We investigated the distribution of medical service uses for Bell’s palsy and Ramsay Hunt syndrome between medicine and traditional Korean medicine using the National Health Insurance Service National Sample Cohort data of Korea from 2006 to 2015. Patients were identified with diagnostic codes and medication or treatment claim codes. For Bell’s palsy, there were 5,970 (68.8%) patients who used traditional Korean medical service only, whereas for Ramsay Hunt syndrome, there were 749 (93.6%) patients who used medical service only.The proportion of traditional Korean medical service use was higher than that of medical service use in patients with Bell’s palsy, while the opposite was found in patients with Ramsay Hunt syndrome.

BACKGROUND AND OBJECTIVES: The main treatment modality of sinonasal benign tumor is surgical resection, and the endoscopic intranasal approach has been commonly performed since the 1990s. The objective of this study was to evaluate the recurrence rates of different sinonasal benign tumors and to analyze the diverse approaches used in their surgical treatment. SUBJECTS AND METHOD: In 270 patients who were histopathologically diagnosed with sinonasal benign tumor during a period of 20 years, histopathologic type, treatment approach, interval between first treatment and recurrence, and recurrence rate according to treatment approach were analyzed. RESULTS: Recurrence rate was higher with the intranasal approach than with the extranasal approach in inverted papilloma and angiofibroma, but the differences were not statistically significant. The proportion of the intranasal approach during the latter 10 years was higher than that during the former 10 years. There was no significant differences between the recurrence rate during the former 10 years and that during the latter 10 years for both intranasal and extranasal approaches. CONCLUSION: Based on tumor location and stage and skill of the surgeon, the intranasal approach can replace the extranasal approach with no major changes in treatment outcome.

BACKGROUND AND OBJECTIVES: Patulous Eustachian tube (PET) causes troublesome autophony. We treated PET using tragal cartilage chip insertion to fill in the concavity within the tubal valve and evaluated the feasibility of this method. SUBJECTS AND METHODS: This study used a prospective design. Eleven patients with PET disorder were included. Tragal cartilage chip insertion via a transcanal approach into the Eustachian tube (ET) was performed in 14 ears of those patients. They were followed-up for at least 12 months after surgery and were evaluated by symptom questionnaire scores. RESULTS: The average follow-up was 16.4 months. Thirteen of fourteen ears received immediate complete relief of autophony symptoms. Autophony symptoms at the last follow-up were as follows: four ears (28.6%) had complete relief; five ears (35.7%) showed satisfactory improvement; four ears (28.6%) showed significant but unsatisfactory improvement; and one ear (7.1%) was unchanged. The PET symptom questionnaire in the affected ears showed a significant reduction in autophony (p=0.047) and improvement in breathing sound conduction (p=0.047). There were no complications such as otitis media or occlusion symptom. CONCLUSIONS: Transtympanic cartilage chip insertion into the ET provides a safe and accessible surgical option for the treatment of PET.

Objective: : This study aims to investigate the incidence of vestibular schwannoma (VS) and demographic characteristics in Korea using population-based National Health Insurance Service data. Methods: : This study analyzed Korean National Health Insurance Service data from 2005 to 2020, based on the International Classification of Diseases, 10th version, Clinical Modification codes D333 and D431. Only those patients who had undergone magnetic resonance imaging and audiologic tests were considered definitive cases. Demographic variables included age, sex, treatment modality, hypertension, diabetics, dyslipidemia, smoking history, alcohol history, and income status. Results: : The total number of VS patients was 5751. The average incidence rate was 0.71 per 100000 from 2005 to 2020, and the annual incidence rate increased from 0.33 in 2005 to 1.32 in 2019 but decreased to 0.80 in 2020. Incidence was highest in those aged 60–69 years (1.791) and lowest in those younger than 20 years (0.041). Incidence was higher in females, and the number of patients who received radiosurgery (46.64%) was largest compared to the wait and scan group (37.96%), microsurgery group (12.85%), or the group who received both (2.56%). Diabetes, dyslipidemia, and alcohol consumption increased the risk of VS, while cigarette smoking reduced the risk of VS. Conclusion : The incidence of VS exhibited an increasing trend from 2005 to 2019. Radiosurgery (46.64%) was the most common treatment modality. Diabetes, dyslipidemia, and alcohol consumption increased the risk of VS, while cigarette smoking reduced the risk of VS.

BACKGROUND AND OBJECTIVES: Auditory brainstem implantation (ABI) is another option for hearing rehabilitation in non-neurofibromatosis type 2 patients who cannot undergo cochlear implantation (CI). However, the average performance of ABI is worse than that of CI. We analyzed the psycho-electrical parameters of each electrode and psycho-acoustic response to different frequency sounds in nontumor patients with ABI. SUBJECTS AND METHOD: Sixteen patients with ABI from July 2008 to May 2013 were included in the study. They were followed up for 4 to 56 months. Among them, 12 were prelingual deaf with a narrow internal auditory canal or cochlear ossification. The remaining four were post-lingual deaf adults with severely ossified cochleae. We analyzed the electrical parameters [impedance, threshold level (T level), and dynamic range] of each of the 12 electrodes. We also evaluated the sound field pure-tone threshold, Ling 6 sound detection-identification test (Ling 6 test), and pitch ranking data of these patients. RESULTS: The impedance, T level, and dynamic range did not significantly differ among electrodes. However, the pure-tone threshold to sound field stimulation was elevated in the high tone area, where more variables were found than in the low frequency area. Patients could not identify /S/ and /Sh/ sounds in the Ling 6 test. The mean T level and the dynamic range of the three highest pitch-perceiving electrodes in each patient was higher and narrower, respectively, than those of the three lowest pitch-perceiving electrodes. CONCLUSION: The nontumor patients with ABI have difficulty perceiving high pitch sound. More sophisticated penetrating type electrodes and, if possible, bimodal stimulation with CI, could be considered.

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.
