Special endoscopy standard procedures have developed 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.
Another aspect for endoscopic interventions is the rapid increase in tumorous changes in the head and neck area, particularly in the mouth, throat and larynx. The focus here is therefore on prevention and early recognition, which can be carried out endoscopically in a procedure that is non-invasive for the patient.

A condition for any successful intervention in the area of the larynx – diagnostic or therapeutic – is an ergonomically designed instrument set that has been tailored to the application. The different localizations of lesions in the pharynx or larynx and the potential difficulties of access mean 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 the cold surgical treatment of benign changes.

The laryngoscopes by Remacle have enabled Richard Wolf to develop an individual set with four surgical laryngoscops and the appropriate microsurgical instrument set which can be used for laser-assisted and cold surgical treatment.

Functional endoscopic sinus surgery (FESS - Functional Endoscopic Sinus Surgery), is a widespread operating procedure for treating paranasal sinuses and today ranks among the most advanced medical procedures. The intervention has a low risk and permits faster postoperative convalescence compared with open operations on the paranasal sinuses.
