RESUMEN
We aimed to determine the association between frailty and cognitive status of the elderly population in Korea. We examined data from 9920 elders who participated in the 2020 Survey of Living Conditions and Welfare Needs of Korean Older Persons. Frailty was assessed using the Korean version of the Fatigue, Resistance, Ambulation, Illnesses, and Weight Loss scale. The Korean mini-mental status examination was used to test cognitive function. Several logistic regression analysis was performed, with correction for several confounding variables (socioeconomic, health behavior, psychological characteristics, and functional status), to evaluate the relationship between frailty and cognitive state. Of the elderly population in Korea, 1451 (14.6%) were frail and 5977 (60.3%) were pre-frail. Compared to the non-frail group (20.3%), cognitive impairment was considerably higher in the pre-frail (33.1%) and frail (39.8%) groups. When compared to the non-frail group, cognitive impairment was substantially linked to a higher risk of frailty after adjustment (pre-frail odds ratio [OR]: 1.66, 95% confidence interval [CI]: 1.47-1.88; frail OR: 2.00, 95% CI: 1.68-2.37). When cognitive impairment and frailty subcomponents were present, there was a higher likelihood of severe resistance (OR: 1.89; 95% CI: 1.70-2.11) and ambulation (OR: 1.46, 95% CI: 1.32-1.63) issues. Frailty is associated with cognitive impairment.

Background: Capsular contracture is one of the most common and severe complications after implant-based breast reconstruction. Recently, prepectoral implant-based breast reconstruction using acellular dermal matrix (ADM) has become an alternative to subpectoral implant-based reconstruction. However, risk factors for capsular contracture associated with recent prepectoral reconstruction trends are not well refined yet. Thus, the aim of this study was to determine risk factors for capsular contracture, and share our experience of treating capsular contracture in prepectoral reconstruction. Methods: This retrospective comparative study focused on 110 patients who underwent prepectoral implant-based breast reconstruction with ADM. Risk factors of capsular contracture were analyzed by comparing a capsular contracture group (27 cases) and a non-capsular contracture group (83 cases). Secondary treatment after capsular contracture development was analyzed in capsular contracture group. Results: According to univariate and multivariate analyses of risk factors for capsular contracture, single staged implant-based reconstruction (direct-to-implant), infection, and postoperative radiotherapy were significantly related to the development of capsular contracture. Also, surgical intervention including capsulectomy and capsulotomy with implant change showed a significant higher remission rate than other groups. Conclusions: Our study provides insights into risk factors and treatment choices for capsular contracture after prepectoral implant-based breast reconstruction with ADM. These findings can aid selection of patients, postoperative care and preventative treatment before reconstruction.
RESUMEN
OBJECTIVES: Hearing loss causes numerous functional deficits. However, few studies have been conducted to assess the association between hearing loss and physical inactivity. This study aimed to evaluate the physical activity and sedentary behavior of hearing loss patients and their relation with the use of hearing aids. MATERIALS AND METHODS: We extracted participants over 60 years of age with information on hearing status and physical activities from the eighth Korea National Health and Nutritional Examination Survey conducted from 2019 to 2020. We classified them into four groups: a normal hearing group (≤25 dB), a mild hearing loss group (>25 dB and ≤40 dB), a moderate hearing loss group (>40 dB and ≤50 dB), and a non-serviceable hearing group (>50 dB). Additionally, we extracted hearing aid users with hearing levels exceeding 50 dB. RESULTS: After adjusting other factors, the non-serviceable hearing group walked less frequently than the moderate (p = 0.004) and mild hearing loss group (p < 0.001) and walked less and sat more than the normal hearing group (walking frequency: p < 0.001; walking time: p = 0.020; and sitting time: p = 0.034). Also, the hearing aid users walked more frequently (p = 0.003) and for longer (p = 0.045) than the non-serviceable hearing group. CONCLUSION: Hearing loss is associated with reduced walking and a sedentary lifestyle. The use of hearing aids is associated with improved physical activity. Appropriate interventions, including hearing aids, should be provided to hearing loss patients. LEVEL OF EVIDENCE: 3 (individual cross-sectional study) Laryngoscope, 2024.
RESUMEN
Lymphedema is known to affect as many as 140 to 250 million people worldwide. Approximately 99% of lymphedemas are secondary cases after lymphadenectomy, radiation, or parasite infection. There has been no accurate estimate of the lymphedema population size in South Korea. This study aimed to quantify the epidemiology of lymphedema in South Korea and analyze the clinical characteristics of patients with lymphedema using a nationwide database. This large-scale cross-sectional study included patients who received one of the following three diagnostic codes - Q82.0 (hereditary lymphedema), I97.2 (breast cancer-related lymphedema), and I89.0 (unclassified lymphedema) from the Korean Health Insurance Review and Assessment service between January 2019 and July 2022 at tertiary hospitals, general hospitals, or other hospitals. The demographics of the lymphedema population, medication use, and medical characteristics were identified. Over the last 4 years, the annual incidence of lymphedema has steadily increased and peaked in 2021 with the number 1.85 out of 1000. Of all patients, 81% were located in the upper extremity, and 10.6% had previous cancer. Most patients were diagnosed in general hospitals (53.2%), at orthopedic surgery department (41.9%). On average, lymphedema patients spent 70.17 US dollar for medication and hospitalized for 16.9 days annually after diagnosis. Commonly prescribed medications were Entelon® (Vitis vinifera seed extract) (66.9%), steroids (40.5%), non-steroidal anti-inflammatory drugs (26.5%) and diuretics (21.8%). Only 5.7% of patients received surgery and 19.2% received herbal medicine. This is the first study in South Korea to quantify demographic and medical characteristics of lymphedema patients. These results will contribute to a comprehensive understanding of lymphedema diagnosis and treatment in our nation.

