  • Title: How I do it? Resection of residual petrous apex chordoma with combined endoscopic endonasal and contralateral transmaxillary approaches.
    Author: Shen M, Shou X, Zhao Y, Wang Y.
    Journal: Acta Neurochir (Wien); 2022 Jul; 164(7):1967-1972. PubMed ID: 35616736.
    Abstract:
    BACKGROUND: The petrous apex is one of the most challenging areas of the skull base to access. METHOD: We present a case of residual petrous apex chordoma posterolateral to the paraclival segment of the internal carotid artery (ICA) resected with combined endoscopic endonasal and contralateral transmaxillary (CTM) approaches, without lateralization of the ICA. CONCLUSION: This case demonstrates the value of the CTM corridor in resecting petrous apex lesions that are posterolateral to the paraclival segment of the ICA.
