Abstract

MEDICAL THERAPY Target Population Adults with histologically proven or suspected vestibular schwannomas with neurofibromatosis type 2 (NF2). Question What is the role of bevacizumab in the treatment of patients with vestibular schwannomas? Recommendations Level 3: It is recommended that bevacizumab be administered in order to radiographically reduce the size or prolong tumor stability in patients with NF2 without surgical options. Level 3: It is recommended that bevacizumab be administered to improve hearing or prolong time to hearing loss in patients with NF2 without surgical options. Question Is there a role for lapatinib, erlotinib, or everolimus in the treatment of patients with vestibular schwannomas? Recommendations Level 3: Lapatinib may be considered for use in reducing vestibular schwannoma size and improvement in hearing in NF2. Level 3: Erlotinib is not recommended for use in reducing vestibular schwannoma size or improvement in hearing in patients with NF2. Level 3: Everolimus is not recommended for use in reducing vestibular schwannoma size or improvement in hearing in NF2. Question What is the role of aspirin, to augment inflammatory response, in the treatment of patients with vestibular schwannomas? Target Population Any patient with a vestibular schwannoma undergoing observation. Recommendation Level 3: It is recommended that aspirin administration may be considered for use in patients undergoing observation of their vestibular schwannomas. Question Is there a role for treatment of vasospasm, ie, nimodipine or hydroxyethyl starch, perioperatively to improve facial nerve outcomes in patients with vestibular schwannomas? Target Population Adults with histologically proven or suspected vestibular schwannomas. Recommendation Level 3: Perioperative treatment with nimodipine (or with the addition of hydroxyethyl starch) should be considered to improve postoperative facial nerve outcomes and may improve hearing outcomes. PREHABILITATION Question Is there a role for preoperative vestibular rehab or vestibular ablation with gentamicin for patients surgically treated for vestibular schwannomas? Target Population Adults with histologically proven or suspected vestibular schwannomas. Recommendations Level 3: Preoperative vestibular rehabilitation is recommended to aid in postoperative mobility after vestibular schwannoma surgery. Level 3: Preoperative gentamicin ablation of the vestibular apparatus should be considered to improve postoperative mobility after vestibular schwannoma surgery. SURGICAL THERAPY Question Does endoscopic assistance make a difference in resection or outcomes in patients with vestibular schwannomas? Target Population Vestibular schwannoma patients, who are surgical candidates. Inclusion in this analysis required resection utilizing the endoscope, either as the primary operative visualization or microscopic assistance with more than 20 patients treated. Recommendation Level 3: Endoscopic assistance is a surgical technique that the surgeon may choose to use in order to aid in visualization.
