摘  要:内镜鼻窦手术是慢性鼻.鼻窦炎患者首选治疗方法,并且在其他鼻窦、眼眶及颅底疾病的处理上正发挥越来越大的作用。尽管先进的鼻内镜和高分辨率的术前CT的应用,但是严重的并发症诸如失明,中枢神经系统的损伤,甚至死亡仍有发生,这是因为内镜鼻窦手术可能受限于解剖结构的复杂性或术中的出血。最近,计算机辅助手术技术已经实现术中解剖结构和术前影像学资料直接对比。在记录和校准之后,术者可以在计算机辅助手术设备支持下指向特定的结构,然后锁定CT影像上该设备顶端的位置。这种计算机辅助手术系统可以获得更精准的手术切除和更高的鼻窦通畅率以及更少的并发症出现的效果雄。笔者把使用计算机辅助手术的经验应用到术中导航中,并且就手术的安全性、持续时间、并发症以及手术结果几方面将它同无导航的手术进行了比较。Endoscopic sinus surgery (ESS) is a treatment of choice for chronic rhinosinusitis (CRS), with an expanding role in the management of other sinus, orbit, and skull base diseases. Despite the availability of excellent nasal telescopes and high-resolution preoperative computed tomography (CT), major complications such as blindness, central nervous system (CNS) trauma, and even death still occur, because the ESS may be compromised by anatomic complexity or intraoperative bleeding. Of late, computer-aided surgery (CAS) technology has permitted a direct comparison of the intraoperative anatomy with preoperative imaging information. After a registration and calibration process, the surgeon may point to a specific structure with the CAS instrument and then view the location of the instrument tip on the CT image. The use of CAS systems may allow for more precise dissections and greater rates of sinus patency outcomes and fewer complications. We describe our experience with CAS as applied to intraoperative guidance and compare it with surgery without imaging guidance, in terms of safety of surgery, duration, complications, and outcome.