This study aimed to identify the clinical manifestation and implications according to the grading of tumor spread through air spaces in early-stage small (≤2 cm) pathological stage I non-mucinous lung adenocarcinomas. Medical records of patients with pathological stage I tumors sized ≤2 cm were retrospectively reviewed and analyzed. The furthest distance of the spread through air spaces from the tumor margin was measured on a standard-length scale (mm). Enrolled patients were categorized into spread through air spaces (STAS) (-) and STAS (+), and STAS (+) was subdivided according to its furthest distance as follows: STAS (+)-L (<2 mm) and STAS (+)-H (≥2 mm). Risk factors for STAS (+) included papillary predominant subtype (p = 0.027), presence of micropapillary patterns (p < 0.001), and EGFR (p = 0.039). The overall survival of the three groups did not differ significantly (p = 0.565). The recurrence-free survival of STAS (+)-H groups was significantly lower than those of STAS (-) and STAS (+)-L (p < 0.001 and p = 0.039, respectively). A number of alveolar spaces were definite risk factors for STAS (+)-H groups (p < 0.001), and male gender could be one (p = 0.054). In the patient group with small (≤2 cm) pathological stage I lung adenocarcinomas, the presence of STAS ≥ 2 mm was related to significantly lower recurrence-free survival. For identifying definite risk factors for the presence of farther STAS, more precise analysis from a larger study population should be undertaken.
RESUMEN
The purpose of this study was to assess the relationship between quality of life and dementia caregivers. The 2019 Korean Community Health Survey participants were assessed using the Patient Health Questionnaire-9, subjective cognitive decline (SCD) and SCD-related functional limitation, and EuroQol 5-dimension (EQ-5D). Sociodemographic and psychosocial variables were evaluated and compared between participants with dementia caregivers (nâ =â 37,614) and non-dementia caregivers (nâ =â 140,518). The dementia caregivers group reported significantly higher rates of depression, SCD, SCD-related functional restriction, and mean EQ-5D compared to the non-dementia caregivers group (Pâ <â .001). After adjusting for multiple confoundings, the odds ratio (OR) for depression (Patient Health Questionnaire-9â ≥â 10), SCD, SCD-related functional limitation, and lowest quartile of the EQ-5D index scores in the dementia caregivers group were 1.43 (95% confidence interval [CI], 1.29-1.59), 1.30 (95% CI: 1.24-1.36), 1.26 (95% CI: 1.20-1.32), and 1.22 (95% CI: 1.16-1.29), respectively. Physical activity (OR: 1.47; 95% CI: 1.43-1.52), self-control (OR: 1.41; 95% CI: 1.35-1.47), daily activity (OR: 1.55; 95% CI: 1.50-1.60), pain (OR: 1.62; 95% CI: 1.58-1.67), and anxiety/depression (OR: 2.17; 95% CI: 2.10-2.24) were all more common among participants in the dementia caregivers group than in the non-dementia family caregivers group. Depression, SCD, and a lower quality of life are linked to dementia caregivers, especially if there is moderate to severe anxiety or depression.

