“…Apart from temporal bone dissection, all current animal neurosurgical procedures were reviewed. Techniques such as temporal bone drilling, although valuable to the neurosurgeon, are mostly used in ENT training courses and vary from training on chicken eggs [56] to 3D printed models [57]. Swine models are frequent examples in this kind of technique [58], and sheep temporal bones have also been used [59], but there is a multitude of experimental designs that have proven their utility.…”

Introduction. Due to its high complexity, neurosurgery consists of a demanding learning curve that requires intense training and a deep knowledge of neuroanatomy. Microsurgical skill development can be achieved through various models of simulation, but as human cadaveric models are not always accessible, cadaveric animal models can provide a reliable environment in which to enhance the acquisition of surgical dexterity. The aim of this review was to analyse the current role of animal brains in laboratory training and to assess their correspondence to the procedures performed in humans. Material and methods. A Pubmed literature search was performed to identify all the articles concerning training cranial and spinal techniques on large animal heads. The search terms were 'training model' , and 'neurosurgery' in association with 'animal' , 'sheep' , 'cow' , and 'swine'. The exclusion criteria were articles that were on human brains, experimental fundamental research, or on virtual simulators. Results. The search retrieved 119 articles, of which 25 were relevant to the purpose of this review. Owing to their similar neuroanatomy, bovine, porcine and ovine models prove to be reliable structures in simulating neurosurgical procedures. On bovine skulls, an interhemispheric transcalosal and retrosigmoid approach along with different approaches to the Circle of Willis can be recreated. Ovine model procedures have varied from lumbar discectomies on sheep spines to craniosynostosis surgery, whereas in ex vivo swine models, cadaveric dissections of lateral sulcus, median and posterior fossa have been achieved. Conclusions. Laboratory training models enhance surgical advancements by familiarising trainee surgeons with certain neuroanatomical structures and promoting greater surgical dexterity. The accessibility of animal brains allows trainee surgeons to exercise techniques outside the operating theatre, thus optimising outcomes in human surgical procedures.

“…16 Temporal bone dissection grading instruments have been established, including the Welling Scale. 17 Traditionally, temporal bone laboratory practice was limited to cadaveric bones; however, as technology advances, adjunctive training devices continue to improve, 18 including 3-dimensionally printed bone, 19,20 virtual reality (VR) drilling, [20][21][22] a chicken egg, 23 and a virtual temporal bone dissection simulator. 24 Technical skills in mastoidectomy were transferable from the VR simulation environment to cadaveric dissection with significant improvement in performance after directed, self-regulated training in the VR temporal bone simulator.…”

Objectives To describe the impact of resident involvement in tympanoplasty on operative time and surgical complication rates. Study Design Case series with chart review. Setting Tertiary medical center. Subjects and Methods Current Procedural Terminology codes were used to identify patients in the 2011-2014 public use files of the American College of Surgeons National Surgical Quality Improvement Program who underwent a tympanoplasty or tympanomastoidectomy. Cases were included if the database indicated whether the operating room was staffed with an attending alone or an attending with residents. Categorical and continuous variables were compared with chi-square, Fisher's exact, and Mann-Whitney U tests. Generalized linear models with a log-link and gamma distribution were used to examine the factors affecting operative time. Results Overall, 1045 cases met our study criteria (tympanoplasty, n = 797; tympanomastoidectomy, n = 248). Resident involvement increased mean operative time for tympanoplasties by 46% (107 vs 73 minutes, P < .001) and tympanomastoidectomies by 49% (175 vs 117 minutes, P < .001). While controlling for confounding factors, the variable with the largest impact on operative time was resident involvement. There were no significant differences observed in the rate of surgical complications between attending-alone and attending-resident cases. Conclusion Resident involvement in tympanoplasty and tympanomastoidectomy did not affect the surgical complication rate. Resident involvement increased operative time for tympanoplasties and tympanomastoidectomies; however, the specific reasons for the increase are not explained by the available data.

“…Temporal bone laboratory is relevant to the otologic surgeons and residents. Simulation is a mandatory component of surgical training (Mowry and Hansen, 2014; Meléndez García et al., 2014). However, setting up a temporal bone laboratory can be very expensive, especially because of the high costs of an operating microscope or endoscopic equipment (rigid endoscope, light source, camera, and monitor).…”

New low-cost magnifying device for temporal bone laboratory

et al. 2019

Temporal bone dissection has important role in educating and training oto and skull base surgeons. Mounting of a temporal bone laboratory is expensive. A dedicated magnifying system, such as a surgical microscope or an endoscopic equipment, represents one of the most significant costs. The aim of this study is to test and demonstrate the utility of a commercial USB as a low-cost solution to equip the laboratory with a good magnifying system and illumination.
