- Background
and Objectives :Benign paroxysmal positional vertigo (BPPV) has a lot of causes. Except idiopathic BPPV, the most common cause of BPPV was trauma. The aim of this study was to study its character, diagnosis, prognosis and treatment.
Materials and Method : We retrospectively collected the 14 patients by reviewing charts, analyzing vestibular function tests.
Results
: Post traumatic BPPV had characters different from idiopathic BPPV in patient' sex ratio and age distribution. The mean age of patients was 40 years old, men were 11 women were 3. In the mechanisms of trauma, traffic accidents were 11, assault was 1, and fall down were 2. In types, posterior semicircular canal were 10, horizontal semicircular canal were 4. In origins, cupulolithiasis were 8, canalolithiasis were 6. Treatment and prognosis were similar to those of idiopathic BPPV.
Conclusion
: But origin, diagnostic criteria, treatment and prognosis are identical with idiopathic BPPV. Therefore, in evaluating post traumatic BPPV patients, we need correct diagnosis and treatment together by history taking, physical examination and vestibular function tests. And by this, we can treat idiopathic BPPV accurately, reduce expense and time for patients to return daily life.

Abstract
PDF
- Background
: Acute vestibular neuronitis is the disease of which the etiology and pathophysiology are largely
unknown . But the viral infection and ischemia of the labyrinth and the vestibular nerve are considered as general
etiology. This study was performed to support the viral infection rather than the ischemic theory.
Materials & Methods : We studied seventy years old female patient who showed painful vesicles on left auricle
and vertigo with spontaneous nystagmus to the right side. We performed physical examination, serologic test, ENG test,
pure tone audiogram, brain magnetic resonance imaging and polymerase chain reaction.
Results
: We found small vesicles and vascular injection in left EAC, herpes zoster IgG positive, spontaneous right
beating in electronystagmograpy, 54% left canal paresis in Caloric test , decreasing left side Tc in velocity step rotatory
test, decresed gain, deviation to left in symmetry and phase lead in sinusoidal harmonic acceleration test, normal range
hearing in pure tone audiogram, microangiopathy on cortex in brain MRI and negative PCR.
Conclusion
: This case supports viral infection etiology rather than ischemia in vestibular neuritis. But more studies
to find the etiology of vestibular neuronitis are required.
Key Words : Herpes zoster oticus, Vestibular neuronitis.

Abstract

- Background
and Objectives: Labyrinthine fistula is one of the common complication of the chronic otitis media with cholesteatoma. Disruption of the labyrinthine bone can lead to hearing loss and/or vestibular disturbance. This study aimed to evaluate postoperative vertigo result in patient with labyrinthine fistula and efficacy of vestibular function test for diagnosis.
Materials and Method: A retrospective study of the clinical records of 13 patients who were operated for chronic otitis media with cholesteatoma, suspected to have secondary labyrinthine fistula, from January 2001 through June 2003 in Gachon medical school Gil hospital. All patients were evaluated by Fistular test, Vestibular function test, high resolution Temporal bone CT, Pure tone audiometry preoperatively. Vertigo was assessed by Disability Scale.
Results
Canal wall down mastoidectomy were applied in all ears. Labyrinthine fistulas were confirmed in 8 patients during operation. Fistular group had higher rate of peripheral vestibular injury than no-fistular group's in vestibulo-ocular reflex. Fistula cases have high average score (2.9) than non-fistula's (1.6) in Vertigo scale preoperatively. In post-operation, the average score was 0.25 in fistular cases and 0.4 in non-fistula cases. 2 cases presented positive fistular test result (25.0%)
Conclusion
Although Vertigo was more severe in patients who had fistula, in post-operation, symptoms could be relieved a lot. Vestibular function test had efficacy for diagnosis of labyrinthine fistula in preoperative.
