Slide 1-

Radiation treatment for Acoustic NeurinomaRadiosurgery – high dose, high precision radiotherapy where whole prescribed dose is delivered in single/few fraction CyberKnife/SRS/fSRS Gamma Knife/SRS LINAC/SRS/fSRS
Slide 2-

Radiation treatment for Acoustic NeurinomaRadiosurgery – high dose, high precision radiotherapy where whole prescribed dose is delivered in single/few fraction A total of 55 full-text articles were included in the analysis. All studies were retrospective, except for 2 prospective quality of life studies. Five-year tumour control rates with Gamma Knife radiosurgery (RS), single fraction LINAC RS, or fractionated stereotactic radiation therapy (FSRT) were similar at 81-100%. The single fraction RS series (LINAC or Gamma Knife) with tumour marginal doses between 12 and 14 Gy revealed 5-year tumour control rates of 90-99%, hearing preservation rates of 41-79%, facial nerve preservation rates of 95-100% trigeminal preservation rates of 79-99%
