OBJECTIVES: Although many studies have assessed sudden deafness in adults, sudden deafness has not been evaluated in children. We therefore evaluated the differences in sudden deafness between children and adults. METHODS: We compared clinical manifestations, including gender, audiogram pattern of initial hearing loss, and recovery rate after treatment in 87 children and 707 adults diagnosed with sudden deafness from September 2003 and August 2012. RESULTS: There were no differences in sex, side, or audiogram between children and adults (P>0.05 each). Hearing recovery rates in children and adults were 72.4% and 70.6%, respectively (P>0.05). Both children and adults with mild hearing loss showed significantly greater hearing recovery rates than individuals with profound hearing loss (P<0.05 each). The percentage with initially mild and moderate hearing loss was higher in children than in adults, as were the recovery rates of children compared to adults with initially mild, moderate-severe, and profound hearing loss (P<0.05 each). In regard to final hearing outcome after treatment, a low percentage of children showed no improvement whereas a high percentage showed complete recovery; a higher percentage of children than of adults showed complete recovery (P<0.05). Recovery rate from profound hearing loss was significantly higher in children than in adults (60.0% vs. 45.4%, P<0.05). CONCLUSION: Degree of hearing loss, gender, side, and recovery rate were similar in children and adults, but the rate of complete recovery was higher in children.

3.Therapeutic Effects of Zinc on Patients Who Have Sudden Sensorineural Hearing Loss with Normal Serum Zinc Level.
Korean Journal of Otolaryngology - Head and Neck Surgery 2015;58(12):831-835
BACKGROUND AND OBJECTIVES: Zinc has antioxidant effect, anti-inflammatory effect and neuromodulative function. The purpose of this study was to investigate whether treatment with zinc can improve the outcome of sudden sensorineural hearing loss (SSNHL). SUBJECTS AND METHOD: The study group consisted of 143 patients diagnosed as SSNHL. Of the patients, 82 were given corticosteroid treatment (group Ct) and 61 were given oral zinc plus corticosteroid treatment (group Zn). In group Zn, serum zinc level was checked before treatment and the patients with normal serum zinc level were included. Hearing was assessed before therapy and at 2 weeks, 1 month and 2 months after the initiation of therapy. RESULTS: A significantly larger hearing gain in pure tone average (group Ct vs. group Zn=26.40 dB HL vs. 34.28 dB HL) and at 2000 Hz (group Ct vs. group Zn=24.93 dB HL vs. 33.60 dB HL) and 8000 Hz (group Ct vs. group Zn=11.64 dB HL vs. 20.66 dB HL) were seen in group Zn compared with the group Ct. CONCLUSION: Oral zinc supplementation may have beneficial effects in the treatment of SSNHL, especially at 2000 and 8000 Hz.

Salicylate, the active ingredient of aspirin can cause sensorineural hearing loss and tinnitus when plasma concentrations reach a critical level. The ototoxic mechanisms of salicylate remain unclear but hearing and tinnitus usually recovers a few days after intoxication. There have been few reports of salicylate-induced ototoxicity in Korea, and the majority is caused by a low dose of aspirin. Herein, we report a case of sudden hearing loss and tinnitus after acute salicylate intoxication and review recent updates on salicylate ototoxicity.

8.Intratympanic Steroid Therapy for Sudden Sensorineural Hearing Loss.
Korean Journal of Audiology 2011;15(2):53-61
While systemic steroid therapy is most widely considered as a main treatment for idiopathic sudden sensorineural hearing loss (SSHL), the disadvantages of its use are numerous side effects. Intratympanic steroid injection (ITS) delivers steroids through transtympanic route, hence avoids possible side effects with higher perilymph concentration. We conducted a reviewed 47 clinical studies after an online search of the PubMed databases for the following terms "sudden hearing loss, intratympanic steroid". Although the study settings are varied among reviewed articles, most studies in this review consistently showed some benefit of hearing in salvage cases. In addition, it is suggested that intratympanic steroids are equivalent to systemic steroid therapy as initial treatment for SSHL. In patients with contraindications against the use of systemic steroid, ITS may be considered as valuable option for primary therapy. Further studies are necessary to elucidate the optimal protocol of administration.

BACKGROUND AND OBJECTIVES: The prognosis and prognostic factors for acute acoustic trauma are difficult to predict. The aim of this study was to assess the prognostic factors of acute acoustic trauma. SUBJECTS AND METHOD: The cases selected for this report are 27 patients with acute acoustic trauma and 139 patients with sudden deafness are selected for control group. The following factors were examined for prognostic factors: age, vestibular symptom, degree of initial hearing loss, number of days before 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.
