The bronchofiberscope has facilitated endoscopic examinations through tracheostoma making it essentially more tolerable and safe. Because of anatomical and technical reasons it is not possible however to insert a rigid tube through a stoma to the proximal part of the trachea. In this report the authors deal with retrograde tracheo-laryngofiberscopy (RTL), namely the intubation of the above-mentioned area through the stoma for endoscopic examination, the possiblilities, limits and indications of the method and their own experience up to the present.
