ABSTRACT

OBJECTIVE: This study evaluated gender differences in the relationship between psychiatric distress and subjective tinnitus severity. METHODS: This cross-sectional study included 134 female and 114 male patients who visited the otology outpatient clinic at Seoul St. Mary’s Hospital for tinnitus from February to July 2015. Patients completed a series of instruments, including the Tinnitus Handicap Inventory, Beck Depression Inventory, Korean version of Brief Encounter Psychosocial Instrument (BEPSI-K), and visual analogue scales assessing various tinnitus characteristics (loudness, awareness, annoyance, and effect on life). RESULTS: Tinnitus severity did not significantly differ between the gender groups (p=0.632), and it correlated significantly with tinnitus characteristics and psychiatric distress. Partial correlations between tinnitus severity and depressive symptoms were stronger in males (r=0.411, p<0.01) than in females (r=0.304, p<0.01) while controlling for duration of tinnitus and tinnitus characteristics. However, stress (BEPSI-K) was positively correlated with tinnitus severity in only males (r=0.463, p<0.01). A multiple regression analysis revealed that effect of tinnitus on life, depressive symptoms, and stress were significantly associated with tinnitus severity in males, whereas only tinnitus annoyance and depressive symptoms were associated with tinnitus severity in females. CONCLUSION: Tinnitus severity was significantly correlated with depressive symptoms and stress, and there were gender differences in the relationship between tinnitus severity and psychiatric components. It is necessary to be vigilant of psychiatric symptoms among patients with tinnitus who visit the otology outpatient clinic, especially for male patients.

ABSTRACT

BACKGROUND AND OBJECTIVES: Qualitative and quantitative data of tinnitus are both important to obtain necessary information for assessing tinnitus evaluation. But contrary to quantitative questionnaire, qualitative data is not standardized in Korea. This study aimed to standardize the qualitative data of tinnitus by developing a Korean-type integrated qualitative tinnitus questionnaires. SUBJECTS AND METHOD: A cross-sectional survey of Korean otolaryngologists was performed. The questionnaires were administered to otologists who were registered as participants in the tinnitus study group of otology research interest group (ORIG). RESULTS: Most of the otologists (100% of responders) have used the quantitative tinnitus questionnaire measurement (90.5%), but only 76% have used qualitative tinnitus questionnaire. From the responses of otologists who regularly use qualitative questionnaire, 25 items were adopted from the 35 item list. Questionnaire items were selected according to the frequency of listed items in the individual lists. CONCLUSION: We made a qualitative questionnaire consisting of 25 items that were essential and widely accepted. We expect this work will integrate and standardize qualitative tinnitus questionnaires in Korea.

ABSTRACT

OBJECTIVES: The aim of this multicenter registry study was to investigate the effectiveness of ventilation tube insertion and the microbiology of otitis media with effusion (OME) in children. This part I study was conducted to evaluate the microbiological profile of children with OME who needed ventilation tube insertion. METHODS: Patients < 15 years old who were diagnosed as having OME and received ventilation tube insertion were prospectively enrolled in 16 tertiary hospitals from June 2014 to December 2016. After excluding patients with missing data, the data of 397 patients were analyzed among a total of 433 enrolled patients. The clinical symptoms, findings of the tympanic membrane, hearing level, and microbiological findings were collected. RESULTS: In 103 patients (25.9%), antibiotics were used within 3 weeks before surgery. Ventilation tube insertion was performed in a total of 710 ears (626 in both ears in 313 patients, 55 in the left ear only, and 29 in the right ear only). Culture of middle ear effusion was done in at least one ear in 221 patients (55.7%), and in a total of 346 ears. Only 46 ears (13.3%) showed positive results in middle ear effusion culture. Haemophilus influenzae (17.3%, followed by coagulase-negative Staphylococcus and Staphylococcus auricularis) was the most common bacteria detected. CONCLUSION: H. influenzae was the most commonly found bacteria in middle ear effusion. Relatively low rates of culture positivity were noted in middle ear effusion of patients with OME in Korea.

