Background: Benign paroxysmal positional vertigo (BPPV) is a relatively common disorder, and is characterized by episodic vertigo and nystagmus which was provoked by head motion. However, little is known about the short and long-term outcome and the prognostic factors for recurrence of BPPV. In this pilot study, we tried to identify the prognostic factors of BPPV for short-term outcome. Methods: We analyzed clinical features of 32 patients (men=21, mean $age=60.4^{\circ}{\pm}12.6y$) with BPPV that was diagnosed by typical nystagmus induced by positioning maneuver. The induced nystagmus was recorded using video-oculography (VOG). According to the semicircular canal involved, BPPV patients were classified into horizontal, posterior, or anterior canal type. Univariate analysis for age, sex, and history of vertigo, and Kaplan-Meier analysis for each canal type were performed. Results: Horizontal (n=21, 65.6%) semicircular canal type BPPV was more common than the posterior one (n=11, 34.4%). Median follow-up period was 113 day (from 34 to 216 days). Four patients with horizontal canal type BPPV had recurrent attacks. Age, history of vertigo, and days prior to diagnosis were not different between canal type. Overall recurrence rate of horizontal canal type BPPV by Kaplan-Meier estimation was 19% at 60 days (p=0.13). Conclusions: Horizontal canal type BPPV was more common and recurred more frequently than posterior canal type in the present study. However, we did not find prognostic factors for recurrence of BPPV.

Benign paroxysmal positional vertigo (BPPV) is one of the most common clinical entities encountered in a dizzness clinic. Retrosepective review was performed for the patient's diagnosed as BPPV at Sunchon "S" hospital dizzness center. Variables for statistical analysis included age, sex, involved canal presence of recent head tramua, presence of chronic otitis media, history of middle ear surgery, underlying disease such as hypertension or diabetics, headache, central lesion. From July 2004 to May 2005, we sampled the 600 dizzness patient's who visited the dizzness center. Dizzness could be classified into BPPV, vestibulopathy. Among these patients, 256 patients had BPPV, 222 patients had vesibulopathy and 97 patients had Normal. Among these BPPV patients, 80 patients had lateral canalolithiasis BPPV (31.3%), 28 patients had lateral cupulolithiasis BPPV (10.9%), 90 patients had posterior canalolithiasis BPPV (35.2%), 7 patients had multicanalolithiasis BPPV (2.3%), 52 patients simultaneously had BPPV, other vestibular disease, and central lesion (20.3%).

Background and Objectives The early assessment of treatment is not done for benign paroxysmal positional vertigo (BPPV) since the well-known phenomenon of fatigability after a repeated positional test can mimic successful treatment. The aim of this study is to evaluate the clinical implication of 'fatigability' after Epley maneuver and to identify the therapeutic efficacy of Epley maneuver in posterior canal BPPV (PC-BPPV). Subjects and Method This study was prospectively conducted by two dizziness clinics on 51 consecutive patients diagnosed with PC-BPPV. All patients included in the study received Epley maneuver treatment. The therapeutic results were reassessed immediately after a single trial of Epley maneuver. After 30 minutes, results were reassessed repeatedly to confirm the fatigability of diagnostic procedure immediately after treatment. If the treatment was not successful after 30 minutes, Epley maneuver was repeatedly performed until complete resolution. Results Immediately after the first maneuver, 45 of 51 (88.2%) patients had neither vertigo nor nystagmus during the positional test. All patients demonstrated complete resolution after receiving one to three Epley maneuvers on the day of diagnosis. 'Fatigability (false negative result)' was confirmed for only one case (1 of 6 patients, 16.7%), in which nystagmus was observed after 30 minutes but not identified immediately after the first Epley maneuver. Conclusion The therapeutic efficacy of Epley maneuver is very high in PC-BPPV. Considering the possibility of fatigability when reassessment is performed immediately after therapeutic maneuver, clinicians should avoid assessing the outcome immediately after treatment in patients with PC-BPPV.

