Abstract

Objective: Recently, inner ear pathologies such as large vestibular aqueduct syndrome (LVAS) and semicircular canal dehiscence (SCDS) have been suggested as causes for conductive hearing loss. Methods: In this study, vestibular evoked myogenic potentials (VEMP) results were evaluated in patients with conductive hearing loss and the impor- tance of VEMP in the differential diagnosis of middle and inner ear pathologies were determined. Results: A total of 270 ears (94 patients bilateral, 82 patients unilateral) with mixed hearing loss were included in the study. Two hundred and twelve ears had chronic otitis media (73 were cholesteatoma) where 58 tympanic membranes were intact; 42 patients were followed with the diagnosis of otosclerosis. VEMP was positive in one patient with chronic otitis media (dry, central perforation) and 3 patients with otosclerosis (7.1%). Computerized tomographic evaluation of these patients revealed bilateral LVAS in one patient and unilateral SCDS in three patients. Conclusion: VEMP may prevent patients from unnecessary surgical interventions and may guide surgeons in deciding the appropiate surgical proce- dure in patients with conductive hearing loss.

Özet

Amaç: Son yıllarda literatürde iletim tipi işitme kayıplarının etyopatogenezinde orta kulak patolojileri dışında geniş vestibüler aquaductus sendromu ve semisirküler kanal dehisansı gibi iç kulak tipi patolojilerinin de yer aldığı belirtilmiştir. Yöntemler: Çalışmamızda iletim tipi patolojilerde hava yolu vestibüler uyarılmış myojenik potansiyeller (VEMP) bulgularını değerlendirmek ve VEMP testinin iç ve orta kulak patolojilerinde ayırıcı tanıdaki önemini belirlemek amaçlanmıştır. Çalışmaya yaş aralığı 18-60 (ortalama 38,4±16,4) olan ve mikst tip işitme kaybı tespit edilen olguların 270 kulağı (94 kulak bilateral, 82 kulak unilateral) dahil edildi. Bulgular: Kulakların 212’sinde kronik otitis media (KOM)-73’ü kolesteatomlu KOM-mevcuttu. Elli sekiz kulakta timpanik membran intakttı. Unilateral KOM’lu (kuru, santral perfore) bir olguda ve otoskleroz ön tanısı ile takip edilen 42 hastanın üçünde VEMP pozitif izlendi (%7,1). Bilgisayarlı tomografik incelemelerde bu olguların birinde bilateral geniş vestibüler aquaductus sendromu (GVAS), üçünde unilateral semisirküler kanal dehisansı (SSKD) saptandı. Sonuç: İletim tipi işitme kaybı varlığında hastalara VEMP yapılması hastayı gereksiz cerrahi müdahaleden kurtarabilir ve yapılacak cerrahi girişimi belir- lemede yardımcı olabilir.
