Hearing loss in the contralateral functioning ear is a rare and distressing complication after vetibular schwannoma removal. Various possible mechanisms have been proposed, however, the etiology of hearing loss is not clear. Fortunately, this is an extremely rare occurrence, sporadic case reports have appeared in the literatures. We report two cases of acute contralateral hearing loss after vestibular schwannoma removal and discuss the possible mechanisms of the phenomenon. Although permanent deafness may result, in our cases, the hearing loss was temporary, returning to near preoperative level within one month. The etiology of hearing loss in one case is thought to be cerebrospinal fluid leakage. However, in the other case, the cause of hearing loss is not clear. A better understanding of these events may lead to preventive measures to avoid contralateral hearing loss after vestibular schwannoma removal.

Tinnitus is noise from ear or head without any external sound stimulation and can cause hearing difficulties, psychologenic disturbances or many difficulties in everyday life. the etiology has yet been discussed and the management is also very difficult. Sensorineural hearing loss is defined as a sudden hearing impairment which was develope over a period of hours to days. I report one tinnitus case which accompanied with sudden sensorineural hearing loss. In the early and acute stage which judged as Dam-Wha, herbal treatment with Tong-myeong-ri-gi-tang was efficacious on the tinnitus. In the convalescent stage and judged as Sin-heo, herbal treatment with Ja-sin-tong-i-tang was efficacious on the tinnitus that accompanied with sudden sensorineural hearing loss.

Epidural anesthesia has significantly advanced in neuraxial anesthesia and analgesia. It is used for surgical anaesthesia and treatment of chronic pain. Hearing loss during or after epidural anesthesia is rare, and it is known to occur by the change of the intracranial pressure. Cerebrospinal fluid is connected with perilymph in the cochlear and vestibule that is important to hearing and balance. If the intracranial pressure is abruptly transferred to the inner ear, perilymph can be leak, that called perilymphatic fistula, dizziness, and hearing loss can occur suddenly. We report a 65-year-old woman who presented with acute onset dizziness and hearing loss during the epidural nerve block for back pain, wherein we speculated a possibility of perilymphatic fistula as the mechanism of hearing loss and dizziness. The mechanism of dizziness and hearing loss was suspected with perilymphatic fistula.

Purpose: Kawasaki disease involves acute febrile systemic vasculitis that can cause a variety of symptoms by affecting various organs. Here, we aimed to evaluate the prevalence, causes, and prognosis of sensorineural hearing loss (SNHL) occurring in children with Kawasaki disease. Methods: Patients who were diagnosed with Kawasaki disease and received inpatient treatment in the Pediatrics Department at one of three university hospitals in Daegu city from February 2012 to September 2012 were enrolled in the study. The clinical features, hematological results, echocardiography results, audiometry results, and aspirin and salicylic acid serum levels of the patients were evaluated. Results: Of the 59 children enrolled in the study, three showed mild bilateral SNHL on audiometry tests conducted after 48 hours of defervescence; these patients demonstrated normal patterns of recovery on follow-up tests 8 weeks later. Aspirin serum levels were significantly higher in the SNHL group after 48 hours of afebrile condition with high dose aspirin intake (P=0.034). However, no significant differences were found in other laboratory tests or for fever duration (P>0.05). Upon echocardiography, coronary artery abnormality was observed in 9 cases, but none of these patients showed hearing loss. Conclusion: The results indicate that SNHL in children with Kawasaki disease might occur during treatment of the acute phase; this SNHL usually involves mild bilateral hearing loss and recovers naturally. However, this study suggests that determination of the causes and clinical implications of hearing loss in Kawasaki disease requires long-term follow-up studies with more cases.

