“…This approach was first popularized in 1961 by Drake 16 for surgical treatment of aneurysms of the upper third of the basilar artery, and it has been recognized as the best approach to reach pathologies involving the ambient cistern and middle incisural space. 7,9 It is also an alternative route for selective amygdalohippocampectomy in patients with medically refractory epilepsy. [8][9][10][11] Data comparing the different surgical corridors to remove temporal horn tumors in the literature are lacking.…”

INTRODUCTION: Purely temporal intraventricular tumors are uncommon. Given their deep location, access to these brain tumors can be challenging in terms of preserving brain tissue. The subtemporal approach spares the lateral temporal cortex and is a less traumatic corridor to reach intraventricular temporal tumors. OBJECTIVE: To describe and assess the feasibility of the subtemporal transcollateral approach for the removal of a temporal horn tumor. METHODS: We describe the subtemporal transcollateral sulcus operative technique detailed step-by-step and depicted through both video and illustrations to surgically resect a left intraventricular temporal mass in a 44-year-old woman who presented with worsening memory deficits. The surgery was performed under general anesthesia and with the use of a microscope and neuronavigation. RESULTS: The patient did not suffer from any postoperative complications. Her vision was intact, and her memory deficit was unchanged. A brain MRI showed complete removal of the tumor. The pathological examination revealed a World Health Organization grade I meningioma. CONCLUSION: The subtemporal transsulcal approach seems to be an efficient and safe way to access intraventricular lesions within the temporal horn while avoiding any disruption of the optic radiations and temporal language areas.

BACKGROUND Midbrain and surrounding areas are among the most difficult regions to surgically approach in neurosurgery. The subtemporal approach is a well-known neurosurgical approach that is rarely described in children. OBJECTIVE To assess the feasibility, advantages, and disadvantages of subtemporal approach in children. METHODS A total of 20 pediatric patients with intra-axial tumors involving the lateral midbrain or superior cerebellar peduncle or with extra-axial tumors in the middle incisural space/Meckel cave underwent subtemporal transtentorial approaches with the aim to remove (16 cases) or biopsy (4 cases) their lesions. These cases were retrospectively reviewed and the surgical approach described. RESULTS Total resection was achieved in 11 patients. In the 4 patients who underwent biopsies, a diagnosis was obtained. A total of 5 patients presented non-neoplastic lesions (dermoid tumors or cavernomas). A total of 9 patients harbored low-grade tumors and 6 high-grade tumors. Patients with low-grade tumors and non-neoplastic lesions are all alive with no evidence of disease or stable residue. Four patients affected by high grade tumors died. No patient suffered permanent neurological deficits related to the surgical approach. Three patients presented temporary neurological deficits following the procedure: one case of strabismus, one case of aphasia and hemiparesis, secondary to delayed, transient thrombosis of the Labbé vein, and 1 case of trigeminal neuralgia. CONCLUSION The subtemporal approach represents a feasible approach for mesencephalic and perimesencephalic lesions in children. It provides an ample and direct access, with excellent outcomes and acceptable postoperative morbidity.
