To determine the workspace through an anatomical dimensional study of the skull base to further facilitate the design of the robot for endonasal endoscopic transsphenoidal (EET) surgery.
There were 120 cases having a paranasal sinus CT scan in the database. The internal volumes of the nasal cavities (NC), the volumes of the sphenoid sinuses (SS), and the distance between the anterior nasal spine and base of the sellar (d-ANS-BS) were measured.
The Pearson correlation coefficient (PCC) between the relevant distances and the volumes of the right NC was 0.32; between the relevant distances and the volumes of the left NC was 0.43; and between the relevant distances and volumes of NC was 0.41; with a statistically significant difference (p < 0.001). All PCCs had a statistically significant meaningful difference (p < 0.05).
The volume of NCs were significantly correlated with distances (p < 0.05). The safest and shortest distance to guide the robotic arm length in the EET approach could be represented by d-ANS-BS. This result was also used as primary information for further robotic design.
通过对头颅底进行解剖学维度研究来确定工作空间,以进一步推动鼻内镜经蝶窦(EET)手术机器人的设计。
数据库中有120例进行了鼻窦CT扫描的病例。测量了鼻腔(NC)的内部容积、蝶窦(SS)的容积以及前鼻棘与鞍底之间的距离(d-ANS-BS)。
相关距离与右侧NC容积之间的皮尔逊相关系数(PCC)为0.32;与左侧NC容积之间的PCC为0.43;与NC容积之间的PCC为0.41;差异具有统计学意义(p < 0.001)。所有PCC均具有统计学意义上的显著差异(p < 0.05)。
NC的容积与距离显著相关(p < 0.05)。在EET手术入路中,引导机器人手臂长度的最安全、最短距离可以用d-ANS-BS表示。该结果也被用作进一步机器人设计的主要信息。