ABSTRACT

OBJECTIVES: The classical overlay tympanoplasty is technically difficult with some disadvantages and thus less popular. However, it is particularly useful for large, anterior perforations. In this study, we describe the technique of a modified overlay graft in the tympanoplasty coined as the swing-door overlay tympanoplasty and report its outcomes. METHODS: Retrospective review of patients undergoing the swing-door overlay tympanoplasty at a tertiary referral center between 2003 and 2016 was performed. Patient who had ossicular abnormality, previous tympanoplasty, and profound hearing loss were excluded. The surgical technique is described in detail. The outcomes were evaluated by the graft success rate, complication rate, and hearing results. The hearing level was determined by four pure-tone average at 0.5, 1, 2, and 4 kHz. Air-bone gap closure was mainly assessed. RESULTS: A total of 306 patients (110 males and 196 females) were included. The mean age was 49.1±16.6 years. Follow-up periods ranged from 6 to 108 months with an average of 18.4 months. The overall graft success rate reached 98.4%. Five graft failures occurred with reperforation in three cases and lateralization in two cases. Postoperative complications occurred in 12 cases (3.9%). Air-bone gap changes (closures) were 7.8±12.8, 5.2±12.2, 5.7±10.2, and 6.0± 12.8 dB at 0.5, 1, 2, and 4 kHz, respectively (all P < 0.001) with an average improvement of 6.2 dB. Postoperative airbone gap was closed to ≤20 dB in 86.9%. CONCLUSION: The swing-door overlay tympanoplasty is a highly successful surgical technique suitable for all types of tympanic membrane perforations. This approach is technically easier than classical overlay tympanoplasty and affords an excellent graft success rate with satisfying hearing results.

ABSTRACT

BACKGROUND AND OBJECTIVES: Tinnitus retraining therapy (TRT) is one of the most effective treatment modalities of tinnitus based on the neurophysiological model proposed by Jastreboff and Hazell. This study was performed to evaluate the effect of counselor factor on treatment outcomes of TRT. SUBJECTS AND METHOD: The total of 78 patients who had TRT from three different counselors in a tinnitus clinic of tertiary referral center from Jan 2015 to Dec 2015 were included in this study. Their medical records were retrospectively reviewed to evaluate the therapeutic response to TRT. RESULTS: Among 78 patients who were followed-up for more than 6 months, 47, 20, and 11 patients were treated by counselors A, B, C (all ENT specialists), respectively. Counselor A had 15-year-experience of TRT counseling, whereas counselor B and C were well trained but beginners of TRT counseling. Initial clinical characteristics including Tinnitus Handicap Inventory (THI) and tinnitus Visual Analogue Scale (VAS) scores of the patients among three groups were not significantly different. Treatment responses evaluated via THI and most of the tinnitus VAS scores after at least 6 months after TRT were significantly improved in all three groups (p<0.05) with no significant difference between the senior (A) and junior (B, C) group. CONCLUSION: TRT seems to be an effective treatment modality of tinnitus even in this short term follow-up study. Treatment outcomes of TRT may not depend on the counselors once they are well trained and follow the same protocol.

ABSTRACT

OBJECTIVES: Baso-apical gradients exist in various cochlear structures including medial olivocochlear (MOC) efferent system. This study investigated the cochlear regional differentials in the function and morphology of the MOC system, and addressed the functional implications of regional MOC efferent terminals (ETs) in the mouse cochlea. METHODS: In CBA/J mice, MOC reflex (MOCR) was assessed based on the distortion product otoacoustic emission in the absence and presence of contralateral acoustic stimulation. High, middle, and low frequencies were grouped according to a mouse place-frequency map. Cochlear whole mounts were immunostained for ETs with anti-α-synuclein and examined using confocal laser scanning microscopy. The diameters of ETs and the number of ETs per outer hair cell were measured from the z-stack images of the basal, middle and apical regions, respectively. RESULTS: The middle cochlear region expressed large, clustered MOC ETs with strong MOCR, the base expressed small, less clustered ETs with strong MOCR, and the apex expressed large, but less clustered ETs with weak MOCR. CONCLUSION: The mouse cochlea demonstrated regional differentials in the function and morphology of the MOC system. Strong MOCR along with superior MOC morphology in the middle region may contribute to ‘signal detection in noise,’ the primary efferent function, in the best hearing frequencies. Strong MOCR in spite of inferior MOC morphology in the base may reflect the importance of ‘protection from noise trauma’ in the high frequencies.