BACKGROUND: In patients with non-small cell lung cancer (NSCLC), interstitial lung abnormalities (ILA) have been linked to mortality and can be identified on computed tomography (CT) scans. In the present study we aimed to evaluate the predictive value of automatically quantified ILA based on the Fleischner Society definition in patients with stage I NSCLC. METHODS: We retrospectively reviewed 948 patients with pathological stage I NSCLC who underwent pulmonary resection between April 2009 and October 2022. A commercially available deep learning-based automated quantification program for ILA was used to evaluate the preoperative CT data. The Fleischner Society definition, quantitative results, and interdisciplinary discussion led to the division of patients into normal and ILA groups. The sum of the fibrotic and nonfibrotic ILA components constituted the total ILA component and more than 5%. RESULTS: Of the 948 patients with stage I NSCLC, 99 (10.4%) patients had ILA. Shorter overall survival and recurrence-free survival was associated with the presence of ILA. After controlling for confounding variables, the presence of ILA remained significant for increased risk of death (hazard ratio [HR] = 3.09; 95% confidence interval [CI]: 1.91-5.00; p < 0.001) and the presence of ILA remained significant for increased recurrence (HR = 1.96; 95% CI: 1.16-3.30; p = 0.012). CONCLUSIONS: The automated CT quantification of ILA, based on the Fleischner Society definition, was significantly linked to poorer survival and recurrence in patients with stage I NSCLC.

BACKGROUND: This article presents a comprehensive review of data on the impact of facial palsy during the coronavirus disease 2019 (COVID-19) pandemic. The possible causes and pathophysiological mechanisms of changes in the epidemiology of facial palsy during the COVID-19 pandemic are also discussed. METHODS: This multicenter retrospective cohort study included 943 patients diagnosed with Bell's palsy or Ramsay Hunt syndrome. This study compared patient demographics, comorbidities, symptoms, and treatments before the COVID-19 pandemic (from 2017 to 2019) and during the COVID-19 pandemic, from 2020 to 2022). RESULTS: Following the COVID-19 outbreak, there has been a significant increase in the number of cases of Bell's palsy, particularly among elderly individuals with diabetes. Bell's palsy increased after the COVID-19 outbreak, rising from 75.3% in the pre-COVID-19 era to 83.6% after the COVID-19 outbreak. The complete recovery rate decreased from 88.2% to 73.9%, and the rate of recurrence increased from 2.9% to 7.5% in patients with Bell's palsy. Ramsay Hunt syndrome showed fewer changes in clinical outcomes. CONCLUSION: This study highlights the impact of the COVID-19 pandemic on the presentation and management of facial palsy, and suggests potential associations with COVID-19. Notably, the observed increase in Bell's palsy cases among elderly individuals with diabetes emphasizes the impact of the pandemic. Identifying the epidemiological changes in facial palsy during the COVID-19 pandemic has important implications for assessing its etiology and pathological mechanisms of facial palsy disease.

