Objective To investigate the pillow next generations microsurgery sigmoid sinus surgery operation of large acoustic neuromas and treatment techniques.Methods Totally 45 patients all have adopted the suboccipital retrosigmoid approach,microsurgical resection of the tumor,14 patients with endoscopic-assisted resection.Results Of the 45 cases,40 cases of total resection,subtotal in 5 cases.Complete resection rate was 88.9%;33 cases of facial nerve function preservation.After hearing loss,or increased in 9 cases,6 cases occurred facial numbness,facial paralysis l1 cases,which were followed up for 6 months to 2 years,6 cases of hearing loss recovery,restore facial numbness,4 cases of facial paralysis recovery in 7 cases.Conclusions The descendants of sigmoid sinus pillow next microsurgical removal of large acoustic neuroma,facial nerve anatomy and function of the protection available,can significantly reduce morbidity and mortality.
