【经鼻内镜颅底手术应用解剖学数据采集的初步研究】


**目的**

探讨利用 MicronTracker 双目视觉导航系统在解剖学研究乃至手术过程中测量解剖学标志的可行性，并对经鼻内镜颅底手术的相关解剖学进行研究。

**方法**

我们基于 MicronTracker 双目视觉导航系统设计了一套新型解剖学数据采集系统，用于测量并记录解剖学标志；随后，利用该系统测量了67例成人干颅骨标本（男32例，女35例）中相关平面与重要解剖结构之间的角度及距离。

**结果**

1) 该系统运行可靠，能够实时获取角度和距离数据。2) 主要解剖学标志数据如下：法兰克福水平面相对于额骨平面的俯仰角——男性为 (77.7 ± 4.7) 度，女性为 (81.6 ± 4.5) 度；骨性鼻底相对于额骨平面的俯仰角——男性为 (78.6 ± 5.8) 度，女性为 (82.0 ± 4.5) 度；同侧鼻棘至破裂孔前缘的距离——俯仰角：男性为 (61.3 ± 7.6) 度，女性为 (65.6 ± 7.1) 度；方位角：男性为 (7.0 ± 2.6) 度，女性为 (7.1 ± 1.8) 度；距离：男性为 (68.9 ± 4.1) mm，女性为 (66.3 ± 3.9) mm；同侧鼻棘至蝶窦口的距离——俯仰角：男性为 (40.5 ± 9.3) 度，女性为 (46.4 ± 6.8) 度；方位角：男性为 (2.1 ± 1.8) 度，女性为 (3.6 ± 2.6) 度；距离：男性为 (56.2 ± 3.1) mm，女性为 (53.4 ± 3.0) mm。结论

1) 基于 MicronTracker 双目视觉导航系统的解剖数据采集系统，能够便捷、准确且快速地测量解剖标志点。2) 颅底及鼻腔标志点与额骨平面及矢状面之间的解剖关系稳定；在经鼻内镜颅底手术中，可将上述平面作为基准面，用于定位解剖标志点。

Abstract 

Objective

To explore the feasibility to measure the anatomy landmarks in the anatomy research, even in the operation by the MicronTracker binocular visual navigation system, and to study the anatomy of the transnasal endoscopic surgery of skull base.

Method

We designed a new anatomy data collection system based on the MicronTracker binocular visual navigation system to measure and record the anatomy landmarks, and measured the angles and distances between the related planes and the important structures on 67 dry adult cranium specimens (32 male, 35 female).

Result

1) The system is reliable, the angles and the distances can be acquired in the real time. 2) The major date of the landmarks was the pitch of the Frankfurt horizontal plane according to the frontal bone plane, male: (77.7 +/- 4.7) degrees, female: (81.6 +/-4.5) degrees; the pitch of the bony nasal floor according to the frontal bone plane, male: (78.6 +/- 5.8) degrees, female: (82.0 +/- 4.5) degrees; from the same side of nasal spine to the anterior edge of foramen lacerum, pitch, male: (61.3 +/- 7.6) degrees, female: (65.6 +/-7.1) degrees, azimuth, male: (7.0 +/- 2.6) degrees, female: (7.1 +/- l.8) degrees, the distance, male: (68.9 +/- 4.1) mm, female: (66.3 +/- 3.9) mm; from the same side of the nasal spine to the aperture of the sphenoidal sinus, pitch, male: (40.5 +/- 9.3) degrees, female: (46.4 +/- 6. 8) degrees, azimuth, male: (2.1 +/- 1.8) degrees, female: (3.6 +/- 2. 6) degrees, the distance, male: (56.2 +/- 3.1) mm, female: (53.4 +/- 3.0) mm.

Conclusion

1) The anatomy data collection system based on the MicronTracker binocular visual navigation system can be used to measure the anatomy landmarks conveniently, accurately and quickly. 2) The relationship between the landmarks of the skull base and the nasal cavity and the frontal bone plane and the sagittal plane is stable, and the planes can be used as the datum plane to look for the landmarks in the transnasal endoscopic surgery of skull base.
