Massive ovarian deema is a tate conditian. It is a benign enlargement of the ovary caused by accumulation of fluid, which is thought to result from intermittent partial toraion of the ovarian pedicle. Histologically, the ovaries were characterized by diffuse edema of medulla and inner cortex. Two cases of massive ovanan edema are reported with brief review of the literatures.

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.

Journal of the Korean Balance Society 2004;3(1):150-155
BACKGROUND AND OBJECTIVES:Traditionally, down beat nystagmus is regarded as a sign of central nervous system dysfunction. But, several years has passed since Herdman et al reported the down beat nystagmus developed during treatment maneuvers for posterior semicircular canal benign paroxysmal positional vertigo(BPPV). We undertook this study to evaluate the character and clinical analysis of the positional or positioning down beat nystagmus, to discuss the clinical significance of positional or positioning down beat nystagmus as a diagnostic criteria of superior semicircular canal BPPV, and to propose the new treatment method. MATERIALS AND METHOD:From November 1999 to March 2004, we sampled the 103 patients with positional or positioning down beat nystagmus. Of these patients, we selected 16 patients except for the patients with central nervous system dysfunction, nonspecific or artifact result, idiopathic origin. RESULTS:All of 16 patients had no sign and radiologic result of central nervous system disorder. 10 patients was reported or suspected the diagnosis of posterior semicircular canal BPPV. Fatigability was reported in 9 patients and reversibility was reported in 1 patient. Average latency was checked less than 2 seconds. CONCLUSION:Although the diagnostic criteria of superior semicircular canal BPPV that we reported was not controversial, we expect that this criteria is useful in diagnosis for patients with atypical positional or positioning down beat nystagmus. And the new treatment method that we reported will has the better results than previous method.

5.Analysis of Vertical Semicircular Canal Rotational Test in Healthy Adults.
Korean Journal of Otolaryngology - Head and Neck Surgery 2000;43(5):482-487
BACKGROUND AND OBJECTIVES: Vestibular function tests of the semicircular canal (SCC) are limited to horizontal SCC since stimulating a vertical SCC is difficult. The purpose of this study is to develop a vestibular function test of vertical SCC and analyze its function in healthy adults. MATERIAL AND METHODS: Thirty healthy adults were placed down in supine position on a rotating table with their heads turned 45 degrees to left or 45 degrees to right side. The table was rotated in a sinusoidal rotational mode at 0.05 Hz and 0.1 Hz frequency. Nystagmus was observed through a videooculographic device or Frenzel glasses and recorded with a romputerized electronystagmography. An analysis was made on the vertical nystagmus. RESULTS: Rotatory nystagmus was observed: the slow component of eye velocity and the gain were increased at a higher frequency while the phase was decreased at higher frequency (p<0.05). Gain, phase and directional preponderance did not show any significant difference at each head position. CONCLUSION: Resulting nystagmus from the rotating chair stimulation on a vertical SCC has been analyzed. The test can be utilized to analyze the function of a vertical SCC as a positional/positioning test, a head impulse or self rotation test.

Albinism is a hereditary disease caused by the defect of tyrosinase that converts tyrosine to dihydroxyphenylalanine (DOPA). `Oculocutaneous albinism' is classified as hypopigmentation of skin, hair and eyes, but incidences of `ocular albinism' where hypopigmentation is limited to eyes are found rarely. Biochemically, albinism is caused by the tyrosinase activity. Typical findings in oculocutaneous albinism include not only ophthalmologic problems such as hypopigmentation of skin, foveal hypoplasia, photophobia and decreased visual acuity but also congenital nystagmus. We cannot determine distinctive characteristics of nystagmus of albinism because domestically, there are only a few reports that have been recorded correctly about nystagmus of albinism. Merely, we present our experience of two cases of albinism with congenital nystagmus because we think that these two cases, showing different types of nystagmus and electronystagmography, stand for the two representative types of nystagmus found in the literature up to date.

7.Otoplasty in Otolaryngology.
Korean Journal of Otolaryngology - Head and Neck Surgery 2013;56(7):406-417
Otoplasty is known to be a challenging and rewarding area in otolaryngology. Although the physiologic effects of ear deformity are negligible, the aesthetic and psychological impact on the patient can be profound. Protruding, thin auricle of the ear is prone to damage from craniofacial trauma. The degree of damage varies, requiring immediate treatment and management. In order to obtain favorable results from otoplasty, having firm knowledge on the anatomy and embryology of the external ear must be preceded prior to meticulous assessment and assiduous operative planning for deformity of external ear and auricular injury. Anesthetic correction of the ear through diagnosis and subsequent treatment of the affected ear must also be performed. This study summarizes anatomic and embryologic analysis of the external ear and auricular deformities and trauma. In addition, a great number of surgical techniques for the otoplasty is reviewed to provide higher satisfaction for both patients and surgeons.

We reviewed 14 children with unilateral fractures of femoral shaft who had an angular deformity after union of 10° to 25°. At an average follow-up of 32 months(15 to 65), we measured remodelling of the proximal physis, the distal physis and the femoral shaft. The average correction was 83% of the initial deformity and there was no relation between the remodelling rate and degrees of malunion. Of the correction of angulation, only 27% had occurred at the fracture site and 73% at physis. The ability of physis to remodel better than that of fracture site. In children under 13 years of age, malunion as much as 25° in flexion deformity will remodel enough to get normal alignment of the joint surfaces.

Journal of the Korean Balance Society 2002;1(1):113-117
BACKGROUND AND OBJECTIVES : Ageotrophic nystagmus in the horizontal canal BPPV has been explained as a result of cupulolithiasis theory, and has been reported to have the less therapeutic response to conservative rehabilitations than the other type BPPV . Though methods to detach the debris with vibrator have been introduced, the effect has been questioned and it's not physiologic. MATERIALS AND METHOD : We introduce a new head shaking-forced prolonged position method as a more convenient method, and report typical 2 cases of ageotrophic horizontal canal BPPV managed with it and analyzed results of 25 cases all told. RESULTS AND CONCLUSION : The average number of rehabilitation was less than two, and loss of direction changing positional nystagmus could be observed immediately after rehabilitation.

10.Laboratory Vestibular Function Testing.
Journal of the Korean Medical Association 2008;51(11):975-983
Basically laboratory vestibular function testing use the vestibular ocular reflex and vestibular spinal reflex like as bedside examination or outpatients' evaluation. Such vestibular laboratory testing can aid diagnosis and can be used to document an abnormality suspected at bedside evaluation. The ability to perform serial vestibular evaluations allows an assessment over time of patients who are undergoing treatment for dizziness or treatment with potentially ototoxic medication. Generally speaking, it includes spontaneous nystagmus, some kinds of evoked nystagmus, ocular eye movement testing, Caloric's testing, rotational chair testing, vestibular evoked myogenic potential, subjective visual vertical, posturography and so on. Those testing have been developed with biomedical engineering based on the proven scientific facts together.
