Recently partial laryngectomy or well planned irradiation may enable to control or cure some selected cases of tumors in locations where total laryngectomy would involve unnecessary sacrifice of laryngeal function. The possibility of carrying out such function-conserving surgery or irradiation depends especially upon the meticulous study of their size, inferior extent and invasion of neighbouring tissues.Laryngography for examining the larynx and hypopharynx with a mucosal coating of ‘Dionosil Oily’ described originally by Powers et al, has proved to be direct, simple, accurate and safe and to provide a wealth of anatomic detail and information of any lesions in these area.Our laryngographic technique is essentially the same as that of Powers. That is to instill approximately 15, to 20c c. of Dionosil Oily into the larynx and hypopharynx under the local anesthesia, then 8 spot-films are obtained in the frontal and lateral positions during quiet inspiration, phonation, the Valsalva and modified Valsalva maneuvers. Detecting the suitable technical factors, the good visualization of the neighbouring soft tissues as well as the key area can be obtained.Detailed anatomies of the normal laryngogram in 4 physiological status with some descriptions of the physiologic variations which are likely to be mistaken for the invasion of tumors were also discussed.In conclusion, it must be emphasized that the interpretation of laryngogram could not be done with accuracy unless 8 spot-films are examined as a whole and that the detection of the suitable technical factors is of vital importance for good results.
