RESUMO
In mid-2022, as the wave of pediatric coronavirus disease 2019 (COVID-19) cases escalated in South Korea, a public-private partnership was made to establish a Pediatric COVID-19 Module Clinic (PMC). We describe the utilization of the first prototype children’s modular clinic in Korea University Anam Hospital functioning as the COVID-19 PMC. Between August 1 and September 30, 2022, a total of 766 children visited COVID-19 PMC. Daily number of patient visits to the COVID-19 PMC ranged between 10 and 47 in August; and less than 13 patients per day in September 2022. Not only the model provided timely care for the COVID-19 pediatric patients, but it also enabled safe and efficacious care for the non-COVID-19 patients in the main hospital building while minimizing exposure risk to severe acute respiratory syndrome coronavirus 2 transmission. Current description highlights the importance of spatial measures for mitigating in-hospital transmission of COVID-19, in specifically on pediatric care.
RESUMO
Background@#The aims of this study are to review data on 4-months age National Health Screening Program for Infants and Children (NHSPIC) using a National Health Insurance Service (NHIS) database, and to analyze the newborn hearing screening (NHS) results and related characteristics of the 4-months NHSPIC for 7 years in South Korea. @*Methods@#We analyzed a NHIS database of infants who had participated in the 4-month age NHSPIC from 2010 to 2016. According to the results of hearing questionnaires and physical examination, we analyzed the outcomes of NHS and related infantile and socioeconomic factors. @*Results@#Among 3,128,924 of total eligible infants in Korea between the year 2010 and 2016, 69.2% (2,164,621 infants) conducted 4-months age NHSPIC, and 94.4% (2,042,577 infants) of which performed hearing questionnaires regarding NHS. Among the total hearing examinees, premature infants accounted for 3.6%, infants who were hospitalized in the neonatal intensive care unit (NICU) for more than 5 days accounted for 5.6%, and infants with head and neck abnormalities were 0.6%. The NHS performing rate was 79.1% for total hearing examinees in 2010, but gradually increased to 88.9% in 2016. The NHS performing rate in 2016 was 93.4% for premature infants, 91.7% for NICU hospitalized babies. The mean referral rate was 0.6% for total hearing examinees, 1.4% for premature infants, and 2.3% for NICU hospitalized babies. When we analyzed the NHS performing rate and the referral rate according to the household income level, the NHS performing rate of infants in Medical Aid programs was the lowest as 65.6%, and the NHS performing rates in other five levels of NHIS was higher ranging between 85.1% to 86.0%. The referral rate of infants in the Medical Aid program (3.8%) was significantly higher than those of infants in other classes (1.10–1.25%). @*Conclusion@#The estimated overall NHS performing rate in Korea gradually increased and was 88.9% in 2016. The overall referral rate was low as 0.6%, and it was significantly different depending on the infant’s health condition and household income levels. We assume that our finding would help to establish policies managing hearing impaired children, and to develop the customized hearing care service programs considering the household economic levels.
RESUMO
Background and Objectives@#To analyze mapping changes in dynamic range (DR) and neural response threshold (NRT) as prognostic factors for cochlear implant (CI). To analyze whether postoperative speech perception performance could be predicted using DR change and initial NRT. @*Subjects and Methods@#The speech comprehension data of 33 patients with CI were retrospectively analyzed after 1, 3, 6, and 12 months of device use. All subjects were adult, postlingually hearing-impaired, and Cochlear Nucleus CI users. Speech perception performance was evaluated using aided pure tone audiometry, consonant, vowel, one-word, two-word, and sentence tests. @*Results@#The averages of initial NRT and DR changes were 197.8±25.9 CU (104–236) and 22.2±18.4 CU (-15–79), respectively. The initial DR was 40.8±16.6 CU. The postoperative DR was 50.3±16.4 CU at 3 months, 58±12.3 CU at 6 months, and 62.9±10.4 CU at 12 months. A gradual increase of DR was observed during the first year of CI. Compared with the initial DR, significant increases in DR were observed at 3 (p<0.05), 6 (p<0.001), and 12 (p<0.001) months. Compared with initial speech performance outcomes, a significant gain in all performance outcomes was achieved at 12 months (p<0.001). @*Conclusions@#Patients with low NRT after CI surgery could initially set DR to a wider range and had better final speech perception outcomes. Conversely, patients with high NRT after CI surgery had to set up a gradual increase in DR while adjusting the T-C level, and the final speech perception outcomes were worse. DR and NRT, the main CI mapping variables, can help predict prognosis related to speech perception outcomes after CI surgery. In conclusion, the post-CI speech perception is better with a lower initial NRT, wider final DR, or younger age.