ABSTRACT

BACKGROUND AND OBJECTIVES: This study investigated the surgical and rehabilitative results of cochlear implantation combined with subtotal petrosectomy in patients with chronic otitis media. SUBJECTS AND METHOD: We retrospectively reviewed the medical records of nine adult patients (7 men and 2 woman; mean age 58.9 years), who were operated between 2004 and 2014. Out of the nine, seven patients received simultaneous cochlear implantation and subtotal petrosectomy and two patients were operated by stage depending on the condition of the middle ear. All cases underwent closure of the external auditory canal and Eustachian tube, and the obliteration of mastoid cavity using abdominal fat. Surgical outcomes and performance of the patients after cochlear implantation were analyzed. RESULTS: Middle ear inflammation was completely managed with this surgical technique. No patients showed postoperative symptoms related to otitis media after the surgery. Cochlear implant was successfully replaced and active electrodes were fully inserted in all of the cases. There were no immediate complications including abscess, infection, meningitis, cerebrospinal fluid leakage and ear canal problem. One patient was observed with delayed extrusion of the ball electrode, which was replaced with cartilage reinforcement under local anesthesia. Patient performance, measured in terms of speech evaluation and quality of life during the medical interview, were successful and satisfactory. CONCLUSION: Cochlear implantation with subtotal petrosectomy seems to be very safe and effective for patients deafened by chronic otitis media. Long term follow-ups for possible extrusion of the electrode or other complications are still necessary.

ABSTRACT

Objective tinnitus originates from the para-auditory structures of the head and neck and can be heard or documented by examiner. Three representative forms of objective tinnitus, according to the causal organs are myoclonic tinnitus, vascular tinnitus and tinnitus caused by the patulous Eustachian tube. Etiologies, pathologic mechanisms, diagnostic approaches, and proper treatment methods of objective tinnitus are comprehensively discussed with a review of literatures. Objective tinnitus can be cured in many cases. Clinicians need to be well aware of the clinical characteristics of objective tinnitus since early, correct diagnosis with proper management are mandatory for its cure.

ABSTRACT

BACKGROUND AND OBJECTIVES: Hearing loss has been hypothesized to contribute to cognitive decline in the elderly. However, earlier studies yielded conflicting results, and the causal relationship has not been elucidated to date. In the present study, the authors set up a radial maze apparatus for assessment of cognition in mice, and investigated the relationship between cognition and hearing loss that occur immediately after noise exposure. MATERIALS AND METHOD: Spatial learning and memory were assessed in male C57BL/6 mice with or without hearing loss using an unconfined, partially-baited, 8-arm radial maze with different arm length (25 or 50 cm). The performance indicators included total trial time, latency, reference memory error, working memory error, and correct entry ratio. Mice in the hearing loss group were exposed to 60 min of 110 dB white noise for 14 days, and then auditory brainstem response thresholds were measured. RESULTS: Mice showed better performances in a 25 cm-arm radial maze than in a 50 cm-arm maze. The control and the hearing loss groups exhibited similar performance curves, except for the working memory curve in 25 cm-arm radial maze. Hearing-impaired mice were better at working memory tasks than the control mice, probably due to an early cognitive compensatory mechanism. CONCLUSION: A radial maze with 25 cm arm is appropriate for the test of learning and memory in mice. Acute hearing loss after noise exposure was not associated with decreased cognition. Further follow-up research has been planned to find the effect of long-term hearing loss on cognition and the mechanism by which these two domains are connected.

