Background and Objectives:Suden deafness in children is rare and comprises less than 10% of al sudden deafness. Viral infection is more comon and early treatment is les comon in children than in adults. Prognosis of sudden deafnes is poorer in children than in adults. This study was attempted to evaluate clinical characteristics and prognosis of sudden deafness in children and to compare with sudden deafness in adults. Materials and Methods:We reviewed the records of (41 ears) who had been admitted to the department of otolaryngology, Pusan National University Hospital from January 1990 to December 20. Results:1) Hearing recovery was significantly worse in the age group below 10 than in that over 10 (p<0.05). 2) Hearing recovery was less favorable in patients with profound degre of hearing loss than in those with the other degres of hearing loss (p<0.05). 3)symptoms were smaller in children than in adults (p<0.05). 4) Mumps was more common in childhood, the hearing recovery was significantly worse in cases with mumps than those without mumps (p<0.05). 5) Of the 41 ears, 8 ears (19.5%) had complete recovery, 5 ears (12.2%) had partial recovery, 9 ears (22.0%) had slight improvement, 19 ears (46.3%) had no improvement. Conclusion:Congenital hereditary deafnes and viral infections are more comon in children. Thus the cause of sudden sensorineural hearing loss can be identified more frequently in children than in adults. Poor hearing recovery in children are considered to be associated with late time of initial treatment and asymptomatic mumps. Early diagnosis and early treatment are more important in children.

Background: Both stellate ganglion block (SGB) and polarized light irradiation (Superlizer) have a tendency to increase blood flow. Increases in blood flow can be estimated indirectly by changes in tympanic membrane temperature. In this study, we sought to evaluate how simultaneous SGB and Superlizer treatment affects tympanic temperature and tympanic blood flow in individuals suffering from sudden deafness. Methods: Among patients who visited the pain clinic complaining of sudden deafness, we divided them into two groups: one receiving only SGB; the other receiving both SGB and Superlizer treatment. By comparing the tympanic membrane temperature measurements of both groups on 10, 30, and 60 minutes after treatment through a prospective study, we intended to evaluate the effect of treatment with SGB and Superlizer. Results: Temperature changes measured after the injection were statistically significant in both groups. Temperature changes of the tympanic membrane were greater in the group who received both SGB and Superlizer compared to the group receiving only SGB. Conclusions: The results suggest that SGB followed by Superlizer has effects on the amount of increase in tympanic membrane temperature. This seems to be attributed to the increase in blood circulation of the inner ear compared with the group receiving only SGB. We came to the conclusion that in sudden deafness patients,the use of SGB combined with polarized light irradiation appears to be more effective in the treatment of sudden deafness.

Benign paroxysmal positional vertigo (BPPV) is a disorder caused by otoconia in the inner ear. Its symptoms are repeated episodes of positional vertigo, that is, of a spinning sensation caused by changes in the position of the head. BPPV with simultaneous ipsilateral sudden deafness is rare. A 82-year-old woman was admitted due to acute onset of right ear hearing impairment, tinnitus, and vertigo for a day. She had a history of hypertension for 5 years. On neurologic examination, spontaneous nystagmus was not observed. However, roll test showed direction-changing horizontal geotrophic nystagmus. Vestibular function test showed positional nystagmus compactable with right horizontal semicircular canal-BPPV (canalolithiasis). Brain MRI was unremarkable. Neuro-otologic evaluation reveals right ear sensorineural deafness. Barbecue maneuver was applied for treatment for BPPV. Dexamethasone 10 mg intravenous for 5 days after then methylprednisolone orally for 5 days was done. Vertigo improved after treatment, but deafness still remain. We report a case of sudden deafness concurrent with ipsilateral BPPV and consider the mechanisms of this lesion.

Background and Objectives:There are lots of debates regarding the prognostic factors in sudden deafness patients. The aim of this study is to identify prognostic factors that might be asociated with the degre of hearing recovery from sudden deafness. Materials and Method:We reviewed the records of 110 patients who were admitted for treatment betwen 1999 and 2001 under the initial diagnosis of idiopathic sudden hearing loss. Patients were clasified into following subgroups based on the data of our own diagnostic protocol, including history taking, physical examination and laboratory tests:cardiovascular hematologic group, infectious group, metabolic group, imunologic group, cochlear neurologic group, and the other group. Results:Pa-patients. Patients with metabolic factors showed higher recovery rate than those with other factors. Conclusion:These results sugest that cardiovascular hematologic factors and cochlear neurologic factors might be most significantly related with prog-nosis in sudden deafness patients.

