusionReal‐world evidence supports the clinical studies demonstrating that balloon dilation of the Eustachian tube with a seeker‐based device is a safe and effective procedure to treat ETD symptoms.Level of evidence3

Association of a standardized measure of nasopharyngeal inflammation with Eustachian tube dysfunction questionnaire score.

Standardized diagnostic criteria for Eustachian tube (ET) dysfunction (ETD) have not been established. The purpose of this study was to characterize the relationship between ET inflammation and ETD symptoms and to determine the diagnostic performance of a quantitative score. Patients were enrolled in a rhinology clinic between October 2018 and June 2019. Patients underwent nasal endoscopy and completed the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7). Nasopharyngeal inflammation identified on endoscopy was quantified using the Endoscopic Evaluation of the Eustachian Tube (3ET) score. Tympanometry was performed as indicated. Comorbid conditions were assigned during the patient encounter. A total of 414 patients were included in the study. Patients with clinically significant ETD symptoms (ETDQ-7 ≥2.1) had higher 3ET scores than those without symptoms. A 1-point increase in 3ET score was associated with a 1.7-fold increase in odds of clinically significant ETD symptoms (adjusted OR [aOR], 1.72; 95% CI, 1.46 to 2.05). The 3ET scores were correlated with ETDQ-7 scores (ρ=0.54) and 22-item Sino-Nasal Outcome Test (SNOT-22) scores (ρ=0.52). 3ET scores were not associated with tympanometric peak pressures. Patients with ETD symptoms were more likely to have laryngopharyngeal reflux (aOR, 2.71; 95% CI, 1.24 to 6.18). A 3ET score of 4 predicted symptomatic state in 80% of cases with a specificity of 97.8% and positive predictive value of 96.6%. Inflammatory findings at the nasopharyngeal ET orifice are associated with clinically significant ETD symptoms. The 3ET score is specific for a symptomatic state and has potential clinical utility in the evaluation of suspected ETD. ©2021 ARSAAOA, LLC.

Combined Endoscopic Sinus Surgery and Eustachian Tube Balloon dilatation improves Eustachian Tube Functions in patients had Chronic rhinosinusitis with nasal polyposis and Eustachian tube dysfunction

Background: Chronic rhinosinusitis [CRS] is a distressing disease that affects patients' mental and physical health. Eustachian tube dysfunction [ETD] affects approximately 1% of the adult population, especially patients with rhinosinus diseases. Transnasal Balloon Eustachian tuboplasty [BET] is a safe intervention for adult patients with chronic ETD. Aim of the work: To evaluate the impact of combined Function endoscopic sinus surgery [FESS] for CRS and BET on ETD manifestations compared to FESS only. Patients and Methods: 45 patients were randomly allocated into Group C underwent FESS, and Group-I underwent FESS and BET. ETD was evaluated using the 7-item Eustachian Tube Dysfunction Questionnaire [ETDQ-7] score, Otoscopy, Valsalva maneuver, and tympanometry. BET was performed using the XprESS ENT Dilation System with balloon inflation to 12 atmospheres for 2-min. Study outcomes were determined after 6-wk. Results: At 6-wk, the frequency of normal TM position and positive Valsalva's maneuver was significantly higher, and ETDQ-7 scores were significantly improved in all patients, while the frequency of tympanogram type-A was significantly and non-significantly higher in groups I and C, respectively. ROC curve and Regression analyses defined the application of FESS with BET as the significant predictor for normalization of tympanogram to type-A. Conclusion: Coupling Balloon Eustachian tuboplasty with Function endoscopic sinus surgery provided outcome more superior to Function endoscopic sinus surgery alone. Balloon Eustachian tuboplasty in experienced hands can be performed with a 100% technical success rate

Interpretation of Normal and Abnormal Tympanogram Findings in Eustachian Tube Dysfunction.

