Influence in infraorbital foramen involvement on the cheek in maxillary fractures: a prospective observational study.
Article in Archives of craniofacial surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundInfraorbital nerve dysfunction frequently occurs after maxillary fractures. This study aimed to determine whether maxillary fractures involving the infraorbital foramen affect the recovery of infraorbital nerve function.
methodsIn this prospective study, 60 patients who received treatment for unilateral maxillary fractures between January 2020 and December 2022 were analyzed, with a follow-up period of over 1 year. Computed tomography scans were employed to categorize the fractures into three types according to the location of the fracture line relative to the infraorbital foramen. Sensory changes in four predetermined areas, supplied by the infraorbital nerve, were evaluated preoperatively and at 1 week, 1 month, 3 months, 6 months and 1 year postoperatively using the two-point discrimination test and the monofilament test.
resultsParesthesia was observed in all patients with maxillary fractures. In the majority of instances, sensory deficits resolved spontaneously within 1 year. However, in patients whose fracture lines encroached upon the infraorbital foramen, the severity of paralysis was greater, and the rates of recovery were slower.
conclusionThe degree of infraorbital nerve function after a maxillary fracture was influenced by the involvement of the infraorbital foramen. Therefore, in the management of patients with maxillary fractures, computed tomography scans can serve as a predictive tool for the potential severity of paresthesia and the anticipated recovery rate.
