Clinical and Radiological Significance of Anatomical Variations in Paranasal Sinuses: A Retrospective CT-Based Study.

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
Background and objective Anatomical variations of the paranasal sinuses influence sinus drainage and airflow, contributing to chronic rhinosinusitis. This study aimed to assess the prevalence of these variations and their association with sinus infections by using CT findings. Methods A retrospective CT-based analysis of 75 patients (aged 25-70 years) was conducted. Anatomical variations, including nasal septal deviation (NSD), concha bullosa, agger nasi cells, Haller cells, and Onodi cells, were recorded. The association between these variations and affected sinuses was analyzed using the chi-squared test and Fisher's exact test; a p-value <0.05 was considered statistically significant. Results NSD was the most common anatomical variation, observed in 50 patients (66.6%), followed by hypertrophic ethmoidal bulla in 35 (46.6%), and concha bullosa in 30 (40%). Among the affected sinuses, maxillary sinusitis was the most frequently observed, affecting 60 patients (80%), followed by frontal in 45 (60%), ethmoidal in 30 (40%), and sphenoid sinusitis in eight (10.6%). Significant associations were found between NSD, concha bullosa, and maxillary sinusitis; agger nasi cells with frontal/ethmoid sinusitis; Haller cells with maxillary sinusitis; and Onodi cells with sphenoid sinusitis (p<0.05). Conclusions Paranasal anatomical variations significantly correlate with sinusitis, emphasizing the importance of preoperative CT evaluation in guiding medical and surgical management. Recognizing these variations enhances diagnostic accuracy and improves surgical outcomes in functional endoscopic sinus surgery (FESS).
