Purpose 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). Conclusion 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.

Objectives Currently, there is no consensus regarding the best protocol for diagnosing Eustachian tube dysfunction (ETD). We aimed to evaluate how patient characteristics affect tubomanometry (TMM) results. If an association between patient characteristics and TMM results exists, this should be considered in TMM interpretation. We also wanted to study if TMM correlates with other diagnostic tools of ETD. Methods A retrospective chart review was conducted on all patients with TMM results available from November 2011 to October 2020 at a tertiary referral center, including 432 ears from 219 patients. An association between diagnostic tests and patient characteristics was assessed using regression models. Spearman’s rank correlation was used to analyze correlations between diagnostic tests. Results None of the studied patient characteristics (age, gender, body mass index, smoking, sinonasal disease) was associated with TMM results except for pollen allergy (OR 1.74, 95% CI 1.15–2.63, P  = 0.009). TMM results correlated with Valsalva maneuver performance ( P  < 0.001, ρ  = 0.31) and otomicroscopic signs of inadequate middle ear ventilation ( P  < 0.001, ρ  = 0.28). The Eustachian tube dysfunction questionnaire-7 (ETDQ-7) score did not correlate with any diagnostic method. Conclusions TMM results are unaffected by patient characteristics other than pollen allergy. Thus, TMM may be used in ETD diagnostics in a wide variety of patients with straightforward interpretation. TMM correlates with other diagnostic tests studied but not with ETDQ-7. ETDQ-7 does not seem to correlate with other diagnostic tests and appears nonspecific in ETD diagnostics.

Background: Eustachian tube dysfunction (ETD) presents a complex diagnostic challenge in otolaryngology, compounded by its multifaceted nature and overlapping symptoms with chronic nasal disease. This article examines the intricacies of ETD diagnosis, emphasising the necessity for a consensus on diagnostic procedures. Methods: A review of the literature was performed through the OVID research tool in the Pubmed/Medline databases to identify relevant articles that discuss eustachian tube dysfunction diagnostics as well as its correlation with chronic nasal disease. Results: The literature review harvested 201 articles, and only 51 of them were included in the full text review. A consensus statement was identified on eustachian tube dysfunction, function and diagnostics. It appears that there is significant variability in the diagnostic tools used to identify eustachian tube dysfunction. The main diagnostic approaches used are tympanometry, tubomanometry and sonotubometry, combined with the Patient-Reported Outcome Measure ETDQ-7 questionnaire to support the diagnosis of the condition. Nasal pathology is mostly absent from the retrieved studies, while ear pathology is more commonly mentioned in the current literature. Conclusions: There is no gold standard diagnostic tool to determine the presence of eustachian tube dysfunction. Further discussion, large multicentre studies and focused research are required to achieve a consensus on a diagnostic approach. The authors suggest a diagnostic pathway that combines subjective and objective diagnostic tools to determine the presence of eustachian tube dysfunction. This pathway is simple and can be used in district ENT departments, highlighting the nasal pathology relevance to ETD.

Background Otitis media with effusion (OME) is a common disease in ear, nose, and throat clinics characterized by aural fullness and hearing loss and mainly caused by eustachian tube dysfunction (ETD). Tympanostomy tube insertion (TTI) is a conventional surgical treatment option that can alleviate symptoms but does not provide a definitive cure, and it is prone to recurrence. Balloon dilation eustachian tuboplasty (BDET) has become a novel procedure for the treatment of ETD, demonstrating significant potential in addressing the aforementioned limitations. However, it is not widely available in the clinic and few high-quality randomized clinical trials was conducted to investigate its long-term efficacy and security in OME. Therefore, the purpose of this study is to verify the efficacy of BDET combined with TTI for patients with OME and its prospects for providing a definitive cure. Methods and analysis This is a prospective, parallel-group, single-blind, randomized controlled prospective trial. Totally 124 patients with OME will be randomized into either group A or B. Group A will receive conventional therapy (TTI) while group B will use BDET therapy in addition to TTI. Outcome assessments will take place at baseline and at the 3rd, 6th, 12th, and 24th months after surgery. The primary outcome is eustachian tube function, which will be measured by the eustachian tube dysfunction questionnaire (ETDQ-7) and eustachian tube score (ETS). The secondary outcomes include middle ear function, hearing situation, and quality of life, which will be measured by acoustic impedance measurement, pure-tone audiometry, and Chinese-version Chronic Ear Survey (CCES). The main analysis of change in the outcomes will use mixed-model with repeated measures (MMRM) analyses of variance (ANOVAs). Discussion This is the first prospective trial in Chinese populations that aims to validate the long-term efficacy and safety of BDET-combined TTI therapy in patients with OME. This parallel-group, single-blind, randomized controlled trial may provide an opportunity to decrease the recurrence rate of OME and explore a definitive cure for patients with OME. This trial’s rigorous design enhances the reliability of the findings, ensuring a robust answer to the research question. In the future, the research team will further expand upon the clinical evidence and applications of the BDET combined therapy. Trial registration Chinese Clinical Trial Registry ChiCTR2400079632.

