Although microsurgical techniques have greatly improved the surgical outcome of auditory neuromas, they can still cause facial paralysis, hearing loss, and even life-threatening conditions for patients. Gamma Knife, on the other hand, can achieve the goal of treating auditory neuroma without life-threatening conditions. The treatment of auditory neuroma with Gamma Knife, although not completely resected, has a local control rate of tumor similar to microsurgery, but the damage to the face and auditory nerve is less than microsurgery, and there is no mortality. Gamma knife is suitable for treating small (less than 3 cm in diameter) tumors, especially those less than 1 cm located near the auditory nerve foramen, with good therapeutic results and few postoperative complications. For postoperative residual tumors that are partially or subtotally resected, gamma knife treatment can also be used to prevent their continued growth or recurrence. For tumors larger than 3 cm in diameter or those with obvious symptoms of occupancy and intracranial hypertension, microsurgical resection is still appropriate.
