- Canalith repositioning maneuver is effective to treat benign paroxysmal positional vertigo(BPPV). This case showed
complicated form of the BPPV such as changes of canalolithiasis to cupulolithiasis, involvement of one canal to two
canals and from unilateral to bilateral involvement during the reposition maneuver.
This patient was diagnosed as left lateral canalolithiasis at first. After left barbecue maneuver, the type was changed
to the right posterior cupulolithiasis. Semont maneuver was performed and then the type of BPPV was changed to
combined type with right posterior canalolithiasis and left lateral canalolithiasis. We performed left barbecue maneuver
and right Epley maneuver. Then the type of BPPV was changed to left lateral cupulolithiasis. After Brandt-Daroff
maneuver and left barbecue maneuver, nystagmus and dizziness disappeared finally.

- Background
and Objectives: Psychogenic dizziness has not been studied extensively in Korea while it is seen frequently. We investigated the prevalence of psychiatric diagnosis and the results of vestibular function testings in patients with the diagnosis of psychogenic dizziness at a Korean tertiary university hospital.
Materials and Methods: The study was conducted on 38 patients with the diagnosis of psychogenic dizziness. They all received vestibular function testings (ENG, rotating chair test and posturography). Patients with central or vestibular organic disease were excluded from this study.
Results
Somatoform disorder was the most common psychiatric disorder causing psychogenic vertigo(47.4%) in this study. Anxiety disorder(21.1%) and depression(21.1%) were the next common causes. The vestibular function testings were abnormal in 19 patients(50.0%). The electronystagmography in 11, rotating chair test in 6, and posturography in 14 patients were abnormal.
Conclusions
Somatoform disorder was the most common psychiatric disorder and vestibular function tests were abnormal in 50% of psychogenic dizziness patients. It implies that the patients with psychogenic dizziness have functional abnormalities in vestibular system.
