Postoperative rhinosinusitis and microbiological outcomes following endoscopic endonasal approaches: A retrospective analysis of 300 patients.
Article in Journal of the Chinese Medical Association : JCMA, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEndoscopic endonasal approaches (EEAs) are an efficient way to manage skull base lesions; however, studies regarding postoperative rhinosinusitis are limited. This study analyzed the incidence of postoperative rhinosinusitis, the associated risk factors, microbial species, and antibiotic usage in patients who underwent EEA.
methodsPatients who underwent EEAs at a tertiary referral hospital between July 2015 and May 2019 were retrospectively evaluated. Postoperative rhinosinusitis was defined as the presence of a purulent nasal discharge on postoperative endoscopic examination. The mucopus was aspirated and subjected to bacterial culture analysis. The culture results of various groups were analyzed.
resultsThis study included 300 patients, and the incidence of post-EEA rhinosinusitis was 59.7%. History of endonasal surgery was an independent predictive factor for post-EEA rhinosinusitis (odds ratio [OR]: 2.54 [1.28-5.05], p = 0.007). Lesions in the anterior skull base were associated with prolonged use of antibiotics for rhinosinusitis during postoperative care (OR: 3.91 [1.32-11.52], p = 0.013). Staphylococcus aureus was the most common causative pathogen (52.3%), followed by methicillin-resistant S. aureus (MRSA) (20.7%), Pantoea dispersa (14.4%), and Pseudomonas aeruginosa (52.3%). P. aeruginosa was more significant in the complex reconstruction group than in the control group. While most patients with post-EEA rhinosinusitis experienced a transient clinical course, one female patient underwent endoscopic sinus surgery (ESS) for prolonged rhinosinusitis.
conclusionRhinosinusitis is common in the postoperative stage of the EEA. As it usually lasts for a short duration and is treatable with proper medication, aggressive nasal care during the postoperative period is required to prevent related nasal morbidities.
