BACKGROUND: Neutrophils present as major inflammatory cells in refractory chronic rhinosinusitis with nasal polyps (CRSwNP), regardless of the endotype. However, their role pathophysiology CRSwNP remains poorly understood. We investigated factors predicting surgical outcomes patients focus on neutrophilic localization. METHODS: employed machine-learning methods such decision tree and random forest models to predict CRSwNP. Immunofluorescence analysis was conducted detect human neutrophil...
A clinical diagnosis of Ménière's disease (MD) is made based on medical history and audiometry findings. The 1995 American Academy Otolaryngology-Head Neck Surgery (AAO-HNS) guidelines requires histopathological confirmation endolymphatic hydrops (EH) for a "certain" MD. Symptoms such as dizziness ear fullness are important diagnostic features; however, the descriptions provided by patients frequently vague non-specific. recently developed magnetic resonance imaging (MRI) protocol to...
Increasing recognition of anatomical obstruction has resulted in a large variety sleep surgeries to improve anatomic collapse obstructive apnea (OSA) and the prediction whether surgery will have successful outcome is very important. The aim this study assess machine learning-based clinical model that predict success rate OSA subjects. predicted from learning subjective surgical physician were compared with actual 163 male dominated-OSA Predicted models based on parameters endoscopic findings...
Background: Understanding the characteristics of residual hearing at low frequencies and its natural course in relation to molecular genetic etiology may be important developing rehabilitation strategies. Thus, we aimed explore associated with two most frequent deafness genes: GJB2 SLC26A4 . Methods: Initially, 53 65 subjects were enrolled, respectively. Only those whose audiograms exhibited thresholds ≤70 dB 250 500 Hz, who had least 1-year follow-up period between first last audiograms,...
Excessive collapse of the soft palate and lateral pharyngeal wall narrowing are established causes loud snoring sleep apnea in subjects with obstructive (OSA). Therefore, delicate surgical techniques needed to reshape create sufficient tension wall. This study aimed determine therapeutic outcome favorable indications soft-palate webbing flap pharyngoplasty OSA primary snoring.A total 174 who underwent combined uvulopalatal septoturbinoplasty from August 2015 February 2020 were included this...
<title>Abstract</title> Soft palate webbing flap palatopharyngoplasty (SPWFPP) has been introduced to enhance the stability of lateral pharyngeal wall with minimal post-operative complications by eliminating need for tonsillectomy in obstructive sleep apnea (OSA) patients. We analyzed anatomic findings oropharynx determination outcome OSA patients requiring SPWFPP. Twenty-eight who underwent SPWFPP combined septoturbinoplasty were included this study. Patient medical records, including...
Objectives. Sinonasal squamous cell carcinoma (SqCC) often invades the orbit. The treatment approach for sinonasal cancer that has spread to orbit varies across medical centers and depends on extent of invasion. decision preserve in strategy is made a case-by-case basis results varying outcomes. Currently, multimodal regimen, which may include surgery, chemotherapy, radiotherapy (RT), or concurrent chemoradiotherapy (CCRT), commonly adopted managing cancers. This study aims assess prognosis...
Objectives The frequency of paranasal sinus fungus balls, a common form rhinosinusitis, has increased. Although treatment and causative factors have been well investigated, the evolving nature fungal balls remains unelucidated. This study aimed to investigate analyze changing patterns balls. Methods retrospective analyzed data from 35 participants selected pool 41,497 patients who underwent brain magnetic resonance imaging (MRI) at large health care center. extent was evaluated by grading...
Importance Consumer-level sleep analysis technologies have the potential to revolutionize screening for obstructive apnea (OSA). However, assessment of OSA prediction models based on in-home recording data is usually performed concurrently with level 1 in-laboratory polysomnography (PSG). Establishing predictability using sound recorded from smartphones 2 PSG at home important. Objective To validate performance a model breathing in conjunction home. Design, Setting, and Participants This...
Identifying the sites, severity, and pattern of upper airway obstruction in obstructive sleep apnea is crucial for determining treatment options, particularly surgical plan. Although early methods assessment, such as Muller's maneuver, computed tomography, magnetic resonance imaging awake patients have been utilized to assess physiologic anatomical differences between sleeping showed a limited ability those diagnostic tools. Recently, drug-induced endoscopy (DISE) was introduced useful...
Background and Objectives Wideband tympanometry (WBT) provides information additional to what can be provided by the relms of traditional tympanometry, such as absorbance, resonance frequency, peak pressure. We investigated characteristics WBT in various middle ear disorders, especially for chronic otitis media (COM), otosclerosis, patulous eustachian-tube disorder (ETD).Subjects Method recruited 165 patients who presented 179 normal ears 151 abnormal due COM (113 ears), otosclerosis (14...
Background: Chronic rhinosinusitis (CRS) is further classified as CRS with nasal polyp and without polyp. It also divided into type 2 none-type by immunological endotype. Nowadays, novel biological products targeting inflammation are developed used for the treatment of polyp.Current Concepts: Dupilumab, which inhibits interleukin-4 interleukin-13, omalizumab, targets immunoglobulin E, were recently approved currently being regimen patients recurrent in Korea. Many studies demonstrated enough...
Endoscopic sinus surgery is commonly performed for maxillary (MS) disease, and the surgical extent of MS medial wall or ostium varies. We examined effect on nasal airflow air-conditioning using computational fluid dynamics in five cavity numerical models.
Fibrous dysplasia (FD) is a non-malignant progressive condition, which replaces normal bone and marrow with fibrous tissue woven bone. Sinus mucocele cystic, expansile, destructive lesion that occurs as result of obstruction the sinus ostium secondary to inflammation, trauma, anatomical variation, previous surgery, tumor or FD. Among them, FD combined has been rarely reported. Here we report first case ethmoid mucocele. The patient underwent endoscopic debulking marsupialization was...
Pleomorphic adenoma is one of the most common benign neoplasm salivary glands and resection with enough normal tissue margin important treatment for preventing local recurrence. For palate tumor involving both soft hard palate, palatal fistula easier to occur as post-operative complication after tumor. The palatine aponeurosis anatomical barrier between nasal cavity, we found that by using surgical plane, can do R0 complication. Also, used inguinal full thickness skin graft protect exposed...
