Abstract:
Objective To discuss the surgical method of resection of petroclival tumors used temporal base transtentorial approach.Methods Analyzed 26 cases of petroclival tumors.All of them were surgically treated under intraoperative neurophysiological monitoring by temporal base transtentorial approach.Firstly the supratentorial part of tumors were resected by pieces,and then the tentorium was cut open,in order to resect residue of the subtentorial part of tumors.This surgical maneuver was applied to reduce the retraction to surrounding vessels,nerves and brain stem,as well to protect important structures and to finally achieve radical removal of the tumors.The efficacy and complications were observed.Results Among 26 cases,19 cases (73.1％,19/26) achieved total removal,5 cases (19.2 ％,5/26) achieved subtotal removal and 2 cases (7.7％,2/26) achieved great partial removal.There was no surgery-related death.Eleven cases suffered from partial neurological deficit.All cases were followed up for 3 months to 4 years,3 cases underwent complete recovery,4 cases underwent partial recovery,and 4 cases underwent permanent deficit.Conclusions Using temporal base transtentorial approach to resect petroclival tumors is convenient,applicable,safe and with minimal injury and with high proportionality of total resection.Under intraoperative neurophysiological monitoring,this approach may be an ideal choice for surgical treatment of these tumors.
