Accessing intra- and extradural tumors via an endonasal approach requires working safely in a relatively narrow area with unobstructed visibility. The authors describe their experience to highlight the utility of a side-cutting aspiration device for endoscopic endonasal resection of skull base tumors.
The authors used this device in 13 nonconsecutive endoscopic endonasal procedures for different skull base tumors (8 pituitary macroadenomas, 2 craniopharyngiomas, 1 chordoma, 1 recurrent ependymoma, and 1 lymphoma). Illustrative cases and video are presented to demonstrate its use.
The instrument was easy to use and effective in the removal of the lesions presented in this series. In 10 patients (77%), gross-total resection was possible; in the other 3 patients (23%), more than 80% of the tumor was resected. No collateral tissue damage or any other complication resulted from device-related debulking or aspiration.
The side-cutting tissue resector is a safe, easy to use, and effective tool for internal debulking and extracapsular dissection of nonvascularized tumors that are too firm for bimanual suction or blunt ring curette dissection. It is particularly useful when working through a deep and narrow corridor such as is encountered in endoscopic endonasal skull base surgery.
经鼻内入路进入颅内和硬脊膜外肿瘤，需要在相对狭窄的区域内安全操作，并保持无障碍的可视性。作者描述了他们的经验，以强调侧切吸引装置在经鼻内镜颅底肿瘤切除术的实用性。
作者在 13 例非连续的经鼻内镜颅底手术中使用了该设备，用于治疗不同的颅底肿瘤（8 例垂体大腺瘤、2 例颅咽管瘤、1 例脊索瘤、1 例复发性室管膜瘤和 1 例淋巴瘤）。通过病例说明和视频演示来展示其使用方法。
该器械易于使用，在本系列病例中对病变的切除效果良好。在 10 例患者（77%）中实现了大体全切除；在另外 3 例患者（23%）中，切除了超过 80%的肿瘤。由于器械相关的切除术或抽吸术，没有导致任何的组织损伤或其他并发症。
侧切式组织切除器是一种安全、易于使用且有效的工具，可用于对非血管性肿瘤进行内部减容和囊外解剖，对于过于坚硬而无法进行双手抽吸或钝环刮匙解剖的肿瘤尤其有用。在经鼻内镜颅底手术中遇到的深部和狭窄的通道中，它特别有用。
