Objective: Eustachian tube function is of central importance for the ventilation of the middle ear. A dysfunction can be associated with chronic otitis media, and cholesteatoma. Balloon Eustachian tube dilatation (BET) is a treatment option used to solve eustachian tube dysfunction. Although BET is widely performed, little is known about the occurrence rate of the complications associated with BET. The aim of the present study was to observe the rate of sensorineural hearing loss (SNHL) after BET.Methods: We retrospectively evaluated in a chart review 1,547 patients and 2,614 procedures of BET performed in a single center between 2015 and 2019 using the Spiggle and Theis, Overath, Germany eustachian tube dilatation system.Results: We observed seven cases of SNHL after BET. In two cases, the SNHL persisted, and in five cases, the SNHL was transient. In two cases of SNHL, a simultaneous tympanoplasty was performed. The overall rate of SNHL per procedure is 0.3%. The rate of permanent SNHL is 0.08%.Conclusion: BET has a low rate of SNHL. Rapid middle ear pressure changes are assumed to cause BET-related hearing loss.

AbstractObjectiveTo assess the effect of topical betahistine on Eustachian tube function in subjectively abnormal subjects in a hyperbaric chamber.MethodActive and passive Eustachian tube function was examined using tympanometry in a pressure chamber.ResultsActive Eustachian tube function was tested against the negative middle ear pressure induced by increasing the chamber pressure to +3 kPa. One voluntary swallow decreased middle-ear pressure by a mean of 1.36 kPa. Passive Eustachian tube function was tested by measuring spontaneous Eustachian tube openings as the chamber pressure dropped from +10 kPa to ambient. Four distinct patterns of Eustachian tube behaviour were seen, three of which indicated Eustachian tube dysfunction. Betahistine had no positive effect on Eustachian tube opening, although previous animal studies had suggested a beneficial effect.ConclusionTopical betahistine had no effect on Eustachian tube function. Combining a hyperbaric chamber with tympanometry proved ideal for evaluating Eustachian tube function.

Since the risk of sensorineural hearing loss from persistent chronic otitis media and mastoiditis is greater than the risk to loss of labyrinthine function from carefully performed surgery, it is felt that the best treatment for chronic suppurative middle ear disease in an only-hearing ear is surgical removal of disease. Between the years 1961 to 1970 14 cases of chronic otitis media and mastoiditis in only-hearing ears were treated surgically at the Massachusetts Eye and Ear Infirmary. Five cases presented with resistant foul otorrhea, while five patients presented with increasing hearing loss and four with vertigo. The patients with hearing loss and vertigo were subjected to surgery at the earliest possible date. Wide-field surgical exposure of the mastoid and middle ear spaces with thorough removal of diseased tissue was carried out. Particular attention to avoid injury to the labyrinth, either directly or indirectly, must be kept in mind and it is recommended that surgery in only-hearing ears be performed by only the most experienced and capable otologic surgeon. All 14 ears have remained dry after surgery. Hearing was significantly improved in ten cases, while two were unchanged and two were made worse, as regards the conductive loss only. In all 14 cases postoperative discrimination scores were normal, so that even those cases that did not achieve serviceable hearing levels from surgery were able to use amplification. The results in this series confirm the feeling that carefully performed and timed surgery is effective in controlling chronic suppurative disease, while preserving function in only-hearing ears.

The present study includes evaluation 60 ears of 30 nasal patients admitted to department of Otolaryngology and Head-Neck Surgery at Banghabandhu Sheikh Mujib Medical University. Each patient underwent nasal surgery followed by anterior nasal packing for 48 hours. All patients were investigated by tympanometry prior to surgery, 2nd post operative day before pack removal and on 7th post operative day 5 days after pack removal. This study shows that nasal packing result in Eustachian tube dysfunction and negative middle ear pressure which is reversible in nature. Bangladesh J Otorhinolaryngol; April 2017; 23(1): 27-31

The purpose of this study was to examine wideband energy reflectance (ER) at ambient pressure in adults with a variety of middle-ear disorders. The ER results from 9 participants with middle-ear disorders and 1 participant with bilateral sensorineural hearing loss were compared with data provided by a group of 40 young adults with normal hearing sensitivity. Wideband ER results for the participant with sensorineural hearing loss followed the typical pattern of the data for young adults with normal hearing. For the 9 participants with middle-ear disorders (13 ears), the wideband ER responses fell outside the 5th to 95th percentile of the normative data for some portion of the frequency range in patterns that were distinct for otitis media with effusion, otosclerosis, ossicular discontinuity, and perforation of the tympanic membrane. Two ears with hypermobile 226-Hz tympanograms and normal hearing sensitivity had low-frequency ER patterns similar to that of a patient with ossicular discontinuity. One participant with negative middle-ear pressure had high ER in the low frequencies. This distinct ER pattern was similar to the patterns produced by participants with otosclerosis, demonstrating that a correction for middle ear pressure will be important for the clinical application of ER. Overall, the results suggest that wideband ER may be useful as a diagnostic tool in the assessment of middle-ear disorders.

AbstractThe Eustachian tube acts as pressure equalizing tube between the nasopharynx and the middle ear. It also functions as a conduit for removal of secretions from the middle ear and mastoid air cell system into the post nasal space. Eustachian tube function may be assessed objectively using tympanometric measurements. (Brooks, 1968, Lutman, 1987).The post-operative use of nasogastric Ryles tubes is associated with reduced peak middle ear pressure (mmH2O) and reduced peak compliance volumes (ml) as assessed by tympanometry. In addition changes in the appearance of the tympanic membrane may occur with the protracted use of Ryles tubes. This phenomenon is a transient one.Nasogastric tube-induced Eustachian tube dysfunction is a previously unreported entity.

AbstractSixty-three patients undergoing surgery to the nasal septum followed by bilateral packing had pre- and post-operative tympanometry in order to determine the effect on eustachian tube function. Fifty-five of the 126 ears tested (46 per cent) developed a reduction in middle ear pressure of at least 50 daPa; 76 per cent became normal within 24 hours of removing the nasal packs. All ears were asymptomatic and no patient had evidence of middle ear effusion. Nasal packing following septal surgery is a frequent cause of shortlasting eustachian tube dysfunction but rarely severe enough to cause symptoms or middle ear effusion. Tubal dysfunction is most likely due to a combination of surgical oedema and a direct effect of the nasal packing.

Introduction: Eustachian tube dysfunction (ETD) and middle ear barotrauma (MEB) are the most common adverse effects of hyperbaric oxygen (HBO2) treatments. Patients practice equalization maneuvers to prevent ETD and MEB prior to hyperbaric exposure. Some patients are still unable to equalize middle ear pressure. This ETD results in undesirable consequences, including barotrauma, treatment with medications or surgical myringotomy with tube placement and interruption of HBO2. When additional medications and myringotomy are employed, they are associated with additional complications. Methods: A device known as the Ear Popper® has been reported to reduce complications from serous otitis media and reduce the need for surgical interventions (myringotomy). Patients unable to equalize middle ear pressure during initial compression in the hyperbaric chamber were allowed to use the device for rescue. All hyperbaric treatments were compressed using a United States Navy TT9, or a 45-fsw hyperbaric treatment schedule. Patients with persistent ETD and the inability to equalize middle ear pressure were given the Ear Popper upon consideration of terminating their treatment. Results: The Ear Popper allowed all patients to successfully equalize middle ear pressure and complete their treatments. Conclusion: This study substantiates the use of this device to assist in allowing pressurization of the middle ear space in patients otherwise unable to achieve equalization of middle ear pressure during HBO2 treatment in a multiplace chamber.