Pure-tone audiometry (PTA) is the gold standard for assessing hearing loss. However, traditional PTA tests require specialized equipment, trained personnel, and a soundproof environment. Recently, smartphone-based PTA tests have been developed as an alternative method for hearing assessment. The aim of this study was to validate the accuracy and reliability of a smartphone application-based audiometry test. This study was conducted to assess the performance of application-based audiometry from November 2021 to January 2022. Pure-tone thresholds were measured using a smartphone application-based PTA test and compared with results obtained using a traditional audiometer in a sound-treated booth. The smartphone application used in this study was the "Care4Ear (Care4ear, version 1.0.6, MIJ Co., Ltd.)". Hearing thresholds less than 35 dB HL were classified as group A, 35-64 dB HL as group B, and 65 dB HL or greater as group C for the classification of hearing levels. We evaluated the accuracy of smartphone audiometry for each group and compared the results of frequency-specific hearing tests. Additionally, we examined the results of smartphone audiometry in individuals (n = 27) with asymmetric hearing loss. Seventy subjects completed both conventional audiometry and smartphone application-based hearing tests. Among the ears assessed, 55.7% were classified as group A, while 25.7% and 18.6% were classified as group B and group C, respectively. The average hearing threshold obtained from conventional pure-tone audiometry was 37.7 ± 25.2 dB HL, whereas the application-based hearing test yielded thresholds of 21.0 ± 23.0 dB HL. A significant correlation (r = 0.69, p < 0.01) was found between the average hearing thresholds obtained from the application-based and conventional pure-tone audiometry tests. The application-based test achieved a 97.4% hit rate for classifying hearing thresholds as class A, but lower rates of 22.2% for class B and 38.5% for class C. Notably, a discrepancy was observed between the hearing threshold measured by the application and the conventional audiometry for the worse ear with asymmetric hearing. The smartphone-based audiometry is a feasible method for hearing evaluation especially in persons with normal hearing. In cases of hearing loss or asymmetric hearing loss, the results of the application-based audiometry may be inaccurate, limiting its diagnostic utility.

BACKGROUND: In breast surgeries, a lactiferous duct leading to lactic glands of breast parenchyma allows direct contamination by normal bacterial flora of the nipple-areola complex. Complete blockage of nipple flora from the intraoperative field is almost impossible. OBJECTIVES: We aimed to analyze the microbiological profile of nipple flora of breast cancer patients who underwent an implant-based immediate breast reconstruction after a total mastectomy, and to evaluate the association of nipple bacterial flora with postoperative complications. METHODS: A retrospective chart review was performed of patients who underwent an implant-based immediate breast reconstruction after a total mastectomy. A nipple swab culture was performed preoperatively. Patient demographics, surgical characteristics, and complications were compared between positive and negative nipple swab culture groups. Microbiological profile data including antibacterial resistance were collected. RESULTS: Among 128 breasts, 60 cases (46.9%) had positive preoperative nipple swab culture results. Staphylococcus epidermidis accounted for 41.4% of microorganisms isolated. A multivariate logistic regression analysis of postoperative complications revealed that the presence of nipple bacterial flora was a risk factor for capsular contracture. Seven cases of postoperative infection were analyzed. In 2 cases (40% of pathogen-proven infection), the causative pathogen matched the patient's nipple bacterial flora, which was methicillin-resistant S. epidermidis in both cases. CONCLUSIONS: Nipple bacterial flora was associated with an increased risk of capsular contracture. Preoperative analysis of nipple bacterial flora can be an informative source for treating clinically diagnosed postoperative infections. More studies are needed to determine the effectiveness of active antibiotic decolonization of the nipple.

