Principles and opportunities in surgical treatment of auditory impairment

Abstract
The introduction deals with the survey of surgical opportunities in treatment of hearing imparied. According to the authors this possibility exists only with the damage of the transmission apparatus consisting of the tympanic membrane and three ear ossicles: maleus, incus and stapes. Since structures of the middle ear have been relatively small, only the development of the surgical microscope enabled an important progress in reconstructive surgery of the middle ear. Surgical treatment is indicated with the following diseases of the middle ear:
1. chronic inflammation of the middle ear
2. otosclerosis
3. chronic catharrh of the Eustachean tube
4. otitis seroza
5. inborn malformances in the development of the middle ear
6. damages on the transmition system of the middle ear caused by head injuries
The principle of surgical intervention in all listed diseases is the same: establishing the best possible transfer mechanism of auditive signals to the perceptive cells in the inner ear. In that purpose, interventions are being made at the pathologically changed section of the transmition system. Pathological aperture of the tympanic membrane is being closed by the patch of muscle fascia or perichondrium. Ear ossicles are being replaced by homoiotransplantants or plastic prothesis. We try to mobilise fixed stremen in otosclerosis. All scar tissue in the middle ear is being removed. Special tube placed through the tympanic membrane is being used for drainage of the liquid content in the middle ear. All reconstructive procedures of the middle ear demand previous elimination of all causes of illness in the temporal bone and rhynopharing. It is important to act before the changes become irreparable and before the inner structures are damaged.
