The role of pre-radiation topometric preparation of patients with malignant tumors of the oral cavity and oropharyngs in the prevention of radiation injuries

Precision clinical topometry is the most important attribute of pre-radiation preparation of patients. Its underestimation and implementation of radiation therapy on the basis of schematic planning, according to various authors, can cause the development of radiation injuries from 6-10% to 61.2% in patients with malignant tumors of the oral cavity and oropharyngeal region. This is due to the sharp gradient of the absorbed radiation dose arising from the inhomogeneity of the irradiated volume. The adequacy of the performed topometric studies is in direct proportion to the radiation damage.
