Extremely rare bilateral variation of the posterior superior alveolar artery on the maxillary sinus floor observed using CBCT: A case report.

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
The posterior maxilla is particularly susceptible to bone resorption and poses significant anatomical challenges for surgical interventions, including sinus augmentation and dental implant placement. The Posterior Superior Alveolar Artery (PSAA), which usually courses along the lateral wall of the maxillary sinus, is essential for supplying blood to this area. Nonetheless, variations in the PSAA's position and diameter can increase the risk of complications during and after surgery. We here report the case of a 36-year-old male patient presented for implant treatment in the posterior maxilla. A Cone Beam Computed Tomography (CBCT) scan revealed a rare anatomical variation of the large PSAA, observed bilaterally on the floor of the maxillary sinus instead of its typical lateral wall position. This unusual finding was considered in preoperative planning to prevent potential complications during implant placement. Preoperative CBCT imaging is essential in identifying uncommon anatomical variations of the PSAA to ensure safe and effective surgical outcomes in the posterior maxilla. Early identification of such variations can guide surgical planning, prevent complications, and enhance patient safety.
