RESUMEN
Background and Objectives@#The 10-item Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) is a recently developed questionnaire for assessing both nasal obstruction and nasal cosmetic satisfaction. It is widely used in rhinoplasty clinics based on its high level of reliability and efficacy in Western countries. In this study we evaluated the validity of the Korean version of the SCHNOS (K-SCHNOS).Subjects and Method The SCHNOS was translated into easily-understandable Korean following the guideline of the developers. Twenty-seven patients undergoing rhinoplasty and a control group of 29 non-rhinoplasty patients completed K-SCHNOS twice at intervals of 2 weeks regardless of pre- or postoperative state. The K-SCHNOS was evaluated for internal consistency, test-retest reliability, and validity. @*Results@#Of the 56 study participants, 39 (69.6%) were male and 17 (30.4%) were female, with the mean (standard deviation) age of 33.5 (12.9) years. Both obstructive domain and cosmetic domains showed high internal consistency with their respective Cronbach’α values being 0.92 and 0.91. The correlations in the test-retest analysis for each item were acceptable, ranging from 0.6-0.82. The association between the obstructive domain and cosmetic domain was 0.48 (95% confidence interval, 0.32-0.61), indicating a very weak correlation. @*Conclusion@#The K-SCHNOS has proven to be a reliable and valid questionnaire to be used by Korean-speaking patients undergoing functional or cosmetic rhinoplasty.
RESUMEN
Objectives@#. To investigate the correlation of objective audiometry with user satisfaction as measured with the questionnaire scores. @*Methods@#. Twenty patients with hearing loss, who agreed to wear a hearing aid and were referred for hearing aid fitting, were included in this prospective clinical study. All patients used the in-the-canal type of Wide7 hearing aid provided by BSL Co., Ltd. We performed the Korean version of the Hearing Handicap Inventory for the Elderly (K-HHIE) and the International Outcome Inventory for Hearing Aids (K-IOI-HA) before and 1, 3, and 6 months after wearing the hearing aid. We also performed pure tone audiometry (PTA), speech audiometry (SA), functional gain (FG), hearing in noise test (HINT), and central auditory processing disorder tests, such as frequency pattern test (CA-f), duration pattern test (CA-d), and dichotic test (CA-Di). Patients were divided into two groups (group A-HHIE, improved; group B-HHIE, same or worse) by comparing the score of K-HHIE before and 6 months after wearing the hearing aid. In the 6-month K-IOI-HA questionnaire, 21 points were considered as the average score. Based on this, we further divided patients into two groups (group A-IOI, >21 points; group B-IOI, ≤21 points). @*Results@#. Group A-HHIE included six patients and group B-HHIE included 14 patients. In PTA, SA, HINT, CA-d, and CA-Di, group A-HHIE showed higher improvements than group B-HHIE, which were not statistically significant. Group A-IOI included 12 patients and group B-IOI included eight patients. No statistically significant difference was noted in the improvement of audiometric results over a period of 6 months after wearing the hearing aid between groups A-IOI and B-IOI. @*Conclusion@#. There were no significant and consistent audiometric results to reflect patient’s satisfaction with the hearing aid. Therefore, when analyzing the hearing aid-fitting outcome, both the objective audiometric tests and subjective questionnaire should be performed together for validating hearing aid performance.
RESUMEN
BACKGROUND AND OBJECTIVES: We evaluated the correlation between video head impulse test (vHIT) and dizziness handicap inventory (DHI), which is commonly used to quantify severity of dizziness in vestibular neuritis (VN). SUBJECTS AND METHOD: Twenty VN patients undergoing vHIT either at the acute or follow-up stages of treatment were assessed by DHI questionnaire. Gain and gain asymmetry (GA) were correlated with DHI scores and abnormal vHIT rates were compared according to the severity of dizziness (mild ≤30; moderate-to-severe ≥32). RESULTS: vHIT gains significantly increased from the acute to follow-up stages (from 0.45±0.18 to 0.70±0.25), whereas GA and DHI scores decreased (GA, from 0.36±0.15 to 0.22±0.18; DHI scores, from 35±26 to 23±23). Although vHIT gains or GA showed no correlation with DHI scores at the acute stage, vHIT gains showed significant correlation with DHI scores at the follow-up (R-sq=0.32, p=0.01) stage. vHIT gains and GA did not differ according to the severity of dizziness during the acute stage; however, vHIT gains (0.78±0.25) of patients with mild dizziness were significantly higher than those (0.51±0.14) with moderate-to-severe dizziness at the follow-up stage. During the follow-up, all patients with moderate-to-severe dizziness showed abnormal vHIT gain, but 43% of patients with mild dizziness showed abnormal vHIT gain, showing a significant difference (p<0.05). CONCLUSION: Reduced vHIT gain was significantly correlated with high degrees of dizziness at the follow-up, but not at the acute stage, suggesting that high-frequency canal dysfunction is contributed in part by the subjective dizziness at the follow-up. Our findings suggest that vHIT might give an indirect evidence for implementing vestibular rehabilitation for enhancing impaired vestibular function and relieving subjective dizziness.