Background: Eustachian Tube Dysfunction (ETD) presents significant diagnostic challenges, particularly in patients with chronic nasal disease, which often mimic or complicate ETD symptoms. Tubomanometry (TMM) is emerging as an objective tool for diagnosing ETD, but its application in patients with concurrent nasal pathologies remains underexplored. Methods: One hundred patients with concurrent ETD and chronic nasal disease were recruited. They were categorized into three groups: chronic rhinitis (35 patients, group A), nasal septal deviation (31 patients, group B) and chronic rhinosinusitis with polyps (34 patients, group C). Treatments included nasal irrigation, septoplasty, and nasal polypectomy with functional endoscopic sinus surgery, respectively. The TMM parameters (R, C2 and C2–C1 scores) were assessed before and after interventions. The patient reported outcome measures (ETDQ-7 and NOSE scores) were also recorded and statistically correlated with TMM measures. Results: Group A showed improvements in R, C2 and C2–C1 scores and mild post-treatment reductions in ETDQ-7 and NOSE scores. Similar improvements were observed in Group B, with significant symptom reduction post-septoplasty, particularly on the side of the nasal septal deviation. Group C demonstrated the greatest improvement, with significant improvements in TMM values and substantial reductions in both ETDQ-7 and NOSE scores. The statistical results revealed correlations between the treatment of nasal pathologies and ETDQ-7 and NOSE scores. Conclusions: All TMM parameters improved in each group following the nasal intervention. This study highlights the utility of TMM in evaluating ETD in the context of chronic nasal disease and suggests that treating underlying nasal conditions can significantly alleviate ETD symptoms.

Purpose Tubomanometry (TMM) and the seven-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) was integrated to establish the Tubomanometry Eustachian Tube Dysfunction Questionnaire (T-ETDQ), and its reliability, potential clinical application, and diagnostic value for Eustachian tube function were investigated. Methods This prospective diagnostic study included patients visiting the ENT Department of our Hospital, between April and June 2021. Patients were grouped into Eustachian tube dysfunction (ETD) and control groups according to tympanometry diagnosis results. The diagnostic value of the T-ETDQ was evaluated using receiver-operating characteristic (ROC) curve analysis. Results There were 48 patients with Obstructive ETD and 24 patients without. The area under the ROC curve (AUC) of T-ETDQ was 0.898 (95% confidence interval [CI] 0.826–0.969), and the highest sensitivity and specificity were 76.7% and 86.7% respectively when the positive cutoff value was 4.72. The AUC of Eustachian tube score (ETS) was 0.731 (95% CI 0.625–0.837) and the highest sensitivity and specificity were 48.3% and 90.0% respectively when the positive cut-off value was 4.5. The ETS and T-ETDQ had kappa values of 0.311 and 0.585, respectively ( P  < 0.001 for both), showing both methods were comparable to tympanometry; however, T-ETDQ had more consistent results than ETS. Conclusion T-ETDQ can effectively quantify and evaluate ETD severity in adults, has a higher diagnostic value than ETS, making it a suitable diagnostic tool.

Purpose Aural fullness is a common symptom of middle ear diseases, most importantly Eustachian tube dysfunction (ETD). Yet, aural fullness may also be caused by inner ear disorders, such as hydropic ear diseases. Here, we report our experience with endolymphatic hydrops (EH) mimicking ETD. Furthermore, we review the literature related to (i) EH as a differential diagnosis of symptoms suggesting ETD and (ii) the pathophysiology and treatment of aural fullness due to inner ear disorders. Methods We retrospectively included adult patients with aural fullness as chief complaint and radiographically diagnosed EH. Hearing and Eustachian tube function were assessed using audiometry, tympanometry, and tubomanometry. Primarily suspected ETD was treated by balloon dilatation of the Eustachian tube (BDET). The endolymphatic space of the inner ear was imaged using gadolinium-enhanced MRI (Gd-MRI) including a 3D-real inversion-recovery sequence after intravenous gadolinium administration. Results We report three affected ears of two patients (two females, age 42 and age 51) with aural fullness as chief complaint. Audiometry of main speech frequencies was normal in all affected ears. In one ear, there was a type A tympanogram and in two ears, there was a type B tympanogram. In both patients, medical treatment for ETD and BDET were unsuccessful. Gd-MRI of the inner ears revealed cochlear EH in 3/3 ears affected by aural fullness, but not in the unaffected ear. Conclusion EH may underlay cases with aural fullness and could in these cases explain unsuccessful treatment for ETD. As ETD is often treated by invasive procedures, distinguishing ETD from EH as the underlying cause of aural fullness is important. Our findings raise the question whether Gd-MRI to rule out EH is indicated in patients with unexplained aural fullness, in particular after unsuccessful interventional treatment for ETD.

