[Intratympanic corticosteroid perfusion in the therapy of Meniere's disease].

Introduction: Over the last two decades the intratympanic perfusion of corticosteroids has been used as a minimally invasive surgical therapy of Meniere's disease. According to experimental studies the antiinflammatory, immunoprotective, antioxidant and neuroprotective role of the locally perfused corticosteroids was noticed in the inner ear structures. The recovery of action potentials in the cells of the Corti organ was confirmed as well as a decreased expression of aquaporine-1, a glycoprotein responsible for labyrinth hydrops and N and K ions derangement.

[The impact of hearing loss on the quality of life in adults].

Introduction: The hearing apparatus is one of the most important factors related to the development of oral communication. Thus, hearing disorders and deafness lead to severe handicap. Hearing impairment in adults cause verbal communication disorders that influence psychical, emotional and social functioning.

[Voice analysis before and after vocal tiredness].

Background/aim: A school teacher's occupation is one of the most vocal demanding professions. Vocal tiredness affects acoustic characteristics of voice, leads to the change in acoustic quality during vocal production. The aim of this study was to examine the influence of vocal tiredness on voice acoustic characteristics of school teachers.

[Otoacoustic emissions in hearing screening in children].

Background/aim: Prevention of the consequences of hearing loss can be accomplished by early hearing screening of the cochlear function in newborus, but also with continuous hearing screening in the early childhood. The aim of this study was to investigate the reliability and feasibility of otoacoustic emissions (OAE) in hearing screening in children, evaluate the frequency and type of hearing loss and determine etiological factors of these losses.

Methods: In the study, 133 children, aged 2 to 7.
