Ah Young PARK ; Ju Hyun JEON ; In Seok MOON ; Jae Young CHOI

Korean Journal of Audiology.2014;18(2):93-96. doi:10.7874/kja.2014.18.2.93

The Vibrant Soundbridge (VSB) with stapes clip coupler placement at the stapes head has been used successfully to treat mixed hearing loss. Coupling between the floating mass transducer of the VSB and the stapes head is technically less demanding than incus vibroplasty and is more likely to generate a positive outcome without significantly changing residual hearing or resulting in medical or surgical complications. A 65-year-old man with bilateral mixed hearing loss and chronic otitis media underwent vibroplasty with a stapes clip coupler. Speech discrimination scores in both quiet and noise environments showed better functional gain with the VSB than with the use of a conventional hearing aid. The results of the present case show the feasibility of implanting a VSB with a stapes coupler in patients with mixed hearing loss due to chronic otitis media.

Cholesterol granulomas are benign granulomatous lesions caused by tissue reaction to a foreign body such as cholesterol crystals. These crystals have been are associated with pathological conditions of pneumatized spaces, including those causing inadequate aeration, obstruction of drainage, and hemorrhage in pneumatized spaces, and where materials trapping materials, such as hemosiderin or cholesterol become trapped, and then forming a cholesterol granuloma. Cholesterol granulomas are frequently found in the temporal bones, with the middle ear, mastoid caverna, and petrous apex being the most commonly affected sites. As there have been few reported cases of cholesterol granulomas presenting as a mass in the external acoustic canal (EAC), a cholesterol granuloma occluding the entire EAC in a pediatric patient is considered quite rare. We encountered a large cholesterol granuloma occupying the entire EAC, resulting in total EAC occlusion in a 12-year-old girl. The granuloma was diagnosed via medical imaging and surgically excised.

Congenital Cholesteatoma Localized to the Tip of the Mastoid Bone: A Case Report and Possible Etiology.

Seok Min HONG ; Jun Ho LEE ; Chan Hum PARK ; Hyung Jong KIM

Korean Journal of Audiology.2014;18(2):85-88. doi:10.7874/kja.2014.18.2.85

Congenital cholesteatomas of mastoid origin are extremely rare. We reported one in 2007 and experienced an additional case. A male presented with a 5-month history of right-sided ear discharge. Computed tomography of the temporal bone showed a soft tissue density occupying the mastoid tip. At surgery, the cholesteatoma sac was completely isolated from the mastoid antrum and lateral air cell in the mastoid tip area. We now doubt the rarity of this entity. With a brief literature review, we consider how the cholesteatoma localizes to the tip of the mastoid bone.

Min Joon PARK ; Sung Won YOON ; Kang Hyeon KIM ; Young Jin KIM

Korean Journal of Audiology.2014;18(2):80-84. doi:10.7874/kja.2014.18.2.80

A speech discrimination test is a test using a list of 25 phonetically balanced monosyllables. It is often overlooked but significant enough for pure tone audiometry. Many physicians have performed pure tone audiometry but without a speech discrimination test. A 73-year-old woman visited our clinic complaining of sudden bilateral hearing loss. Pure tone audiometry showed only bilateral high frequency loss. However, speech discrimination had decreased markedly. We decided to follow-up after 1 week of Ginexin-F(R) (ginkgo leaf extract) and Nafril(R) (nafronyl oxalate). She felt a gait disturbance within 2 days. Magnetic resonance imaging revealed a left thalamic hemorrhage. After a 1 month hospitalization, the hematoma subsided, and speech discrimination recovered 3 months later. Acute hearing loss due to thalamic hemorrhage that recovered has never been reported. We report the first case of retrocochlear hearing loss that occurred with a thalamic hemorrhage in a patient who recovered.