RESUMO
Background and Objectives@#Tinnitus, although being a common chronic disease, can be an intractable disease that causes depression and insomnia. This study aimed to analyze the results of the Tinnitus Handicap Inventory (THI), Beck Depression Inventory (BDI), and Pittsburgh Sleep Quality Index (PSQI) questionnaire surveys before and after clonazepam therapy. In addition, we analyzed the association of three pre-treatment questionnaires and evaluated whether pre-treatment factors could predict the post-treatment THI index.Subjects and Method Patients were selected from those who visited a tertiary hospital from 2019 to 2021 for the treatment of chronic tinnitus they had for more than 3 months and who were over 20 years old. Patients were excluded from the study if they were diagnosed with acute sudden hearing loss, Meniere’s disease, brain/internal auditory canal tumors, or muscular/vascular tinnitus. The questionnaire surveys of THI, BDI, PSQI were conducted before and after 3 months of clonazepam therapy (Rivotril [Roche Inc.] 0.25 or 0.5 mg). Questionnaire scores were compared using the paired t-test. Multiple regression analysis was used to determine the relationships among the three questionnaires. @*Results@#A total of 76 patients (38 males and 38 females) with the mean age of 57.2±9.01 years was analyzed. The average hearing threshold was 30.4±20.67 dB HL on the right and 31.7±17.06 dB HL on the left. The pre-treatment THI, BDI, and PSQI scores were 44.3±23.4, 7.96±2.36, and 6.85±4.68, respectively. The relationships between the THI and BDI and the THI and PSQI were significant (p=0.0027 and p<0.0001, respectively). The pre-THI score showed no significant association with age, sex, or hearing threshold (p=0.91, 0.85, and 0.23, respectively). The post-treatment THI score was 33.6±17.1, which was significantly lower than the pre-THI scores (p<0.0001). Post-BDI and post-PSQI were 7.38±2.25 and 4.04±3.20, respectively. Post-PSQI also significantly decreased compared with pre-PSQI (p=0.0002), but post-BDI did not significantly decrease (p=0.1231). In the THI survey, Question 7 (sleep disturbance) showed decrease the most, followed by Question 25 (unstable mood). The post-treatment THI could be predicted by using the formula, 0.7673+0.6947×pre-THI+0.3572×pre-PSQI. @*Conclusion@#The appropriate/optional use of clonazepam at low doses (0.25-0.5 mg) can significantly improve chronic tinnitus and sleep quality. Tinnitus was significantly associated with the scores of THI, BDI, PSQI and the usage of Clonazepam significantly reduced the THI and PSQI scores. However, clonazepam did not affect the BDI score.
RESUMO
Background and Objectives@#Self-reported hearing levels determined by self-report questionnaires are not always correlated with the audiometric hearing level. It is necessary to ascertain the subjectively perceived normal hearing threshold to determine the need for hearing aids at the appropriate time. The objective is to identify the level of correlation between the self-reported hearing level and the audiometric hearing level and ascertain the subjectively perceived normal hearing threshold for each age group.Subjects and Method This cross-sectional study, using the data from the Korea National Health and Nutrition Examination Survey V, looked at participants with hearing loss who were aged ≥40 years. Pure tone audiometry was conducted bilaterally. Self-reported hearing level was ascertained via survey enquiring about hearing loss. The level of correlation between self-reported hearing level and audiometric hearing level, age-specific patterns of hear-ing self-evaluation and subjectively perceived normal hearing values at which participants complained of hearing loss were main outcomes. @*Results@#Mean audiometric thresholds (MATs) increased with the age and degree of self-reported hearing level. The accuracy of self-reported hearing level compared to the audiometric threshold decreased with age both in the better-ear and worse-ear groups. Younger participants tended to overestimate their hearing impairment, while older participants tended to underestimate it. Subjectively perceived normal hearing thresholds increased with age and they were very close to the MATs for each age group. @*Conclusion@#Results can be useful for devising different age-group specific pure tone audi-ometry-based diagnostic criteria for self-reported hearing loss, which can be used to determine the need for hearing aid in a timely manner.
