RESEARCH INTERESTS
Development of novel diagnostic methods, techniques of organ-sparing and reconstructive surgery, combination therapy, rehabilitation of patients with head and neck cancers, assessment of the mechanisms of carcinogenesis and tumor progression. Evaluation of the role of the immune system and oncogenic viruses in the development of tumors.
In order to improve the efficiency of treatment and functional results in patients with maxillofacial and laryngeal cancer, Dr. Choynzonov has developed and implemented into clinical practice surgeries with simultaneous replacement of postoperative defects with endoprostheses made of porous titanium nickelide and microsurgical autotransplantation of tissues.
Dr. Choynzonov has developed new approaches to the treatment of cancer of the thyroid, parotid glands, nasal cavity and paranasal sinuses. These approaches are based on organ-sparing surgery combined with intraoperative electronic and neutron external beam radiotherapy. He developed new approaches to voice restoration in patients with cancer of the larynx, oral cavity, and oropharynx, paresis and paralysis of the larynx using the method of biological feedback on the basis of mathematical modeling. He succeeded in the investigation of the mechanisms underlying tumor cell resistance to free radical damage and identified clinical and epidemiological characteristics of primary multiple tumors of the head and neck.
