          Abstract

          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.

            Cadaveric Temporal Bone Dissection: Is It Obsolete Today?

            Introduction Traditionally, surgical training in otology, is imparted by dissecting harvested human cadaveric temporal bones. However, maintenance of a cadaveric temporal bone laboratory is expensive and carries risk of exposure to infection. In recent times, other modalities of training are gaining ground and are likely to eventually replace cadaveric temporal bone dissection altogether. Objectives Other alternative methods of training are emerging. New technology like simulation and virtual reality as high-fidelity, safer alternatives, are making rapid strides as teaching tools. Other options are the use of animal temporal bones as teaching tools. The advantages of these are compared. Data Synthesis None of these modalities can replicate the innumerable anatomical variations which are a characteristic feature of the human temporal bone. A novice surgeon not only needs exposure to surgical anatomy and it's variations but also needs to develop hand-eye coordination skills to gain expertise. Conclusion Deliberate practice on human cadaveric temporal bones only, will confer both mastery in anatomy and surgical technique. The human cadaveric temporal bone is ideal simulator for training in otology.

              Preparation of a temporal bone exhibit.

              Temporal bone dissection forms an important aspect in the training of an otolaryngologist. The more dissection one does the more confident one is in the operating room. The aim of this paper is to advise in the preparation of temporal bones for the purpose of display, exhibition or competition. The practical aspects of dissection are deliberately avoided concentrating on the selection of bones pre- and post-dissection, preparation of the bones, fixing and display of vessels and nerves and also mounting and lighting for exhibition purposes. The temporal bone laboratory should be well equipped with a microscope, a power drill with a range of cutting and polishing burrs, a range of fine instruments, a suction machine with different sizes of suction tips, water source, a place to store the bones etc., thus creating an ideal environment for temporal bone dissection.
