Task: Question Generation
Input (English): Trigeminal neuralgia is the most common neurological cause for facial pain. Contemporary interventional treatment relies on surgical microvascular decompression or, alternatively, percutaneous interventions targeting the semilunar ganglion via the foramen ovale. For the latter approach, only free-hand punctures using fluoroscopy devices have been reported. Therefore, the present study aimed to evaluate a new fluoroscopy-based guidance device for transforaminal puncture.', 'Two experienced examiners punctured the foramen ovale bilaterally free-hand, and using a guidance device in human cadavers (n = 9). The number of attempts for puncture was recorded. A new attempt was counted each time the needle had to be retracted for redirection.', 'As compared to the free-hand puncture of the foramen ovale (4.44 +/- 2.79), the new guidance device significantly reduced the number of trials needed (1.37 +/- 0.69).
Output (English): Does a new guidance device facilitate percutaneous puncture of the foramen ovale in human cadavers?
