text: Yo, check it out, here's the lowdown, listen close
  Intracanalicular vestibular schwannomas, IVS they pose
  They make up 8% of vestibular schwannomas, yo
  MRI's on the rise, making detection grow
  
  Radiosurgery, a method in the mix
  For treating IVS, but some risks persist
  This study's aim, yo, to analyze the game
  Tumor control and hearing, see if they remain
  
  We dug through 14 papers, PubMed, that's the source
  Assessed the tumor volume, enhanced scans, of course
  Hearing preservation, we used the GR class
  Gardner-Robertson classification, yo, it's a blast
  
  Our stats were on point, IBM SPSS our tool
  Tumor growth controlled, IVS ain't no fool
  Radiosurgery outperformed the wait-and-see
  Hearing preservation, wait and see, it's just as key
  
  Low risk of facial nerve dysfunction, that's what we found
  Radiosurgery, the treatment, holdin' it down
