OBJECTIVE: Intratympanic (IT) dexamethasone offers a good method for avoiding systemic side effects in patients with sudden idiopathic sensorineural hearing loss (ISSHL). However, in most studies, IT was used as a salvage treatment for patients whose hearing failed to improve with the initial systemic treatment, or as an addition to conventional oral steroid protocols. Therefore, we investigated the outcomes of IT steroid administration as a primary treatment modality for ISSHL. STUDY DESIGN: Ra

The findings of this study strongly suggest that there are associations between sleep quality and some disease subtypes associated with dizziness. Therefore, it is important to consider sleep disturbance in patients with psychogenic dizziness, such as phobic postural vertigo and chronic subjective dizziness, or nonspecific dizziness.

OBJECTIVE: Saccule could be damaged in patients with idiopathic sudden sensorineural hearing loss (ISSHL) with vertigo and with high-frequency sensorineural hearing loss. Thus, the saccule might be deteriorated subclinically in ISSHL cases without vertigo. Therefore, we investigated saccular damage in ISSHL patients without vertigo through vestibular evoked myogenic potentials (VEMP). STUDY DESIGN: A prospective study. SUBJECTS AND METHODS: Fifty-two patients with ISSHL without vertigo were enro

OBJECTIVE: Patients with migraine headaches have a high prevalence of episodic vertigo, and several studies support the clinical association of migraine and vertigo. Various tests have been conducted in patients with migrainous vertigo; however, only a few studies have been reported on otolith function. The aim of the present study was to increase the understanding of migrainous vertigo pathophysiology by assessing the sacculocollic pathway in patients with migrainous vertigo using vestibular-ev

Abnormal VEMP rates in the vestibular neuritis, BPPV, and Meniere's disease groups were 36.6%, 25.8%, and 69%, respectively. The proportion of prolonged p13 latency in BPPV patients with abnormal VEMP responses was relatively high compared with the other two diseases. VEMP asymmetry in the patients with Meniere's disease was relatively high.

OBJECTIVES: Some patients with dizziness show high comorbidity with psychiatric disorders. However, the association of vestibular deficit with psychological symptoms remains controversial. Thus, we investigated psychological distress (depression and anxiety) in patients with vestibular disease and examined factors modifying the development of psychological distress in these patients, including age, sex, severity of dizziness symptoms, and type of vestibular disease. STUDY DESIGN: Prospective stu

BACKGROUND: Hearing loss can lead to a number of disabilities, subsequently reducing the quality of life. In general, hearing thresholds of adolescents are better than adults and the elderly. However, occasionally, adolescents acquire hearing loss for a number of reasons. In this study, our goal was to estimate the prevalence of hearing loss in the Korean population and to investigate the factors related to hearing thresholds in adolescents. METHODS: A cross-sectional study was conducted using d

Causes of fracture, gender distribution, manifestations of temporal bone fracture, and clinical symptoms were similar in adults and children (p > 0.05 each). Petrous fracture, ear fullness, dizziness, and tinnitus were significantly more frequent in adults than in children (p < 0.05 each).

In Brief Objectives: Clinicians sometimes treat patients with relatively long-duration geotropic direction-changing positional nystagmus (DCPN), without latency. Recently, the concept of a “light cupula” in the lateral canal that reveals persistent geotropic DCPN has been introduced. In the present study, we investigated the immediate and short-term therapeutic findings in long-duration DCPN. Design: The authors prospectively compared the therapeutic efficacy of a canalith-repositioning procedur

Of 13 patients with ISSNHL and BPPV, 11 showed profound hearing loss. The lateral canal was involved in 11 patients, including 3 who had multi-canal involvement. Ten patients underwent a single repositioning maneuver. Those patients did not display a significant difference in hearing recovery compared with those patients having ISSNHL only.

Our results support the possibility that the mechanism between persistent and transient geotropic DCPN may be different. However, more studies are needed on the pathogenesis and mechanism of the two diseases, including the occurrence of pseudo-spontaneous nystagmus in the disease entity.
