일측성 청력 감소를 동반한 반복된 어지럼 환자의 청력도에 따른 임상양상의 차이 = Episodic Dizziness with Unilateral Hearing Loss: Clinical Characteristics According to Hearing Loss Pattern

다국어 초록 (Multilingual Abstract)

Background and Objectives Low frequency hearing loss is known to be the most common hearing loss form in Meniere’s disease (MD) and episodic dizziness with low frequency sensorineural hearing loss is considered a very crucial symptom for the diagnosis of MD. However, flat or high frequency hearing loss is also commonly encountered in the Ear, Nose and Throat clinic. The aim of this study is to investigate the differences in clinical manifestation between episodic dizzy patients with low frequency hearing loss (LFHL) group and non-low frequency hearing loss (non-LFHL) group.
Subjects and Method We reviewed medical records of 78 patients (36 of LFHL group and 42 of non-LFHL group) who had episodic dizziness with unilateral hearing loss and analyzed clinical characteristics according to hearing loss pattern.
Results The clinical features of LFHL include a predominance of female sufferers, high incidence of tinnitus and short duration of dizziness. There was no significant difference in frequency, nature of dizziness, and results of vestibular function test. Although the proportion of patients diagnosed with definite MD was higher in LFHL group at initial and final diagnosis, there were no statistically significant differences between two groups.
Conclusion Therefore, when episodic dizziness is accompanied with unilateral hearing loss, not only low frequency but flat or high frequency hearing loss could be considered as a critical sign for possible progression to Meniere’s disease and careful observation should be taken.