Background and Objectives:The prognosis and prognostic factors for acute acoustic trauma are difficult to predict. The aimof this study was to assess the prognostic factors of acute acoustic trauma. Subjects and Method:The cases selected for thisreport are 27 patients with acute acoustic trauma and 139 patients with sudden deafness are selected for control group. Thefollowing factors were examined for prognostic factors : age, vestibular symptom, degree of initial hearing loss, number of daysbefore the start of treatment. Results:Most strongly related factor for prognosis is number of days before the start of treatment,but other factors are not significant relation for prognosis. The overall hearing recovery rate of acute acoustic trauma was 29.6%and that of sudden deafness is 56.1%. Conclusion:Early treatment of acute acoustic trauma increases hearing recovery rate,and acute acoustic trauma has worse prognosis than sudden deafness. (Korean J Otolaryngol 2006;49:494-8)

Background and Objectives Dizziness has been known as a prognostic factor in suddensensorineural hearing loss (SSHL), but it is difficult to describe and quantify its subjectivesymptoms. Also, dizziness itself cannot imply vestibular dysfunction in SSHL. Comprehensiveevaluation of vestibular function may help us understand the extent of lesions in sudden deafness. The purpose of this study is to determine whether an impaired caloric response is associatedwith disease severity and hearing outcome. Subjects and Method A retrospective chart review was conducted of 488 patients diagnosedas unilateral SSHL. The patients were divided into two, an abnormal caloric group (canal paresis>20%) and normal caloric group (canal paresis ≤20%). Initial demographic and audiologicfindings and final hearing outcomes were compared between the two groups. Results The initial pure tone averages of SSHL patients of abnormal caloric group and normalcaloric group were 75.4±28.4 dB HL and 68.2±25.4 dB HL (p=0.004), respectively. Patientsof abnormal caloric test group showed worse hearing outcome across all frequenciescompared to those of the normal caloric group. Also, a significant correlation was noted betweenthe magnitude of hearing recovery and canal paresis (r=-0.223, p<0.001). Conclusion SSHL patients of abnormal caloric test showed worse initial hearing level andpoorer hearing outcome. Evaluation of vestibular function in SSHL patients is important becausesubjective symptoms alone cannot account for vestibular hypofunction patients, and thecaloric test can help in the counseling of patients and prediction of hearing outcome in SSHLpatients.

Background and Objectives Sudden deafness, an important disease characterized by abrupt sensorineural hearing loss, is rare in children and the prognosis in children is accepted to be worse than that in adults. However, clinical studies are not sufficient to define the clinical characteristics and prognosis of sudden deafness in children. The author analyzed clinical manifestation of sudden deafness in children and compared the treatment results of children with those of adults. Subjects and Method A retrospective analysis was performed in 25 patients (29 ears) who were treated for sudden deafness from January 1993 to May 2008. Results 1) The overall hearing recovery rate (79%) was significantly higher in adults (53.7%). The prognosis in children less than 10 years old (73%) was also higher than that in adults. 2) The rate of complete recovery (61%) was higher in children than in adults (38.5%). Conclusion The sudden deafness in children has unique clinical characteristics and the recovery rate is more favorable than in adults.

Backgrounds : sudden sensorineural hearing loss is defined as a disease that has abrupt onset of sensorineural hearing loss without definite cause. In some cases, this disease cause tinnitus, vertigo, headache addition to hearing loss. In traditional oriental medicine, sudden sensorineural hearing loss is could be diagnosed as deficiency of Yang-Gi(陽氣). Objects & Methods : This study is clinical observation about three sudden sensorineural hearing loss cases. For diagnosing in these cases, pure tone audiometry was used. For treatment, acupuncture, herbal-medicine and moxibustion therapy were used. Results & Conclusions : as follows. 1. Generally, in this disease, the shorter the whole period from the time that occurs to the time that starts to treat is, the more the results are better. The research shows that short-term case is more efficient than the other long-term two cases in the aspects of symptoms and pure tone audiometry . 2. In making a diagnosis of sudden sensorineural hearing loss and measuring the effect, subjective symptoms generally correspond to the improvement of pure tone audiometry, but not completely. Therefore, in treating patients, the doctor must consider these both aspects and keep the balance.
