Special endoscopy standard procedures have advanced over the past two decades for diagnostics and therapy in diseases of the ear, nose, paranasal sinuses, buccal cavity, pharynx and larynx and in voice disorders. In addition, the rapid increase in tumorous changes to the head and neck area has amplified focus in prevention and early recognition.
A factor for any successful intervention in ENT—diagnostic or therapeutic—is an ergonomically designed instrument set tailored to the application. The different localizations of lesions in the pharynx or larynx and the potential difficulties of access means that laryngologists used to require a wide range of different laryngoscopes that would be available for each intervention to take account of these difficulties. The same principle applies for instruments used in minimally invasive interventions, which were originally developed for cold surgical treatments.
