NCT05275686
Intranasal nasal steroid sprays are the mainstay of treatment for chronic Eustachian tube dysfunction despite having little supportive evidence in the literature. A novel, commercially available nasal spray delivery system is available now for fluticasone that improves its delivery to the nasopharynx. The hypothesis of this study is that fluticasone using the novel spray system is effective for Eustachian tube dysfunction (ETD).
NCT04404036
This study was originally designed with three aims: (1) healthy controls to assess nasal nitric oxide, (2) adults with Eustachian Tube Dysfunction (ETD), and (3) adults with facial pain/pressure. However, only the ETD cohort (Aim 2) was initiated and enrolled. During study conduct, additional symptom and pain assessments (including MPQ-SF and mBPI-sf) were collected in the ETD cohort for exploratory purposes. All results in this record reflect ETD cohort participants who used the SinuSonic device twice daily for 6 weeks.
NCT07200310
This study looks at whether working as a hot-air balloon pilot-being exposed to burner noise, changes in air pressure/temperature, and vertical acceleration-is linked to changes in hearing, Eustachian tube function, and vestibular (balance) function. Adult pilots from Cappadocia will be compared with adults who do not have these exposures. Approximately 90 participants are expected to be enrolled For contextual exposure information, representative in-field noise measurements during balloon operations and basic flight parameters may be documented Each participant will attend one visit (\~60 minutes) in an ENT/audiology laboratory. After a short questionnaire and an ear exam (otoscopy), the following non-invasive tests will be performed: tympanometry; tympanometry with simple maneuvers (Valsalva/Toynbee) to evaluate Eustachian tube function (ΔTPP); pure-tone audiometry (including extended high frequencies); otoacoustic emission tests (TEOAE and DPOAE); acoustic (stapedius) reflex thresholds; and a brief cervical vestibular evoked myogenic potential (cVEMP) test. Symptom-triggered questionnaires will also be used: for participants reporting tinnitus, the Tinnitus Handicap Inventory (THI); for those reporting dizziness, the Berg Balance Scale (BBS). No medications or blood tests are involved. Testing is safe and routinely used in clinical care. Risks are minimal (for example, temporary ear-canal pressure or brief dizziness). Testing will be stopped if any discomfort occurs. Personal information will be kept confidential, and results will be reported only in group form. Findings from this study may help improve occupational health guidance for hot-air balloon pilots.

adolescents are usually exposed to tobacco smoke passively. this can reduce their lung functions and negatively impact functions of Eustachian tube. The solution is to lower rates to tobacco exposure and use the support of Buteyko Breathing
NCT07122999
This randomized controlled trial evaluated the effectiveness of autoinflation in preventing recurrence of otitis media with effusion (OME) and reducing the need for reoperation after tympanostomy tube (TT) extrusion in children. Sixty-six pediatric patients with chronic OME underwent TT placement, and 54 were included in the final analysis. After TT extrusion, participants were randomized into two groups: an autoinflation group using a handheld device (Eustachi) for five weeks, and an observation-only group. Patients were followed for two years post-extrusion, with periodic otoscopic and tympanometric assessments. The autoinflation group showed a lower recurrence rate (19.2%) compared to the observation group (35.7%), although this difference was not statistically significant. However, the reoperation rate was significantly lower in the autoinflation group (7.7% vs. 28.6%). Tympanometric findings suggested more stable middle ear pressure in the autoinflation group. These results indicate that autoinflation is a safe, feasible, and non-invasive method that may support eustachian tube function and reduce the need for repeat TT placement in children following TT extrusion.

