title: [Critical evaluation of jet ventilation from the viewpoint of the endoscopist].
abstract: Endoscopists' clinical experiences using jet ventilation (N2O/O2 mixture) for microlaryngoscopy, endolaryngeal microsurgery and tracheobronchoscopy of adults, children and (small) infants are advantageous. Especially authors accentuate: Improved clearness of laryngeal area; overcoming intubation obstacles; extraordinary variability of sounds' arrangement. Authors observed no complications caused by this method. A "symptom of absent sharpness" (microscope) refers to dignity of epithelial alterations at vocal cords. The hygienic molestation of endoscopist by gas backflow is disadvantageous; on the other hand the same backflow essentially excludes a potentially risk of aspiration.
