Sinonasal Polyposis

ABSTRACT Objective/hypothesis Nasal and paranasal sinus disease can cause Eustachian tube (ET) dysfunction leading to middle ear (ME) hypoventilation. Persistent ME hypoventilation can result in ME conditions like retraction of tympanic membrane, otitis media with effusion, and chronic ME disease. Aim Aim of this study was to evaluate the ET function in cases of sinonasal polyposis. Evaluation was done by doing tympanometry. Materials and methods This was a hospital-based prospective study consisting of 42 patients (84 ears) of nasal polyposis, of which 27 patients had antrochoanal (AC) polyp and 15 patients had ethmoidal polypi. After thorough history and detail clinical examination, tympanometry was done in all patients 1 day prior to surgery and 4 to 6 weeks after surgery. Results Preoperatively in 30 ears (15 patients) of ethmoidal polypi had normal tympanogram (A type) in 40% ears and abnormal tympanogram (B and C) in 60% ears. Postoperatively 80% had A tympanograms and 20% had abnormal tympanogram. There was significant improvement on removal of polypi (p = 0.004). Preoperatively 54 ears (27 patients) of AC polyp had normal tympanogram (type A) in 55.56% ears and abnormal tympanogram (B and C) in 44.44% ears. Postoperatively normal tympanogram was seen in 81.48% and abnormal tympanogram in 18.52% ears, so there was significant improvement after functional endoscopic sinus surgery (p = 0.007). Conclusion Eustachian tube dysfunction was present preoperatively in 60 and 44.44% in ethmoidal and AC polypi respectively, while in postoperative period dysfunction was 20 and 18.52%. So function improves on removal of polyp. How to cite this article Mane SB, Dasgupta KS. Sinonasal Polyposis and Its Effect on Eustachian Tube Function. Clin Rhinol An Int J 2016;9(2):77-80.

Background: Patients with chronic rhinosinusitis (CRS) often have Eustachian tube dysfunction (ETD) symptoms. This study aimed to prospectively investigate the effect of endoscopic sinus surgery (ESS) on improvement of Eustachian tube function in CRS patients with ETD from a Chinese population and determine factors associated with improvement. Methods: A prospective study was performed in CRS patients with ETD who underwent ESS from 3 tertiary medical centers in south China. The Eustachian tube Dysfunction Questionnaire 7 (ETDQ-7), Sinonasal Outcome Test 22 (SNOT-22), tympanograms, endoscopic findings and Valsalva maneuver were recorded and analyzed preoperatively and postoperatively at 8-12 weeks. Results: A total of 70 CRS patients with ETD were included in this study. The ETDQ-7 score and the ability of positive Valsalva maneuver in CRS patients were significantly improved postoperatively at 8-12 weeks. The number of patients with type A tympanogram was increased postoperatively. Reduced Eustachian tube mucosal inflammation was also observed postoperatively. In addition, ESS appeared to reverse slight tympanic membrane atelectasis after 8-12 weeks. Moreover, improvement in tympanogram was presented in more than half of CRS patients with concomitant otitis media with effusion postoperatively at 8-12 weeks. Univariate and multivariate analysis revealed failure of normalization of ETDQ-7 postoperatively was associated with concomitant allergic rhinitis and higher preoperative SNOT-22 score. Conclusions: This study confirms Eustachian tube function is often improved after ESS in CRS patients with ETD. Concomitant allergic rhinitis and higher preoperative SNOT-22 score are associated with failure of normalization of ETD symptoms.

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 studies in humans have indicated that functional obstruction of the eustachian tube (ET) is an important factor in the pathogenesis of otitis media with effusion (OME). This type of obstruction appears to be related to the structural properties of the tube, or to an inefficient active tubal opening mechanism, or both. In this study, functional ET obstruction was created in 22 rhesus monkeys ( Macaca mulatta) by surgically altering the tensor veli palatini (TVP) muscle using three different procedures: 1) complete excision of the muscle; 2) transection of the superficial muscle bundle; or 3) transposition of the muscle tendon medial to the hamular process. Prior to surgery, weekly tympanometry, pneumatic otoscopy, and otomicroscopic examinations were performed for a period of at least six months to document middle ear (ME) status. A minimum of four ET function tests were performed on each animal using the inflation-deflation and forced-response tests. Following surgery, these tests and examinations were continued for periods of up to one year. Postoperatively, the animals in which the TVP had been excised developed a sterile ME effusion which proved to be a chronic condition which persisted throughout the follow-up period. Eustachian tube function tests showed a complete absence of any active tubal dilation by swallowing. Animals that had the muscle transected developed abnormal ME pressures, or effusions, or both, which returned to normal in some ears, but which were recurrent or chronic in others. Eustachian tube function tests in these animals showed an initial loss of active tubal function which gradually improved, but not to normal levels, presumably as a result of healing of the muscle. In cases in which the muscle was transposed the ME pathology and ET dysfunction were similar after the surgery, but improved within a short period of time. These data suggest that alteration of the TVP muscle can create functional obstruction of the ET. The severity of ET obstruction depends upon the surgical procedure undertaken. The results of postoperative ET function tests were similar to those recorded from children with recurrent and chronic OME.

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.

Induced Changes

Many studies have shown that antihistamines and decongestants are of little use in the treatment of acute otitis media and otitis media with effusion, or in the prophylaxis of these disorders.1 However, because some drugs can improve otitis media with effusion (glycocorticosteroids)2–4 and some can impair the opening function of the eustachian tube (atropine),5 it seems justified to continue studies of eustachian tube function and medication.