Dizziness can be classified mainly into 4 types: vertigo, disequilibrium, presyncope, and lightheadedness. Among these types, vertigo is a sensation of movement or motion due to various causes. The main causes of peripheral vertigo are benign paroxysmal positional vertigo (BPPV), acute vestibular neuritis (AVN), and Meniere's disease. BPPV is one of the most common causes of peripheral vertigo. It is characterized by brief episodes of mild to intense vertigo, which are triggered by specific changes in the position of the head. BPPV is diagnosed from the characteristic symptoms and by observing the nystagmus such as in the Dix-Hallpike test. BPPV is treated with several canalith repositioning procedures. AVN is the second most common cause of peripheral vertigo. Its key symptom is the acute onset of sustained rotatory vertigo without hearing loss. It is treated with symptomatic therapy with antihistamines, anticholinergic agents, anti-dopaminergic agents, and gamma-aminobutyric acid-enhancing agents that are used for symptoms of acute vertigo. Meniere's disease is characterized by episodic vertigo, fluctuating hearing loss, and tinnitus. It is traditionally relieved with life-style modification, a low-salt diet, and prescription of diuretics. However, diagnosis and treatment of the peripheral vertigo can be difficult without knowledge of BPPV, AVN, and Meniere's disease. This article provides information on the differential diagnosis of peripheral vertigo in BPPV, AVN, and Meniere's disease.

Anterior inferior cerebellar artery(AICA) is a branch of the basilar artery which supplies the bloods for ventrolateral cerebellum and the lateral tegmentum of the lower two-thirds of pons. AICA occlusion can cause such symptoms as acute-onset unilateral deafness, vertigo, facial weakness and ataxia. A case of sudden hearing loss, facial palsy and vertigo caused by AICA territory infarction recently presented itself. Korean Oriental and Western medical therapy were applied in combination. Facial palsy and vertigo improved, but hearing loss did not improve. This case is reported with a brief overview of related literatures.

This paper was designed to investigate the causes of child hearing loss which is essential to language development especialy in young childhood. Accurate history taking, precise otolaryngological examination and impedence audiometry were performed on 185 hard of hearing children under age 5 during last 8 months and investigated its causes. The results were as follows: 1. Infections diseases were the most common causes of sensorineural hearing loss (44/123cases, 30.1%), and mother's condition during pregnancy the second, and birth injury or head trauma the third. 2. Acute or chronic ear ear diseases were the most common causes of counductive hearing loss (32/62, 51.6%), frequent URI the second (19/62, .30.6%), and adenoid vegetation the third (7/62, 11.3%). 3. The majority of causes of child hearing loss under age 5 was exogenous (179/185 cases, 96.8%), and the minority was endogenous (6/185 cases, 3.2%).

Background and Objectives: We aimed to analyze treatment outcomes following different initial management approaches and confirm treatment regimens for acute low-tone sensorineural hearing loss (ALHL) that would yield the best results. Subjects and Methods: We retrospectively analyzed the medical records of 106 patients with ALHL who visited a university hospital's otology clinic from March 2013 to June 2019. Pure-tone averages at the initial visit and at 2 and 4 weeks after the initial visit were evaluated. Results: Forty-nine patients were enrolled in this study; of them, 41 (83.7%) exhibited complete recovery (CR) at 2 weeks and 43 (87.8%) exhibited CR at 1 month after the initial visit. Regression analysis revealed that CR at 2 weeks after the initial visit was associated with diuretic use [Exp(B): 10.309, 95% confidence interval (CI): 1.007-100]. An initial daily low-dose steroid use was marginally significant [Exp(B): 1.042, 95% CI: 0.997-1.092; p=0.066]. Isolated diuretic use [Exp(B): 25.641, 95% CI: 1.121-90.909; p=0.039] was an independent, good prognostic factor at 1 month after the initial visit. However, other treatment regimens did not affect the final results. Conclusions: A combination of initial daily administration of ≤30 mg prednisolone plus diuretics was sufficient as the first-line treatment for ALHL. High-dose steroids and salvage intratympanic steroid injections can be applied as a second choice; however, the predicted outcome would not be good in that case.
