The Cavitron Ultrasonic Surgical Aspirator (CUSA System) has been used at our institution in the resection of carcinoma of the tongue in 10 patients. This device is an ultrasonically powered aspirator that selectively fragments and aspirates tissue within a 1- to 2-mm radius of its tip. The technique used in our unit in tongue surgery was to incise the touch mucosal capsule of the tongue with electrocautery, and then to divide muscle and skeletonize blood vessels using the CUSA System. Smaller vessels, up to 2 mm in size, were cauterized directly by the friction created at the tip of the instrument. In this way, excellent control was available at all times and blood loss was consequently minimal. As our experience in the use of the CUSA System increased, blood loss was virtually eliminated, anatomic landmarks were more easily defined, and at no stage did any tongue necrosis occur in any of the patients of the series.
在我们机构，10例舌癌切除术使用了Cavitron超声手术吸引器（CUSA系统）。该设备是一种超声驱动的吸引器，能在其尖端半径1至2毫米范围内选择性地破碎并吸除组织。我们科室在舌部手术中采用的技术是先用电灼切开舌的触觉黏膜包膜，然后使用CUSA系统分离肌肉并使血管骨骼化。直径达2毫米的较小血管则通过器械尖端产生的摩擦直接烧灼。通过这种方式，始终能实现良好的控制，因而失血极少。随着我们使用CUSA系统经验的增加，几乎实现了无出血，解剖标志更易于界定，且该系列患者中无一例在任何阶段出现舌坏死。
