      Acute sensorineural hearing loss in patients with vestibular schwannoma early after cyberknife radiosurgery.
      ] regarding acute sensorineural hearing loss in patients with vestibular schwannomas (VS) early after fractionnated Cyberknife radiosurgery (RS). The reported prevalence was 8.6% as considered in the first 6 months after RS. Hearing improvement was noted in only one patient after 3 months time. The authors postulate that this is related to damage to the cochlear nerve. Furthermore, they postulate that tumors measuring less than 1.45 cm with serviceable hearing should be observed. For larger tumors, including medium-size ones, RS should be considered the first line therapy.
