    Neurogenic tumors in the post-styloid parapharyngeal space are rare and primarily of vagal or sympathetic origin.

  • 2

    Imaging techniques like CT and MRI can predict the nerve of origin based on vessel displacement patterns.

  • 3

    In a study of 15 patients, imaging accurately predicted the nerve of origin in 88.9% of surgical cases.

  • 4

    Postoperative complications included vocal fold paralysis and Horner's syndrome, with no recorded recurrences.

  • 5

    Further multicenter studies are needed to validate the findings regarding imaging techniques and surgical outcomes.
