The relationship between structures affecting maxillary sinus ventilation and maxillary sinus volume: a CT 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
purposeThis study aims to identify anatomical variations inside and outside the maxillary sinus (MS), determine their prevalence and coexistence, and investigate their relationship with MS volume in individuals without MS pathology, using ImFusion Suite software.
methodsAnalysis of 330 paranasal CT scans obtained from the radiology archive (2018-2021) was performed using the ImFusion Suite program. Anatomical variations, including accessory ostium, Haller cells, ethmomaxillary sinus, concha anomalies, septa, and impacted teeth, were identified and their frequency of coexistence was determined. MS volume and nasal septum deviation (NSD) angle were measured. The relationship between MS volume and gender, as well as the impact of anatomical variations on MS volume, was analyzed. Statistical analyses were conducted using SPSS software.
resultsThe most common anatomical variation was NSD (98%), while the least common was ethmomaxillary sinus (9.4%). Middle and inferior concha hypertrophy were more frequent in males, whereas concha bullosa and impacted teeth were more prevalent in females (p < 0.05). A normal anatomical appearance on CT scans was observed in only 2.1% of cases (3.5% in males; 1.1% in females), with a notable coexistence of multiple variations. MS volume was significantly higher in males (right: 16.79 ± 5.23 cm
conclusionThis study provides a comprehensive analysis of anatomical variations in the MS and their relationship with MS volume. The findings indicate that septa increase MS volume, while a higher NSD angle (≥9°) is associated with reduced MS volume. Other variations, including accessory ostium, Haller cells, and concha anomalies, showed no significant impact on MS volume. These results highlight the importance of detailed radiological evaluation in clinical and surgical planning.
