“…[1][2][3][4][5][6] The primary treatment for COLs is microsurgery, and stereotype radiosurgery is considered for speci c lesions, such as cavernous hemangiomas and meningiomas localized in the cavernous sinus (CS). [7] Senior neurosurgeons advocate that the selection of surgical approaches according to the pathology and location. However, no study has summarized or elucidated the details of surgical approach selection.…”

We aim to share our experience of the removal of COLs, and propose a novel classi cation to guide the approach selection. MethodsWe retrospectively reviewed 45 consecutive patients with COLs who underwent surgery performed by the same neurosurgeon between November 2010 and November 2022. The surgical approach was selected according to the anatomical region classi cation of the COLs. For lesions limited to space A (lateral superior orbital ssure, SOF), the pterion or extended pterion approach (PA or EPA) was used. For lesions limited to space B (extraconal compartment medial SOF, and cavernous sinus CS) and C (intraconal compartment, medial SOF, and CS), the pretemporal transcavernous approach (PTCA) was used. For lesions limited to space D (intraconal compartment and optic canals), the subfrontal approach (SA) was used. For lesions extending into the infratemporal fossa (ITF), the cranio-orbito-zygomatic approach (COZA) was used. For lesions involving pterygopalatine fossa (PPF), the endoscopic transnasal approach (ETNA) was used. We analyzed the clinical manifestations, imaging data, surgical approaches, surgical outcomes, neurological outcomes, and follow-up data. ResultsGross total resection was performed in 35 patients (35/45, 77.8%). SA, PA, EPA, PTCA, COZA, and ETNA were performed in 9, 9, 10, 10, 6, and 1 case(s), respectively. Progression of the residual tumor was observed in 6 cases (1 adenoid cystic carcinoma and 5 meningiomas). ConclusionSurgical approach selection plays a vital role in patient prognosis. This novel classi cation based on the involvement of anatomic space could help surgeons select an appropriate approach to remove the COLs.