Purpose: Osteotome sinus floor elevation (OSFE) is an often-used technique of great utility in certain implant patients with resorbed posterior maxilla. Recently benign paroxysmal positional vertigo (BPPV) has been reported as an early postoperative complication following OSFE. Although OSFE-induced BPPV commonly resolves itself within a month without treatment, this complication can be a cause of trouble between the implant surgeon and patient. This report presents a case of BPPV following OSFE. Methods: A 27-year-old man without any significant medical problems and missing his maxillary right first molar, was scheduled for OSFE and simultaneous implant placement. Results: The patient suffered dizziness accompanied by nausea immediately after implant placement using OSFE. Following referral to the ear nose throat clinic, "right posterior canal BPPV" was diagnosed. Despite anti vertigo medication and a single episode of the Epley maneuver, the condition did not improve completely. The Epley maneuver was then applied 7 and 8 days later and the symptoms of BPPV disappeared. One year later, the patient remained symptom-free. Conclusions: Before sinus elevation with an osteotome, implant surgeons should screen out patients with a history of vertigo, to diminish the possibility of BPPV. Operators should be aware of BPPV symptoms. As the symptoms may be very incapacitating, immediate referral to an otorhinolaryngologist is recommended.

Benign paroxysmal positional vertigo(BPPV) is the most common peripheral vestivular disorder that is featured with paroxysmal vertigo caused by position changes. For a long time, it has been believed that the rendition is caused by inorganic particles in the cupula of the posterior semicircular canal. In the book 'DongyiSuseBowon(東醫壽世保元)', vertigo has been mentioned So-Yang-Sang-Pung syndrome and fever-aversive syndrome for Yin deficiency of So-Yang-In. Hyeong-Bang-Do-Jeok-San(荊防導赤散) is used at So-Yang-Sang-Pung and Gyeol-Hyung syndrome of So-Yang-In. Three patients in the cases have been suffered from vertigo, nausea and hot flushes etc. These patients were classified as So-Yang-In by features in the face, bodyshape and personality patterns. All of them have been improved in vertigo and other symptoms with Hyeong-Bang-Do-Jeok-San for a few days. The result showed that So-Yang-In Hyeong-Bang-Do-Jeok-San was effective on vertigo and other symptoms of BPPV patients.

순천성가롤로병원 어지럼증 센터에 내원한 어지럼증 환자 중 뒤반고리관 양성발작성 두위현기증은 머리나 몸을 움직일 때 갑자기 빙빙도는 느낌 또는 회전성 어지럼증을 호소하는 가장 흔한 질환이다. 대부분 환자들은 1회 치료로 증상이 호전된다. 하지만, 세 번 이상 여러번 치료를 요구하는 경우도 있다. 이석정복술에 의한 뒤반고리관 양성발작성 두위현기증환자의 어지럼증 증상 회복에 영향을 주는 인자을 분석하였다. 어지럼증환자 중 어지럼증 센터에 내원한 뒤반고리관 양성발작성두위현기증 환자를 분류하였다. 2008년 3월부터 2010년 11월까지 165명의 뒤반고리관 양성발작성두위현기증 환자 치료율을 조사하였다. 1회 치료성공율이 57.6%, 2회 치료성공율이 17.6%, 3회 치료성공율이 3.6%, 3회 이상 치료성공율이 21.2%였다. 뒤반고리관 양성발작성두위현기증 치료에 영향을 주는 인자는 외상 후, 내과적 질환, 뇌경색, 작은혈관 질환, 척추뇌바닥동맥기능부전증, 뇌혈관질환, 뇌질환, 안뜰신경염이다. 위와 같은 치료에 영향을 주는 인자들을 고려한다면 구토, 오심, 실신 등을 쉽게 치료 할 수 있을 것이다. 또한, 어지럼증 증상의 회복을 위한 이석정복술과 연관질환을 병행 치료하면 일상생활에 많은 불편함을 주고, 고통을 주는 어지럼증에서 호전될 수 있을 것이다. 앞으로 어지럼증을 유발하는 많은 인자들을 조사하고, 분석할 필요가 있을 것이다.

Background and Objectives: Bilateral sequential vestibular neuritis (BSVN) is a rare condition in which an inflammation or an ischemic damage of the vestibular nerve occurs bilaterally in a sequential pattern. We described four cases of BSVN. Subjects and Methods: Every patient underwent video-head impulse test during the first and the second episode of vestibular neuritis (VN), furthermore they have been studied with radiological imaging. Results: Contralateral VN occurred after a variable period from prior event. Vestibular function recovered from the first episode in one case. The other three patients developed contralateral VN. One case was due to a bilateral VN in association with a Ramsay-Hunt syndrome, in another patient clinical records strongly suggested an ischemic etiology, whereas in two cases aetiology remained uncertain. Two patients subsequently developed a benign paroxysmal positional vertigo involving the posterior canal on the side of the latest VN (Lindsay-Hemenway syndrome). Conclusions: Instrumental vestibular assessment represents a pivotal tool to confirm the diagnosis of VN and BSVN.