The Eustachian tube is a tube that connects the back of the nose with the ear. Its job is to keep the pressure on the inside of the eardrum close to the pressure outside the eardrum, so that the eardrum can vibrate properly. Usually this tube is closed, but it opens briefly during swallowing. In the condition called patulous eustachian tube, this tube is open all the time. This is a benign condition but it can be very bothersome to patients. The incidence of patulous Eustachian tube dysfunction is about 0.3-6.6% of the population. However, about 15% of the people who have this condition are bothered enough by it that they seek medical attention. This condition is more common in females than males and is more common in adults than children. Some of the common symptoms of patulous eustachian tube can include roaring tinnitus synchronous with nasal respiration, audible respiratory sounds, sensation of a plugged ear and fluctuating aural fullness. In most cases the cause is idiopathic. Some predisposing factors include weight loss, stress,anxiety,fatigue, pregnancy, and temporomandibular joint syndrome. It can also be caused by adhesions in the nasopharynx following surgery on the adenoids. Sometimes it can be associated with medications such as diuretics and oral contraceptives. Neuromuscular disorders that cause atrophy such as multiple sclerosis, stroke and motor neuron disease have also been postulated to cause patulous eustachian tube. The purpose of this trial is to learn more about the condition and help us learn about how the eardrum might be treated to prevent it vibrating with sounds or noises coming up the Eustachian tube. The first part of the study will consist of a questionnaire to help to further define the symptoms of patulous eustachian tube, and to measure how severe these symptoms are. Currently there are few treatments that are satisfactory for patients. Common surgical therapies include injections of various substances into the Eustachian tube opening including paraffin, Teflon,or gelfoam. Unfortunately, these methods are either temporary or have lead to serious complications including cerebral thrombosis and death (due to inadvertent injection into the carotid artery). Other treatments have focused on cauterizing the Eustachian tube opening but these have been either unsatisfactory or caused damage to the trigeminal nerve. Myringotomy and insertion of a ventilation tube has helped some patients but others have found that this increased the patient's discomfort. The investigators have been treating patients recently by placing some putty like clay material on the eardrum, which stops it vibrating so much with the patient's own voice, and this appears to be quite effective for many patients. It is also easily removed if the patient does not find it helpful. However, the investigators do not really have a good idea of exactly which patients are helped by this, and which are not, and just how much their symptoms are helped, as well as how long the treatment helps them for.
NCT05998356
To date, more than 130 000 Balloon Eustachian Tuboplasty (BET) procedures have been performed worldwide. This procedure is proposed in case of Obstructive Eustachian Tube Dysfunction (OETD) with or without chronic otitis media. However, the effectiveness of this procedure is still discussed amongst otolaryngologist. Most of studies,were open label prospective studies comparing Eustachian tube function before and after surgical treatment. A recent meta-analysis suggests that BET procedure improves postoperative Eustachian tube function, but high-level evidence is still lacking. In this project, the investigators propose to perform the first blinded randomized controlled trial procedure to assess the changes of Eustachian tube function after BET in a population of subjects with chronic OETD with or without chronic otitis. Prognosis factors of efficacy will be also investigated during the study.
NCT04645511
This study is a prospective, randomized, placebo-controlled, double-blinded clinical study. The balloon sinuplasty treatment is compared to placebo effect in chronic or recurrent maxillary sinusitis. The purpose is to find out the efficacy of balloon sinuplasty of maxillary sinuses and the patients who get the best benefit from balloon sinuplasty. The investigators also want to find out if balloon sinuplasty of maxillary sinuses improves Eustachian tube dysfunction. The study is executed in the Department of Ear and Oral Diseases, Tampere University Hospital. 120 patients who have either recurrent acute or chronic rhinosinusitis without nasal polyposis and whose sinusitis is limited mainly into maxillary sinuses, are recruited in the study. The patients are allocated either into the chronic maxillary sinusitis (60 patients) or the recurrent maxillary sinusitis (60 patients) branch of the study. Then, the patients are consecutively randomized into two treatment groups in the proportion of 1 to 1: A) Balloon sinuplasty group and B) Placebo group. The treatment is performed according to the patient's group status and all the patients are followed 12 months postoperatively. The effect of balloon sinuplasty treatment in chronic maxillary rhinosinusitis is going to be measured primarily with the Sino-Nasal Outcome Test (SNOT-22). In recurrent acute maxillary rhinosinusitis, the effect of balloon sinuplasty treatment will be measured primarily with the number of acute rhinosinusitis infections. Besides this, number of antibiotic treatments and sick leaves are inquired, Visual Analog Scale (VAS) and Eustachian Tube Dysfunction Questionnaire (ETDQ-7) are used, rhinomanometry, Cone Beam Computed Tomography (CBCT), tympanometry, tubomanometry, nasal endoscopy and general evaluation of the patients clinical ORL-status are performed. Also pre- and postoperative biopsies are taken from the middle turbinates.
