Methods: This retrospective cross-sectional study included 751 patients with CRS who underwent bilateral primary functional endoscopic sinus surgery. Before surgery, swab samples were collected from the middle meatus for bacterial cultures using cotton-tipped sticks. Subjects were divided into adult (20 to 64 years, n = 683) and elderly (65 years, n = 68) groups. The results of the bacteria culture were analyzed according to age group and the presence of nasal polyps. Results: The bacterial culture rate was higher in geriatric patients (55.9%) than in adults (44.9%), but the difference was not statistically significant. However, geriatric patients showed a higher bacterial culture rate (57.6%) than adult patients (29.6%) without nasal polyps. This difference was statistically significant. Conclusions: Geriatric patients with CRS exhibited higher bacterial culture rates, particularly on the non-polyp side. These findings suggest a possible age-related susceptibility to microbial colonization, underscoring the need for age-specific infection management strategies.<\/jats:p>","DOI":"10.3390\/diagnostics15233035","type":"journal-article","created":{"date-parts":[[2025,11,28]],"date-time":"2025-11-28T09:56:02Z","timestamp":1764323762000},"page":"3035","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Comparison of Bacteriology Between Geriatric and Adult Rhinosinusitis with and Without NPs"],"prefix":"10.3390","volume":"15","author":[{"given":"Meng-Chun","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Otolaryngology, Tungs\u2019 Taichung Metro Harbor Hospital, Taichung 435403, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-Ching","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Medical Research, Tungs\u2019 Taichung Metro Harbor Hospital, Taichung 435403, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8280-6029","authenticated-orcid":false,"given":"Rong-San","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Tungs\u2019 Taichung Metro Harbor Hospital, Taichung 435403, Taiwan"},{"name":"Department of Otolaryngology, Taichung Veterans General Hospital, Taichung 407219, Taiwan"},{"name":"Department of Medical Research, Taichung Veterans General Hospital, Taichung 407219, Taiwan"},{"name":"School of Medicine, Chung Shan Medical University, Taichung 402306, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"803","DOI":"10.1016\/j.otc.2018.03.008","article-title":"Rhinitis and sinusitis in the geriatric population","volume":"51","author":"Hsu","year":"2018","journal-title":"Otolaryngol.
