摘　　要：髁突外生型骨软骨瘤常采用手术切除,但切除范围多基于术者经验,易导致肿瘤复发或神经血管损伤。本文报道髁突巨大外生型骨软骨瘤1例,采用计算机辅助设计技术(Proplan 1.3软件)术前确定瘤体与髁突关节面边界,模拟设计手术入路、截骨平面及瘤体取出路径,并利用快速成型技术制作数字化截骨导板,于术中应用。该数字化导板可精确指导髁突巨大外生型骨软骨瘤切除并保护未受累髁突软骨面,避免神经血管损伤,节约手术时间。The condylar osteochondroma of exogenous type is usually treated by surgical resection, but the scope of resection is usually based on surgeon’s experience, which leads to a certain risk of recurrence and injuries of important vessels and nerves. We reported a case of a giant condylar osteochondroma of exogenous type, preoperative planning was conducted using computer-aided design（CAD） technique（Proplan 1.3） for determining the boundary between the tumor and the articular surface of condyle, and designing the virtual tumor resection plane, surgical approach and remove-out path of the tumor. Rapid prototyping（RP） technique was used to make osteotomy template based on the preoperative planning. The application of digital template could improve the accuracy of the giant condylar tumor resection and help to preserve the uninvolved condyle. The use of digital template could reduce injuries to the nerves and vessels, as well as save the operation time.
