[Abscess of the parapharyngeal space].

The abscess of parapharyngeal space is very dangerous health condition graving numerous complications such as: jugular vein thrombosis, mediastinitis, arterial bleeding. This state originates most frequent during the acute pharyngitis, and especially acute tonsillitis. The aim of our study was to review the clinical sings, computed tomography scans and outcome of parapharyngeal space infection.

[Study of selected biomaterials for reconstruction of septal nasal perforation].

Introduction: The septal nasal perforation is an important problem for the laryngologists and plastic surgeons. The reasons of septal nasal perforations are injuries, neoplasm, self-mutilation, chronic rhinitis, allergy, Wegener granuloma, sarcoidosis, tuberculosis, toxic metals (arsenic, chrome), some drugs (steroids), narcotizing agents (cocaine) and complications after endoscopic and septal nasal operations. The surgical treatment, especially in the cases of large septal perforation, is often difficult because of the atrophy of nasal mucosa and lack of suitable material for reconstruction.

[Surgical treatment of patients suffering from allergic chronic sinusitis with nasal polyps].

Introduction: Chronic sinusitis with nasal polyps is very often associated with allergy. The results of surgical treatment (Functional Endoscopic Sinus Surgery--FESS) in this group of patients are different and rather poor, especially in long term observations.

The Aim: of our study was to evaluate the results of surgical treatment (FESS) in patients suffering from chronic sinusitis with nasal polyps associated with allergy.

[Strategy of the sinonasal tumors treatment].

Introduction: The sinonasal tumors belong to rare diseases. They state 0.2-0.

[An unusual parotid gland foreign body].

A foreign body in the parotid gland is extremely uncommon. It can penetrate to the parotid gland through the skin or from the oral cavity via the Stenonís duct. A case of 23-years-old man with the several pieces of glass within the superficial lobe of the right parotid gland was described.

[Otoacoustic emissions measurements in children during the chemotherapy because of the acute lymphoblastic leukemia].

Introduction: Chemotherapy is associated with an increased risk of ototoxic changes. The predictive value of conventional pure-tone audiometry on early detection of ototoxicity has been questioned. Otoacoustic emissions (OAEs) appear to be more sensitive to cochlear insult than the conventional pure-audiometry.

[Rare case of primary sinonasal tuberculosis].

Introduction: Tuberculosis, considering entry of infection, most frequent concerns the lungs. Rarely we observed extrapulmonary cases of tuberculosis within the bones, joints, urogenital organs and lymph nodes as well as within the head and neck region--larynx, middle ear, pharynx, tonsils, tongue, parotid glands and central nervous system. Sinonasal tuberculosis, either primary or secondary to pulmonary infection, is very rare, but should be considered in the differential diagnosis of sinonasal granulomas.

[Tuberculosis within the laryngologic organs].

Unlabelled: Tuberculosis, considering entry of infection, most frequent concerns the lungs. Rarely we observed extrapulmonary cases of tuberculosis within the bones, joints, urogenital organs and lymph nodes as well as within the head and neck region--larynx, nose and paranasal sinuses, middle ear, pharynx, tonsils, tongue, parotid glands and central nervous system. The diagnosis of head and neck tuberculosis is based on patient's examination as well as on the bacteriologic and histologic study of the biopsy specimen.

[Hearing evaluation in children during chemotherapy].

Chemotherapy is associated with an increased risk of ototoxic changes. The purpose of our study was to investigate the clinical usefulness of Distortion Product Otoacoustic Emissions (DPOAEs) as early indicator of chemotherapy-induced ototoxicity. Tonal audiometry, emission audiometry and DPOAEs were measured in 7 children with acute lymphoblastic leukemia (ALL).