ABSTRACT

OBJECTIVES: Vascular tinnitus is the most common form of pulsatile tinnitus, particularly when the tinnitus corresponds with the pulse of patients. In this study, we reviewed the 10-year clinical data on vascular tinnitus of our tinnitus clinic to investigate the frequency of the underlying etiologies, to introduce a diagnostic protocol, and to evaluate the treatment outcomes. METHODS: We retrospectively collected the data of 57 patients who were diagnosed as vascular tinnitus between April 2001 and December 2011. Careful history taking, otoscopy, thorough physical examinations, audiometry, laboratory tests, as well as radiologic examinations were performed according to our diagnostic protocol to find the origin of pulsatile tinnitus. Treatment options were individualized based on the specific etiology, and the outcomes were assessed using patient's subjective reports at the follow-up interviews. RESULTS: High jugular bulb was the most common cause (47.4%) of vascular tinnitus, and venous hum was the next (17.5%). Dural arteriovenous fistula, intracranial aneurysm, atherosclerotic carotid artery disease, and hypertension were less common causes. Vascular tinnitus was alleviated in most patients after the appropriate treatment: surgical intervention, tinnitus retraining therapy, reassurance, and medications. CONCLUSION: Vascular tinnitus can be successfully diagnosed by the regular use of the suggested protocol. Many patients with vascular tinnitus have treatable underlying etiologies. Treatment of those etiologies or at least counseling about the tinnitus itself can benefit the patients with troublesome vascular tinnitus.

ABSTRACT

BACKGROUND AND OBJECTIVES: The effective management of tinnitus should start with an accurate diagnosis, but no concensus has been developed in Korea concerning how to measure the features of tinnitus. This study surveyed otologists in the training hospitals and hospitals specialized in otologic care in Korea to identify the current status in the assessment of patients with tinnitus. SUBJECTS AND METHOD: The questionnaire on the assessment of tinnitus was sent by email to otologists in training and to specialized hospitals specializing in otologics in Korea. The questionnaire included inquiry about various types of tests conducted, such as the audiologic test, tinnitus test, blood test, radiologic test, and the methods of history taking and physical examination for somatic tinnitus. RESULTS: Regarding the audiologic assessment of tinnitus, all the otologist were using pure tone audiometry, 97% speech audiometry, and 87% tinnitus test. For the psychophysical measure of tinnitus, both loudness and pitch matching were conducted by all the otologists. The performance rate of blood test were 38.5%, and the most preferred radiologic test in pulsatile tinnitus was temporal bone computed tomography (59%). Finally, the rate of investigation including the history taking and physical examination of somatic tinnitus was between 74-84%. CONCLUSION: Our results showed that although the tests perfermed by otologists varied, the essential tests for assessing tinnitus were commonly practiced. We analyzed the current status of tinnitus assessment and supplemented guidlines to help measure tinnitus. Further concensus on tinnitus diagnosis is needed, particularly about the standadized and unified principles.

ABSTRACT

Herniation of the temporomandibular joint (TMJ) into the external auditory canal (EAC) is known to be associated with a defect of the anterior wall of the EAC. Spontaneous herniation of TMJ into EAC is very rare and can induce clicking tinnitus, conductive hearing loss, otalgia, otorrhea and even no symptom. Here we report a very interesting case of spontaneous TMJ herniation, which resulted in severe and annoying clicky tinnitus and otalgia. There was no response to the initial conservative management, so surgical correction of TMJ herniation using titanium mesh was performed. After the surgery, the annoying clicky tinnitus completely disappeared. This study suggests that tinnitus caused by TMJ herniation be considered as another type of surgically curable objective tinnitus.

ABSTRACT

Patulous Eustachian tube is a benign, but bothersome condition, which can cause severe physical and psychological problems. We investigated the clinical features and the therapeutic result of the surgery in three patients, whose patulous Eustachian tube symptom were treated by the surgical insertion of a specially designed, tripod-tipped-bone wax-filled angiocatheter into the bony orifice of the Eustachian tube. Immediate disappearance of the troublesome symptoms was observed in all six patients. No serious complications were observed during the follow-up period. Factors considered for this surgical therapy and the method of designing our specific angiocatheter are introduced in detail. Surgical therapy for patients with serious patulous Eustachian tube symptoms by inserting the tripod-tipped-bone wax-filled angiocatheter seemed promising. Further studies on its long-term therapeutic effects might be necessary using a large number of the patients.