INTRODUCTION: Several studies have reported that the number of patients with Bell's palsy varied significantly by month and season. However, few studies have reported the monthly variation in Bell's palsy based on the whole population. We investigated the monthly variation in Bell's palsy in Korea during a long-term period based on whole population data. METHODS: This retrospective study used the data of the National Health Insurance Service of Korea, which included the entire Korean population from 2008 to 2020. The monthly incidence of Bell's palsy per 100,000 was evaluated in total and according to sex, age, and residence. RESULTS: The total average monthly incidence differed significantly by month, with the highest observed in January (9.1 per 100,000) and the lowest in June (7.7 per 100,000) (p < 0.001). The average monthly incidence according to sex, age, and residence also varied significantly by month, with most of the highest values noted in January and the lowest in June. CONCLUSION: There was significant monthly variation in the incidence of Bell's palsy, with the highest in January during the winter and the lowest in June during the summer, based on whole population data over a long-term period in Korea.

Sudden sensorineural hearing loss (SSNHL) is a rapid decline in auditory function that needs urgent medical management. Although etiologic factors, including viral infections, autoimmune diseases, and vascular issues, contribute to the understanding of SSNHL, the condition remains unclear in most cases. Systemic steroids are often used as the first-line treatment because they reduce inner ear inflammation; however, there remains numerous discussions about the effectiveness of alternative treatments. To predict hearing recovery is crucial in patients' counseling with factors, including delayed treatment, vertigo, and other health conditions, which indicate poor prognosis. Herein, we review contemporary research on the treatment approaches and outcome predictions of SSNHL to establish important guidelines for physicians in evaluating and treating patients with SSNHL.
RESUMEN
PURPOSE: Arterial stiffness, represented by estimated pulse wave velocity (ePWV), is the independent surrogate marker for cardiovascular event. The aim of the study was to investigate the significance of ePWV in the treatment outcome of idiopathic sudden sensorineural hearing loss (SSNHL). METHODS: One hundred and ten patients with idiopathic SSNHL who hospitalized between April 2019 and March 2022 were evaluated. Arterial stiffness was calculated with formula for ePWV and other cardiovascular parameters of body mass index (BMI), and serum lipid level was determined. All patients received systemic high-dose steroid therapy and intratympanic steroid injections as a salvage management. Treatment outcome was assessed at 6 months after treatment, and classified as recovery and nonrecovery groups according to hearing recovery. RESULTS: The initial pure-tone hearing threshold was 72.6 ± 23.8 dB and final hearing threshold was 52.63 ± 31.10 dB. After treatment, 60 (54.5%) patients included in recovery group and other 50 (45.5%) were classified as nonrecovery group. Age, days of onset to treatment, BMI, waist circumference, and ePWV were higher in the nonrecovery group compared to recovery group in univariate analysis (p = 0.039, p = 0.049, p = 0.003, p = 0.004, p = 0.007, respectively). In multivariate analysis, days of onset to treatment, BMI, and ePWV were associated with recovery (p = 0.030, p = 0.007, p = 0.022). CONCLUSION: Higher ePWV, a measure of arterial stiffness, was associated with a poor hearing recovery of SSNHL.

