This study is based on preoperative results of impedance audiometry in correlation with the data from the medical history of chronic sinusitis, symptoms reported by the patients, results of Computed Tomography (CT), and the stage of inflammatory changes according to Lund and Mackay score.<\/br><\/br> <b>Results:<\/b> The significant majority of patients in our study (65) had advanced auditory tube symptoms, while 4 patients suffered from symptoms significantly impacting daily functioning. In patients with chronic sinusitis the analysis demonstrated that tympanometry type B (12.67) and C (12.4) occured with significantly higher Lund-Mackay score than type A (9.2). In allergy sufferers type B of tympanometry was more often observed with characteristically bilaterally located inflammatory changes in maxillary and anterior ethmoid sinuses.<\/br><\/br> <b>Conclusions:<\/b> The profile of chronic sinusitis patient in whom Eustachian tube dysfunction is more often observed, is as follows:<\/br><\/br> \u2022 Lund and Mackay score above 12;<\/br><\/br> \u2022 pathological changes are bilaterally observed in maxillary and anterior ethmoid sinuses;<\/br><\/br> \u2022 decrease of nasal patency and postnasal drip;<\/br><\/br> \u2022allergy;<\/br><\/br> \u2022overusing alcohol and cigarettes, at least alcohol;<\/br><\/br> \u2022 worse result of Lund and Mackay score and the age of patients \u2013 2 factors favoring the dysfunction of the Eustachian tube.<\/jats:p>","DOI":"10.5604\/01.3001.0016.2702","type":"journal-article","created":{"date-parts":[[2023,2,17]],"date-time":"2023-02-17T11:01:11Z","timestamp":1676631671000},"page":"32-38","source":"Crossref","is-referenced-by-count":1,"title":["The Variability of function of the Eustachian tube in patients with chronic paranasal sinusitis"],"prefix":"10.5604","volume":"77","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0489-5230","authenticated-orcid":false,"given":"Sebastian","family":"Koco\u0144","sequence":"first","affiliation":[{"name":"Audiology Laboratory, Department of Otolaryngology, Jagiellonian University Medical College in Cracow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0765-9700","authenticated-orcid":false,"given":"Remigiusz","family":"Ziarno","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Jagiellonian University Medical College in Cracow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0362-4500","authenticated-orcid":false,"given":"Konrad","family":"Sk\u00f3rkiewicz","sequence":"additional","affiliation":[{"name":"Department of Medical Physics, Faculty of Physics, Astronomy and Applied Computer Science of the Jagiellonian University, Cracow, Poland; Department of Biophysics, Faculty of Medicine, Jagiellonian University Medical College, Cracow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0840-9268","authenticated-orcid":false,"given":"Maciej","family":"Wiatr","sequence":"additional","affiliation":[{"name":"Audiology Laboratory, Department of Otolaryngology, Jagiellonian University Medical College in Cracow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1793-0744","authenticated-orcid":false,"given":"Agnieszka","family":"Wiatr","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Jagiellonian University Medical College in Cracow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3689","reference":[{"key":"235016r1","doi-asserted-by":"crossref","unstructured":"Schuon R., Schwarzensteiner J., Paasche G., Lenarz T., John S.: Functionalaspects of the Eustachian tube by means of 3D-modeling.