To characterize the relationship between objective tympanogram values and patient-reported symptoms and associations with common comorbid conditions. Cross-sectional study with prospective data collection. Tertiary medical center. Patients undergoing routine audiometric evaluation between October 2018 and June 2019 were included. Participants with temporomandibular joint dysfunction, inner ear hydrops, and similar conditions were excluded. Symptoms were assessed with the 7-item Eustachian Tube Dysfunction Questionnaire. Demographics and medical comorbidities were recorded from the medical record. Analysis of tympanometric peak pressure (TPP), demographics, and comorbidities was performed to determine associations with clinically significant eustachian tube dysfunction (ETD) symptoms. A total of 250 patients were included with similar demographics: 101 (40.4%) in the asymptomatic group and 149 (59.6%) in the symptomatic group. The median (interquartile range) TPP was -10 (20) daPa and -25 (100) daPa in the asymptomatic and symptomatic groups, respectively. A diagnosis of rhinitis was more likely to be associated with significant ETD symptoms (adjusted odds ratio, 2.61; 95% CI, 1.23-5.63). A subgroup analysis revealed that symptomatic patients with normal TPP values were negatively skewed as compared with asymptomatic patients. This symptomatic group had a higher prevalence of rhinitis and chronic rhinosinusitis than the asymptomatic group. Patients with symptoms of ETD may have a TPP within a range typically considered normal per conventional standards. This suggests that the currently accepted interpretation of tympanometry findings may be insensitive for the diagnosis of less severe cases of ETD.

Eustachian Tube Balloon Dilation: A Systematic Review and Meta-analysis of Treatment Outcomes.

To examine the effectiveness of eustachian tube balloon dilation for the treatment of eustachian tube dysfunction. PubMed, Scopus, and Google Scholar. A systematic review of eustachian tube balloon dilation for the treatment of eustachian tube dysfunction was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines to identify randomized control trials and prospective and retrospective studies published prior to January 31, 2019. Meta-analysis of proportions evaluated 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ7) scores, tympanometry, otoscopy findings, and the ability to perform a Valsalva maneuver. The systematic review identified 35 studies. Twelve studies met inclusion for meta-analysis (448 patients). Mean ETDQ7 scores decreased by 2.13 from baseline to 6 weeks (95% CI, -3.02 to -1.24; P < .001). From baseline to 6 weeks, 53.0% of patients had improvement in tympanograms (P < .001). At the long-term point (3-12 months), 50.5% of patients had improved tympanograms from baseline (P < .001). There was no significant difference in the proportion of improved tympanograms at 6 weeks compared to long term (P = .535). Normal otoscopy exams at baseline increased by 30.0% at 6 weeks (P < .001) and 55.4% in the long term (P < .001). There was a 67.8% increase in proportion of patients able to perform a Valsalva maneuver in the long term compared to baseline (P < .001). Eustachian tube balloon dilation appears to be associated with improvement in subjective and objective treatment outcome metrics. The improvement appears stable at 3 to 12 months after dilation. Patients with eustachian tube dysfunction are likely to benefit from balloon dilation, particularly those with medication-refractory disease.

Navigation-Assisted Balloon Eustachian Tuboplasty for Eustachian Tube Dilatory Dysfunction.

Objectives.Balloon Eustachian tuboplasty (BET) is a novel treatment method for Eustachian tube dilatory dysfunction (ETD). However, surgeons cannot identify the insertion depth of the catheter during BET, resulting in potential risks such as internal carotid artery (ICA) injury. Therefore, we developed an image-guided navigation balloon catheter to identify the insertion depth of the catheter and to establish awareness of the proximity of the ICA. This study aimed to evaluate the technical feasibility of this image-guided navigation balloon catheter system in patients with ETD.Methods.Twenty-nine patients (38 ears; nine bilateral; 21 right ears, and 17 left ears) diagnosed with ETD were assessed. All patients who showed no improvement despite medical therapy with topical steroids, anti-reflux medication, and the Valsalva maneuver for a minimum of 6 weeks received image-guided navigation-assisted BET. The 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) score and Valsalva maneuver were used to evaluate patients’ symptoms preoperatively and at the postoperative follow-up.Results.Image-guided navigation-assisted BET was safely performed in all patients. The mean total ETDQ-7 score was 25.4±7.1 preoperatively, 17.5±6.2 at 1 month, and 15.2±7.0 at 6 months (P<0.001). In total, a Valsalva maneuver was possible for 28 of 38 ears (73.7%) at the time of the patient’s final visit at 6 months post-procedure.Conclusion.Image-guided navigation balloon catheters are a potentially valuable tool in patients with ETD. Their use is also technically feasible and safe when performing BET to treat ETD.

Eustachian Tube Quality of Life and Severity of Disease in Patients With Chronic Rhinosinusitis.

