Do Anatomical Variations Affect the Location of Solitary Sphenoid Sinus Fungal Balls? A 10-Year Retrospective 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 Objectives: Sinonasal fungal balls (FBs) most commonly occur in the maxillary sinus, followed by the sphenoid sinus (SS). Relatively little is known about the predisposing factors and pathogenesis of unilateral sphenoid sinus fungal balls (SSFBs) compared to maxillary sinus FBs. We investigated whether anatomical variations have clinical implications for the location of unilateral SSFBs. Methods: This study included 33 patients who underwent endoscopic sinus surgery for unilateral SSFBs between 2010 and 2021. Preoperative computed tomography scans were used to analyze the presence of anatomical variations, including sphenoid lateral recess, complete accessory septum of the SS, types of SS pneumatization, anterior and posterior nasal septal deviation (NSD), cephalocaudal NSD, concha bullosa (CB), Haller cell (HC), paradoxical middle turbinate (MT), everted uncinated process (UP), and Onodi cell. Results: The presence of HC (33.3% vs. 12.1%, p=0.04), complete accessory septum of the SS (51.6% vs. 25.8%, p=0.04), and the sellar type of the SS (90.9% vs. 50%, p=0.003) differed significantly according to the presence or absence of FBs in the SS. However, other anatomical variations, including NSD, CB, paradoxical MT, everted UP, Onodi cell, and sphenoid lateral recess, were not significantly associated with the presence of unilateral SSFBs (all p>0.05). In the multivariable analysis, only sellar-type pneumatization of the SS showed a statistically significant relationship with SSFB, not the combined conchal and presellar type (adjusted odds ratio, 8.96; 95% confidence interval, 1.27-63.19; p=0.03). Conclusion: We demonstrated that unilateral SSFBs were most strongly associated with the ipsilateral type of SS pneumatization, followed by the presence of HC and a complete accessory septum of the SS. Intranasal anatomical variations may play a significant role in the location of unilateral SSFBs.
