To evaluate the efficacy and safety of trans-sulcal or fissure approach in surgical treatment of supratentorial lesions Retrospective clinical case series This study included 42 patients. Age ranged from 4 to 78 years. Sulcal dissection was done in 26 patients at or near the eloquent areas, and in 16 patients, it was done in non-eloquent areas. Diffusion tensor tractography, neuronavigation, and intraoperative monitoring were applied for lesions at the motor areas. The follow-up period was 24 months. Gross total excision could be achieved in 52% of patients. Sulcal dissection was easy in 26 patients with the lax brain. The outcome, according to the Karnofsky scale, was 100 in 21/42 (50%). Complications were transient deterioration of function in three patients, and immediate post-operative hemorrhage in two patients. Three patients became seizure-free after surgery. The trans-sulcal dissection is a safe, useful, and applicable approach. Through which it is possible to reach deeply seated lesions. It preserves the motor functions, provides wider exposure, minimizes the need of brain retraction during surgery, and preserves the gyral layers. Complications are usually transient, specially in the presence of preoperative diffusion tensor tractography, intraoperative neuronavigation, and monitoring.

经舌沟或裂隙入路治疗上上脑部病变：评估

评估经舌沟或裂隙入路方法治疗幕上病变的有效性和安全性回顾性临床病例系列这项研究包括42例患者。年龄从4到78岁不等。在雄辩区或附近的26例患者中进行了根除术，在非雄辩区中的16例中进行了。对运动区的病变进行了弥散张量束缚术，神经导航和术中监测。随访期为24个月。52％的患者可以完成总切除。26例大脑松弛的患者容易进行颅脑夹层清扫术。根据Karnofsky量表，结果为21/42中的100（50％）。并发症是三例患者的功能暂时性恶化，以及两名患者的术后立即出血。手术后三例患者无癫痫发作。经鼻腔解剖是一种安全，有用和适用的方法。通过它可以到达深处的病变。它保留了运动功能，提供了更宽的暴露范围，最大程度地减少了手术期间大脑收缩的需要，并保留了回旋层。并发症通常是短暂的，特别是在术前弥散张量束线图，术中神经导航和监测的情况下。
