Careful preoperative assessment and control of comorbid conditions can further diminish the risks of complication. The outcome and prognosis for cure from surgical resection depends on the histology, size, and location of the tumor and the approach chosen. Cessation of tumor growth from primary radiation also depends on the specific factors listed above. Expected facial palsy rates are high for primary facial schwannomas. The effect on quality of life from a facial nerve palsy is quite significant.
Results are also very dependent on the experience and skills of the surgeon.
Endoscopic surgical techniques in the CPA have improved visualization of the tumor and adjacent structures. Stereotactic methods have improved accuracy of the delivery of microsurgical dissection and radiation therapy, thus minimizing damage to adjacent tissue. New radiation delivery protocols, though incompletely followed up, show some promise as primary or adjuvant therapy of some of these lesions. Head and Neck Imaging.