Chronic rhinosinusitis (CRS) has long been a suspected risk factor for Eustachian tube dysfunction (ETD). However, there have been few studies quantifying the presence of ETD in CRS patients. We sought to determine the prevalence of ETD symptoms in patients undergoing functional endoscopic sinus surgery (FESS) for CRS using the validated 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) and to correlate the ETDQ-7 scores with scores of CRS symptom severity based on the 22-item Sino-Nasal Outcome Test (SNOT-22). Patients for FESS were preoperatively administered both the ETDQ-7 and the SNOT-22 validated quality of life instruments. Pearson and Spearman correlation coefficients were calculated. Changes in ETDQ-7 were measured at 3 months and differences were compared via paired t test. A total of 82 patients completed the surveys. Thirty-nine (47.6%) patients had ETDQ-7 score ≥14.5, signifying clinically significant ETD symptoms. The mean ETDQ-7 score of the study population was 15.8 ± 8.8, and the mean SNOT-22 score was 37.5 ± 19.7. The Pearson and Spearman correlation coefficients between ETDQ-7 and the total SNOT-22 score were 0.52 (P > .0001) and 0.51 (P < .0001), respectively. There was significant improvement in ETDQ-7 scores postoperatively. While the association between ETD and CRS has long been known, this is one of the few prospective patient studies evaluating otologic symptoms in a CRS population. We found that a significant percentage of CRS patients suffer from ETD symptoms based on patient-reported subjective outcome measures. This study demonstrates that otologic symptoms increase with CRS severity and improve after FESS.

Translation and Validation of the "7-Item Eustachian Tube Dysfunction Questionnaire" to European Portuguese (PT).

Eustachian tube dysfunction is a common cause of morbidity in both adults and children, associated with nasal andotologic symptoms. Symptomatic evaluation is very important for the correct diagnosis and evaluation of the treatment efficacy of thisentity. The "7-item Eustachian Tube Dysfunction Questionnaire" was described and validated by McCoul et al and proved to be a usefultool, easy to apply, with good validity in the evaluation of eustachian tube dysfunction symptoms. This study presents the validationprocess of the European Portuguese version of the "7-item Eustachian Tube Dysfunction Questionnaire". The aim of this study was totranslate and validate the European Portuguese version of "Eustachian Tube Dysfunction Questionnaire-7". The "7-item Eustachian Tube Dysfunction Questionnaire" was adapted and translated to European Portugueseusing standard validation methodology. The European Portuguese version of "7-item Eustachian Tube Dysfunction Questionnaire"was completed by a group of 50 consecutive adult patients diagnosed with eustachian tube dysfunction and 25 healthy patients whoserved as a control group. All respondents in the Eustachian tube dysfunction group repeated the "7-item Eustachian Tube DysfunctionQuestionnaire" in a two week-period. Statistical analysis was performed to determine its psychometric properties (reliability -internalconsistency and test-retest reproducibility, and discriminant validity). Face and content validity were confirmed, and reliability testing revealed similar internal consistency for the entire instrumentas the original questionnaire, and strong correlation between individual items and total score. The questionnaire was easy and quickto administer. Test-retest reliability of the European Portuguese version was adequate, with excellent intraclass correlation coefficientsand without significant differences between the total score from the first and second evaluations. Discriminative validity was confirmedby statistically significant differences between scores of the test and control groups. This study presents the European Portuguese version of the "7-item Eustachian Tube Dysfunction Questionnaire" questionnaire,an adapted, validated and well-accepted instrument to evaluate the symptoms of eustachian tube dysfunction in the EuropeanPortuguese speaking population. The European Portuguese version of the "7-item Eustachian Tube Dysfunction Questionnaire" is recommended as aroutine procedure in the assessment of patients with eustachian tube dysfunction in the European Portuguese speaking populationand for the evaluation of treatment outcome.

Long-term Outcomes of Balloon Dilation for Persistent Eustachian Tube Dysfunction.

To gather long-term follow-up data on the efficacy of balloon dilation for treating patients with persistent Eustachian tube dysfunction (ETD). Extended follow-up study of the treatment arm of a prospective, multicenter, randomized controlled trial. Tertiary care academic center and private practice. Patients diagnosed with medically refractory persistent ETD. Balloon dilation of the Eustachian tube. The endpoints were the mean change from baseline in the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) score, revision dilation rate, changes in assessments of middle ear function, and patient satisfaction. A total of 47 participants enrolled in the extended follow-up study. Mean follow-up was 29.4 months (range, 18-42 mo). There was a statistically significant mean (SD) change from baseline in the overall ETDQ-7 score (-2.5 ± 1.2; p < 0.0001). A reduction of one or more in their overall ETDQ-7 score was observed by 93.6% (44/47) participants. The revision dilation rate was 2.1% (1/47). Among participants with abnormal baseline middle ear assessments, 76.0% had normalized tympanic membrane position (p < 0.0001), 62.5% had normalization of tympanogram type (p < 0.001), and 66.7% had positive Valsalva maneuvers (p < 0.0001). Participant satisfaction was 83.0% at long-term follow-up. Balloon dilation results in durable improvements in symptoms and middle ear assessments for patients with persistent Eustachian tube dysfunction at mean follow-up of longer than 2 years.

