Medium ear findings in parkinson's disease

The eustachian tube has very important functions for the middle ear. The middle ear is balanced with atmospheric pressure to ensure that the pressures inside and outside the tympanic membrane are equalized. The best sound transmission occurs when the eardrum is at its highest amplitude and has equal pressure on both sides. It also provides nasopharyngeal drainage of fluid produced in the middle ear and protects the middle ear against reverse flow and pressure. Parkinson's disease is a slow progressive neurodegenerative brain disease (with loss of brain cells). Normally, there are brain cells that produce dopamine in certain regions of the human brain. These cells are concentrated in a specific area of the brain called the nigra. Dopamine is a chemical substance that transmits messages between nigra and other brain regions that control body movements. Dopamine allows people to make fluent and harmonious movements. When 60% to 80% of the dopamine producing cells are lost, sufficient amount of dopamine can not be produced and the motor signature of the Parkinson's disease appears. Multifrequency tympanometry is an advantageous test method that can analyze middle ear resistance and permeability in a wide frequency range by providing analysis of tympanograms obtained with probe tones ranging from 226 Hz to 2000 Hz. Middle ear admittance and its components. One of the important parameters provided by multifrequency tympanometry is resonance frekans. In the presence of certain pathologies, resonance frequency values are lower or higher than normal and healthy ears. In our study, it was aimed to examine the resonance frequencies of these patients with multifrequency timopenemetry, considering that the anterior tube dysfunction, which may be caused by impaired muscle coordination in patients with Parkinson's disease, may affect the middle ear. For this purpose, 15 volunteers (30 ears) between the ages of 60-88 who have normal otoscopic examination with the diagnosis of Parkinson's disease by the Department of Otorhinolaryngology, Başak University Earl-Nose-Throat Department, Ear) healthy volunteer participant. Immunometric measurements of participants who underwent otoscopic examination by an ENT specialist were performed. Resonance frequency values taken from both ears (60 ears) of all participants were taken into consideration. For the patients who had Parkinsonian measurements, the right ear resonance frequency average was 1160,00 ± 519,34 Hz, the resonance frequency average for the left ear was 1123,33 ± 559,932 Hz and the resonance frequency average for the right ear of the control group was 946,67 ± 480,501 Hz, The resonance frequency average for the ear was 933,33 ± 447,879 Hz. No significant difference was found between the resonance frequency values of the parkinsonian patients and the resonance frequency values of the control group.
