[Clinical and endoscopic aspects of surgically treated laryngeal cancer].

This paper presents the results of fibroendoscopic examinations of 74 patients with laryngeal cancer of II-IV degree. Tumor dissemination was T2NO in 25 patients, T3NO in 36 patients, and T4NO in 13 patients. All the patients underwent modified resection patterns: 53 patients--horizontal resection (4 modifications) and 21 patients--frontolateral resection in the lower modification. Altogether 170 fibroendoscopic examinations were performed. Fibrolaryngoscopy helps to examine all laryngeal structures, evaluate and differentiate changes after various modifications of organ-preserving operations in the case of laryngeal cancer, and to detect at an early postoperative stage further tumor growth. Correct assessment of postoperative changes in the larynx prior to fibrolaryngoscopy can be carried out on the basis of reliable information about the operation, amount of tissue removed, and organ reconstruction.

[Surgical aspects of recovery of vocal function after radical removal of the larynx in cancer].

The paper is devoted to surgical procedures aimed at voice reestablishment in patients without larynx removed for cancer. Original surgical techniques practiced by the authors are proposed: tracheoesophageal shunt with creation of the defense valve from the esophageal mucosa, esophagus and lower lip mucomuscular graft, bypass repair. The procedures were used in 79 patients with removed cancer-affected larynx. Vocal function recovery occurred in 90%, the defense function restored in 80% of the patients treated.

[Laryngeal resection in cancer using endoprosthesis].

The authors have developed an original prosthetic appliance made of silicone rubber which makes it possible to conduct resections in advanced laryngeal tumors. Endoprosthetic resections have been performed in 21 patients. Frontal and lateral endoprosthetic laryngeal resections carried out in 15 patients enabled decanulation in 12 (80%) and voice recovery in 14 (93.3%) patients. 6 patients have undergone horizontal endoprosthetic resection after which 5 of them recovered respiratory and defense function. Vocal function returned to normal condition in all of them.