Measuring the health utility of chronic eustachian tube dysfunction.

To assess the health utility of chronic Eustachian tube dysfunction (ETD). This is a prospective study of 53 patients with chronic ETD recruited from a tertiary clinic from April 2017 to July 2018. The 7-Item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) was administered, and health utility was evaluated using the EuroQol-5 Dimensions-3 Level Instrument (EQ-5D-3L), the visual analogue scale (VAS), time tradeoff (TTO), and standard gamble (SG). Participants were grouped into medical or procedural management groups. One-week follow-up included repeated health utility measures and ETDQ-7. Fifty-three patients were included in the final analysis. Of those, 34 were managed medically, and 19 received myringotomies ± PE tubes. The mean baseline ETDQ-7 was 4.26 ± 1.31; whereas health utility measures were different depending on the method utilized: EQ-5D-3L 0.90 ± 0.11; VAS 0.76 ± 0.21; TTO 0.85 ± 0.23; and SG 0.94 ± 0.11 (P < .001). There was a significant change in ETDQ-7 (P = .001) and TTO (P = .011) scores posttreatment. On the ETDQ-7, question 2 (pain in the ears) was significantly associated with VAS (P = .032), and question 4 (ear symptoms during a cold or sinusitis) was significantly associated with TTO (P = .006). Chronic ETD has a significant burden on quality of life, with a health utility similar to gastroesophageal reflux disease and moderate asthma. Although treatment-related changes are measurable using disease-specific quality-of-life measures, only TTO was significantly changed after treatment. Health utility seemed to depend on the method of measurement but provided a benchmark for evaluating cost-effectiveness of innovations to manage ETD. 2 Laryngoscope, 130:E39-E44, 2020.

A Randomized Controlled Trial of Balloon Dilation as a Treatment for Persistent Eustachian Tube Dysfunction With 1-Year Follow-Up

Objective:Compare Eustachian tube balloon dilation versus continued medical therapy (control) for treating persistent Eustachian tube dysfunction (ETD).Study Design:Prospective, multicenter, randomized controlled trial.Setting:Tertiary care academic center and private practice.Patients:Diagnosed with medically refractory persistent ETD.Interventions:1:1 Randomization to balloon dilation or control. After 6 weeks, control participants had the option to undergo balloon dilation if symptoms persisted.Main Outcome Measures:Primary efficacy endpoint was the comparison between treatment arms in the mean change from baseline in the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) score. Primary safety endpoint was complication rate.Results:Sixty participants were randomized (31 balloon dilation, 29 control). Mean (SD) change in overall ETDQ-7 score at 6 weeks was −2.9 (1.4) for balloon dilation compared with −0.6 (1.0) for control: balloon dilation was superior to control (p < 0.0001). No complications were reported in either study arm. Among participants with abnormal baseline assessments, improvements in tympanogram type (p < 0.006) and tympanic membrane position (p < 0.001) were significantly better for balloon dilation than control. Technical success was 100% (91 successful dilations/91 attempts) and most procedures (72%) were completed in the office under local anesthesia. Improvements in the ETDQ-7 scores were maintained through 12 months after balloon dilation.Conclusions:Balloon dilation is a safe and effective treatment for persistent ETD. Based on improved ETDQ-7 scores, balloon dilation is superior to continued medical management for persistent ETD. Symptom improvement is durable through a minimum of 12 months. Procedures are well tolerated in the office setting under local anesthesia.

Fluoroscopy-guided balloon dilation in patients with Eustachian tube dysfunction.

