Subglottic space is very difficult to observe under usual oral inspection or endoscopic method. Transconioscopy is performed by inserting endoscope through anterior neck into crico-thyroid space, it is the best way to inspect subglottic space and its surroundings. So it can be called retrograde laryngoscopy or subglottoscopy. Transconioscope which diameter is about 4mm has been already used in Sweden and Japan, but it needs skin incision and causes ill effects as bleeding or subcutaneous emphysema owing to its thick diameter.<BR>New type of our transconioscope designed under selfoc lens system is very slender, its diameter is 1.7mm, so it can be stabbed into the subglottic space through guide of outer casing and trocar of 2.0mm diameter under light local anaesthesia withont skin incision, it gives no pain and almost all view is observed by moving this needle scope in different direction, color photography, and simple biopsy are also available with high powered light source. Thers is no contraindication on this method. More than 100 cases of various kinds of laryngeal diseases including inflammation, nerve paralysis, tumors, hoarseness, hemoptysis, ozaena, tbc. etc were inspected. And others endoscopy from tracheostoma, maxilloscopy, olfactoscopy, tympanoscopy were also experienced. I found it of much value on diagnosis and therapy in respective laryngeal and other diseases.
