This atlas looks at the surgical treatment of the acoustic neurolina. Diagnosis is looked at particularly closely, as surgical strategies are planned according to the anatomic location and growth pattern of these tumours. The preoperative considerations, operating room set-up, patient positioning, and neuronavigational equipment are described for microsurgery in the cerebellopontine angle region. The operative techniques for removing acoustic neurinomas in correlation with size and extension of the tumour are then provided in step-by-step detail; intraoperative photographs are paired with explanatory coloured line drawings. Finally, the tumours of the cerebellopontine angle that may mimic acoustic neurinoma are described.
