The relationship between intravenous olfactory test and taste disorder in patients with olfactory disorder.

Background: The intravenous olfactory test (alinamin test [AT]) is a retronasal olfactory assessment and may evaluate the flavour disorder; however, studies assessing whether AT accurately determines the severity of taste disorders are lacking. Our study aims to evaluate the relationship between AT and subjective taste disorders in the patiensts with olfactory disorder.

Methods: Between April 2019 and March 2020, 228 patients visited our smell clinic reporting olfactory disorders.

Trends in Olfactory Threshold Test Results and Limits of Olfactory Testing in Patients with Parosmia.

Introduction Parosmia poses a clinical challenge due to a lack of established testing methods, leading to underestimated self-reported symptoms. This study investigates olfactory threshold trends, aiming to highlight parosmia prevalence, analyze threshold patterns, and assess diagnostic potential in current olfactory testing. Methods A total of 407 patients who visited our olfactory clinic from April 2009 to September 2015 were categorized into parosmia and non-parosmia groups based on initial visit questionnaires.

Endoscopic surgery for squamous cell carcinoma in the nasal cavity and ethmoid sinus: A retrospective observational study.

Objective: Reports of endoscopic surgery for squamous cell carcinoma of the nasal cavity and ethmoid sinus are limited. Herein, we present a comprehensive account of the results obtained from performing endoscopic surgery based on the concept of en bloc resection.

Methods: This was a retrospective observational study of patients who underwent nasal endoscopic surgery for squamous cell carcinoma of the nasal cavity and ethmoid sinus at a hospital between July 2018 and December 2021.

Assessing parosmia patients: a study on the evaluation method using a self-administered odor questionnaire for parosmia.

Background: Parosmia symptoms are difficult to quantify due to their heterogeneity among patients, and thus a clinical challenge. This study aimed to assess parosmia with Self-Administered Odor Questionnaire for Parosmia (SAOQ-P), a modification of the widely used SAOQ in Japan. The primary objective was to assess the effectiveness of SAOQ-P in identifying parosmia symptoms and its potential integration into the clinical assessment process.
