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.

<p class="abstract"><strong>Background:</strong> Eustachian tube maintains middle ear pressure equal to that of atmosphere. Its function may be deranged due to variety of factors like adenoids, cleft palate, nasogastric tubes, allergy, nasopharyngeal intubations and also by nasal packing following septal surgery. Our aim was to evaluate the effect of anterior nasal packing protocol, on eustachian tube function, followed in our ENT Department for nasal surgeries.</p><p class="abstract"><strong>Methods:</strong> A descriptive study was done on 60 patients undergoing nasal surgery from March to November 2018 was done in the ENT Department of a tertiary care hospital.<strong> </strong>All patients underwent pre-operative otoscopic examination followed by tympanometry. Tympanometry was repeated following nasal surgery with nasal pack in situ and again 24 hours after removal of pack. The results of all these 3 impedance audiometries were tabulated and analysed.  </p><p class="abstract"><strong>Results:</strong> Pre-operatively both ears in all the patients showed type a tympanometry, which implied normal eustachian tube function. Out of 60 patients who underwent nasal surgeries, 40 had abnormal impedance tympanograms immediately after surgery. 26 patients had abnormal impedance tympanogram after pack removal. These patients were treated with nasal decongestants and antibiotics which were routinely prescribed as a post-operative prophylaxis. These patients 1 week after pack removal recorded a normal tympanogram.</p><p class="abstract"><strong>Conclusions:</strong> Changes in middle ear pressure following nasal packing associated with most nasal surgeries were transient but not severe. Hence, we conclude that anterior nasal packing for 24 hours is considered safe, if no other co-morbid factors for altering middle ear pressures are present.</p>

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.

Previous research on eustachian tube function has been devoted mainly to the study of the tubal opening ability and pressure equalization. This article summarizes a series of experimental studies focusing on the closing ability of the tube. Results support the belief that the purpose of the tube should be seen primarily as protecting the middle ear from the extensive pressure variations that physiologically take place in the nasopharynx. A number of studies of diseased ears have shown that tubal malfunction was characterized mainly by a reduced ability to withstand negative pressure in the nasopharynx. Sniffing can evacuate the middle ear, causing high negative intratympanic pressure. It seems likely that this mechanism is involved in the development of middle ear effusion and manifest retraction-type middle ear disease.

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

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.
