OBJECTIVES to compare morphological and clinical features of antrochoanal polyps and chronic inflammation-associated polyps of the maxillary sinus. STUDY DESIGN histological and scanning electron microscopic examination of ten antrochoanal polyps and ten chronic inflammation-associated polyps of the maxillary sinus; comparison of clinical data in both(More)
BACKGROUND Osteomas are relatively common, benign, slow-growing, often asymptomatic neoplasms of the paranasal sinuses occurring mainly in the frontal and ethmoid sinuses. Surgical removal is done if they extend beyond the boundaries of the sinus, continue to enlarge, are localized in the region adjacent to the nasofrontal duct, or if signs of chronic(More)
PURPOSE Chronic rhinosinusitis (CRS) is one of the most common diseases in the modern society. In recent years endoscopic sinus surgery (ESS) has become the treatment of choice for patients with CRS refractory to medical therapy. ESS proved to be successful in most, but not all patients with CRS. Currently there is no direct method available to distinguish(More)
BACKGROUND The vasculature of the nasal mucosa in the human fetus so far has not been investigated morphologically by modern techniques. METHODS Nasal blood vessels were studied in 18-21-week-old human fetuses by corrosion casting and scanning electron microscopy. RESULTS The general vascular architecture was similar to that described for adult humans,(More)
Artificial neural networks are informatic systems that have unique computational capabilities. The principle of their functioning is based on the rules of data processing in the brain. This article discusses the most important features of the artificial neural networks with reference to their applications in otolaryngology. The cited studies concern the(More)
We report a case of a 73-year-old female with a tumour of the tongue, operated with two relapses. A single metastasis to the lymph node was present. Currently, the patient is alive without evidence of disease. The histological diagnosis of cribriform adenocarcinoma of the tongue was rendered. The differential diagnosis of adenocarcinomas of the tongue is(More)
The primary objective of surgical treatment of chronic otitis media is to remove the pathological changes and restore the biology of the middle ear. Subsequently, ossicular chain reconstruction is performed in order to restore hearing. The aim of the study was to evaluate the efficacy of mathematical models (artificial neural networks) in postoperative(More)
OBJECTIVE The main goal of the paper was to evaluate the results of surgical treatment of patients with laryngeal carcinoma, among whom cervical lymph node metastases were observed. The results of treatment were assessed after prior analysis of the following factors localization of laryngeal carcinoma, local and regional advancement, number of lymph nodes(More)
The examination of frequency of micronuclei was carried out on two groups of patients with tumors of upper respiratory tract: cancer of larynx (36 individuals) and polyps of larynx (13 persons). Groups of habitants from Katowice, Czestochowa and Nowy Sacz (cities with the different level of air pollution) and separately group of smokers, were considered as(More)
BACKGROUND The principal objective of ossiculoplasty is to reconstruct the sound-conducting system in the ear to the best possible degree after the elimination of pathological lesions from the middle ear. The ossicular chain is reconstructed with the use of the patient's own properly modelled ossicles and synthetic prostheses. The objective of the study was(More)
