Introduction Eustachian tube (ET) dysfunction plays an important role not only in the pathophysiology of various middle ear disorders, but also in predicting the outcome of the treatment. As there is no single test that assesses both the anatomic and physiological functions of the ET, a combination of tympanometry and dynamic slow motion video endoscopy may improve the sensitivity of ET function assessment. Objective To find out if there is any correlation between dynamic slow motion nasal video endoscopy and impedance audiometry in assessing ET function in patients with middle ear diseases. Methods Ours was a descriptive study performed with 106 patients attending the Ear, Nose and Throat (ENT) Outpatient Department of a tertiary care center in South India with features suggestive of middle ear disease. All patients underwent impedance audiometry and dynamic slow motion nasal video endoscopy, and were graded based on the severity of the ET pathology. Results A total of 47 out of 97 patients with abnormal endoscopy findings also had abnormal impedance audiometry. The correlation was greater among the patients with higher grades of ET dysfunction. The endoscopy findings of 106 cases, when correlated with middle ear manometry, revealed that 56 cases showed complete agreement, and 50 cases showed disagreement. The nasal endoscopy results, when correlated with middle ear manometry studies by using McNemar's chi-squared (χ2) test, showed a significant association between the 2 tests (p = 0.017). Conclusion There is a significant alteration in middle ear pressure as the severity of the ET tube dysfunction increases. Impedance audiometry and nasal endoscopy provide a better measure of ET function.

AbstractObjective:To assess the efficacy of dynamic slow motion video endoscopy as a test of eustachian tube function based on its correlation with the eustachian tube swallow test.Method:The eustachian tube swallow test and dynamic slow motion video endoscopy were performed on 100 clinically normal middle ears of adults undergoing rigid nasal endoscopy for various indications. The dynamic slow motion video endoscopy findings were interpreted by three observers who were blind to the results of the eustachian tube swallow test, and the findings of both techniques were compared.Results:There was a statistically significant correlation between the dynamic slow motion video endoscopy and eustachian tube swallow test results for some of the more lenient criteria. Five of the 100 eustachian tubes had a floppy medial cartilaginous lamina which appeared to contribute to the eustachian tube dysfunction.Conclusion:Dynamic slow motion video endoscopy appeared to over-diagnose eustachian tube dysfunction when used as a standalone test of eustachian tube function. However, when used in combination with other tests of eustachian tube function, it can provide valuable information regarding the structural and functional status of the pharyngeal end of the eustachian tube.

A Prospective Study

An aberrant right subclavian artery (ARSA) can be overlooked by the conventional method as described by Chaoui et al., due to acoustic shadowing. The aim of this study was to evaluate the feasibility and accuracy of a novel screening method for ARSA by demonstrating the brachiocephalic artery bifurcation, referred to as the “No ARSA” sign. A prospective study conducted at a tertiary care center between 2018 and 2019 included unselected pregnant patients at a median gestational age of 15.1 (14.2–22.1; IQR (inter-quartile range)) weeks, who had been referred for a routine or targeted anomaly scan. All participants were scanned for the presence or absence of ARSA using both the conventional and the novel “No ARSA” methods for validation purposes. A total of 226 unselected patients were enrolled in the study. The “No ARSA” sign was visualized in 218 fetuses (96.5%). In the remaining 8 cases (3.5%), the “No ARSA” sign was not demonstrated. In these fetuses, an ARSA was visualized by the conventional method. The new method exhibited 100% feasibility and was in complete agreement with the conventional method. Intra- and inter-observer agreement was excellent (κ = 1). The results of the study suggest that the “No ARSA” sign is an efficient and reliable screening tool for ARSA.

<p class="abstract"><strong>Background:</strong> Diagnostic nasal endoscopy (DNE) and computed tomography (CT) of para nasal sinuses play an important role in the diagnosis and treatment of chronic rhinosinusitis (CRS). The aim and objective of the study is to see the anatomical variations of the sinonasal region in CRS on DNE and CT paranasal sinuses (PNS).</p><p class="abstract"><strong>Methods:</strong> A descriptive type retrospective study of 30 patients attending the ENT outpatient department of our tertiary care center clinically diagnosed as CRS with symptoms persisting for 12 weeks or more, along with previously failed medical management, including topical nasal steroids, systemic decongestant and extended courses of antibiotics and who were willing to undergo endoscopic sinus surgery are included.  </p><p class="abstract"><strong>Results:</strong> Majority of the patients had septal deviation either an anterior or posterior deviation but majority of the cases are asymptomatic for the deviation. Anatomical variations of uncinate process, middle turbinate, inferior turbinate, frontal recess, agger nasi cells, haller cells were studied as well.</p><p class="abstract"><strong>Conclusions:</strong> Prolonged duration of  rhinosinusitis symptoms (more than 8-12 weeks) is the primary reason to evaluate a patient for CRS and making the choice between CT PNS or DNE is patient and disease dependent. Understanding the advantages and disadvantages of each helps us realize that they are of synergistic in nature and not competitive.</p>

<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>
