ABSTRACT
The study of the effects of autonomic nervous system (ANS) function on the course of the postoperative period after removal of the vocal cord polyps with Nd:YAG laser has shown that laryngeal operations with utilization of Nd:YAG laser accelerate normalization of structural-functional condition of the vocal cords in patients with adequate autonomic support by 25-40 days compared to those with inadequate ANS function.

The aim of the present study was luminescent-histochemical study of efferent adrenergic nervous apparatus of cross-striated somatic muscles. The adrenergic innervation of human laryngeal muscles--m. thyroarytenoideus internus (m. vocalis), m. cricoarytenoideus posterior (m. posticus)--was studied in comparison with the innervation of m. pectoralis major (material obtained at 18 early autopsies) and m. gastrocnemius of the frog Rana temporaria (17 animals). In frozen sections of muscles, treated with the glyoxilic acid solution, adrenergic varicose terminals were demonstrated that were situated directly among the cross-striated muscle fibers. The problem of neuroeffector relations in the autonomic nervous system is discussed.

Assessment of functional state of the autonomic nervous system (tonicity, reactivity, support of the cardiovascular system) was made in 34 patients aged 18-64 years admitted to the ENT Research Institute for removal of laryngeal tumors. All the patients were diagnosed to have polyps of the vocal folds. Comprehensive studies suggest the conclusion on morphofunctional changes in the vocal folds which combine with adaptation-trophic disorders in the autonomic nervous system.
