Abstract：Objective To investigate the clinical features and treatment of trapped temporal horn(TTH)after resection of tumors in the lateral ventricular trigone.Methods The clinical data of 48 patients with tumors in the lateral ventricular trigone treated by microsurgery from March 2015 to March 2022 were retrospectively analyzed.Results TTH occurred in 12 patients(25.0%),of whom,7 patients had tumors with a maximum diameter of≥4.0 cm,8 patients(66.7%)used hemostatic materials during surgery,11 patients(91.7%)had cerebral aqueduct syndrome after surgery,9 patients(75.0%)had midline shift,3 patients had external ventricular drainage after surgery.The onset time ranged from 7 days to 10.5 months,with a median of 3.5 months;9 patients(75.0%)had delayed TTH.Five patients were treated conservatively;7 patients underwent surgery(4 ventriculoperitoneal shunt,1 external ventricular drainage,1 craniotomy and craniectomy,1 ventriculoperitoneal shunt after endoscopic third ventriculostomy failure),and the symptoms of increased intracranial pressure were relieved after surgery.The patients were followed up for 1.2～5.5 years after discharge,with a median of 2.7 years;all patients showed improvement in symptoms and no recurrence was observed.Conclusions Most TTH are delayed after resection of tumors in the lateral ventricular trigone.Mild TTH should be followed up with CT or MRI.If symptoms of increased intracranial pressure occur,surgery is recommended.