Varicose veins usually present in the superficial veins of the lower extremities and are one of the main clinical presentations of chronic venous disease (CVD). Patients' symptoms may vary according to the pathophysiology, location, and severity of CVD. The prevalence of CVD in Korea has been increasing gradually. However, due to its broad clinical spectrum and the subjective nature of its diagnosis using ultrasound, discrepancies in diagnostic and treatment quality may exist among treating physicians. There have been recent efforts to improve the quality of the diagnosis and treatment of varicose veins in Korea by standardizing the diagnostic criteria and the indications for treatment. This study is a comprehensive review of the clinical manifestations and diagnostic criteria of CVD based on the most recent international and domestic guidelines and reports.
RESUMEN
INTRODUCTION: Acute facial palsy, characterized by sudden hemifacial weakness, significantly impacts an individual's quality of life. Despite several predisposing factors identified for acute facial palsy, the specific relationship between diabetes mellitus (DM) and acute facial palsy has not been comprehensively explored in recent studies. The aim of the study was to assess the risk of acute facial palsy in patients with DM using a nationwide population sample cohort. METHODS: DM cohort and non-DM cohort were built using the Korean National Health Insurance Service-Sample Cohort which represents the entire population of the Republic of Korea from January 2002 to December 2019. The DM cohort comprised 92,872 patients with a record of medication and a diagnosis of DM. Individuals who had facial palsy before the diagnosis of DM were excluded. A comparison cohort comprised 1,012,021 individuals without DM matched sociodemographically in a 1:4 ratio. The incidence of Bell's palsy (BP) and Ramsay Hunt syndrome (RHS) were evaluated in both cohorts. The risk factors for acute facial palsy were also assessed. RESULTS: Among the 92,868 patients in the DM cohort, the incidence rate (IR) of BP and RHS were 31.42 (confidence interval [CI], 30.24-32.63) and 4.58 per 10,000 person-years (CI, 4.14-5.05), respectively. Among the 371,392 individuals in the non-DM cohort, the IR of BP was 22.11 per 10,000 person-years (CI, 21.62-22.59) and the IR of RHS was 2.85 per 10,000 person-years (CI, 2.68-3.02). IR ratios for BP and RHS were 1.42 (CI, 1.36-1.48) and 1.61 (CI, 1.43-1.80). In multivariate analysis, DM (hazard ratio [HR] 1.428), age (HR 1.008), and high comorbidity score (HR 1.051) were associated with increased risk of BP, and male (HR 0.803) and living in metropolis (HR 0.966) decreased the risk of BP. And DM (HR 1.615), high comorbidity score (HR 1.078), and living in metropolis (HR 1.201) were associated with increased risk for RHS. CONCLUSION: This study suggests that patients with DM had an increased risk of acute facial palsy including BP and RHS.

BACKGROUND: Lymphovenous anastomosis (LVA) enables lymphatic fluid to drain into the venous system. However, no study has investigated the association between LVA and heart failure (HF) caused by fluid overload in the blood circulating system. The purpose of our study was to determine whether LVA increases the risk of HF and mortality. MATERIAL AND METHODS: This nationwide retrospective study evaluated a total of 1400 lymphedema patients who underwent LVA and two control cohorts with 28 000 lymphedema who did not undergo LVA and 70 000 age-matched and sex-matched participants from the Korean National Health Insurance database were included. Blood pressure, body mass index (BMI), glucose and cholesterol levels, smoking history, and comorbidities were obtained during National Health Insurance Service - Health Screening (NHIS-HealS). The incidence, adjusted risk for HF, and mortality were evaluated. RESULTS: Adjusted HRs for HF were 1.20 (confidence interval [CI], 1.03-1.40) and 1.30 (CI, 1.12-1.50), referenced by the general population control cohort and patients with lymphedema without LVA, respectively. In age, sex, BMI, and smoking status-stratified analyses, heightened risk of HF was evident across all sexes, spanning both young and old age groups, encompassing individuals with various smoking statuses, and those with a BMI of 18.5 or higher. Among these groups, the risk was notably greater in males compared to females, higher in younger individuals as opposed to older ones, and further elevated within the BMI range of 18.5-25. CONCLUSIONS: LVA is associated with an increased HF risk, independent of cardiovascular risk factors and associated comorbidities. This association is prominent in participants aged <50 years, in males, and in the normal-to-obese (BMI ≥18.5 kg/m 2 ) group. Among patients with lymphedema, LVA did not significantly affect mortality.

