PURPOSE Traumatic optic neuropathy (TON) is a dangerous complication of head trauma but the mechanism of the symptoms still remains obscure. Moreover, there is no uniformly accepted treatment protocol for this condition. Endoscopic, minimally invasive decompression of the optic nerve in its bony canal is an alternative to conservative approach. MATERIAL(More)

The round window membrane of the inner ear of 15 guinea pigs was removed under ketamine anaesthesia. Perilymph was aspirated through the round window in 8 guinea pigs. The round window membrane had regenerated spontaneously after 2 weeks. Light microscopy revealed hair cell loss localized to the apical and basal turns of the cochlea. Morphological(More)
OBJECTIVES The aim of the study was to investigate whether orally administered steroids might improve surgical field conditions during functional endoscopic sinus surgery. METHODS Total blood loss and visualization of the surgical field during the surgical procedure were compared in 2 groups of 18 patients each with severe nasal polyposis. The groups were(More)
OBJECTIVE The objective of the study was to evaluate factors predisposing to occupational dysphonia in a group of professional voice users. MATERIAL AND METHODS The study involved 374 patients treated in the Clinic of Otolaryngology and the Phoniatric Outpatient Clinic, Department of Otolaryngology, Medical University of Białystok in 1999--2001. Group I(More)
The complaint of dizziness is one of the most common reasons that older adults feel constrained to visit the doctor's office. Because of a growing number of older people in the industrial society the problem grows. Therapeutic process of elderly people with vertigo and dizziness needs more than vestibular diagnostics. In addition to sufficient anamnesis,(More)
Background. Histopathological diagnosis of intraorbital tumours is of crucial value for planning further therapy. The aim of the study was to explore clinical utility of image-guided endoscopy for biopsy of orbital tumours. Method. Trans-nasal endoscopic biopsy of intraorbital mass lesions was performed in 6 patients using a neuro-navigation system(More)
Data regarding the safety of endoscopic skull base exploration are very scarce. With this method, fragile vital structures (cranial nerves, the optic complex, brainstem, hypothalamus or cerebral ventricles) are exposed to direct illumination within a closed space. Also, high-speed drills, cauterization and ultrasonic aspiration deliver a significant load of(More)
Recent advances in surgical endoscopy have made it possible to reach nearly the whole cranial base through a transnasal approach. These 'expanded approaches' lead to the frontal sinuses, the cribriform plate and planum sphenoidale, the suprasellar space, the clivus, odontoid and atlas. By pointing the endoscope laterally, the surgeon can explore structures(More)
BACKGROUND Bony defects extending laterally or superiorly within the posterior wall of the frontal sinus are generally deemed too difficult for endoscopic repair in spite of significant progress in surgical endoscopic techniques. PATIENTS AND METHODS We describe a technique of endoscopic repair of posttraumatic cerebrospinal fluid (CSF) leak from the(More)
OBJECTIVES Larynx squamous cell carcinoma is one of the most common forms of cancer in the area of the neck. The aim of our study was to investigate the activities of N-acetyl-beta-D-hexosaminidase (HEX) in larynx cancer compared with the specimens from the healthy space of the tumor that served as controls. DESIGN AND METHODS Larynx cancer (n=15) and(More)
