Abstract

Context

The objective was to evaluate the feasibility and usefulness of a new 3D printed simulator for endoscopic pituitary surgery. This simulator was used at the Pituitary Workshop, a French theoretical and practical course designed to teach the basics of pituitary tumour management.

Methods

We conducted a cross-sectional study. The pituitary workshop had two components: (i) hands-on skills lab on the simulator, and (ii) lecture-based learning. The simulator was assessed by scoring its realism (face validity, score out of 80), its effectiveness in improving participants’ surgical technique (content validity, score out of 60), and its ability to differentiate levels of skill competence using performance metrics (construct validity, score out of 12). In a subgroup of 9 participants, the impact of the theoretical component of the course was also assessed (score out of 33), using a knowledge questionnaire before and after the course.

Results

Participants were neurosurgery residents (n = 24) and board-certified neurosurgeons (n = 6), supervised by expert neurosurgeons (n = 3). Face and content validity scores were high, reaching 63.3 ± 8.4 and 55.7 ± 4.6 respectively. Performance scores were higher in the group of experts and board-certified neurosurgeons than in the group of residents (12 ± 0 and 11.3 ± 1.2 vs. 9.2 ± 2.3, P = 0.019). The knowledge score improved significantly after the workshop (25.5 ± 4.8 vs. 10.9 ± 5.8, P = 7.1e-05).

Conclusions

Based on the face, content and construct validity scores, simulation training using the new model can be considered feasible and useful for neurosurgery residents. The pituitary workshop has a positive practical and theoretical impact on the majority of participants.

期刊介绍： Neurochirurgie publishes articles on treatment, teaching and research, neurosurgery training and the professional aspects of our discipline, and also the history and progress of neurosurgery. It focuses on pathologies of the head, spine and central and peripheral nervous systems and their vascularization. All aspects of the specialty are dealt with: trauma, tumor, degenerative disease, infection, vascular pathology, and radiosurgery, and pediatrics. Transversal studies are also welcome: neuroanatomy, neurophysiology, neurology, neuropediatrics, psychiatry, neuropsychology, physical medicine and neurologic rehabilitation, neuro-anesthesia, neurologic intensive care, neuroradiology, functional exploration, neuropathology, neuro-ophthalmology, otoneurology, maxillofacial surgery, neuro-endocrinology and spine surgery. Technical and methodological aspects are also taken onboard: diagnostic and therapeutic techniques, methods for assessing results, epidemiology, surgical, interventional and radiological techniques, simulations and pathophysiological hypotheses, and educational tools. The editorial board may refuse submissions that fail to meet the journal''s aims and scope; such studies will not be peer-reviewed, and the editor in chief will promptly inform the corresponding author, so as not to delay submission to a more suitable journal. With a view to attracting an international audience of both readers and writers, Neurochirurgie especially welcomes articles in English, and gives priority to original studies. Other kinds of article - reviews, case reports, technical notes and meta-analyses - are equally published. Every year, a special edition is dedicated to the topic selected by the French Society of Neurosurgery for its annual report.
