Evaluation of maxillary sinus pathologies and the posterior superior alveolar artery canal using cone-beam computed tomography.

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
objectiveThis study aims to determine the anatomical relationship between the posterior superior alveolar artery (PSAA) and the lateral wall of the maxillary sinus during preoperative radiological evaluations in the posterior maxillary dental region, as well as to evaluate the prevalence of PSAA and its potential associations with sinus pathologies. MATERIALS AND
methodsThis retrospective study is based on the analysis of Cone-Beam Computed Tomography (CBCT) data from 510 sinuses of 255 patients. The visibility of the PSAA vascular canal, artery diameters, vertical distance between the alveolar crest and the artery, and the distance to the sinus floor were measured in coronal sections. Additionally, the relationships between sinus pathologies and septa within the sinuses and the PSAA were evaluated.
resultsPSAA was detected bilaterally in the majority of patients (70.2%). Sinus pathologies and the presence of septa were also examined, revealing that 36.9% of the sinus pathologies were bilateral. Chi-square analyses showed no statistically significant relationship between gender and the presence of PSAA. Female patients had a higher incidence of sinus pathologies compared to males (p = 0.002). No significant relationship was found between the presence of PSAA and septa.
conclusionsThis study highlights the importance of considering the anatomical position and prevalence of the PSAA during preoperative radiological evaluations in the posterior maxillary region. This study identified the PSAA as predominantly located in the lateral wall of the maxillary sinus, an anatomical feature of critical importance during preoperative radiological evaluations to minimize vascular complications.