ABSTRACT

Cartilaginous choristoma of bony external auditory canal is very rare. Appearing as a horny sha-ped hard mass, cartilaginous choristoma can be found in the medial portion of anterior wall of external auditory canal. Histologically, it consists of adult-type hyaline cartilage without neoplastic features. If cartilaginous choristoma shows growing tendency or ear symptoms, surgical excision would be the treatment of choice. Here, we report a case of cartilaginous choristoma that occurred in the external auditory canal in an 8-year-old boy.

ABSTRACT

BACKGROUND AND OBJECTIVES: The effective management of subjective tinnitus should start with an accurate diagnosis based on an appropriate classification. Since there is no gold standard for managing subjective tinnitus, clinicians can select from various treatment options after considering the multifactorial etiology of tinnitus. This study surveyed otologists at university hospitals in Korea to identify the treatments used for subjective tinnitus and to obtain basic information on evidence-based medicine for treating tinnitus. SUBJECTS AND METHOD: A five-major-item questionnaire on current tinnitus treatments was sent by email to otologists at 37 university hospitals in Korea; 30 (81.1%) replied. RESULTS: The mean incidence of tinnitus in otology outpatient clinics was 22.7% (range 10-40%). Common treatments were oral pharmacological therapy, regular counseling with tinnitus retraining or cognitive behavioral therapy and hearing aids. Tinnitus retraining therapy and hearing aids were considered the most effective when the visual analog scale scores were 7.0 and 6.6, respectively, and considered safe when the scores were 9.9 and 9.3. Ginkgo biloba and benzodiazepines were the most frequently prescribed drugs, although their reported effectiveness was questionable. Intra-tympanic steroid injection was not considered effective (3.8) or safe (6.3). Somatosensory-based treatments such as treating neck muscle or temporomandibular joint disorders were also used to relieve a subgroup of somatic tinnitus. CONCLUSION: Our results showed trends similar to those in other countries, yet we have not reached the level of evidence-based clinical practice due to the lack of reliable and effective treatment options. Further research on tinnitus-treatments is needed, particularly about randomized controlled studies with blinding.

ABSTRACT

OBJECTIVES: The authors have treated chronic tinnitus patients using a combination of a simplified tinnitus retraining therapy (TRT) and medications, which we called modified TRT. In this clinical setting, we have attempted small-group counseling to find a time-effective equivalent of individual counseling. The aim of the present study was to evaluate the effectiveness of small-group counseling by comparing the treatment outcomes between individual and small-group counseling. METHODS: The patients who had distressing chronic tinnitus with normal hearing or mild hearing loss were included. The subjects were placed into the small-group (group 1:4) or the individual (group 1:1) counseling group, and underwent a modified TRT composed of a single session of directive counseling and ambient sound stimulation. In addition, alprazolam (0.25 mg) and ginkgo biloba extract (80 mg) were administered orally to the subjects for 3 months. The 3- and 6- month outcomes were assessed using the follow-up rates and tinnitus severity scores: awareness, tinnitus handicap inventory (THI), loudness, annoyance, and effect on life. The treatment responses were classified as improvement, no changes, and worsening. RESULTS: Of the total 149 patients (77 in group 1:1; 72 in group 1:4), 104 patients completed the protocol at 3 months, and 55 patients at 6 months. The follow-up rates were similar in both groups. Over the period of 6 months, all scores declined significantly except the loudness score at 3 months in both groups. Treatment responses showed no between-group differences. The success rate based on THI was 70% in group 1:1, and 64% in group 1:4 at 6 months. CONCLUSION: The small-group counseling of our modified TRT was comparable to the individual counseling for tinnitus relief. We suggest that this protocol can be implemented effectively in any crowded otolaryngology clinics.

