Vestibular Schwannoma: Comprehensive Evaluation, Management, and Intraoperative Monitoring

Please note: exam questions are subject to change.

1. Which of the following may indicate a poorer prognosis for hearing preservation outcomes? Pre-operative hearing loss Caloric weakness greater than 50% Present otoacoustic emissions Absent Auditory Brainstem Response (ABR)
2. If a patient has a vestibular schwannoma in the right ear, what pattern might you expect for acoustic reflex testing? Present in all conditions Absent in all conditions Absent for conditions when the probe is in the right ear Absent for conditions when the stimulus is in the right ear
3. The most common presenting feature of vestibular schwannoma is: Dizziness Facial paralysis Facial numbness Asymmetric hearing loss
4. In larger tumors, the most common cranial neuropathy is: Tongue weakness (CN XII) Facial paralysis (CN VII) Facial numbness (CN V) Swallowing dysfunction (CN X)
5. What is the second most common lesion of the cerebellopontine angle after vestibular schwannoma? Lipoma Epidermoid Meningioma Hemangioma
6. What is the most common determinant of treatment strategy for vestibular schwannoma? Size Growth Hearing status Age
7. Which microsurgical treatment approach definitively results in post-operative deafness? Retrosigmoid Suboccipital Middle cranial fossa Translabyrinthine
8. Which artery is part of the critical blood supply to the Cochlea? MCA (Middle cerebral artery) PCOM (Posterior Communicating Artery) AICA (Anterior Inferior Cerebellar Artery) PICA (Posterior Inferior Cerebellar Artery)
9. What does CMAP stand for? Compound Muscle Action Potential Cortical Mapping Cochlear Microphonic Action Potential Ratio Central Monitoring Action Plan
10. What combination of factors have been demonstrated to be predictive of postoperative facial nerve outcomes? Facial Nerve CMAP threshold and Onset Latency The duration of facial nerve spasm and mechanical activation events Facial Nerve CMAP threshold and Proximal to Distal Amplitude Ratio Stability of Wave V on ABR
