Advantages of CO2 laser use in surgical management of otosclerosis.

Background: Otosclerosis is a progressive osteo-destructive disorder of the bony labyrinth in which the fixation of the stapes causes the hearing loss. The aim of this study was the postoperative determination of parameters of the effect of surgical intervention on hearing and the incidence of complications and, on the basis of the differences in the examined parameters of the study, the estimation of the efficacy of the two mentioned surgical techniques in the treatment of otosclerosis.

Methods: In our research 40 patients with conductive hearing loss caused by otosclerosis underwent surgery with CO2 laser.

[New possibilities in the treatment of Meniere's disease].

The results of the treatment of Meniere's disease by intratympanic instillation of gentamicin in 32 patients over a 24-months period were analyzed. The receded vestibular function was found in 96.8% patients, whereas in the remaining 3.

Brainstem auditory evoked potentials following head injury.

Brainstem auditory evoked potentials (BAEP) were examined in 40 patients with subjective disorders following closed head injury (CHI), with the established degree of recovery and performed CT-scan of the head. For all BAEP parameters the interval of normality was defined as 3 SD above and below mean value in the control group comprised of 20 healthy subjects. The upper limits of thus defined intervals of normality enabled the formation of four types of findings: type 1--normal finding that was registered in 23 (57.

[Submandibular secretion of immunoglobulins IgA and IgG in peripheral paralysis of the facial nerve].

Introduction: In all lesions of the facial nerve suprachoroidally localized, and due to disturbance of parasympathetic and sympathetic component, there comes to qualitative and quantitative disorders of the secretion of submandibular salivary gland. Glandular immunoglobulins IgA and IgG are the secretion of the specific plasma cells in the interstice of this gland. The mechanism of the secretion of immunoglobulins is not sufficiently clear, but it is certainly under the direct neurogenic control, since the disorders of the secretion emerge after the denervation of the submandibular salivary gland.