RESUMO
Cognitive behavioral therapy, first introduced by Beck in the 1950s to treat depression by integrating cognitive and behavioral therapies, is now an established psychotherapy technique used to treat insomnia, chronic pain, and anxiety. Currently, cognitive behavioral therapy is widely used to treat tinnitus in European countries, and the efficacy and safety of the treatment have been proven through randomized clinical trials and meta-analyses. Although interest in cognitive behavioral therapy for tinnitus is increasing in Korea, there are limited reports. Because many studies so far have targeted patients in Western countries, it is difficult to apply the same to domestic patients due to cultural and linguistic differences, the absence of standardized guidelines, and limitations in clinic hours. We experienced various cases in which tinnitus was effectively treated simultaneously with pharmacotherapy and cognitive behavioral therapy, so here we report an introduction to the program along with a literature review. Cognitive behavioral therapy was performed as a 4-week program in our hospital, and progress was evaluated through Visual Analogue Scales (VAS) and tinnitus handicap inventory (THI). After each weekly 20-minute individual counseling session, a take-home writing task was given to the patient. The main goal was to guide the patient to discover and correct automatic thoughts related to their tinnitus symptoms. This paper aimed to introduce a specific scheme on how to perform cognitive behavioral therapy for domestic tinnitus patients.
RESUMO
Background and Objectives@#The pathogenesis of idiopathic sudden sensorineural hearing loss (ISSNHL), an otologic emergency disease, remains unclear. Several studies have attempted to illustrate the association between cytokines and ISSNHL. The purpose of this study was to evaluate the prognostic significance of various cytokines in patients with ISSNHL. Subjects and Method In this case-control study, a total of 55 patients with ISSNHL underwent treatment with oral prednisolone for 2 weeks. Serum cytokine levels, including interleukins (ILs) (IL-1a, IL-1b, IL-2, IL-4, IL-6, IL-7, IL-8, IL-10, IL-12), and tumor necrosis factors (TNF-α and TNF-β), were measured using human cytokine panels at first visit. Patient characteristics such as age, gender, the status of hypertension, diabetes mellitus, vertigo, time from onset to visit, and initial hearing levels were also evaluated. @*Results@#Serum levels of cytokines were correlated with the prognosis of ISSNHL patients. IL-4 ≥0.225 (pg/mL) and TNF-α ≥5.155 (pg/mL) were significantly associated with poor therapeutic outcomes (OR=44.317, p=0.015 and OR=269.465, p=0.006, respectively). In addition, age and initial hearing levels were also significant prognostic factors. @*Conclusion@#Patients’ age, initial hearing levels, and serum levels of IL-4 and TNF-α prior to treatment are associated with hearing recovery and can be used as prognostic factors for patients with ISSNHL.
RESUMO
Background and Objectives@#Acute low-tone hearing loss (ALHL) is gaining attention as an independent disease identity with close association with endolymphatic hydrops and early stage Meniere’s disease (MD). This study aims to compare patients of ALHL with patients exhibiting low-tone hearing loss and ear fullness without vertigo in various audio-vestibular assessments and in progression to overt MD.Subjects and Method A total of 249 patients with low-tone hearing loss with ear fullness without vertigo was enrolled in this study. Of these patients, 58 patients met criteria for ALHL, which was defined as having an average hearing loss of ≥30 dB at 125, 250, and 500 Hz and ≤20 dB at 2, 4, and 8 kHz. Demographics, electrocochleography (ECoG) abnormality, rate of hearing improvement, vestibular functions, and progression to MD were analyzed. @*Results@#An average low-tone hearing loss of ALHL patients was 42.8 dB, which recovered to 18.9 dB following a combined treatment of diuretics and oral steroid therapy. The hearing recovery rate of this group was 87.9% and the ECoG abnormality ratio was 42.5%. Also, 15.5% of ALHL patients eventually progressed to MD. @*Conclusion@#This study described demographics and characteristics of ALHL, demonstrating a successful response to the combined treatment of diuretics and oral steroid. Also, this report demonstrated a close relationship between the degree of low-tone hearing loss and ECoG abnormality and observed the progression to MD in ALHL patients. These data can be usefully applied in clinical setting to explain clinical outcomes of ALHL.
