Objectives: This study aimed to investigate the effects of trigeminal nerve (TN)-related somatosensory stimulation on the psychoacoustic parameters of tinnitus. Patients and Methods: This prospective observational study was conducted at the Audiology Unit of İstanbul Medipol University Hospital between August 01, 2021 and April 01, 2022. Twenty-eight patients (21 females, 7 males; mean age: 39±0.5 years; range, 18 to 65 years) with unilateral subjective tinnitus were included. The patients underwent psychoacoustic assessments under five conditions: the standard model, the mastoid model, and trigeminal stimulation at the ophthalmic (V1; forehead), maxillary (V2; maxilla), and mandibular (V3; preauricular) branches of the TN. Pitch matching, loudness matching, minimum masking level (MML), and residual inhibition (RI) were measured in each condition. Results: Significant correlations were observed between psychoacoustic parameters across different models (p0.05). Loudness and MML values were significantly higher in the standard model compared to other models (p0.05), despite lower MML values. The tinnitus intensities and MMLs measured in the standard model were significantly higher than the other models (p0.05). Similar RI rates were measured despite the lower MML levels in the preauricular model in comparison with the standard model. Conclusion: Somatosensory stimulation via the V3 branch of the TN may influence tinnitus loudness and MML without altering pitch perception. The preauricular model may serve as an alternative to the standard model, offering similar RI outcomes at lower MMLs. This approach could be particularly advantageous in patients with conductive hearing pathologies such as chronic otitis media, otosclerosis, or aural atresia. [ABSTRACT FROM AUTHOR] |

Amaç: Bu çalışmada, trigeminal sinir (TS) ilişkili somatosensoriyel stimülasyonun psikoakustik parametreler üzerine etkisi incelendi. Hastalar ve Yöntemler: Bu prospektif gözlemsel çalışma, 01 Ağustos 2021 - 01 Nisan 2022 tarihleri arasında İstanbul Medipol Üniversitesi Hastanesi Odyoloji Biriminde yürütüldü. Çalışmaya tek taraf lı subjektif tinnitus tanılı 28 hasta (21 kadın, 7 erkek; ort. yaş: 39±0.5 yıl; dağılım, 18-65 yıl) dahil edildi. Hastalar beş farklı koşul altında psikoakustik değerlendirmelere tabi tutuldu: standart model, mastoid model ve trigeminal sinirin oftalmik (V1; alın), maksiller (V2; üst çene) ve mandibular (V3; preauriküler bölge) dallarının uyarılması. Her modelde frekans eşleştirme, gürültü şiddeti eşleştirme, minimum maskeleme düzeyi (MMD) ve rezidüel inhibisyon (RI) ölçüldü. Bulgular: Farklı modeler arasında psikoakustik parametreler arasında anlamlı korelasyonlar gözlemlendi (p0.05). Tinnitus şiddeti ve MMD'ler standart modelde diğer modellere kıyasla anlamlı derecede daha yüksekti (p |
