Contamination Assessment in Continuous Positive Airway Pressure Devices Using a Complete Disassembly Cleaning Protocol: Two Years of Experience.

Background And Objectives: Obstructive sleep apnea (OSA) is a prevalent disorder that is commonly managed with continuous positive airway pressure (CPAP) therapy. Although CPAP is clinically effective, issues related to device hygiene and contamination remain understudied. This study aims to present a practical protocol for CPAP disassembly and cleaning and to report the outcomes of its implementation over a 2-year period.

Simultaneous Traumatic Fracture of Nasal Bone and Silicone Implant: Indications for Early Open Revision Rhinoplasty.

Augmentation rhinoplasty with silicone implants is frequently performed in Asian populations. Nasal trauma in individuals with prior silicone-based augmentation may result in concurrent nasal bone and implant fractures, complicating management. The authors describe a case involving a 35-year-old man who sustained blunt facial trauma 5 years post-augmentation with an L-shaped silicone implant.

Delayed Iatrogenic Nasal Hump Induced by Hyaluronic Acid Filler: A Rare Long-Term Complication.

Rhinoplasty is frequently performed in Asian populations, with nonsurgical rhinoplasty using hyaluronic acid (HA) fillers becoming an increasingly popular alternative for patients seeking subtle corrections, those with contraindications to surgery, or individuals preferring temporary, less-invasive solutions. HA fillers are often combined with other minimally invasive procedures, such as barbed thread insertion, to enhance aesthetic outcomes and overcome individual limitations. Although these procedures are generally considered safe, most complications are reported within a short treatment period, allowing for timely management.

Chronic Rhinosinusitis With Nasal Polyps Does Not Affect the Association Between the Nasal Provocation Test and Serum Allergen-Specific Immunoglobulin E Levels.

Background And Objectives: This study compared nasal provocation test (NPT) results between groups with and without chronic rhinosinusitis with nasal polyps (CRSwNP) to investigate whether CRSwNP affects the response to the intranasal allergen challenge.

Methods: We reviewed the medical records of patients who had undergone the NPT, multiple allergen simultaneous test (MAST), and paranasal sinus computed tomography. Patients were diagnosed with CRSwNP based on findings from nasal endoscopy and paranasal sinus computed tomography.

Measurement of Microplastic Release After the Use of Polypropylene Nasal Irrigation Bottles.

Objectives: Microplastics originating from plastic materials may pose risks to human health. This study investigated the presence of microplastics in nasal irrigation fluids collected from reused bottles, focusing on the duration of bottle usage.

Methods: Readily available nasal irrigation bottles made of polypropylene were purchased.

Microbiome and Mycobiome Analyses of Continuous Positive Airway Pressure Devices.

Objectives: Microorganisms are likely present in continuous positive airway pressure (CPAP) devices in daily use. Given the potential risk of infection among CPAP users, we aimed to compare the microbiomes of CPAP devices with those of nasal mucosa samples obtained from patients using these devices.

Methods: We conducted a prospective cohort study at multiple tertiary medical institutions.

Dysphagia and Trismus After Tooth Extraction : Clinical Conondrum.

Clinicians should consider disorders of masticatory muscle including lateral pterygoid muscle as a differential diagnosis in patients presenting with dysphagia and trismus after tooth extraction.

Level of Contamination of Positive Airway Pressure Devices Used in Obstructive Sleep Apnea.

Objectives: No study has yet evaluated the degree of contamination after the total disassembly of continuous positive airway pressure (CPAP) devices. We investigated the extent of contamination of CPAP devices used daily by patients with obstructive sleep apnea (OSA) by disassembling the systems and identifying the factors that influenced the degree of CPAP contamination.

Methods: We conducted a chart review of the medical records of patients with OSA for whom the CPAP devices were disassembled and cleaned.

Complications of a Barbed Thread in Rhinoplasty.

Rhinoplasty using threads has been popular for the benefits of being free from anesthesia, shortness of post-surgical recovery process, and surgery-related complications. Compared with its beneficial aspects, studies that evaluated thread rhinoplasty-related complications are relatively limited. Recently, we experienced a patient who underwent barbed thread rhinoplasty in 12 months before visiting our clinic.