RESUMO
Objectives@#. This study aimed to investigate the relationship between tinnitus and joint pain from representative samples of Koreans. @*Methods@#. The demographics and the responses to a questionnaire about tinnitus and joint pain severity and mental health status of adults aged ≥50 years in the 2010–2012 Korean National Health and Nutrition Examination Survey were analyzed. @*Results@#. Among 9,032 individuals, 26.7% reported experiencing tinnitus within the past year. Participants with tinnitus were more frequently older, hearing loss, and had lower education levels, income, and body weight. Participants with regular exercise and sleep had a lower tinnitus prevalence. The incidences of stress, depressed mood, and suicidal ideation were significantly higher in the tinnitus group and participants with joint pain. The rates of participants with tinnitus according to the number of joint pain sites (zero, one, two, and three) was 22.1%, 31.4%, 33.3%, and 44.2%, and those of participants with severely annoying tinnitus according to the number of joint pain sites (zero, one, two, and three) were 3.3%, 6.8%, 7.9%, and 10.7%, respectively. @*Conclusion@#. Tinnitus prevalence and severity were significantly related to joint pain, and both conditions were related to psychiatric distress. Thus, the authors suggest that psychiatric distress as a common risk factor for tinnitus and joint pain should be considered when deciding treatment strategies and in guiding public health policy.
RESUMO
Background and Objectives@#Hearing loss (HL) and its repercussions are major problems in today’s society. There are limited data on the relationship between degree of HL and otologic disorders. The aim of this study is to estimate mortality rates, rates of sudden idiopathic HL and related otologic surgical procedures in hearing disability patients in South Korea. @*Subjects and Methods@#Retrospective medical data for 160,205 patients with hearing disability was extracted. Mortality rates, rates of sudden idiopathic HL and related otologic surgical procedures were compared with a normal control group consisting of 865,475 people; approximately 5 times the number of hearing disability patients. @*Results@#According to the Korean National Disability Registry (NDR), 0.458% of the population in South Korea suffered from hearing disability in 2015. Higher rates of mortality and sudden idiopathic HL were reported in hearing disability patients, increasing up to a maximum of 1.594 times and 1,039.695 times, respectively, compared to the normal control group. Mastoidectomy surgery was 2.5 times more frequently performed and pressure equalizing (PE) tube insertion was about 15 times more frequently performed in hearing disability patients. @*Conclusions@#Hearing disability is related to higher risks of mortality, sudden idiopathic HL and otologic surgical procedures, including mastoidectomy and PE tubing.
RESUMO
OBJECTIVES: The aim of this study was to analyze the incidence of inner ear anomalies in patients with unilateral congenital aural atresia (CAA) combined with microtia. METHODS: We retrospectively reviewed 61 patients with unilateral CAA combined with microtia who underwent high-resolution temporal bone computed tomography (TBCT) and hearing examination. Inner ear anomalies were analyzed using TBCT and evaluated according to the Jahrsdoerfer grading system, Marx classification, and extent of inferior displacement of the mastoid tegmen. RESULTS: Inner ear anomalies were observed in 14 patients (23.0%). Lateral semicircular canal (LSCC) dysplasia was the most common inner ear anomaly, with an incidence of 16.4%. The incidence was significantly higher on the pathologic side than on the unaffected side (P=0.002). All vascular anomalies were observed in the high-riding jugular bulb, with an incidence of 24.6%. The incidence was significantly higher on the pathologic side than on the unaffected side (P<0.001). LSCC dysplasia was significantly more common in patients with a lower Jahrsdoerfer score (odds ratio, 0.66; P=0.004). CONCLUSION: The incidence of inner ear anomalies was relatively high in patients with unilateral CAA combined with microtia; LSCC dysplasia was the most common anomaly and the probability of coexistence was higher in patients with a lower Jahrsdoerfer score.

