Background: Surgical approaches to the posterior fossa are always challenging and complex anatomical structures pose risks for removal of cerebellar lesions.In this study, we aimed define a safe corridor tumor surgery neurosurgeons by examining anatomy cerebellaris in detail measuring some osseous landmarks. Materials Methods:In 15 dry bone craniums 8 cadavers were morphometrically examined distances between important bony landmarks measured with digital caliper millimeter precision.The measurements compared using statistical methods. Results:The distance anterior margin foramen magnum (FM) spheno-occipital synchondrosis (SOS) was found be longer skull than cadaver measurements, statistically significant difference found.There no right left side comparisons for.jugulare, for.magnum, porus acousticus internus canalis nervi hypolossi both samples. Conclusion:Longer border FM SOS make difficult surgical approach clivus lesions, but facilitate reach tumors.Careful preoperative evaluation provides good knowledge dealing such lesions.
