“…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. A very insightful review on this topic was published by Bergin et al [60] which identified 11 animal models that can be used for middle ear surgery, as well as Wiet et al [61] who researched otologic training models.…”

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.

ZusammenfassungAkzidentelle Verletzungen mit einer Kettensäge betreffen oftmals den Oberschenkel, den Kopf und die Finger. Verletzungen des Unterschenkels sind vergleichsweise seltener. Im Rahmen einer rechtsmedizinischen Beurteilung derartiger Vorfälle ist neben der unmittelbaren, tatsächlichen Verletzungsbeurteilung v. a. die Rekonstruktion des Tathergangs essenziell. Es gilt hier, besonders die Vortäuschung eines Unfalls und somit eine Selbstbeibringung auszuschließen bzw. zu bestätigen.Ausgehend von einem Fallbeispiel werden in der vorliegenden Arbeit die rechtsmedizinischen und wundmorphologischen Aspekte von Verletzungen mit einer Kettensäge analysiert und im Rahmen von experimentellen Vergleichsversuchen mit dem Verletzungsbild durch ein Messer und eine Glasscherbe verglichen.Mit einer Stihl-MSA-160C-Motorsäge wurden an einer Schweinekeule mehrere Schnitte gesetzt und diese hinsichtlich ihrer Morphologie Vergleichsschnitten eines Küchenmessers und einer Glasscherbe gegenübergestellt.Anhand spezifischer Wundmerkmale, der Schnittführung sowie der Überwindung des Sicherheitsschalters bei entsprechender Griffhaltung der Säge konnte im aktuellen Fall die Verletzung zweifelsfrei einem Unfallgeschehen zugeordnet werden.
