“…The lamb’s head has been widely used in endoscopic sinus surgery, and its similarity to human anatomy has been well documented [9–11]. However, validation of the lamb’s head for surgical training is recent, and was established in a study by measuring the performance of different groups (medical students, residents with varying levels of expertise, and experienced surgeons) in a single dissection [12].…”

ObjectiveTo describe and standardize a reproducible, viable, low-cost lamb’s head model for endoscopic sinus surgery training.MethodsOtorhinolaryngology residents performed the following three endoscopic sinus surgeries using the lamb’s head model: inferior turbinectomy, bullectomy, and maxillary antrostomy. Each student dissected 10 specimens before training these procedures on human patients, and the benefit of the animal model training was evaluated.ResultsNineteen resident physicians of comparable academic level participated in training. All participants agreed that the lamb’s head model dissections improved their skills in using surgical and videoendoscopic instruments, 90% agreed that the dissections improved their confidence with respect to training in human patients, and all stated they would recommend the same training to future residents.DiscussionLamb’s heads have been used for training in endoscopic sinus surgery. However, no standardization of this training had been performed to ensure that it is a valuable tool for learning and skill-building. The standardized method described in this study increased resident physicians’ skills and confidence before beginning their training on human patients. Moreover, our results demonstrate the feasibility of the model, considering its low cost and reproducibility.ConclusionFuture studies with this model should be conducted to assess whether the resulting increase in skills prevents and reduces medical errors, increases patient safety, reduces surgical costs, and improves the quality of otorhinolaryngological care.

“…Our first step, eighteen years ago, when we started with lamb's head model, was detailed studying of the lamb's head surgical anatomy in cooperation with the academic stuff of the Department of Anatomy at the Veterinary Faculty in Zagreb [2]. Second, during two decades of the experience with the lamb's head, we do know that it offers the possibility of training not only septal surgery, middle antrostomy, ethmoidectomy and frontal sinus most anterior and most medial chamber presentation, but also more demanding and advanced procedures in human endoscopic sinus surgery (ESS) such as endoscopic endonasal orbital decompression [3], Draf 1, 2 and 3 procedures [4], cerebrospinal fluid (CSF) leak repair, including the nasoseptal flap [5] , and endonasal endoscopic dacryocystorhinostomy [6]. Besides, eight years ago a special head holder was projected by an architect, and later on produced by Karl Storz, Germany .…”

Background: One of the major challenges of cranial base surgery is reconstruction of dural defects and cerebrospinal fluid leak closure. Various grafting methods have been used for smaller skull base defects with great success. The indications for endoscopic reconstruction have recently evolved to encompass much larger breeches in the skull base following tumor removal, thus emphasizing the need for vascularized tissue flaps for reconstruction. Methods: Some authors proposed a pedicled flap of the nasal septum mucoperiosteum and mucoperichondrium, which is very vascularized and has quite a large surface. It is also long enough to easily cover even larger defects of the skull base. The elevation of a nasoseptal flap is based on a particularly advanced surgical technique and thus requires proper training before being performed in a real patient. Results: Anatomical differences between human and lamb heads were observed and explained although they do not affect the procedure of the elevation of the nasoseptal flap. Conclusions: The lamb's head has been shown to be an ideal model for the adequate training of the surgical skills required for this demanding procedure.

An animal model for endoscopic endonasal surgery and dacryocystorhinostomy training: uses and limitations of the lamb's head

Abstract: Lamb's heads are excellent models with which to teach endoscopic sinus surgery techniques. However, this study clearly demonstrated the absence of a lacrimal sac in all such models dissected. Thus, this animal model is inappropriate for endoscopic dacryocystorhinostomy training.