NCT04776967
Eustachian tube dysfunction (ETD) and middle ear barotrauma (MEB) are common reported complications during hyperbaric oxygen treatment. The Phase I study data was the first to demonstrate a statistically significant decrease in the occurrence of symptomatic ETD and middle ear barotrauma (MEB). The Phase I Trial suggested the total time interval and rate (slope) of compression (ROC) may be a determining factor in ETD and MEB. This Phase II study investigates an optimal total time interval and rate of compression to reduce ETD and MEB when considering each multiplace treatment (with multiple patients) as the unit of observation collectively as a group, rather than for each individual patient. Data will be collected prospectively on group patient-treatment exposures. The investigators randomly assigned patient-treatment group exposures to four different time interval and rate (slope) of compression. These total time intervals of compression and rates (slopes) of compression are identical to those used in the Phase I trial. All patients experiencing symptoms of ETD and MEB requiring compression stops will be evaluated post treatment to confirm the presence of ETD and MEB using the O'Neill Grading System (OGS). Data will be analyzed using the IBM-SPSS statistical software program. The number of compression holds observed in each of the 4 compression schedules, similar to ther Phase I trial will be recorded. Patients who are symptomatic and require compression stops (as in the Phase I trial) using a United States Navy Treatment Table 9 (USN-TTN9) during elective hyperbaric oxygen treatments in a Class A multiplace hyperbaric chamber will be analyzed. Analysis using descriptive and inferential statistics will be applied to the patients requiring first stops in the 4 compression profiles. This Phase II study increases the sample size of treatments and they will be combined with the total number of treatments used in the original phase I study. This will increase power to facilitate detailed descriptive analysis and to determine if the findings are robust in the phase I study.
NCT03850197
The Eustachian tube (ET) is a biological tube that links the middle ear to the back of the nose and throat. It has several functions, of which the most important is to maintain optimal middle-ear health. Eustachian tube dysfunction (ETD) can result in pain or a popping sensation in the ears when flying in an airplane or going up a tall building in an elevator. Many people with ETD also suffer from ear problems such as repeated middle-ear infections or fluid in the ears. However, there are very few easily-administered tests to measure and assess Eustachian tube function (ETF). Tubomanometry is one of these tests, however it is expensive and used to measure ETF only in research settings. In this study, the investigators propose that using a combination of two readily available devices, the EarPopper and a tympanometer, will work in a manner similar to a Tubomanometer to test ET function.
NCT02631187
This is a study that aims to evaluate the feasibility of undertaking a United Kingdom (UK) multi-centre randomised controlled trial of BET for the treatment of moderate (grade 2 or 3) retraction pockets (RPs). This future study will aim to address the question: Does BET improve symptoms scores, audiometry and otoscopic appearance of Grade 2-3 pars tensa RPs in adult patients? Currently conservative treatments for this condition has been shown to be ineffective; there is a significant risk of progression to hearing loss or more serious complications in untreated retraction pockets; and the surgical treatments available to us in the UK not only have a number of risks and drawbacks, but also do not aim to treat the underlying cause (Eustachian Tube dysfunction (ETD)).
NCT01251432
This research study measures how well the Eustachian tube works and looks directly at the anatomy of the Eustachian tube in adults who have had tympanostomy tubes surgically inserted into their eardrums because they have been diagnosed as having either "otitis media" or "poor Eustachian tube function". The Eustachian tube is a biologic tube that connects the back of the nose to the middle ear (the airspace located behind your eardrum). That tube is usually closed, but can be opened by swallowing and other activities. Periodic openings of the Eustachian tube allow air to flow between the nose and middle ear which keeps the pressure of gas in the middle ear at the same level as that of the atmosphere, a condition required for good hearing. In children and adults, middle-ear diseases such as otitis media with effusion (the buildup of fluid within the middle ear) and a form of temporary hearing loss (conductive hearing loss) occur if the Eustachian tube does not open, does not open frequently enough or is always open (called a patulous Eustachian tube). A diagnosis of these different conditions can be made using standard, clinical tests of Eustachian tube function and the Eustachian tube can be visualized where it enters the back of the nose using a specialized telescope called an endoscope. Some scientific reports suggest that the cause of poor Eustachian tube function in an individual can be determined by studying the anatomy of the Eustachian tube at the back of the nose and the movements of the Eustachian tube in that area during swallowing, talking and other activities using an endoscope. In this study, the investigators plan to explore the relationship between the results of the standard Eustachian tube function tests and those for the anatomy and function of the Eustachian tube in adults with a disease condition likely to be caused by poor Eustachian tube function. Also, there are a number other disease conditions (examples: nasal allergy, acid reflux disease) that are related to poor Eustachian tube function and it is possible that these conditions and their effect on Eustachian tube function can be treated with medicines. Therefore, the investigators also plan to evaluate enrolled persons for those conditions. It is expected that if the results of the standard Eustachian tube function tests can be explained by the anatomy of the back of the nose and Eustachian tube, the functional anatomy (movements during swallowing etc) of the Eustachian tube or the presence of allergy and or/acid reflux disease, new medical and/or surgical treatments can be developed to improve Eustachian tube function and "cure" or treat the associated middle-ear diseases.