Korean Journal of Audiology.2014;18(2):76-79. doi:10.7874/kja.2014.18.2.76

Acute or chronic otitis media can cause intracranial complications, one of the most serious being brain abscess. Empirical antibiotic treatment and proper surgical management should be considered to avoid fatal consequences. However, proper extent and optimal timing of surgical intervention are still matters of debate. We present a case of a 31-year-old man who presented with acutely altered mental status, caused by otogenic brain abscess who we treated successfully with antibiotics and otologic surgery and no neurosurgical treatment.

Korean Journal of Audiology.2014;18(2):69-75. doi:10.7874/kja.2014.18.2.69

BACKGROUND AND OBJECTIVES: High-dose systemic steroid therapy is the mainstay treatment for sudden sensorineural hearing loss (SSNHL). Recovery rates from SSNHL range are about 47-63% and are influenced by various prognostic factors. To evaluate the prognostic value of specific clinical parameters, we reviewed 289 cases by clinical and statistical analysis. SUBJECTS AND METHODS: This study included 289 patients with SSNHL who visited the Department of Otolaryngology at Soonchunhyang University Hospital from January 2005 to December 2012. The cases were reviewed retrospectively based on clinical charts. Hearing improvement was evaluated in relation to pure-tone audiogram results, duration between SSNHL onset and time of initial treatment, seasonal incidence, dizziness, patient age, degree of hearing loss, patterns of initial pure-tone audiogram and presence of underlying disease. RESULTS: Hearing improvement was observed in 196 of 289 (67.8%) patients; such improvement began within 7 days in most patients, followed by rapid hearing recovery. Cases that failed to show improvement within 14 days were unlikely to achieve hearing recovery. The more severe the hearing loss during the early stage, the lower the hearing recovery rates. Patients aged less than 60 years appear to have better prognosis of hearing improvement compared to those who are over 60 years. CONCLUSIONS: Important prognostic factors for recovery in patients with SSNHL include the time of initiating treatment after symptom onset, the degree of early-stage hearing loss, and the age of the affected patient.

Korean Journal of Audiology.2014;18(2):58-68. doi:10.7874/kja.2014.18.2.58

BACKGROUND AND OBJECTIVES: To compare the effectiveness of monitoring cisplatin-induced ototoxicity in adult patients using extended high-frequency pure-tone audiometry (EHF-PTA) or distortion-product otoacoustic emission (DP-OAE) and to evaluate the concurrence of ototoxicity and nephrotoxicity in cisplatin-treated patients. SUBJECTS AND METHODS: EHF-PTA was measured at frequencies of 0.25, 0.5, 1, 2, 3, 4, 6, 8, 9, 11.2, 12.5, 14, 16, 18, and 20 kHz and DP-OAE at frequencies of 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, and 8 kHz in cisplatin-treated patients (n=10). Baseline evaluations were made immediately before chemotherapy and additional tests were performed before each of six cycles of cisplatin treatment. Laboratory tests to monitor nephrotoxicity were included before every cycle of chemotherapy. RESULTS: Four of 10 patients showed threshold changes on EHF-PTA. Five of 10 patients showed reductions in DP-OAE, but one was a false-positive result. The results of EHF-PTA and DP-OAE were consistent in two patients. Only one patient displayed nephrotoxicity on laboratory tests after the third cycle. CONCLUSIONS: In our study, the incidence rate of cisplatin-induced ototoxicity was 40% with EHF-PTA or DP-OAE. Although both EHF-PTA and DP-OAE showed the same sensitivity in detecting ototoxicity, they did not produce the same results in all patients. These two hearing tests could be used to complement one another. Clinicians should use both tests simultaneously in every cycle of chemotherapy to ensure the detection of ototoxicity.

