Myocardial injury after noncardiac surgery is significantly related to postoperative 30-day mortality. Trigeminal cardiac reflex is one of the main causes of perioperative cardiac emergency. Therefore, the investigators' aim is to test the hypothesis that trigeminal cardiac reflex associates postoperative myocardial damage in participants undergoing skull base tumor surgery. The investigators will observe the association between trigeminal cardiac reflex and myocardial injury by measuring the concentration of plasma high sensitivity cardiac troponin (hs-cTnT) in participants after skull base tumor surgery.

The incidence of postoperative myocardial injury
the elevation of plasma high sensitivity cardiac troponin I (hs-cTnI) caused by myocardial ischemia or injury (exclude other causes such as sepsis, pulmonary embolism, atrial fibrillation, etc). The blood samples before and within 24 hours after operation will be collected and measured by Roche's fourth generation hs-cTnI. It is commonly defined as an elevation as any value above the 99th percentile upper reference limit for each specific troponin I assay
Time frame: Postoperative 1 day.