Background/objectives: Eustachian tube dysfunction (ETD) presents complex diagnostic challenges in otolaryngology, compounded by concurrent chronic nasal disease. Patient-reported outcome measures (PROMs) often assess ETD severity due to its elusive diagnosis. Tubomanometry (TMM) emerges as a promising diagnostic tool, yet its application alongside chronic nasal disease remains unclear. Our study aims to elucidate TMM’s role in ETD diagnosis within the context of chronic nasal diseases, integrating subjective assessments, clinical examination, and TMM results. Methods: A prospective observational study was conducted with patients suffering from ETD and chronic nasal disease allocated in three different groups according to their nasal pathology. Clinical examination, PROMs in the form of ETDQ-7, and NOSE questionnaires as well as TMM were performed. Results of the above subjective and objective measurements were analysed and correlated statistically to determine the value of TMM in chronic nasal disease patients. Results: All recruited patients suffered from ETD and chronic nasal disease, with similarly affected ETDQ-7 scores across all groups, while NOSE scores differed significantly based on the underground nasal pathology. TMM values confirm the presence of ETD in all three groups, confirming the role of TMM within this cohort. Interestingly, TMM values can still confirm the presence of ETD in patients with chronic nasal disease but cannot discriminate among chronic nasal pathology patients, making TMM a diagnostic tool with uniformity among the chronic nasal pathologies. Conclusions: ETD in individuals with chronic nasal disease presents distinct complexities, requiring a tailored diagnostic approach. In this context, a thorough clinical assessment, integrating ETDQ-7 and NOSE questionnaires, supplemented by TMM where accessible, is crucial to confirm diagnosis. This study confirms that TMM can diagnose ETD in all nasal pathology patients without being influenced by the nature of the disease. This research endeavours to refine diagnostic strategies, enriching clinical decision-making, and enhancing ETD management in patients suffering with chronic nasal diseases.

Objective This study aimed to clarify the role and safety of balloon eustachian tuboplasty (BET) in the treatment of otitis media with effusion (OME) in children. Methods This retrospective study was performed between January 2017 and February 2018. The study covered 25 OME patients treated with BET combined with myringotomy and tube insertion (MTI), designated as the BET group, and 24 OME patients treated with MTI during the same period considered as the controls. In addition, all patients received adenoidectomy if found with adenoid hypertrophy. The air–bone conduction gap (ABG) and curative effect were compared between the two groups. Tubomanometry (TMM) results were recorded preoperatively to confirm existence of eustachian tube dysfunction (ETD). Otologic history and examination results of all patients were carefully recorded before the operation, at 6, 12 and 18 months postoperatively. Results Six months after surgery, ABG difference between the two groups was less than 1 dB HL. At 12 months after the operation, ABG in the BET group was smaller than that in the control group. There was a marked ABG deterioration (from 10.1 to 15.9 dB HL) in the control group compared to that in BET. Statistically significant differences in ABG difference between the two groups were observed 18 months after surgery with cured and total effective rates of BET at 76.1 and 93.5%, respectively. In the control group, these rates were 60.9 and 89.1% respectively. No serious complications and tympanic perforations were found in all subjects. Conclusion MTI combined with BET is effective and safe in the treatment of children with OME. Compared to simple MTI, application of BET can effectively extend improvement period and increase cured rate, especially after removal of the ventilation tube. Directly benefit from the ventilation tube, the curative effect was close during the period of tube retention. Considering the sample size and follow-up time of this study, related studies targeting large cohorts are needed in the future to validate the benefits of BET in children with OME.

Endonasal ballon dilatation of the Eustachian tube (BET) is a promising treatment for Eustachian tube dysfunction with encouraging results over the last years in adults. In addition, in children, single studies demonstrated promising results, but revealed the necessity for broader and additional studies. Our retrospective analysis presents outcomes with BET in children with chronic obstructive dysfunction of the Eustachian tube, showing resistance to the conventional therapy after adenotomy with paracentesis or grommets (ventilation tubes). The data of 52 children, having undergone BET from April 2011 to April 2016, were retrospectively evaluated. Most children in our study presented middle ear effusion (47%), adhesive (21%), chronic otitis media (13%), or recurrent acute otitis media (11%). In 24 (37%) children, we combined BET with a paracentesis, in 5 (8%) patients with a tympanoplasty type I and in 3 (5%) patients with a type III. All children were assessed using an audiogram, tympanometry, and tubomanometry (50 mbar) before and after BET. In addition, we evaluated the results of the Lübecker questionnaire, which we performed before and after BET. The childrens’ ear-related and quality of life-related symptoms, such as pressure equalization, ear pressure, hearing loss, pain and limitation in daily life, and satisfaction pre- and postoperatively, were analyzed. In the majority of patients, we could see an improvement in the ear pressure, hearing loss, limitation in daily life, and satisfaction with recurrent inflammations, underlined by better outcomes in the tubomanometry and the tympanogram. BET in children is a safe, efficient, and promising method to treat chronic tube dysfunction, especially as a second line treatment, when adenotomy, paracentesis, or grommets failed before.
