Abstract

Objective: Visuo-spatial ability (VSA) plays a role in preoperative planning, anatomical navigation and decision-making during surgery. This study aimed to test hypothesis that a correlation link existed between VSA and the speed of execution of a complex surgical task.

Method: The study was carried out on 49 students just before starting their surgical internship, at Lille Medical Faculty in October 2023. They answered a biographical questionnaire including confounding factors on VSA, then completed the Mental Rotation Test - A (MRT-A). They were timed on two separate tasks: conforming a titanium plate to mandibular angles on a 3D printed model, and excising a lesion from the helix of a silicone cast ear model, followed by a reconstruction using a "small ear" flap.

Results: A weak correlation between the MRT-A score and the time required to complete the right and left plates conformation (r = -0.377, p = 0.007; r = -0.349, p = 0.014 respectively). There was a moderate correlation between the MRT-A score and the time required to complete the entire plate conformation workshop (r = -0.457, p = 0.001). There was no significant correlation between the MRT-A score and the time required to complete the ear workshop (r = -0.127; p = 0.375). A significant regression equation was found [F(2,48) = 104.960; p < 0.0001)], with a R² of 0.814.

Conclusion: A correlation was found between VSA and the speed of a conformation of titanium plate on mandibular angle, but no link was established between speed and performance of a complex surgical task on flapless excision suture workshop.

期刊介绍： Since its establishment in 2003, The Surgeon has established itself as one of the leading multidisciplinary surgical titles, both in print and online. The Surgeon is published for the worldwide surgical and dental communities. The goal of the Journal is to achieve wider national and international recognition, through a commitment to excellence in original research. In addition, both Colleges see the Journal as an important educational service, and consequently there is a particular focus on post-graduate development. Much of our educational role will continue to be achieved through publishing expanded review articles by leaders in their field. Articles in related areas to surgery and dentistry, such as healthcare management and education, are also welcomed. We aim to educate, entertain, give insight into new surgical techniques and technology, and provide a forum for debate and discussion.