ABSTRACT

BACKGROUND AND OBJECTIVES: It is necessary to establish the most efficient diagnostic and therapeutic method for benign paroxysmal positional vertigo (BPPV), which is appropriate for Korean healthcare system. We aimed to evaluate current state of Korean clinician's diagnostic and therapeutic approaches for BPPV. MATERIALS AND METHODS: A 16-item survey was emailed to the members of dizziness department of Otology Research Interest Group in the Korean Otologic Society (n=68). 43 were returned and analyzed. RESULTS: All respondents (100%) used Dix-Hallpike test as a diagnostic tool for vertical canal-BPPV. Supine roll test was used for diagnosing lateral canal BPPV in nearly all the respondents (97.7%). Epley maneuver was chosen as otolith repositioning maneuver (ORM) for posterior canal BPPV in all respondents and barbecue rotation (BBQ) was used for treating lateral canal BPPV with geotropic nystagmus in 95.3% of respondents. Extreme variation was noted for therapeutic approach of lateral canal BPPV with ageotropic nystagmus BBQ, with 4 kinds of ORM and adjunctive measures to liberate otolith from cupula, while BBQ was again the most commonly used ORM (76.7%). CONCLUSION: The development of practical and efficient ORM for lateral canal BPPV with ageotropic nystagmus is necessary.

ABSTRACT

The parotid gland salivary fistula is one of the complications following parotidectomy and can result in patient discomfort and wound infection. Various methods have been used for resolution of salivary gland fistula including non surgical and surgical management. Non-surgical managements such as pressure dressing, radiation therapy and pharmacotherapy are simple and safe but mostly require a relatively long period for healing. Surgical managements are recommended if conservative therapy and pharmacological intervention fail. Surgical options for parotid gland salivary fistula include total parotidectomy, salivary duct ligation, delayed primary repair of duct, and tympanic neurectomy. However, there is no uniform consensus regarding the surgical option of choice for parotid gland salivary fistula. Recently, we experienced a patient with a persistent parotid gland salivary fistula after parotidectomy, which was successfully treated by tympanic neurectomy. We found that the effect of tympanic neurectomy was not strong enough to be recommended as a method of choice for the clinical inactivation of persistent parotid gland salivary fistula. Therefore, we report this case for the first time in our country with the review of literatures.

ABSTRACT

BACKGROUND AND OBJECTIVES: The evaluation of subjective outcomes of hearing aid fitting is of paramount importance along with audiometric improvement. The aim of this study was to develop a Korean adaptation of the International Outcome Inventory for Hearing Aids (IOI-HA) and to determine its reliability and validity. SUBJECTS AND METHOD: The translation of IOI-HA into the Korean version (K-IOI-HA) was completed through a process of forward translation, reconciliation, reverse translation and cognitive debriefing. K-IOI-HA was administered to 101 patients using hearing aids and visiting any the 10 referral hospitals. Reliability was evaluated by Cronbach's alpha coefficient and by test-retest analysis. Validity was assessed by confirmatory factor analysis and criterion validity based on the results of pure tone audiometry. RESULTS: K-IOI-HA showed a good internal consistency (Cronbach's alpha=0.83) and a high test-retest reliability (r=0.943, p<0.01). Validity checked by confirmatory factor analysis also showed good construct validity. CONCLUSION: The Korean version of IOI-HA is a reliable and valid tool for evaluating subjective outcomes of hearing aids.

ABSTRACT

Acute otitis media (AOM) and otitis media with effusion (OME) are common infections in children, and their diagnosis and treatment have significant impacts on the health of children and the costs of providing national medical care. In 2009, the Korean Otologic Society organized a committee composed of experts in the field of otolaryngology, pediatrics, and family medicine to develop Korean clinical practice guidelines (CPG) for otitis media in children with the goal of meeting regional medical and social needs in Korea. For this purpose, the committee adapted existing guidelines. A comprehensive literature review was carried out primarily from 2004 to 2009 using medical search engines including data from Korea. A draft was written after a national questionnaire survey and several public audits, and it was editorially supervised by senior advisors before publication of the final report. These evidence-based guidelines for the management of otitis media in children provide recommendations to primary practitioners for the diagnosis and treatment of children younger than 15 yr old with uncomplicated AOM and OME. The guidelines include recommendations regarding diagnosis, treatment options, prevention and parent education, medical records, referral, and complementary/alternative medicine for treating pediatric otitis media.