BACKGROUND AND OBJECTIVES@#Several questionnaires had been developed to assess the handicap due to dizziness. The questionnaires for adults were used and these had been translated into Korean with validity and reliability. However, there is no Korean translation of dizziness inquiry form owing to the little concern of the pediatric dizziness. The objective of this study was to determine the reliability and validity of a Korean Dizziness Handicap Index for Patient Caregivers (KDHI-PC), and revealed the factor analysis of this index.SUBJECTS AND METHOD: We sampled the 24 pediatric patients who had dizziness-related symptoms and visited the hospitals. The patients completed a questionnaire (DHI-PC) that had been translated and reverse translated into Korean. The results of this investigation were analyzed using exploratory factor analysis, Cronbach's ñ coefficient and internal consistency reliability.@*RESULTS@#By exploratory factor analysis, KDHI-PC was divided into two scales. This questionnaire showed a good internal consistency (Cronbach's ñ=0.945). All items had good item-total correlations.@*CONCLUSION@#The KDHI-PC is a reliable tool for evaluating the dizziness of pediatric patients.
RESUMO
BACKGROUND AND OBJECTIVES@#This study aims to evaluate that usefulness of the endoscopic ear surgery (EES) through the systematic review.SUBJECTS AND METHOD: We searched literatures in literature databases (MEDLINE, EMBASE, Cochrane Library, etc.). Inclusion criteria is 1) studies of patients with chronic otitis media, otitis media with effusion, cholesteatoma, conductive hearing loss, mixed hearing loss etc. 2) studies in which a transcanal endoscopic surgery was performed; and 3) studies in which one or more of the appropriate medical outcomes have been reported. We excluded that 1) non-human studies and pre-clinical studies; 2) non-original articles, for example, non-systematic reviews; editorial, letter and opinion pieces; 3) research not published in Korean and English; and 4) grey literature. Finally, 65 articles were selected and those results were analyzed.@*RESULTS@#The safety of the EES was reported in 61 articles. Some studies reported damaged facial nerve or perilymph gusher but these are the complications that can arise due to the characteristics of the disease and not due to the EES and other reported complications were of similar or lower level in the intervention group rather than the microscopy group. The effectiveness of the EES was reported in 23 articles. The EES tended to show improved effects in terms of graft uptake status, cholesteatoma removal, and hearing improvement although effective outcomes of most studies reported no significant difference between EES and microscopic ear surgery.@*CONCLUSION@#EES is a safe and effective technique and as it is less invasive than the microscopic ear surgery.
RESUMO
BACKGROUND@#In microtia patients with bilateral hearing impairment, hearing improvement is crucial for language development and performance. External auditory canal reconstruction (EACR) has been performed to improve hearing, but often results in complications. We performed transcutaneous bone conduction implant (TBCI) surgery in these patients. This study aimed to evaluate the safety and efficacy of TBCI surgery.@*METHODS@#A retrospective review was performed of five patients who underwent auricular reconstruction and TBCI surgery and 12 patients who underwent EACR between March 2007 and August 2018. Hearing improvement was measured based on the air-bone gap values using pure-tone audiometry over a 6-week postoperative period. We reviewed other studies on hearing improvement using EACR and compared the findings with our results. The surgical techniques for TBCI were reviewed through case analyses.@*RESULTS@#Postoperative hearing outcomes showed a significant improvement, with a mean gain of 34.1 dB in the TBCI cohort and 14.1 dB in the EACR cohort. Both gains were statistically significant; however, the TBCI cohort showed much larger gains. Only three of the 12 patients who underwent EACR achieved hearing gains of more than 20 dB, which is consistent with previous studies. All patients who underwent TBCI surgery demonstrated hearing gains of more than 20 dB and experienced no device-related complications.@*CONCLUSIONS@#TBCI is a safe and effective method of promoting hearing gains in microtia patients with bilateral hearing impairment. TBCI surgery provided better hearing outcomes than EACR and could be performed along with various auricular reconstruction techniques using virgin mastoid skin.

