Trigeminal schwannomas (TS) are rare entities occurring in various trigeminal nerve locations and present a peak incidence between the fourth and fifth decades of life, being more common in women. Patients usually present with symptoms of trigeminal nerve dysfunction. Depending on the tumor’s topography, various approaches might be used to obtain its gross total resection. Trigeminal schwannoma’s classification, nuances of the approaches, pathology, postoperative care, and outcomes are revised as follows. In conclusion, anatomical knowledge and the disease’s comprehension are essential when dealing with such lesions, and despite their rarity, we must be obstinately committed to the surgical technique and devoted to the patient’s functional postoperative outcome.

Jugular foramen paragangliomas are rare neoplasms occurring with a myriad of symptoms originating from paraganglionic tissue derived from the neural crest, comprising about 0.03% of all human tumors. Patients usually present with symptoms of dysfunction of VI, VII, VIII, IX, X, XI, XII nerves and sympathetic trunk. Depending on the tumor’s topography, various approaches might be used to obtain its gross total resection. Jugular Foramen’s paraganglioma classification, nuances of the approaches, pathology, postoperative complications, and outcomes are revised as follows. In conclusion, anatomical knowledge and the disease’s comprehension are essential when dealing with such tumors, and despite their rarity, we must be obstinately committed to the surgical technique and devoted to the patient’s functional postoperative outcome.
