CONTACT ENDOSCOPY CAPACITY IN DIAGNOSTICS OF OROPHARYNGEAL AND ORAL CAVITY TUMORS

Abstract

Malignant neoplasms of the head and neck are the fifth most common in the world, with a third of them detected in the oropharynx and oral cavity. The search for additional minimally invasive and effective methods of early diagnosis remains important. According to the literature, the parameters of the diagnostic value of contact endoscopy in the differential diagnosis of benign and malignant neoplasms of the oral cavity and oropharynx can reach 85-90%. However, the vast majority of works were devoted to the study of contact endoscopy with staining, in which a unified classification was not used, and difficulties in interpreting the results of the study were also noted. Promising is the use of contact endoscopy to visualize the structure of the vascular bed of the mucous membrane. In the oral cavity and oropharynx, this approach was fully applied only in one study and showed a higher diagnostic value, reaching 97%, than in studies evaluating exclusively the cellular architectonics of the neoplasm.
