Using of the chicken wing's bone in the microneusurgical training model for microdrilling

Abstract

Background and Objective:Repetitive practicing of microneurosurgical techniques in experimental laboratory using real surgical instruments on training models is extremely important before starting the real surgical interventions. The modeling of the surgical steps with creating of suitable laboratory models is also another important issue in the successfully gaining of microneurosurgical practice.Materials and Methods:In this experimental study, it was created a laboratory training model for microneurosurgical drilling of cranial bones including the close location with the neural and vascular structures. All steps of this study were performed under the operating microscope. Twenty-five fresh chicken wings obtained from supermarket were used for this study. The difficulty and suitability of the model was evaluated in terms of the usability in the training of microneruosurgical microdrilling. Difficulty of the procedure was divided as three degree (very easy, easy, and difficult). The objective criterion for the evaluation of the difficulty of the procedure was the protection of the neurovascular and muscular structures during the procedure.Results:The suitability of the procedure was also evaluated within three groups as bad, good, and perfect. In four (16%) chicken wing's bone, the difficulty of the microdirilling was evaluated as difficult. Fifteen (60%) of the chicken wing's bones were microsurgically drilled with easy procedure. The remaining six (24%) of the wing's bone microdrilling was evaluated as very easy procedure. The suitability of the model was evaluated as bad in three (12%) of the chicken wing's bone. The suitability was found as good in 16 (64%) of the bones. In the remaining three (24%) of the chicken wing's bone microdrilling, the suitability of the model was evaluated as perfect.Conclusion:Microsurgical drilling of the chicken wing's bone without any vascular and muscular injury is accepted as the indication of the successfully surgical microdrilling process. Consolidation of the surgical practice in a laboratory setting, grasping and using of microsurgical instruments, can be repeated in several times in this model. We believe that this model will contribute to the practical training of microneurosurgery.

Validated specialty‐specific models for multi‐disciplinary microsurgery training laboratories: a systematic review

“…For example, neurosurgical models of aneurysm clipping permit trainees to become accustomed to the use of the Yasargil clips, which are now used infrequently due to the advent of embolization technologies but require a high level of technical aptitude in order to achieve satisfactory aneurysm control 13,15 . The use of other specialty‐specific equipment that may be practiced via simulation includes neurosurgical/otolaryngology drills, 8,16,17 microlaryngeal tools such as left and right angled blunt elevators, 18 heart‐shaped forceps or lasers, 19 and venous couplers in Plastic Surgery 20 . In disciplines where microscopic and endoscopic magnification may be used interchangeably, for example Otolaryngology/Head & Neck surgery, microsurgical models exist that also allow for endoscopic visualization 21 .…”

Use of a Contest Format for Objective Assessment of Microsurgical Technique: An Observational Study

“…Many surgical education studies [1][2][3] have pointed out that effective surgical training can reduce technical errors. Various methods for evaluating surgical techniques have been reported 1,[4][5][6][7] in many fields such as gynecology, laparoscopy, and general surgery. In these reports, 8,9 evaluation tables, 3,8 differences between video evaluation and direct evaluation, and evaluation task contents 10,11 were examined; however, there are no reports on the results of objective evaluations repeated over a number of years.…”
