“…Снижение амплитуды ответа при ПИОАЭ на низкие и речевые частоты наблюдаются при наличии катара среднего уха без экссудата или при наличии густого экссудата в барабанной полости [9,14]. Также имеются данные, что при наличии экссудата в барабанной полости амплитуда ответа снижается на всех частотах [15]. Цель исследования -изучить особенности регистрации отоакустической эмиссии на частоте продукта искажения у детей первых 3-х месяцев жизни после перенесенного острого воспаления среднего уха.…”

Data on the frequency and nature of hearing impairment in newborns and children during the first months of life after acute otitis media are contradictory. Otoacoustic emission is one of the methods for assessing the hearing function in infants. The main advantages of this method are objectivity, non-invasiveness, speed and accuracy. Objectives. To evaluate the features of otoacoustic emission registration at the frequency of the product distortion in children of the first 3 months of life after an acute inflammation of the middle ear. Material and methods. Distortion-product otoacoustic emission was performed in 36 children after complete recovery from acute otitis media (main group) and in 32 children without otitis media (comparison group). The estimation of the amplitude and spectrum of the response received was performed. The analysis of the otoacoustic response at frequencies of 1 kHz, 1.5 kHz, 2 kHz, 3 kHz, 4 kHz, 5 kHz, 6 kHz, 8 kHz was carried out. Results. Otoacoustic emission was registered in 74.2% of investigations in the comparison group, in 56.0% of observations in otoscopically healthy ears in case of unilateral inflammation, in 35.1% of cases after a non-suppurative form of the disease, and only in 15.4% of cases after a purulent form of acute otitis media. Statistically significant differences were revealed in the frequency of registration of otoacoustic emission in children of the examined groups. The greatest amplitude of the signal/noise relationship was recorded at frequencies of 5 and 6 kHz, and the smallest one at the frequency of 1 kHz in all studied groups. Conclusions. A decrease in auditory function is observed in children of the first 3 months of life after past acute otitis media. This is confirmed by significantly higher rate of absence of otoacoustic emission in this group of patients. Distortion-product otoacoustic emission in children of the first 3 months of life is recommended to be carried out at frequencies of 1.5 kHz and higher.

Familial Mediterranean Fever (FMF) is a progressive disease characterized by chronic inflammation, which also has negative effects on cochlear functions and hearing levels. We investigated whether the cochlear functions and hearing levels of FMF patients were different than healthy controls and also evaluated the relationship of hearing levels with the age at diagnosis, duration without treatment, and inflammation and lipid parameters in this study. A total of 60 patients diagnosed with FMF and 48 age, gender and body mass index (BMI)-matched healthy controls were included in the study. The hemogram, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and lipid parameters of the subjects were studied and they all underwent pure tone audiometry and Transient evoked otoacoustic emission tests after an otologic examination. The hearing levels of the FMF group were significantly higher than those of the control group. The TEOAE signal/noise (S/N) ratios were similar in both groups. A positive relationship was present between the audiometric test results and the age, BMI, low-density lipoprotein and triglyceride levels and a negative relationship with the high-density lipoprotein levels. A negative relationship was present between the TEOAE S/N ratios and the age of the patients, duration without treatment, lipid parameters, inflammation markers and the creatinine level. FMF patients are exposed to chronic inflammation and this can influence their hearing levels. The age at diagnosis, duration without treatment, chronic inflammation, unfavorable lipid parameters, and obesity can affect hearing tests negatively.
