The author considers successively: 1--The theoretical justifications for horizontal partial laryngectomy (anatomical considerations, indications as to the modalities of extension of supraglottic tumors, results concerning the cancer itself, functional results). 2--The indications of and contraindications for this type of surgery, with special reference to two types of cancers: median supraglottic carcinomas and antero-lateral epilarynx carcinomas. 3--Some specific problems, namely that of large supraglottic laryngectomy, of combined nodal surgery, and of preoperative radiotherapy. The limits of horizontal partial laryngectomy are specified on the basis of two criteria: its value as far as cancer is concerned (five-year survival rate), the quality of functional results.

Delivery of radiation to a deeply located tumor site by external radiation is only accomplished by traversal of normal tissues. Even with the physical advantages of high energy radiation or heavy particles, this is still unwanted radiation. Even a tumor-seeking isotope, such as radio-iodine for carcinoma of the thyroid, must still have an initial total body distribution. While interstitial sources, removable or permanent, present a personnel exposure problem, the delivery and deposition of ionizing radiation in this way has unequalled simplicity, versatility, and availability. Although the method is as old as radiotherapy itself, three dimensional computer dosimetry has given it extended applicability, and extends an invitation to innovations in achieving ideal dose distribution.

Following laryngectomy only 40 per cent of patients are able to attain esophageal speech. Several surgical and nonsurgical methods have been devised to solve this problem, but non is fully satisfactory. This paper describes two different experimental apporaches to the problem. A segment of trachea is isolated with an intact blood supply and anastomosed to the skin and esophagus, thus producing a fistula where the characteristic of the tracheo-esophageal junction can be studied. Efforts to implant a valve into this fistula have been unsuccessful but the fistula alone is patent after one year. The isolated tracheal segment provides an ideal model for study in an untracheatomized animal. In the second approach an electromagnetic sound device is being devised which can be implanted in the neck as near as possible to the previous site of the larynx. The results have been encouraging.

The microvasculature of both the human and monkey larynx is described. The recognized patterns of growth and spread of laryngeal carcinoma are discussed in relation to the microvasculature. The direction of enlargement of these tumors may be influenced by the lines of least resistance created in the tissues by the microvasculature.
