Surround the patient with love and a reasonable consolation, but leave him ignorant about the things he has to overcome, and, especially, the things that threaten him.
Hippocrates
The upper respiratory tract and ear Neoplasms are relatively common and constitute 6-8% of all neoplasms in humans. The features of clinical progression, diagnostics, efficiency of treatment, and the disease prognosis depend on the location and diffusion of a neoplasm. In accordance with the International Classification of Diseases, which is based on histological differences and fe-tures of clinical presentations, neoplasms of the upper respiratory tract and ears are classified into benign and malignant tumors. In addition to this, some authors single out tumor-like lesions.
Clinical manifestations reveal the uresfeat of a neoplasm growth, its tendency to metastasize, and invade the surrounding tissues; however, a definitive decision on the character of a neoplasm is taken with regard to results of histological examination. Tumors may originate from epithelial, connecting, muscular, and nervous tissue. In ENT organs, the larynx is the most common location of tumors; the area of the nose and paranasal sinuses is less common location of tumors followed by the pharynx, and tumors are relatively rare in the ear. The most common neoplasms of ENT organs are described below.
8.1. NOSE AND PARANASAL SINUSES NEOPLASMS
As in all other parts of the upper respiratory tract, tumor-like lesions, benign tumors, and malignant tumors can be found in the nasal cavities and paranasal sinuses. In accordance with the International Classification of Diseases, in terms of frequency of occurrence, they are preceded by neoplasms of the larynx only. The most clinically important neoplasms of the nose and paranasal sinuses are described in the next sections.
