“…Several neurosurgical techniques have been attempted to enhance knowledge and familiarity with certain cranial approaches. Hamamcioglu et al (2008) described a four-step laboratory dissection under the operating microscope of cranial nerves in the posterior fossa. Positioned in the lateral side, a 3x3 cm craniectomy was performed in the ovine skull in the right paramedian suboccipital bone.…”

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.

“…[2][3][4][5][6][7][8] Many articles are reporting on the use of alternatives to live animals in microsurgical training. [2][3][4][5][6][7][8][9][10][11][12][13] We propose a simple fresh sheep cranium model for orbita and optic nerve microsurgical training. The fresh sheep cranium material has been previously described as a useful model to learn microneurosurgical skills [2][3][4]11,14] and we have applied the same model in the current study.…”

Background:Neurosurgery and ophthalmology residents need many years to improve microsurgical skills. Laboratory training models are very important for developing surgical skills before clinical application of microsurgery. A simple simulation model is needed for residents to learn how to handle microsurgical instruments and to perform safe dissection of intracranial or intraorbital nerves, vessels, and other structures.Materials and Methods:The simulation material consists of a one-year-old fresh cadaveric sheep cranium. Two parts (Part 1 and Part 2) were designed to approach structures of the orbit. Part 1 consisted of a 2-step approach to dissect intraorbital structures, and Part 2 consisted of a 3-step approach to dissect the optic nerve intracranially.Results:The model simulates standard microsurgical techniques using a variety of approaches to structures in and around the orbit and the optic nerve.Conclusions:This laboratory training model enables trainees to gain experience with an operating microscope, microsurgical instruments and orbital structures.

“…[1] More realistic models using animals can be associated with ethical problems which vary widely internationally. [2] The fact remains that despite different training models being well described in the literature and apparently available for training purposes in the field of microsurgery, the training situation for residents can hardly described as satisfactory. This educational conflict increases stress experienced by hospital residents and can lower morale in relation to continued microsurgical practice.…”

“…[3] More complex components, such as preparation of tissues, shrinking, suction and clipping techniques can be taught and practiced in an appropriate and realistic manner. [237] There is still a need for realistic models for surgical, and especially microsurgical training, purposes. Complex operations in Neurosciences demand excellent surgical skills in microsurgery to optimise successful treatments for patients in this field.…”
