Ossification of Pterygospinous Ligament: An Incidental Finding in 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
BACKGROUND Ossification of the pterygospinous ligament (PSL) is an osseous variation occasionally observed in the extracranial region of the foramen ovale. It occurs in 1% to 31.2% of the population. The etiology of this condition remains unclear. However, its presence in the skulls of children suggests a hereditary nature. PSL ossification has not been reported in studies on incidental findings in cone beam computed tomography of the maxillofacial region, probably owing to the unfamiliarity with this rare finding. The correct radiographic identification of PSL ossification is crucial as it may produce various neurological disturbances or interfere with surgical procedures involving the infratemporal fossa. CASE REPORT Herein, we present a case of PSL ossification in an asymptomatic 35-year-old woman that was detected as an incidental finding in a cone beam computed tomography for implant treatment planning and discuss the clinical significance of this condition. CONCLUSIONS Although this osseous variant is well known in the anatomical literature, we believe it is rarely discussed among dentists. Healthcare providers, especially dentists, should rule out PSL ossification when a patient presents with a neurological disturbance of unknown causes.