OBJECTIVES: Nicotine has various adverse effects including negative impacts associated with maternal exposure. In the current study, we examined nicotine-induced damage of hair cells and embryotoxicity during zebrafish development. METHODS: Zebrafish embryos were exposed to nicotine at several concentrations (5, 10, 20, and 40 μM) and embryotoxicity were evaluated at 72 hours, including hatching rate, mortality, teratogenicity rate, and heart rate. Hair cells within the supraorbital (SO1 and SO2), otic (O1), and occipital (OC1) neuromasts were identified at 120 hours. Apoptosis and mitochondrial damage of hair cells were analyzed using TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling) and DASPEI (2-[4-(dimethylamino)styryl]-N-ethylpyridinium iodide) assays, respectively, and changes of ultrastructure were observed by scanning electron microscopy. RESULTS: The control group without nicotine appeared normal with overall mortality and teratogenicity rate < 5%. The hatching rate and mortality rate was not significantly different according to nicotine concentration (n=400 each). The abnormal morphology rate (n=400) increased and heart rate (n=150) decreased with increasing nicotine concentration (P < 0.05). Nicotine-induced hair cell damage significantly increased as nicotine concentration increased. A significantly greater number of TUNEL-positive cells (P < 0.01) and markedly smaller DASPEI area (P < 0.01) were shown as nicotine concentration increased. CONCLUSION: The current results suggest that nicotine induces dose-dependent hair cell toxicity in embryos by promoting apoptosis and mitochondrial and structural damage.

BACKGROUND AND OBJECTIVES: This study aims to evaluate the usefulness of customized vestibular exercise through literature review. MATERIALS AND METHOD: We searched several literature database such as Ovid-MEDLINE, Ovid-EMBASE, and Cochrane Library etc., with the following inclusion criteria: 1) studies of patients with dizziness and balance disorders, 2) studies in which a customized vestibular exercise was performed, and 3) studies in which one or more of the appropriate medical outcomes have been reported. At the same time, we excluded the following: 1) non-human studies and pre-clinical studies, 2) non-original articles, for example, non-systematic reviews, editorial, letter and opinion pieces, 3) research not published in Korean and English, 4) grey literature (thesis, congress or conference materials, abstract etc.), and 5) case studies. Finally, 10 studies were selected and analyzed. RESULTS: The safety of customized vestibular exercise was reported in three documents which reported no side effects related to the procedure. The effectiveness of customized vestibular exercise was proven by the assessment of symptom change, functional change, and other physiological measures based on a total of 10 randomized clinical trial studies. CONCLUSION: For patients with vestibular dysfunction, a customized vestibular exercise can be a safe and effective technique for improving dizziness and balance function.

BACKGROUND AND OBJECTIVES: To evaluate the effect of eggshell membrane (ESM) patching for tympanic membrane (TM) perforation, and to investigate correlations between healing time and age, gender, patching time, perforation size, and perforation location. SUBJECTS AND METHODS: One hundred and seventy-five patients diagnosed with traumatic TM perforation at the Department of Otorhinolaryngology-Head and Neck Surgery, Korea University Ansan Hospital, between January 2008 and October 2013. Patients were divided into two groups, according to perforation edge approximation or ESM patching treatment. Healing time was compared between the group that received perforation edge approximation and the group that received ESM patching. Perforation grade, age, onset, and location were also compared between the two groups. RESULTS: ESM patching significantly improved healing time compared to spontaneous healing, especially in patients with moderate or large traumatic TM perforations (≥grade II). However, patient age, gender, perforation location, and especially timing of procedure, did not significantly affect healing time. CONCLUSIONS: ESM patching can be a good treatment choice to promote tympanic membrane healing in large traumatic TM perforations.

OBJECTIVES: Eustachian tube dysfunction has been associated with most cases of middle-ear disease. We aimed to assess the effectiveness of dynamic slow motion video endoscopy (DSVE) as a test of eustachian tube dysfunction. Furthermore, we assessed the correlation of the test with the Valsalva maneuver, the seven-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7), and intraoperative findings of the eustachian tube. METHODS: We retrospectively reviewed medical records from April to September 2014 to identify patients who were diagnosed with chronic otitis media (COM) at Korea University Ansan Hospital. They all underwent surgery because of COM without cholesteatoma and were assessed via the DSVE and ETDQ-7 to determine eustachian tube function. RESULTS: We reviewed 46 COM patients and examined 46 ears with COM and 46 ears on the contralateral side to COM that were thought to be normal. The mean DSVE grade in COM ears was 1.57±0.96, while the mean DSVE grade in contralateral ears was 1.15±0.94. The difference in DSVE between COM ears and normal ears was statistically significant (P=0.006). In the ETDQ-7, a higher score was related to intraoperative obstruction of the eustachian tube (P=0.012). CONCLUSION: DSVE and ETDQ-7 can provide information regarding preoperative status of eustachian tube dysfunction by measuring dynamic structural changes of the eustachian tube in combination with other diagnostic tests.
