Infectious mononucleosis, a comon systemic illnes primarily involving children and young adults, is due aparently to the Epstein-Bar virus (EBV). Although neurologic complications of infectious mononucleosis are rare, these include meningoen-cephalitis, Guillain-Barre syndrome and mononeuritis, and facial nerve paralysis. Bilateral facial nerve palsy rarely develops in patients with a primary Ebstein-Barr virus (EBV) infection, and only a few of these have clinical manifestations of infectious osis.

Canalith repositioning procedure (CRP) provides rapid and long-lasting relief of symptoms in most patients with benign paroxysmal positional vertigo (BPPV). However, some patients express nonspecific symptoms such as anxiety or discomfort after CRP, even after the disappearance of nystagmus and vertigo. The purpose of this study is to assess the residual symptoms after CRP in patients with BPPV using questionnaire. Subjects and Method:CRP was performed in 135 patients until nystagmus and vertigo disappeared, and the patients were asked to complete the Dizziness Handicap Inventory (DHI) before and five to seven days after treatment. For the control group, 135 normal volunteers were selected, and cross matched according to the age and sex with the patient group. The DHI were compared among pre CRP, post CRP and control group. Results: There were statistically significant differences between the pre-CRP and post-CRP DHI scores and also between the post-CRP and control group. Comparison between the pre and post-CRP DHI scores, and post-CRP and control group both showed incomplete improvement with respect to some items. Conclusion:Even after the successful CRP, DHI scores indicated incomplete recovery and residual subjective symptoms was presented. Thus, additional follow up and management may be needed.

Otosclerosis is a primary metabolic bone disease of the otic capsule and ossicles. It is one of the causes of acquired hearing loss, h the cause of otosclerosis is undetermined, the disease has a well established hereditary predisposition, with approximately half of all affected individuals having family members known to be affected. Many genetic studies of otosclerosis support an autosomal dominant mode of inheritance with penetrance in the range of 20- 40%. There have been a few reports of the clinically suspicious otosclerosis cases in Korea, bu cle-rosis. (Korean J Otolaryngol 2007 ;50 :182-5)

전정신경염에 대한 평가와 진단

반재호,안용휘 대한평형의학회 2011 Research in Vestibular Science Vol.10 No.-

Vestibular neuritis presents as a sudden onset of rotary vertigo with associated nausea, vomiting, and generalized imbalance. In general, the dizziness lasts from a few hours to several days with gradual, definite improvement throughout the course. Vestibular neuritis is now considered to be the more accurate term for cases that do not involve hearing loss. The diagnosis of vestibular neuritis depends on the history of spontaneous, prolonged vertigo, physical findings that are consistent with a unilateral peripheral vestibular paralysis, and the absence of other neurological symptoms and signs. History and physical examination alone are usually adequate for diagnosis, although one must ensure that a central insult is not at fault. Relevant differential diagnoses are pseudo-vestibular neuritis due to acute pontomedullary brainstem lesions or cerebellar nodular infarctions, vestibular migraine, sudden sensorineural hearing loss accompanies vertigo with a vestibular neuritis-like pattern and monosymptomatically beginning Meniere's disease. Vestibular function tests including caloric test, vestibular evoked myogenic potential are useful to identify the side of involvement and to localize the pathology to the inferior or superior vestibular nerve.

Congenital midle ear cholesteatoma is a keratinizing squamous epithelial cyst that classically presents as a white pearl in nital cholesteatoma depend upon the initial site of the disease. The most comon presentation of this disease is a conductive hearing los or a facial palsy of gradual onset. Other presentations include incapacitating vertigo with nystagmus, a feeling of fullnes in the ear, frequent otalgia, an abnormal eardrum noted at physical examination for an unrelated condition and meningitis. Recently, we experienced a case of congenital cholesteatoma that was presented as a post-auricular fistula. In considering the

Background and Objectives: The purpose of this study is to investigate the change of vocal tract length according to the level of the pitch by the singers. Materials and Methods: Fifteen tenors were asked to produce successive /a/ sound in G4(382Hz) for the head register, C3(131Hz) for the chest register and usual speaking sound. The control group consisted of 15 males of an similar age who are not professional singers. The length of vocal tract was calculated by applying the formula of Fn=(2n-1) c/4L(F : formant frequency, c : the speed of sound in the vocal tract(350m/sec), L : length of vocal tract, $n=1,2,3,4,{\ldots}{\infty}$). Results: In singer's group, there showed no significant statistical difference of length among head and chest register and usual speaking sound. However in the control group, there showed statistically significant difference of length. Comparison of the absolute difference in the length of vocal tract by changing level of pitch in phonation, between the control group and the singers group. Changing from G4 phonation to C3 phonation and C3 phonation to usual speaking sound showed statistically difference of vocal tract length was less in the singers group than the control group. Conclusion: The change of vocal tract length, in either speaking or singing, was less in singers than the control group. We could assume that the singers maintain their larynx position constantly throughout the pitch range when phonation.

This study was conducted to review the clinical features of fungal sinusitis and to evaluate the effectiveness of transnasalendoscopic sinus surgery as a primary surgical method for treating fungal sinusitis. Eighty five patients (86 cases) who weretreated for fungal sinusitis with transnasal endoscopic sinus surgery between 1993 and 2004 were retrospectively analyzed byreviewing their profile, which included clinical feature, surgical techniques, operative findings postoperative results and complications. All patients were adults consisting of 30 males and 55 females. All cases were treated successfully by transnasalendoscopic sinus surgery. No recurrence and postoperative complication were observed. However, in 18 cases, fungal debrieswere observed when sinus irrigation was done at primary follow-up. In these cases, fungal debris disappeared at postoperative1.7weeks (average) and no recurrence was observed. Transnasal endoscopic sinus surgery is successful method in thetreatment of non-invasive fungal sinusitis.

Central vertigo of cerebellar origin may present the syndromes similar to those of peripheral vertigo such as vestibular neuronitis. The character of those vertigo syndrome depend on the location, extent, and the etiology of the lesion such as stroke, inflammation, mass. Cavernous hemangioma may be clinically silent, but can cause variable neurologic manifestations including central vertigo if it affects the vestibular system. We report a rare case of cerebellar cavernous hemangioma with the vertigo syndrome closely mimicked vestibular neuronitis.
