Treatment of patients with tumors of the maxillofacial region is a complex multi-step process. The type and volume of treatment were determined by the prevalence of cancer process. The plan of complex treatment of this group of patients was made individually but depending on the morphological variant, clinical and anatomic characteristics, dental status, carcinogenic factors and stage of disease. For dynamic observation of the stages of treatment it is advisable to use biomarkers, through which it is possible to monitor the resulting effect.

Modern data of the etiology of squamous cell carcinoma (SCC) of the mucous membrane of the oral cavity (MMOC) show an increasing prevalence of the disease, a high mortality rate despite the development of modern methods of diagnosis and treatment. SCC is a group of polyetiological diseases. Among the most often etiological factors the use of tobacco products is found as one of the main cause of the disease with the division into active or passive methods of their use, prevalence and potential pathogenicity. Also the risk of the development of SCC MMOC depends on the consumption of alcoholic product as the long-acting traumatic factor. There were analyzed and considered the most common precancerous diseases of the mucous membrane of the mouth, their private and common significance in the structure of precancerous diseases. There was revealed the high correlation between periodontal disease and the development of SCC MMOC, which corresponded to the general assumption about the risk of oncology development against the background of chronic infection in the oral cavity. There were identified new data of the relation between the carriers of some types of the viruses of human papillomavirus and the development of SCC MMOC. Particular understanding of the causal relation of presented on-copathology allowed judging the lack of preventive measures, the necessity of required qualification of specialists of dental and related profile.

Treatment of patients with malignant tumor of oropharyngeal region is a difficult problem due to the last detection of diseases and complex anatomic structure, despite the emergence new and improvement methods of the treatment of cancer of oropharyngeal region. Complex rehabilitation of this patients presents great difficulties due to the disturbance of breath, swallowing, speech, and the lack of a single methodological approach to treatment. It is needs to improve the effectiveness of prosthetic care for patients with malignant tumor of oropharyngeal region.

Question on comprehensive dental care to patients with squamous cell carcinoma (SCC) of the mucous membrane of the oral cavity (MMOC) showed the importance of a team approach of physicians of allied specializations, careful planning and consistent implementation of rehabilitation treatment stages of cancer. The implementation of preventive measures showed a reduced severity or absence of complications conducted by the primary treatment. The data about the important role of preoperative sanitation of the oral cavity are presented. There are described the pathogenesis of the most common complications and identified effective methods of prevention and treatment, as well as the mechanisms of action of different prevention methods. Characteristic signs of “radiation caries”, oral mucositis, dysgeusia, xerostomia, lockjaw chewing muscles, osteoradionecrosis, dysphagia and neurotoxic effects of chemotherapy drugs are marked. It is necessary to emphasize the considerable effect of such complications on quality of life of patients after treatment. This again proves a need for an integrated approach and participation in the work of the specialists of a number of related disciplines.
