Postural orthostatic tachycardia syndrome (POTS) is a cerebrovascular autonomic dysfunction that is common in young women. POTS can cause dizziness due to orthostatic intolerance. In patients with orthostatic intolerance, it can be diagnosed when the heart rate increases by more than 30 beats per minute within 10 minutes of standing up through the head-up tilt test. However, even a neuro-otologist has difficulty in diagnosing POTS due to the high possibility of misdiagnosis if not paying attention. In this paper, the clinical symptoms, pathophysiology, diagnosis, and treatment of POTS are investigated. In addition, the latest knowledge of POTS is searched to help diagnose and treat POTS.

The aim of this study is to investigate the characteristics of anterior semicircular canal benign paroxysmal positional vertigo (BPPV). Materials and Methods: This is a retrospective chart review of 1,150patients who were diagnosed with BPPV at an ENT special hospital. We investigated a number of canalith repositioning procedure (CRP), canal switch and a history of recurrence or head trauma. Results: Anterior semicircular canal BPPV was observed in 41 (3.5%) patients. The average number of CRPs in patients with anterior semicircular canal BPPV was 2.19, which was higher than 1.60in those with posterior semicircular canal BPPV (p<0.0001). Canal conversion from anterior to posterior semicircular canal was found in 5 (12.1%) patients during treatment. The average number of CRPs in conversion cases was 4,which was higher than 1.94 in non‐conversion cases (p=0.001). Conclusion:More CRPs were necessary for the treatment of anterior semicircular canal BPPV than posterior semicircular canal BPPV. Canal switch could be considered as a factor to prevent a successful treatment.

Congenital ocular motor apraxia is a rare syndrome characterized by rotational head thrusts that attempt to compensate for the lack of voluntary eye movements. We describe the clinical, oculographic and magnetic resonance imaging features of two children with congenital ocular motor apraxia.

Objectives: This study was performed to evaluate the difference of the cervical vestibular evoked myogenic potentials (cVEMP) stimulated by bone-conduction (BC) and air-conduction (AC) in patients with nonspecific dizziness. Methods: Twenty-eight dizzy patients (56 ears) and 15 subjects (30 ears) as normal control was enrolled. Responses of BC- and AC-cVEMP were recorded sequen-tially in both groups. cVEMP parameters including latencies, inter-latencies intervals, amplitudes, and interaural amplitude asymmetry were analyzed and compared. Results: Among the patients with nonspecific dizziness, AC-cVEMP responses were clearly detected in all 56 ears while BC-cVEMP responses were detected in 32 ears (57.1%). Amplitudes of BC-cVEMP were significantly smaller than those of AC-cVEMP in all patients with BC-cVEMP response. There was no difference in latencies, inter-latencies intervals, and interaural amplitude asymmetry ratios between BC- and AC-cVEMP. There was no significant difference in BC- and AC-cVEMP between the dizzy and control groups. Conclusions: BC-cVEMP is not clinically useful in comparison to AC-cVEMP for the evaluation of nonspecific dizziness. An effective stimulation tool for BC is necessary to provoke more reliable responses of BC-cVEMP.

후반고리관 양성돌발두위현훈 환자에서 이석치환술 후 잔존하는 어지럼에 대한 DizzyFIX의 효용성

Background and Objectives: Benign paroxysmal positional vertigo (BPPV) is one of the critical life events that can affect physical, emotional, and functional aspects of quality of life. Canalith repositioning procedure (CRP) provides rapid and long lasting relief of symptoms in most patients with BPPV. However, some patients express nonspecific symptoms such as anxiety or discomfort after treatment, The purpose of this study was to assess the residual symptoms after CRP in patients with BPPV using Dizziness Handicap Inventory (DHI) in a questionnaire format and to evaluate the therapeutic efficacy of CRP according to accompanying the DizzyFIX device. Materials and Methods: We performed a prospective investigation in 135 consecutive patients with confirmed posterior semicircular canal BPPV. CRP was performed until nystagmus and vertigo disappeared. Patients were divided into three group using the DizzyFIX (group A), not using the DizzyFIX (group B) and closed observation (group C) after treatment. Then patients were asked to complete the questionnaire for Korean form DHI before treatment, 1, 2, 3, 4, 8 week after treatment. Results: There was a significant improvement in DHI scores when comparing the pre CRP and post CRP three groups (p<0.05), although emotional items showed incomplete improvement at 1 week. But at 2 week after treatment, there were statistically significant differences between group A and other groups in DHI scores specially in emotional items. Conclusion: Even after successful CRP, DHI scores indicated incomplete recovery and residual subjective symptoms may remain. For these patients additional follow up and management are necessary and using of the DizzyFIX will be helpful to reduce the incidence of residual dizziness especially emotional aspect.

양측성 전정기능 저하를 가진 환자에서의 전정재활치료

Bilateral vestibular deficit affects far fewer patients than unilateral deficit, and thus has been understudied. When bilateral vestibular organs are injured, loss of input of vestibulo-ocular and vestibulo-spinal reflex that normally stabilize the eyes and body, affected patients suffer blurred vision during head movement, postural instability, and disequilibrium. Vestibular rehabilitation therapy is an exercise-based treatment program designed to promote vestibular adaptation and substitution. The rationale for the exercises, which originated from the observation that patients who were active recovered faster, was based on the supposition that the head movements that provoke the patient’s dizziness play an important role in hastening the recovery process. Here the author reviews the clinical mani-festation and treatment of bilateral vestibular deficit that include vestibular rehabilitation therapy and vestibular device that studied today.

Anxiety, depression, or other psychiatric symptoms can be the primary cause of dizziness and the secondary complication of dizziness. Regardless of precedence or consequence, dizziness is closely associated with the psychiatric problem. On this ground, this chapter reviews the association between dizziness and anxiety and the treatment for dizziness with psychiatric symptoms.

Fluid Attenuated Inversion Recovery 영상에서 광범위한 염증성 삼출액소견이 선행되고 다발성 뇌신경 마비를 동반한 Ramsay-Hunt 증후군 1예

Ramsay-Hunt syndrome (RHS) is a well known disease caused by varicella-zoster virus infection in the geniculate ganglion of the facial nerve. Although the otic vesicle and facial palsy are easily recognized clinical signs of RHS, cases of associated multiple cranial nerve palsies present a difficult diagnostic challenge and furthermore, the mechanisms is unclear. We report a case of an 86-year-old man with otic crusted vesicles and peripheral typed facial palsy preceded by severe headache and fever. Several days later, he developed diplopia, dysphagia,hiccup and abdominal myoclonus. On fluid attenuated inversion recovery image of brain, diffuse subdural inflammatory exudates, which disappeared after treatment of acyclovir and corticosteroid, and ipsilateral facial nerve enhancement were observed in follow-up imaging.