Myung Hoon YOO ; Byung Chul KANG ; Hong Ju PARK ; Tae Hyun YOON

Korean Journal of Audiology.2014;18(2):54-57. doi:10.7874/kja.2014.18.2.54

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate surgical interventions and hearing rehabilitation in patients with chronic middle ear disease of only hearing ears. SUBJECTS AND METHODS: Thirty-one patients with chronic middle ear disease of only hearing ears were enrolled in this retrospective study. Patients were classified into three groups according to the hearing level: groups A [pure tone audiometry (PTA)<40], B (40< or =PTA<70), and C (PTA> or =70). We evaluated hearing results and patterns of auditory rehabilitation. RESULTS: The main consideration for a surgical procedure was the presence of recurrent otorrhea and structural destruction. The reasons for surgical intervention in only hearing ears were otorrhea caused by chronic otitis media (68%), cholesteatoma (29%), and cholesterol granuloma (3%). The causes of contralateral deaf ears were chronic otitis media (81%) and sensorineural hearing loss (19%). Although there was hearing deterioration in some patients with severe hearing loss (PTA> or =70), all patients achieved dry ears after surgery and functional hearing using auditory rehabilitation. Hearing aids were used in most patients with moderate to moderately severe hearing loss and cochlear implants were used for auditory rehabilitation in patients with severe to profound hearing loss. CONCLUSIONS: Proper evaluation and indications for surgery in only hearing ears are important for successful eradication of inflammation and hearing preservation. Surgical interventions can achieve dry ear and enable further auditory rehabilitations using hearing aids and cochlear implantation.

Niloufar RASTEGARIANZADEH ; Mohammadrahim SHAHBODAGHI ; Soghrat FAGHIHZADEH

Korean Journal of Audiology.2014;18(2):50-53. doi:10.7874/kja.2014.18.2.50

BACKGROUND AND OBJECTIVES: The primary purpose of this study was to assess whether very early access to speech sounds provided by the cochlear implant enables children to develop age-appropriate phonological awareness abilities in their preschool and school years. A secondary purpose of this study was to examine whether children who had cochlear implantation before 18 months of age will develop better skills in phonological awareness than children who had cochlear implants in 18-36 months of age. A third purpose of this study was to examine whether some factors like the child's age or sex would have any effects on developing of age-appropriate phonological awareness abilities. SUBJECTS AND METHODS: 48 children with 70 to 95 months of age who had been utilizing their cochlear implant(s) before 36 months of age (CI group) and 30 normal hearing peers (NH group) were enrolled in this study. RESULTS: Child's age had a significant effect on phonological awareness, but sex had absolutely no effect in each group. Children in the cochlear implanted group were outperformed by their normal hearing peers in the area of phonological awareness, especially in phonemic awareness. The age of implantation was another significant variable. CONCLUSIONS: Although children with a younger age at implantation got better scores in phonological awareness test, they were outperformed by their normal hearing peers in this area.

Strategy for the Customized Mass Screening of Genetic Sensorineural Hearing Loss in Koreans.

Mun Young CHANG ; Byung Yoon CHOI

Korean Journal of Audiology.2014;18(2):45-49. doi:10.7874/kja.2014.18.2.45

Hearing loss is one of the most common sensorineural disorder. More than half of congenital bilateral profound deafness cases have been estimated to be attributed to genetic cause. Identification of genetic cause can provide valuable information. We developed new diagnostic strategy combining phenotype-driven candidate gene approach and targeted exome sequencing to find out the causative mutation of hearing loss. The causative mutation detection rates of this strategy were 78.1% and 54.8% in Korean multiplex families and sporadic severe to profound hearing loss families, respectively. The most frequent causative genes of Korean multiplex families were SLC26A4 and POU3F4. The other causative genes were MRNR1, WFS1, COCH, TECTA, MYO6, COL11A2, EYA4, GJB3, OTOF, STRC, MYO3A, and GJB2. The most frequent causative gene of Korean sporadic severe to profound hearing loss families was SLC26A4 followed by GJB2, CHD7, and CDH23. Based upon the results, the value of this strategy as a diagnostic tool seems to be promising. Although whole genome and exome sequencing have advanced as the development of next-generation sequencing, this new strategy could be a good screening and diagnostic tool to find the causative mutations.
