As a result of technological advances, 3D-navigation systems are playing an increasingly important role in paranasal sinus and anterior skull base surgery.
The BrainLAB Kolibri navigation system (BrainLAB, Heimstetten, Germany) was used in the surgical management of chronic sinusitis and nasal polyposis in 35 patients. Surgery was performed under local anaesthesia. In order to compare this technique with traditional methods, 35 additional patients underwent conventional surgery. A clinical plausibility test using specific anatomical landmarks was performed to evaluate intraoperative navigation accuracy. In addition, a standardised questionnaire was used to document setup and registration times. Standardised rating scales helped assess whether the system can make surgery safer.
It took approximately 5.8 min to set up the navigation system. The time required for system and patient positioning, including the attachment of the headband, was 4.2 min on average. Patient registration with the z-touch system was completed after an average of 4.2 min. It took an average of approximately 8.1 min to register a patient using the soft-touch system. The use of the navigation system increased the total time for preparation and surgery by approximately 50% in comparison to the conventional technique. An average accuracy of 1.5-2.3 mm in all three planes was measured. Participating surgeons felt that the system made surgery considerably safer.
The BrainLAB Kolibri navigation system offers good accuracy, a short setup time and an easy registration technique. The combination of these qualities and intuitive operation make this system a suitable option for routine use in paranasal sinus surgery. As a result of its compactness, the BrainLAB Kolibri navigation system can be moved easily between different operating rooms and can also be used in small facilities (e.g. container operating theatres in field hospitals).
由于技术进步，三维导航系统在鼻窦和前颅底手术中发挥着越来越重要的作用。
采用BrainLAB Kolibri导航系统（德国海姆斯泰滕的BrainLAB公司）对35例慢性鼻窦炎和鼻息肉患者进行手术治疗。手术在局部麻醉下进行。为了将该技术与传统方法进行比较，另外35例患者接受了传统手术。使用特定解剖标志进行临床合理性测试，以评估术中导航准确性。此外，使用标准化问卷记录设置和注册时间。标准化评分量表有助于评估该系统是否能使手术更安全。
设置导航系统大约需要5.8分钟。系统和患者定位所需时间，包括头带的附着，平均为4.2分钟。使用z-touch系统平均4.2分钟完成患者注册。使用软触摸系统注册患者平均约需8.1分钟。与传统技术相比，使用导航系统使准备和手术的总时间增加了约50%。在所有三个平面上测得的平均精度为1.5 - 2.3毫米。参与手术的外科医生认为该系统使手术更安全。
BrainLAB Kolibri导航系统具有良好的准确性、较短的设置时间和简便的注册技术。这些品质与直观的操作相结合，使该系统成为鼻窦手术常规使用的合适选择。由于其紧凑性，BrainLAB Kolibri导航系统可以在不同手术室之间轻松移动，也可用于小型设施（如野战医院的集装箱手术室）。
