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 associated with the degree of hearing recovery from sudden deafness. MATERIALS AND METHOD: We reviewed the records of 110 patients who were admitted for treatment between 1999 and 2001 under the initial diagnosis of idiopathic sudden hearing loss. Patients were classified 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, immunologic group, cochlear neurologic group, and the other group. RESULTS: Patients who had cardiovascular hematologic factors and cochlear neurologic factors showed lower recovery rates than the other patients. Patients with metabolic factors showed higher recovery rate than those with other factors. CONCLUSION: These results suggest that cardiovascular hematologic factors and cochlear neurologic factors might be most significantly related with prognosis in sudden deafness patients.

BACKGROUND AND OBJECTIVES: Sudden deafness in children is rare and comprises less than 10% of all sudden deafness. Viral infection is more common and early treatment is less common in children than in adults. Prognosis of sudden deafness 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 40 patients (41 ears) who had been admitted to the department of otolaryngology, Pusan National University Hospital from January 1990 to December 2000. 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 degree of hearing loss than in those with the other degrees of hearing loss (p<0.05). 3) The patients who had been treated within 7 days after the on-set of 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 deafness and viral infections are more common 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.

Low frequency sensorineural deafness is a common subtype of idiopathic sudden deafness. Certain patients suffered recurrent attacks without vertigo, much alike Meniere's disease. Few of them developed into definite Meniere's disease during long-term follow-up in many clinical studies. Although the pathophysiology of recurrent low frequency deafness is yet unknown, the desease is considered associated with early state of endolymphatic hydrops or migraine. Otologists shall be aware of its clinical course and careful explanation is necessary at time of initial informed consent.

OBJECTIVES: Ménière disease is a clinical syndrome characterized by the four major symptoms of episodic vertigo, sensorineural hearing loss, tinnitus, and aural fullness. Sensorineural hearing loss, especially low frequency, is the characteristic type of audiogram in Ménière's disease. However, it is difficult to distinguish idiopathic sudden sensorineural hearing loss (ISSNHL) with vertigo from the first attack of Ménière disease. The purpose of this study was to investigate the incidence of progression into Ménière Disease from low frequency ISSNHL. METHODS: Two hundred eighty-three patients were included in this study. We classified the patients with ISSNHL according to the hearing loss in audiogram and analyzed how many of them actually progressed to Ménière disease based on diagnosis criteria. RESULTS: Among the 240 patients, 37.1% (89 patients) were confirmed low frequency ISSNHL and 14.6% (13 patients) of them were diagnosed with Meniere disease. CONCLUSIONS: This study showed that the progression from low frequency ISSNHL to Ménière disease was higher than other frequency ISSNHL, as in other studies.

OBJECTIVE: To evaluate the characteristics and prognosis of sudden sensorineural hearing loss through vestibular evoked myogenic potentials. METHOD: Fifty patients with unilateral sudden hearing loss underwent an ear test battery, including audiometry, cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential(oVEMP). The cVEMP and oVEMP in patients with sudden sensorineural hearing loss were investigated. Their associations with initial hearing threshold, the type of audiogram, the results of coloric test and hearing recovery were also accessed. RESULT: After one-month treatment, the average threshold declined significantly in affected ears, with normal VEMP rates improved significantly (P < 0.05). Initial hearing threshold and hearing recovery were significantly associated with the results of coloric test and the results of VEMP test (P < 0.05). CONCLUSION Our study indicated that vestibular evoked myogenic potential examination was not only a useful additional diagnostic tool in the neurotological evaluation of patients suffering sudden hearing loss, but also very valuable in the prognosis of sudden sensorineural hearing loss.
