Anatomical Study and Clinical Application of Neuroendoscopic Transfarlateral Supracerebellar Infratentorial Approach.
Journal of Craniofacial Surgery 2023 November
BACKGROUND: Tumors in the petroclival region have challenged neurosurgeons. However, neuroendoscopy has been increasingly applied internationally. This study simulated a pure neuroendoscopic transfarlateral supracerebellar infratentorial approach for petroclival tumor resection from the cadaveric head and discussed the advantages and safety of this approach.
METHODS: The anatomical structure for petroclival tumor resection was visualized using a pure neuroendoscopic transfarlateral supracerebellar infratentorial approach in 5 cadaveric heads. Ten cases with petroclival tumors were retrospectively analyzed and summarized between January 2020 and June 2021. All the cases had undergone surgery using a pure neuroendoscopic supracerebellar infratentorial approach.
RESULTS: The anatomical structure of the petroclival region was exposed using the pure neuroendoscopic supracerebellar infratentorial approach, and the partial anatomical structure of the middle skull base was further exposed by incision of the tentorium in the cadaveric head. Among the 10 cases, the tumors of 6 cases were totally removed, and those of 4 cases were subtotally removed; no cases of intracranial infection or death occurred after surgery.
CONCLUSION: The neuroendoscopic transfarlateral supracerebellar infratentorial keyhole approach is a safe and effective surgical method to treat petroclival lesions and invasive middle cranial fossa lesions.
