Abstract:
Objective To observe the microscopic anatomy structures of petroclival region via the retrosigmoid keyhole approach,then provide an anatomic basis for clinical application.Method Six adult cadaveric heads 6xed by 10% formaldehyde solution were used for simulating the retrosigmoid keyhole approach to observe major microscopic anatomy structures.Results By means of adjusting the microscope,structures such as the ipsilateral trigeminal nerves,cranial nerve,acoustic nerve,posterior nerves,anterior and lateral pons,lateral cerebellar hemisphere,anterior inferior cerebellar artery,vertebral artery,posterior inferior cerebellar artery were exposed via this keyhole approach.Conclusion This retrosigmoid keyhole approach is according with the minimally invasive principle,and represents a reasonable option for accessing the petroclival region.
