Risk Factors for Rebleeding After Successful Rapid Rhino Packing in Epistaxis Patients.

Background And Objectives: Epistaxis is one of the most common emergencies in otolaryngology, and the recently developed Rapid Rhino nasal pack, a balloon-type nasal packing device, is widely used in emergency departments. Rebleeding after initial treatment increases patients' discomfort and medical costs. The aim of this study was to investigate risk factors for rebleeding in patients treated with Rapid Rhino packing.

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.

Thyroid stimulating hormone suppression and recurrence after thyroid lobectomy for papillary thyroid carcinoma.

Background: Thyroid lobectomy is recommended as the primary treatment for low-risk thyroid cancer. However, recurrence and hypothyroidism may develop after lobectomy, necessitating thyroid hormone supplementation. The 2015 American Thyroid Association (ATA) guidelines recommended post-lobectomy thyroid-stimulating hormone (TSH) suppression.

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.

Feasibility of a deep learning-based algorithm for automated detection and classification of nasal polyps and inverted papillomas on nasal endoscopic images.

Background: Discrimination of nasal cavity mass lesions is a challenging work requiring extensive experience. A deep learning-based automated diagnostic system may help clinicians to classify nasal cavity mass lesions. We demonstrated the feasibility of a convolutional neural network (CNN)-based diagnosis system for automatic detection and classification of nasal polyps (NP) and inverted papillomas (IP).

Alar Lifting Technique for the Correction of Tilted Alar Base.

Background: Frequently, a tilted alar base characterized by a discrepant level of the nostril sill and alar insertion on both sides is encountered in patients seeking rhinoplasty. Herein, we report our surgical technique and outcome of alar lifting technique for correcting tilted alar base.

Methods: The medical records of 18 patients with alar base asymmetry who underwent rhinoplasty using the alar lift technique between January 2014 and December 2019 were retrospectively reviewed.

Prediction of cervical metastasis and survival in cN0 oral cavity cancer using tumour F-FDG PET/CT functional parameters.

Purpose: Oral cavity squamous cell carcinoma (OCC) can spread to the neck without apparent lymphadenopathy. Pretreatment detection or prediction of occult metastasis might contribute to proper management of clinically node-negative (cN0) OCC. We examined the role of tumour quantitative 18-fluorodeoxyglucose (F-FDG) positron emission tomography (PET)/computed tomography (CT) measurements for predicting OCC occult metastasis and survival.

Dual Coaptation of Facial Nerve Using Masseteric Branch of Trigeminal Nerve for Iatrogenic Facial Palsy: Preliminary Reports.

Objectives: Immediate facial nerve substitution or graft technique has been used for the repair of facial nerve defects occurring as a result of tumour dissection. However, some patients report unsatisfactory outcomes, such as difficulty in maintaining resting or smiling symmetry, due to persistent flaccid facial palsy. Here we evaluated the functional outcomes of transferring the masseteric branch of the trigeminal nerve to the facial nerve adjunct to facial nerve graft.

F-FDG PET/CT versus CT/MR imaging for detection of neck lymph node metastasis in palpably node-negative oral cavity cancer.

Purpose: Subclinical lymph node (LN) metastasis is associated with poor survival outcome in oral cavity squamous cell carcinoma (OCC), which alleges elective neck LN dissection. Preoperative detection of metastatic LNs may improve prognosis and proper management of OCC. We examined the clinical usefulness of fluorine 18-fluorodeoxyglucose (F-FDG) positron emission tomography (PET)/computed tomography (CT) for the detection of occult neck LN metastasis in OCC patients in comparison with conventional CT/magnetic resonance (MR) imaging.

A comparison of the 7th and 8th editions of the AJCC staging system in terms of predicting recurrence and survival in patients with papillary thyroid carcinoma.

Objectives: The recently published 8th edition of the American Joint Committee on Cancer (AJCC) tumour-node-metastasis (TNM) staging system was significantly updated following the thyroid cancer-related guidelines to provide better predictability of survival but not focus on recurrence. Therefore, we compared the predictive values of the 7th and 8th editions of the AJCC staging systems for recurrence-free survival (RFS) and overall survival (OS) after thyroidectomy for papillary thyroid carcinoma (PTC).

Methods: This retrospective study included 2930 patients who underwent thyroidectomy and neck dissection for previously untreated PTC between 2006 and 2014.

Idiopathic Unilateral Vocal Fold Paralysis in Older Patients: Characteristics in the Disease Course and Implication of Computed Tomography for Evaluation of Etiology.

Objectives: This study aimed to compare the characteristics of idiopathic unilateral vocal fold paralysis (IUVFP) in elderly versus younger patients, including the diagnostic yield of computed tomography (CT) scans for identifying the structural causes of IUVFP.

Methods: We retrospectively analyzed medical records of the patients initially diagnosed with IUVFP in a single referral tertiary hospital. We compared patients' baseline characteristics, initial symptoms, laryngoscopic findings, and prevalence of structural causes on CT scans with respect to age (younger, <65 years vs older, ⩾65 years).

Comparison of the Clinical Results of Attic Cholesteatoma Treatment: Endoscopic Versus Microscopic Ear Surgery.

Objectives: We aimed to compare clinical outcomes including hearing improvement and cholesteatoma recurrence between endoscopic and conventional microscopic surgeries in patients with attic cholesteatoma.

Methods: We collected data from patients with attic cholesteatoma who were treated using endoscopic (10 patients) and microscopic (10 patients) approaches by a single surgeon. The data were retrospectively reviewed for patient characteristics, intraoperative findings, hearing levels, and follow-up clinical status.

Insects perceive local sex ratio in the absence of tactile or visual sex-specific cues.

Numerous studies have demonstrated adaptive behavioral responses of males and females to changes in operational sex ratio (the ratio of potentially receptive males to receptive females; OSR), and theory often assumes that animals have perfect instantaneous knowledge about the OSR. However, the role of sensory mechanisms in monitoring the local sex ratio by animals and whether animals can perceive local sex ratio in a manner consistent with model assumptions have not been well addressed. Here, we show that mating water striders Gerris gracilicornis respond to local sex ratio even when visual and physical contact with other individuals were experimentally prohibited.
