Abstract

Objective: To investigate the vestibular functions of the implanted and non-implanted sides of unilateral cochlear implant (CI) users with vertigo and dizziness. Material and Methods: In this retrospective study, the vHIT, VEMPs, and caloric test results of 12 unilateral CI users (28.0 ± 19.4) with normal inner ear structures who applied to our clinic due to vertigo and dizziness complaints between January 2018 and September 2021 test were analyzed. Results: In this study, the most common vestibular symptom (n=7, 58%) in unilateral CI users was determined as positional vertigo. High-frequency VOR gains on the implant side were within normal limits in 67% (n=8) of individuals, while it was below normal limits in 33% (n=4). On the implant side, 73% of individuals had abnormal saccular functions, while on the non-implant side, 27 % of them had abnormal saccular functions (p > 0.05). On the non-implanted side, 64% of individuals had abnormal utricular functions; on the implanted side, 100% of individuals experienced vestibular loss in utricular functions (p > 0.05). The caloric test revealed that 5 of 7 people (71%) showed unilateral caloric weakness on the cochlear implant side. Conclusion: Regular vestibular examination in the post-implantation period is suggested in unilateral CI users with vertigo and dizziness. It is really critical to use the complete vestibular test battery to follow-up the vestibular functions of CI users. It should also be kept in mind that CI users are at risk for BPPV in the future.

Özet

Amaç: Çalışmamızda, baş dönmesi ve denge bozukluğu şikayeti olan tek taraflı koklear implant kullanıcılarının implantlı ve implanstız taraflarındaki vestibüler fonksiyonlarının retrospektif olarak incelenmesi amaçlanmaktadır. Gereç ve Yöntemler: Bu çalışma, retrospektif tanımlayıcı bir araştırmadır. Çalışmamızda, Ocak 2018 - Eylül 2021 tarihleri arasında baş dönmesi ve dengesizlik şikayeti ile kliniğimize başvuran, iç kulak yapıları normal olan 12 tek taraflı koklear implant kullanıcısının (28,0 ± 19,4) Video Head Impulse Test (vHIT), Vestibular Evoked Myogenic Potentials (VEMP) ve kalorik test sonuçları geriye dönük olarak incelenmiştir. Bulgular: Bu çalışmada, tek taraflı koklear implant kullanıcılarında en yaygın görülen vestibüler semptom (n=7, %58), pozisyonel vertigo olarak belirlenmiştir. Bireylerin % 67'sinde (n=8) implant tarafındaki yüksek frekans VOR kazançları normal sınırlarda elde edilirken, % 33'ünde (n=4) normal sınırların altında elde edilmiştir. Bireylerin implant taraflarındaki sakküler fonksiyonlarının %73'ü anormal bulunurken, implant olmayan taraflarında %27'si anormal bulunmuştur (p 0.05). Kalorik testin yapıldığı 7 bireyden 5'inde (%71) ise koklear implant tarafında tek taraflı kalorik zayıflık olduğu belirlenmiştir. Sonuç: Baş dönmesi ve denge bozukluğu şikayeti olan tek taraflı koklear implant kullanıcılarında, implantasyon sonrası düzenli vestibüler değerlendirme yapılması önerilmektedir. Koklear implant kullanıcılarının vestibüler fonksiyonlarının değerlendirilmesinde vestibüler test bataryasının bir bütün olarak kullanılması oldukça önemlidir. Ayrıca, koklear implant kullanıcılarının ilerleyen dönemlerde BPPV açısından risk altında oldukları da unutulmamalıdır.
