The aim of our work was the application of sonographic method in the diagnosis 75 patients of larynx carcinoma. Aloka Hellige type SSD 280 LS was used on the examination in real time. The sonographic images were compared with the results obtained in the indirect and direct laryngoscopy, postoperational evaluation and histopathological picture. Sonography may prove to be a potentially useful for expanse of cancer of the larynx.
The aim of our work was the application of sonographic method of the larynx. Aloka Hellige type SSD 280 'LS was used on the examination in real time. Sonographic images of the larynx were obtained in 25 healthy human and 25 healthy children. Sonography may probe to be a potentially useful technique for the examination of the larynx.
Indications for hearing implants in profoundly deaf patients have been presented. Auditory pathway status was evaluated by application of electrical stimulation of cochlear nerve. The electrical stimulus originated from Cochlear Nerve Tester. Obtained sound sensations might be revealed on ABR pattern.

A case of the 38-years old patient with a severe streptococcal phlegmon fundi oris and secondary deficiency of gamma-globulins was reported. The patient was successfully treated by surgery, proper antibiotico-therapy and immunoregulation.
The collagenous protein level in the inflammatory status of middle ear mucosa taken during the surgery in 16 patients were analysed. The more accentuated changes were in longer duration of disease. The collagenous protein level play probably an important role in the healing processes after tympanoplasty.
Investigations were carried out to examine the ability to differentiate low-grade changes in tone frequency in 58 subjects (116 ears) with noise-induced hearing impairment. The results were compared with those obtained in an age-matched group of healthy controls with normal hearing acuity. Statistically, the slight discrimination of frequency changes was found to be significantly worse in the group with noise-induced hearing impairment.