When individuals listen to speech, their neural activity phase-locks to the slow temporal rhythm, which is commonly referred to as "neural tracking". The neural tracking mechanism allows for the detection of an attended sound source in a multi-talker situation by decoding neural signals obtained by electroencephalography (EEG), known as auditory attention decoding (AAD). Neural tracking with AAD can be utilized as an objective measurement tool for diverse clinical contexts, and it has potential to be applied to neuro-steered hearing devices. To effectively utilize this technology, it is essential to enhance the accessibility of EEG experimental setup and analysis. The aim of the study was to develop a cost-efficient neural tracking system and validate the feasibility of neural tracking measurement by conducting an AAD task using an offline and real-time decoder model outside the soundproof environment. We devised a neural tracking system capable of conducting AAD experiments using an OpenBCI and Arduino board. Nine participants were recruited to assess the performance of the AAD using the developed system, which involved presenting competing speech signals in an experiment setting without soundproofing. As a result, the offline decoder model demonstrated an average performance of 90%, and real-time decoder model exhibited a performance of 78%. The present study demonstrates the feasibility of implementing neural tracking and AAD using cost-effective devices in a practical environment.

Most cases of sudden sensorineural hearing loss (SSNHL) occur without a specific identifiable cause, although vascular factors may serve as potential etiological contributors. Silent infarction refers to ischemic changes observed on imaging studies without accompanying clinical symptoms; however, this condition is clinically significant owing to the increased risk of future stroke. We report a case of left-sided SSNHL accompanied by dizziness in a 62-year-old male patient who was diagnosed with left pontine infarction without any other neurological symptoms. The cochlea and pons receive blood supply from the anterior inferior cerebellar artery; the cochlea lacks collateral vessels and is therefore susceptible to fluctuations in blood flow. This case report provides evidence to support the vascular hypothesis as the etiology underlying SSNHL.
RESUMEN
The impact of deep inferior epigastric artery perforator (DIEP) flap on abdominal wall integrity has been the topic of an ongoing debate with previous studies having reported conflicting results using various imaging modalities. Ultrasonography is a noninvasive, cost-effective, and readily available method for evaluating the changes to the rectus muscle after DIEP flap surgery. In the present study, we aimed to compare rectus abdominis muscle thickness between the operated and non-operated sides using ultrasound imaging. The muscle thickness was measured at the cross point of the midclavicular line and the level of the umbilicus and anterior superior iliac spine using real-time B-mode ultrasonography. The muscle anteroposterior diameters of the pedicle-dissected side and the control side were compared using paired t test. In total 31 patients with a mean follow-up of 70.18 weeks were included. The mean diameters at the level of the umbilicus of the operated and non-operated sides were 8.16â ±â 1.83 and 8.14â ±â 1.43 mm, respectively (Pâ =â .94). The mean thicknesses at the anterior superior iliac spine level were 7.74â ±â 1.85 on the flap harvested side and 8.04â ±â 1.84 mm on the control side (Pâ =â .35). There was no statistically significant difference between the 2 groups. Ultrasonography can be a reliable, inexpensive, and easily usable modality for evaluating donor site complication following DIEP flap. DIEP flap seems to have minimal impact on the abdominal donor site, and it may be safe and versatile to reconstruct the breast after mastectomy.

More people use the internet for medical information, especially YouTube. Nevertheless, no study has been conducted to analyze the quality of YouTube videos about tinnitus in Korea. This study aims to review the contents and quality of YouTube videos on tinnitus. The top 100 Korean YouTube videos on tinnitus were reviewed by a tinnitus expert. This study assessed video details: title, creator, length, and popularity indicators-subscribers, views, and likes. The contents of the video clips were analyzed to determine the relevance, understandability, actionability, and quality of information. Out of 100 tinnitus videos, 27 were created by otolaryngologists, 25 by traditional Korean medicine doctors, 25 by other medical professionals, and 3 by lay persons. Sensorineural tinnitus was frequently dealt, and hearing loss, stress, and noise were introduced as main causes of tinnitus. Otolaryngologists' videos covered verified treatments, but others suggested unproven therapies including herbal medicine or acupressure. Otolaryngologists' videos showed significantly higher understandability and quality of information compared to others (p < 0.001). This study found that tinnitus YouTube videos frequently present low-quality and incorrect material, which could have an adverse effect on patients. Results highlight the need for tinnitus specialists to provide accurate information.
