Tinnitus
Özet
Tinnitus, harici bir ses uyaranı olmaksızın bir veya iki kulakta ses algılanması olarak tanımlanır ve dünya genelinde nüfusun %10-15'ini etkileyen yaygın bir durumdur. Objektif (başkaları tarafından duyulabilen) ve subjektif (sadece hasta tarafından duyulabilen) olarak ikiye ayrılan bu rahatsızlık, sıklıkla yaşa bağlı işitme kaybı, mesleki gürültü maruziyeti ve vasküler patolojilerle ilişkilidir. Tanı sürecinde detaylı anamnez, kulak burun boğaz muayenesi ve saf ses odyometrisi dahil kapsamlı odyolojik tetkikler kritik rol oynar. Tek taraflı veya pulsatil vakalarda BT ve MR gibi görüntüleme yöntemlerine başvurulması gerekir. Günümüzde tinnitus tedavisinde Amerikan Gıda ve İlaç Dairesi (FDA) tarafından onaylanmış spesifik bir ilaç bulunmamaktadır. Tedavi yaklaşımları daha çok konservatif yöntemleri, işitme cihazları ve geniş bant gürültü üreten cihazlarla yapılan ses terapilerini, Tinnitus Yeniden Eğitim Terapisini (TRT) ve bilişsel davranışçı psikoterapiyi kapsamaktadır. Rutin medikal tedavilerin, antidepresanların veya Ginkgo Biloba gibi diyet destek ürünlerinin semptom şiddetini azaltmadaki etkinliği klinik olarak kanıtlanmamıştır. İleri derece işitme kaybı olan seçilmiş kronik vakalarda ise koklear implant uygulamaları tinnitus algısını önemli ölçüde azaltabilmektedir.
Tinnitus is defined as the perception of sound in one or both ears without an external auditory stimulus, affecting approximately 10-15% of the global population. Classified into objective (audible by others) and subjective (audible only to the patient), it is frequently associated with age-related hearing loss, occupational noise exposure, and vascular pathologies. The diagnostic process relies heavily on a detailed medical history, otoscopic examination, and comprehensive audiological evaluations, including pure-tone audiometry. In cases of unilateral or pulsatile tinnitus, advanced imaging techniques such as CT and MRI are indicated to rule out focal lesions or vascular malformations. Currently, there is no specific medication approved by the Food and Drug Administration (FDA) for treating tinnitus. Management strategies primarily focus on conservative approaches, sound therapies utilizing hearing aids or broadband noise generators, Tinnitus Retraining Therapy (TRT), and cognitive behavioral therapy. Routine medical treatments, including antidepressants, anticonvulsants, and dietary supplements like Ginkgo Biloba, have not demonstrated proven clinical efficacy in reducing symptom severity. However, in selected chronic cases presenting with severe-to-profound hearing loss, cochlear implantation has been shown to successfully alleviate tinnitus perception.
