The purpose of this article is a retrospective analysis of cases with suspected laryngeal trauma. The clinical importance, possibilities and limits of computertomographic diagnostics in laryngeal trauma are discussed. ⋯ High resolution spiral computed tomography is the method of choice to detect or exclude laryngeal fractures after an isolated neck trauma. Special parameters are necessary for detection of subtle pathological findings. In the estimation of mucosal or vocal cord changes the CT is inferior to endoscopy.

Surgical skill requires training at close-to-reality scenarios. Conventional procedures (practical exercises, anatomical or animal cadavers) are increasingly in conflict with objective parameters (costs of OR, quality management, cadavers availability and cost). Surgical procedures can be covered by using Virtual Surgical Reality (VSR). ⋯ VSR systems have the potential to revolutionize surgical training. All surgical experienced probands evaluated the VSR-scenario as near-to-reality. "Suspension of Disbelief" is the major condition for effective virtual reality training systems.

Comparative Study[Is the observation of patients with sleep-apnea-syndrome after surgery of the upper airway in an intensive care unit generally necessary?].
Although it is known that after surgery of the nose and/or the paranasal sinuses serious complications can arise for patients suffering from Sleep-Apnea-Syndrome (SAS), there exists no general recommendation for postoperative care of these patients. This retrospective analysis is dealing with the question whether it is generally necessary to observe SAS-patients after nasal surgery including intubation in an Intensive Care Unit (ICU). ⋯ Patients suffering from a mild to moderate SAS do not need a general postoperative surveillance in an ICU if the chosen form of anesthesia is considered concerning this sickness.

Comparative Study[Injuries of the head and neck in suicidal intention].
Injuries of the head and neck with suicidal intention might create serious situations that require rapid and interdisciplinary treatment. ⋯ The presented study emphasizes the need of immediate surgical and intensive care treatment of patients with head and neck injuries due to suicide attempts as well as an adequate psychiatric supervision during as well as after the surgical treatment.

Comparative Study[Evaluation of the insertion-trauma of the Nucleus Contour Advance electrode-array in a human temporal bone model].
The development of intracochlear electrode arrays is aiming at a placement close to the modiolus with an insertion as atraumatic as possible. A new perimodiolar electrode model the Nucleus Contour Advance was to be evaluated regarding the possible intracochlear trauma. ⋯ The Nucleus Contour Advance electrode array showed minimal trauma in human temporal bones by using a standard insertion technique. By using the freehand AOS-technique a severe cochlear trauma is possible. Therefore further development in electrode design and the use of an insertion-tool is recommended.
