Prevalence and Prognostic Factors Associated with Early Recovery of Olfactory Dysfunction in COVID-19 Patients.

Background: The prevalence of smell dysfunction, along with its risk factors, has been evaluated in previous literature; however, little has been established regarding its relation to other factors such as disease severity, history of coronavirus disease-2019 (COVID-19) vaccinations, and medical treatment for COVID-19 infection. These factors may impact the overall recovery of olfaction in COVID-19 patients.

Objective: This study investigated the prevalence of early olfactory recovery from COVID-19 infection and its associated factors.

Translation and Validation of the Thai Version of the Nasal Obstruction Symptom Evaluation (NOSE) Scale.

Objective: The Nasal Obstruction Symptom Evaluation (NOSE) was developed to evaluate subjective outcomes of patients with deviated nasal septum and symptomatic nasal obstruction. Considering the differences in individuals' cultural, cross-cultural translation, adaptation, and validation of the instrument are necessary. The current study aimed to translate and validate the Thai version of the NOSE Questionnaire for patients with nasal septum deviation.

Schwannoma Arising in Nasopharynx: A Case Report and Literature Review.

Schwannoma in paranasal sinus has been known as a rare tumor in this origin. This study reports on primary schwannoma arising in the nasopharynx, which is an uncommon location. A 36-year-old female presented with nasal obstruction for one month.

Corticosteroid nasal irrigation as early treatment of olfactory dysfunction in COVID-19: A prospective randomised controlled trial.

Objective: This study aimed to evaluate the efficacy of corticosteroid irrigation compared to saline to no nasal irrigation in COVID-19 patients with olfactory loss.

Design And Setting: A randomised controlled study was conducted at the Otolaryngology-Head & Neck Surgery Department, Ramathibodi Hospital, Faculty of Medicine, Mahidol University.

Participants: Two hundred thirty-seven COVID-19 participants with a new-onset smell loss were recruited into the study.

Comparison of sinus distribution between nasal irrigation and nasal spray using fluorescein-labelled in patients with chronic rhinosinusitis: A randomised clinical trial.

Objective: This study aims to compare the potential sinus distribution between high-volume nasal irrigation and nasal spray in chronic rhinosinusitis (CRS) patients who have not undergone sinus surgery.

Design And Setting: A randomised clinical study was conducted at the Otolaryngology-Head & Neck Surgery Department, Ramathibodi Hospital, Faculty of Medicine, Mahidol University.

Participants: Forty patients undergoing endoscopic sinus surgery (ESS) for CRS.

Inferior Meatus Augmentation Procedure (IMAP) to Treat Empty Nose Syndrome: A Pilot Study.

Our understanding of empty nose syndrome (ENS) continues to evolve. Prior studies evaluating airway augmentation to treat ENS did not use validated disease-specific questionnaires, making the true impact of these surgeries unclear. We present a case series of 10 patients with ENS (11 procedures) who underwent the inferior meatus augmentation procedure (IMAP) between September 2014 and May 2017.

The effect of topical epinephrine 1:1000 with and without infiltration of 1% lidocaine with epinephrine 1:100,000 on endoscopic surgical field visualization: a double-blind randomized controlled study.

Background: The objective of this study is to determine whether the infiltration of 1% lidocaine with 1:100,000 epinephrine in addition to topical application of 1:1000 epinephrine significantly improves surgical field grading scale score over topical 1:1000 epinephrine alone.

Methods: A prospective, double-blind, randomized, controlled study was performed of 40 patients undergoing bilateral endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). Patients were enrolled and randomly assigned to receive infiltration with 1% lidocaine with 1:100,000 epinephrine on 1 side of the nasal cavity vs plain saline on the other side in preparation for ESS.

The Upper Airway Nasal Complex: Structural Contribution to Persistent Nasal Obstruction.

Objective: To determine the contribution of the nasal floor and hard palate morphology to nasal obstruction for nonresponders to prior intranasal surgery.

Study Design: Retrospective case-control study.

Setting: Tertiary academic center.

The Horizon Sign and Frontal Bar: Two Topographic Landmarks to Confirm Endoscopic Frontal Sinusotomy.

Confirming a thorough dissection of the frontal sinus during endoscopic sinus surgery can be challenging, and some surgeons would benefit from reliable topographic landmark identification to ensure completion of this sinus dissection. We defined (1) the "horizon sign" as the curvilinear shadow of the posterior table cast superiorly upon the anterior table of the frontal sinus at the acute angle of their meeting point and (2) the "frontal bar" as a sagittal septation at the union of the anterior/posterior tables. A cadaveric study, followed by an intraoperative consecutive case series, was performed to evaluate these 2 landmarks as indicators of complete dissection.

Comparison of outcomes following culture-directed vs non-culture-directed antibiotics in treatment of acute exacerbations of chronic rhinosinusitis.

Background: Acute exacerbations in patients with chronic rhinosinusitis (CRS) are often treated with courses of systemic antibiotics. Poor correlation between microbiologic culture results and the sinus microbiome in CRS has caused increased debate as to the relevance of culture-directed antibiotics. There is currently sparse data comparing outcomes of culture-directed antibiotics vs non-culture-directed antibiotics for treatment of CRS.

The prevalence of Eustachian tube dysfunction symptoms in patients with chronic rhinosinusitis.

Background: While Eustachian tube dysfunction (ETD) is a known comorbidity of chronic rhinosinusitis (CRS), the prevalence of ETD symptoms in the CRS population is poorly understood. We sought to determine the cross-sectional prevalence of ETD in patients with CRS using the validated Eustachian Tube Dysfunction Questionnaire (ETDQ-7) and to correlate ETDQ-7 scores with 22-item Sino-Nasal Outcome Test (SNOT-22) scores, endoscopy scores, and computed tomography (CT) scores.

Methods: A total of 101 patients with confirmed CRS completed the ETDQ-7 and SNOT-22 at their initial visit to our rhinology clinic.
