“…According to the results of ipsilateral and contralateral acoustic reflex of both ears, information about lesion locations and their effects on hearing can be obtained. [26] In this study, no statistically significant difference was observed between keratoconus and healthy subjects in acoustic ref lex evaluation. This shows that no pathological changes have been observed in the anatomical structures of the acoustic reflex pathway.…”

Bu çalışmada keratokonuslu hastaların işitme durumu değerlendirildi. Hastalar ve Yöntemler: Kasım 2018-Nisan 2019 tarihleri arasında gerçekleştirilen bu olgu-kontrol çalışmasına 23'ü (12 erkek, 11 kadın; ort. yaş 31.6±7.8 yıl; dağılım, 20-46 yıl) keratokonus tanısı almışken 33'ünde (13 erkek, 20 kadın; ort yaş 30.8±4.4 yıl; dağılım, 18-49 yıl) hiçbir göz hastalığı olmayan (kontrol grubu) 56 denek (25 erkek, 31 kadın; ort. yaş 31.2±7.5 yıl; dağılım, 18-49 yıl) dahil edildi. Tüm hastalarda saf ses odyometrisi, immitansmetrik ölçümler ve işitsel beyin sapı yanıtı testleri uygulandı. Grupların odyolojik test sonuçları karşılaştırıldı. Bulgular: Grupların yaş ve cinsiyet dağılımı arasında istatistiksel olarak anlamlı farklılık yoktu (sırasıyla, p=0.336 ve p=0.125). Kontrol grubunda 2000 Hz'deki akustik refleks değeri keratokonus grubundan anlamlı şekilde yüksekti (p=0.030; p<0.05). Grupların diğer akustik refleks ölçümlerinde anlamlı farklılık yoktu (tüm p değerleri >0.05). İşitsel beyin sapı yanıtı testi ölçümlerinde I-III, III-V ve I-V dalga gecikmeleri arasında istatistiksel olarak anlamlı farklılık yoktu (tüm p değerleri >0.05). Sonuç: Bu çalışmanın sonuçlarına göre, keratokonuslu hastalarda işitme kaybı beklenmemektedir. Dolayısıyla, bu hastalarda rutin işitme muayenesine gerek olmadığına inanıyoruz. Daha büyük örneklem boyutları olan, uzun süreli takip çalışmaları gereklidir.

“…Moreover, MEMR growth has been observed to decrease as a function of age (Thompson et al, 1980 ). In contrast, Unsal et al ( 2016 ) found no differences in either the MEMR thresholds (obtained by the standard clinical probe tone approach) using 4 kHz tonal elicitors, or the MEMR decay, between older and younger adults. The correlation between MEMR thresholds/growth functions and aging in the above studies could be at least partially explained by age-related declines in central auditory neural pathways (Ouda et al, 2015 ), which need to be accounted for in the investigation of age-related CS using MEMR measures.…”

Animal studies have shown that noise exposure and aging cause a reduction in the number of synapses between low and medium spontaneous rate auditory nerve fibers and inner hair cells before outer hair cell deterioration. This noise-induced and age-related cochlear synaptopathy (CS) is hypothesized to compromise speech recognition at moderate-to-high suprathreshold levels in humans. This paper evaluates the evidence on the relative and combined effects of noise exposure and aging on CS, in both animals and humans, using histopathological and proxy measures. In animal studies, noise exposure seems to result in a higher proportion of CS (up to 70% synapse loss) compared to aging (up to 48% synapse loss). Following noise exposure, older animals, depending on their species, seem to either exhibit significant or little further synapse loss compared to their younger counterparts. In humans, temporal bone studies suggest a possible age- and noise-related auditory nerve fiber loss. Based on the animal data obtained from different species, we predict that noise exposure may accelerate age-related CS to at least some extent in humans. In animals, noise-induced and age-related CS in separation have been consistently associated with a decreased amplitude of wave 1 of the auditory brainstem response, reduced middle ear muscle reflex strength, and degraded temporal processing as demonstrated by lower amplitudes of the envelope following response. In humans, the individual effects of noise exposure and aging do not seem to translate clearly into deficits in electrophysiological, middle ear muscle reflex, and behavioral measures of CS. Moreover, the evidence on the combined effects of noise exposure and aging on peripheral neural deafferentation in humans using electrophysiological and behavioral measures is even more sparse and inconclusive. Further research is necessary to establish the individual and combined effects of CS in humans using temporal bone, objective, and behavioral measures.

“…A study was done to assess the ART and RDT in the geriatric group by Ünsal et al who concluded that although some changes were observed due to age, middle ear and stapedius work normally in geriatric category as no significant difference was found between geriatric and non-geriatric categories in ipsilateral and contralateral AR parameters and RDT [ 13 ]. Virtaniemi et al concluded that decreased ARAs and prolonged ARLs in subjects with insulin-dependent diabetes mellitus (IDDM) were more probably attributed to the rigid middle ear structure than brainstem alterations [ 14 ].…”

Purpose Type 2 diabetes mellitus (T2DM) may induce micro-vascular and macro-vascular changes that can lead to neuropathic changes which may affect the auditory pathway resulting in hearing loss. The study aims to evaluate the outcome of ipsilateral and contralateral acoustic reflex (AR) parameters and reflex decay tests (RDT) in patients with T2DM, and the relationship between average AR parameters, and duration and control of T2DM. Methods An analytical cross-sectional study was conducted in a tertiary care setup in 126 subjects which included 42 subjects with T2DM between 30 and 60 years of age, age-matched with 84 non-diabetic subjects. The subjects were evaluated for pure tone average (PTA), speech identification score (SIS), AR parameters [acoustic reflex threshold (ART), acoustic reflex amplitude (ARA), acoustic reflex latency (ARL)] and RDT. Results The subjects with T2DM showed increased PTA in both ears when compared to the subjects with no disease. No significant difference was found in the SIS between both groups. There was no significant difference in the ART and ARL between the two groups. There was a significant difference in the ipsilateral and contralateral ARA at 500 Hz, 1000 Hz and broadband noise (BBN) when compared between the diabetic and non-diabetic groups. No significant difference was found between average AR parameters and duration and control of T2DM. Conclusion T2DM increases hearing thresholds and reduces ipsilateral and contralateral AR at lower frequencies and BBN. Duration and control of T2DM do not affect the AR parameters.