To prospectively evaluate the technical feasibility and safety of fluoroscopy-guided balloon dilation in patients with Eustachian tube (ET) dysfunction. Patients who could not do a Valsalva manoeuvre for more than 6 months and diagnosed with chronic otitis media or ET dysfunction were prospectively enrolled. A 0.035-in. guide wire and 6-mm long balloon catheter with a diameter of 2 mm were used to dilate the cartilaginous portion of the ET under fluoroscopic guidance. The balloon was inflated by manual injection twice for 1 min each time. Clinical outcomes were assessed by the patient's ability to perform a Valsalva manoeuvre, and symptoms were assessed using the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) score. Balloon dilation was attempted in a total of ten adult patients from October 2016 to March 2017. Technical success was achieved in all procedures (10/10). Ninety percent (9/10) of the balloons were fully dilated without waist deformity. There were no major complications. All patients were able to perform a Valsalva manoeuvre at the time of their last visit and/or improvement of at least one ETDQ-7 score. Fluoroscopy-guided balloon dilation seems to be technically feasible and safe in the treatment of ET dysfunction. • Fluoroscopy-guided balloon dilation without general anaesthesia was well-tolerated in all patients. • Location of the balloon catheter can be monitored during the procedure. • Inflation state of the balloon catheter can be monitored during the procedure. • Using guide-wire during the procedure would prevent false passage creation. • All patients had clinical improvement within 3 months after balloon dilation.

Responsiveness of the 7-item Eustachian Tube Dysfunction Questionnaire.

Baro-challenge-induced Eustachian tube (ET) dysfunction is defined as the presence of aural discomfort, popping, or pain, which only arises in case of ambient pressure changes, without abnormalities on otoscopy or tympanometry. Our primary aim was to determine the discriminative power of the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) in patients with baro-challenge-induced ET dysfunction in comparison with that in healthy controls. The secondary aim was to determine the responsiveness of ETDQ-7 in patients with baro-challenge-induced obstructive ET dysfunction who underwent balloon dilation tuboplasty (BDET). The accuracy of the diagnostic test was determined on the basis of the area under the curve in receiver-operating curve (ROC) analysis. Responsiveness to change of ETDQ-7 was assessed by exploring preoperative and postoperative ETDQ-7 scores using Cohen's kappa coefficient. Patients were asked whether their complaints improved, remained stable, or deteriorated after BDET. The findings of subjective evaluation were then compared with the difference in the ETDQ-7 score after BDET. In the baro-challenge-induced ET dysfunction group, the median preoperative total ETDQ-7 score was 26, decreasing to 16 after BDET. ROC analysis demonstrated excellent discriminative power for the baro-challenge-induced ET dysfunction group. Cohen's kappa coefficient was 0.633, indicating that there was substantial agreement between the ETDQ-7 values before and after BDET. ETDQ-7 can discriminate between patients with baro-challenge-induced ET dysfunction and healthy controls and can therefore be useful in its diagnosis. Furthermore the ETDQ-7 is responsive to change in patients with baro-challenge-induced ET dysfunction who have undergone BDET, although a larger sample size is required to confirm these preliminary findings.

Eustachian tube balloon dilation surgery

Eustachian tube dysfunction (ETD) is a common condition without an effective, accepted treatment. Balloon dilation Eustachian tuboplasty (BDET) has been recently proposed for the management of ETD. Previous studies of Eustachian tube function and treatment have not included a validated assessment of patient symptoms. We report for the first time the outcomes of BDET using a validated disease-specific symptom score, the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7). Consecutive patients undergoing BDET were prospectively enrolled from an otolaryngology practice at a tertiary care medical center. Inclusion criteria were adults with a diagnosis of ETD based on symptoms and abnormal tympanogram. Patients with craniofacial abnormalities or active infection were excluded from study. Primary outcome measures included the ETDQ-7 score, tympanometry, and otoscopic appearance. Secondary measures included the 22-item Sinonasal Outcome Test (SNOT-22) score. Twenty-two consecutive patients underwent 35 BDET procedures. Significant postoperative improvement was seen in tympanometry and otoscopic appearance (p < 0.001). ETDQ-7 scores at 3 weeks, 6 weeks, 12 weeks, and 6 months postoperatively were significantly improved over baseline (p < 0.001). ETDQ-7 scores showed fair correlation with SNOT-22 scores (r > 0.65). ETDQ-7 change scores demonstrated good responsiveness and sensitivity to clinical change following BDET. BDET is an effective surgical intervention for the treatment of ETD in adults. Postoperative improvements were observed using objective and subjective measures. The ETDQ-7 is a valid, disease-specific instrument for the assessment of treatment outcomes and may be applied for clinical use in patients with ETD. Further study is necessary to determine long-term effectiveness.
