Trends in Palate Surgery for Obstructive Sleep Apnea in Korea Over the Past 12 Years.

Background And Objectives: In the past, palate surgery, such as uvulopalatopharyngoplasty (UPPP), was widely performed to treat obstructive sleep apnea (OSA). However, since the introduction of reimbursement for positive airway pressure (PAP) therapy in 2018, it is believed that the frequency of these operations has significantly declined. Despite this, there are currently no definitive data to support this assertion.

Limited Palatal Muscle Resection for the Treatment of Obstructive Sleep Apnea: A Systematic Review and Meta-Analysis.

Limited palatal muscle resection (PMR) is a surgical technique employed to alleviate respiratory disturbances in obstructive sleep apnea (OSA) patients with retropalatal narrowing by reducing soft palate volume and tightening the muscles. Although some previous publications have demonstrated the effectiveness of limited PMR, the overall efficacy and therapeutic role of limited PMR for the treatment of OSA remain uncertain. This study utilized meta-analysis and a systematic literature review to estimate the overall effectiveness of limited PMR in treating OSA.

Incidence disparities of obstructive sleep apnea-associated lung cancer by gender; Korean National Health Insurance data analysis.

Introduction: Obstructive sleep apnea (OSA) is known to increase the risk of various cancers. By analyzing the Korea National Health Insurance Service (KNHIS) registry, the impact of OSA on the lung cancer incidence was analyzed in a retrospective cohort group.

Methods: A retrospective cohort of adult patients newly registered with OSA in the KNHIS data from 2007 to 2017 was included and observed until December 2019 (12 years).

Testicular Cancer Incidence among Obstructive Sleep Apnea (OSA) Patients: South Korean National Health Insurance Data.

Obstructive sleep apnea (OSA) has been linked to an increased risk of acquiring many types of cancer. No data on the prevalence of testicular cancer in OSA patients have been reported in the literature. The goal of the present investigation is to find out the impact of OSA on the incidence of testicular cancer based on the Korea National Health Insurance Service (KNHIS) dataset.

Estimation of the Effectiveness of a Tighter, Reinforced Quarantine for the Coronavirus Disease 2019 (COVID-19) Outbreak: Analysis of the Third Wave in South Korea.

It has been claimed that a tighter, reinforced quarantine strategy was advocated to reduce the transmission of coronavirus disease 2019 (COVID-19) during major outbreaks; however, there have been no prior quantitative studies examining the effectiveness and duration of such a reinforced quarantine. Consequently, the purpose of this research was to determine the impact of a "tighter, reinforced" quarantine during the third COVID-19 breakout wave in South Korea, which occurred between late 2020 and early 2021. The efficacy of the quarantine was determined by comparing the number of newly diagnosed COVID-19 patients between the "prediction model" and "actual observed data.

Weight Loss for Obstructive Sleep Apnea: Pharmacological and Surgical Management.

Obstructive sleep apnea (OSA) is a relatively common sleep disorder characterized by repetitive narrowing or obstruction of the upper airway, including the nasal cavity, pharynx, and larynx, during sleep. OSA can cause a variety of symptoms and/or complications, such as excessive daytime sleepiness, reduced concentration, hypertension, type II diabetes, and stroke. Accordingly, an accurate diagnosis and appropriate treatments are required for OSA.

Clinical Practice Guideline: Clinical Efficacy of Nasal Surgery in the Treatment of Obstructive Sleep Apnea.

Obstructive sleep apnea (OSA) is a common disorder characterized by upper airway obstruction during sleep. To reduce the morbidity of OSA, sleep specialists have explored various methods of managing the condition, including manifold positive airway pressure (PAP) techniques and surgical procedures. Nasal obstruction can cause significant discomfort during sleep, and it is likely that improving nasal obstruction would enhance the quality of life and PAP compliance of OSA patients.

The Effect of Pharyngeal Surgery on Positive Airway Pressure Therapy in Obstructive Sleep Apnea: A Meta-Analysis.

There is controversy about the effect of pharyngeal surgery for obstructive sleep apnea (OSA) on positive airway pressure (PAP) adherence, and the related results of meta-analysis have not yet been available. Therefore, the purpose of this meta-analysis was to assess the effect of pharyngeal OSA surgery on PAP therapy parameters such as optimal pressure levels and usage time. We selected studies investigating optimal PAP levels or usage time before and after pharyngeal OSA surgery, regardless of the study design.

Compliance After Re-Prescription for Positive Airway Pressure in Obstructive Sleep Apnea Patients Who Failed Positive Airway Pressure Therapy.

Background And Objectives: Little is known about studies evaluating positive airway pressure (PAP) compliance after re-prescription. Therefore, the aim of this study was to investigate PAP compliance after re-prescription in obstructive sleep apnea (OSA) patients who failed initial PAP therapy.

Methods: We retrospectively reviewed OSA patients who had received a re-prescription for PAP from March 2020 to June 2021.

Validation Study on Automated Sleep Stage Scoring Using a Deep Learning Algorithm.

Polysomnography is manually scored by sleep experts. However, manual scoring is a time-consuming and labor-intensive task. The goal of this study was to verify the accuracy of automated sleep-stage scoring based on a deep learning algorithm compared to manual sleep-stage scoring.

Clinical Practice Guideline: Nasal Irrigation for Chronic Rhinosinusitis in Adults.

The Korean Society of Otorhinolaryngology-Head and Neck Surgery and Korean Rhinologic Society appointed a guideline development group (GDG) to establish a clinical practice guideline, and the GDG developed a guideline for nasal irrigation for adult patients with chronic rhinosinusitis (CRS).
