Abstract：ObjectiveTo explore the technical key points，clinical eficacy and advantage mechanism of resectionofpetroclival region tumorsvianeuroendoscopicfar-lateral supracerebellar infratentorialapproach（EFLSCITA)，soas toprovidereference forclinical practice.MethodsTheclinical dataof7patients with petroclival regiontumors whounderwent surgicalresectionvia EFL-SCITAintheAfiliated Hospitalof XuzhouMedical University from January2O2O to May2O23wereretrospectivelyanalyzed.Theintraoperative technical keypoints and postoperativeeffcacy were analyzed.ResultsAmong the7patients,5 had total tumor resection and2 had subtotal resection.Postoperative pathologyconfirmed2cholesteatomasand5meningiomas.Noneof the7patientssffred from nerve injury，and1 meningioma patient developed cerebellar contusion and edema postoperatively.No deaths occurred.Followed up for 1～2 years，all7 patients lived normally without recurrence.ConclusionsResection of petroclival region tumors via EFL-SCITA has the advantages of minimal trauma，clear vision，and less complications, especiallyinprotecting nervefunctionand improving thetotal tumorresectionrate，whichisworthyofclinical promotion and application.
