Deep learning algorithm for the automated detection and classification of nasal cavity mass in nasal endoscopic images.

Nasal endoscopy is routinely performed to distinguish the pathological types of masses. There is a lack of studies on deep learning algorithms for discriminating a wide range of endoscopic nasal cavity mass lesions. Therefore, we aimed to develop an endoscopic-examination-based deep learning model to detect and classify nasal cavity mass lesions, including nasal polyps (NPs), benign tumors, and malignant tumors.

The Relationship Between Lateral Nasal Wall Collapse and Nasal Obstruction.

Objectives: In clinical practice, lateral nasal wall collapse during forced inspiration is widely regarded as a sign of nasal obstruction or criterion indicating nasal valve surgery. This study aims to evaluate the relationship between the degree of lateral nasal wall collapse and subjective nasal obstruction. In addition, factors related to lateral nasal wall collapse were also investigated.

Hypochlorous Acid Versus Saline Nasal Irrigation in Allergic Rhinitis: A Multicenter, Randomized, Double-Blind, Placebo-controlled Study.

Background: Low concentrations of hypochlorous acid (HOCl) have proven antipruritic, anti-inflammatory, and antimicrobial effects without toxicity, although the mechanism has not been fully elucidated.

Objective: The aim of this study was to evaluate the effectiveness of HOCl nasal irrigation to reduce allergic rhinitis (AR) symptoms compared with saline nasal irrigation.

Methods: This was multicenter, randomized, double-blind, placebo-controlled study.

Effect of olfactory bulb atrophy on the success of olfactory training.

Purpose: To evaluate the success of olfactory training in patients with olfactory loss and olfactory bulb (OB) atrophy detected on magnetic resonance imaging (MRI) and other characteristics.

Methods: This study included 48 patients with olfactory loss who underwent a nasal endoscopic examination and MRI before olfactory training. The Korean Version of the Sniffin' Sticks Test was performed before and after training.

Reconstruction of a Severely Damaged Cartilaginous Septum with a Bypass L-Strut Graft using Costal Cartilage.

Objective:  Reconstruction of a weakened septal cartilage is a key procedure for the correction of deformed noses. However, when septal mucoperichondrium dissection is technically challenging, reconstruction of the lower two-thirds of the nose should be performed bypassing the damaged septal cartilage and mucosa. This article summarizes our experience with treating patients with severely damaged septal cartilage with bypass L-strut graft using costal cartilage.

Assessment of Objective Audiometry to Predict Subjective Satisfaction in Patients With Hearing Aids.

Objectives: To investigate the correlation of objective audiometry with user satisfaction as measured with the questionnaire scores.

Methods: Twenty patients with hearing loss, who agreed to wear a hearing aid and were referred for hearing aid fitting, were included in this prospective clinical study. All patients used the in-the-canal type of Wide7 hearing aid provided by BSL Co.

Multifocality of papillary thyroid carcinoma as a risk factor for disease recurrence.

Objectives: Tumor multifocality or bilaterality is associated with increased risk of papillary thyroid carcinoma (PTC) recurrence. However, its prognostic value in clinical outcomes remains controversial. This study aimed to evaluate the association of multifocality or bilaterality with recurrence and survival after total thyroidectomy.

Metabolic tumor volume and total lesion glycolysis predict tumor progression and survival after salvage surgery for recurrent oral cavity squamous cell carcinoma.

Background: This study evaluated the prognostic role of Fluorine 18-fluorodeoxyglucose positron emission tomography/CT ( F-FDG PET/CT) parameters quantitatively measured in patients with recurrent oral cavity cancer.

Methods: Cox proportional hazards regression analyses were used to assess the associations between quantitative F-FDG PET/CT parameters and other clinicopathological factors and progression-free survival (PFS) and overall survival (OS).

Results: All of the F-FDG PET parameters (SUV , SUV , SUV , metabolic tumor volume [MTV], and total lesion glycolysis [TLG]) were significantly associated with poor PFS and OS outcomes after salvage treatment (P < .

Reliability and validity of the Korean version of the Questionnaire of Olfactory Disorders.

Background: The Questionnaire of Olfactory Disorders (QOD) is a self-report questionnaire that provides subjective information about olfactory dysfunction. The QOD is widely used in clinical practice because of its high level of reliability and efficacy in Western countries. In this study we evaluated the reliability and validity of the Korean version of the QOD.

Changes of video head impulse test results in lateral semicircular canal plane by different peak head velocities in patients with vestibular neuritis.

Background: The peak head velocity influences on the video head impulse test (vHIT) results, but it has been not known how much the difference is.

Aims: To evaluate the clinical evidence for the superiority of high-velocity compared to low-velocity vHIT.

Material And Methods: vHIT was performed in 30 patients with vestibular neuritis using two peak head velocities (mean 80 vs.
