Introduction: The AMSA® manosonic nebulizer uses acoustic vibration and a flow of air to create an aerosol from a solution or suspension of a drug. The aerosol created this way is claimed to have enhanced penetration and drug delivery. It is administered under short-term overpressure, meaning that the aerosol is able to penetrate into the middle ear through the Eustachian tube (ET)., Purpose: of the study: The aim of this study is to identify the active substances used in AMSA® manosonic nebulization for treating common ENT diseases in children aged 2-17 years and to evaluate the overall effectiveness of AMSA® manosonic nebulization in this context. Assessments were done by comparing conditions before and after nebulization using the following tests: (1) Eustachian tube function test, (2) tympanometry, and (3) otoscopy., Material and Methods: This study was a retrospective study with ethics committee consent. 129 children, comprising 56 girls and 73 boys. They were aged between 2 and 17 years, with a mean age of 6.9 years (SD = 3.0). There were 74 children up to 6 years and 55 children over 6 years of age. Children had the following conditions: (1) chronic otitis media with effusion, OME (n = 86), (2) Eustachian tube dysfunction, ETD (n = 34) (3) Other conditions (e.g. cholesteatoma, retraction pocket), (n = 9). Combination of medicines administered in this study was: Budesonide + ambroxol (with or without NaCl), Budesonide (with or without NaCl), Budesonide + N-acetylcysteine (with or without NaCl), Budesonide + hyaluronic acid, Budesonide + ambroxol (with hyaluronic acid), Ambroxol (with or without NaCl)., Results: The number of nebulizations ordered was between 1 and 20 treatments, but most commonly, pa-tients were given a nebulization series of 10 treatments. This was the case for 80.6 % of the patients. Most patients with OME and ETD had 10 treatments ordered (79 % and 79.5 %, respectively), while all patients with other conditions had 10 treatments. Analysis of the tympanometry results was done in terms of the number of affected ears (not by individual). There were 210 ears with complete tympanometry (both pre and post), including 142 ears with OME, 54 with ETD, and 14 others. Statistically significant changes (improvements) after AMSA nebulizations were found for statistic compliance and middle ear pressure. Otoscopy assessments were done in all ears. The results were abnormal in 155 ears (73.8 %) and normal in 55 ears (26.2 %). After AMSA nebulizations, the number of abnormal results decreased to 117 ears (55.7 %) and normal results were found in 93 ears (44.7 %)., Conclusion: Use of the AMSA manosonic nebulizer appears to be an effective way of improving chronic medical conditions in children - such as chronic otitis media with effusion and Eustachian tube defect - but only if patient compliance can be achieved. The most frequently used active substance was budesonide, irrespective of whether additional secretolic/mucolytic agent was administered., Competing Interests: Declaration of competing interest We confirm that this work is original manuscript (The AMSA® manosonic nebulizer for ENT disease among children in Poland) and has not been published elsewhere, nor is it currently under consideration for publication elsewhere.

Background: Topical nasal decongestants are frequently used as part of the medical management of symptoms related to Eustachian tube dysfunction. Objective: This study aimed to assess the effect of topical xylometazoline hydrochloride sprayed in the anterior part of the nose on Eustachian tube active and passive opening in healthy ears. Methods: Active and passive Eustachian tube function was assessed in healthy subjects before and after intranasal administration of xylometazoline spray, using tympanometry, video otoscopy, sonotubometry, tubo-tympano-aerodynamic-graphy and tubomanometry. Results: Resting middle-ear pressures were not significantly different following decongestant application. Eustachian tube opening rate was not significantly different following the intervention, as measured by all function tests used. Sonotubometry data showed a significant increase in the duration of Eustachian tube opening following decongestant application. Conclusion: There remains little or no evidence that topical nasal decongestants improve Eustachian tube function. Sonotubometry findings do suggest that further investigation with an obstructive Eustachian tube dysfunction patient cohort is warranted. [ABSTRACT FROM AUTHOR]

Objectives: Pre-operative eustachian tube function (ETF) is an important,,factor for the postoperative success after tympanoplasty, though much debates have been reported. In this study, we investigated the tympanogram changes after tympanoplasty, indirectly checking up ETF, to find out the relationship between tympanogram changes and associated factors after tympanoplasty. Material: Included in this study were 238 cases of tympanoplasty (canal wall up mastoidectomy with tympanoplasty type I or tympanoplasty type I only) performed by one surgeon for chronic otitis media from January, 2012 to June, 2017. In all cases, tympanometric tests were undertaken at one month, three month, six month, and one year post-operatively, and pure tone audiometry tests were taken at 1 year, post operatively. Results: The average hearing level and air-bone gap were 41.8±19.7 dB, and 17.1±9.3 dB, pre-operatively, and 29.9±21.1 dB, and 6.9±8.5 dB, 1 year post-operatively, respectively. Most of the cases showed improvement in hearing. The results of tympanometry showed that hearing improvement was greater for the A type than for the B or C type (p<0.001). The smaller the size of the tympanic membrane was, the higher the type A tympanogram appeared (p=0.008). Conclusions: The estimation of pre-operative ETF using post-operative tympanogram changes can give insight to the degree and process of recovery of the normal middle ear after tympanoplasty.
