Validation of quantitative magnetic resonance imaging techniques in head and neck healthy structures involved in the salivary and swallowing function: Accuracy and repeatability.

Background And Purpose: Radiation-induced damage to the organs at risk (OARs) in head-and-neck cancer (HNC) patient can result in long-term complications. Quantitative magnetic resonance imaging (qMRI) techniques such as diffusion-weighted imaging (DWI), DIXON for fat fraction (FF) estimation and T mapping could potentially provide a spatial assessment of such damage. The goal of this study is to validate these qMRI techniques in terms of accuracy in phantoms and repeatability in-vivo across a broad selection of healthy OARs in the HN region.

Glottic insufficiency caused by vocal fold atrophy with or without sulcus: systematic review of outcome measurements.

Purpose: Identifying outcome measurements instruments (OMIs) to evaluate treatment efficacy in patients with vocal fold atrophy and/or sulcus.

Methods: Systematic review of records published before March 2021 by searching Pubmed and EMBASE. Included studies reported on adults (> 18 year) with dysphonia caused by glottic insufficiency due to vocal fold atrophy with or without sulcus, who were enrolled into a randomized controlled trial, a non-randomized controlled trial, a case-controlled study or a cohort study.

A Psychometric Evaluation of the Dysphagia Handicap Index Using Rasch Analysis.

: The Dysphagia Handicap Index (DHI) is commonly used in oropharyngeal dysphagia (OD) research as a self-report measure of functional health status and health-related quality of life. The DHI was developed and validated using classic test theory. The aim of this study was to use item response theory (Rasch analysis) to evaluate the psychometric properties of the DHI.

Voice outcome in medialisation thyroplasty with and without arytenoid adduction: a prospective comparison using intraoperative voice measurements.

Purpose: Arytenoid adduction as an addition to medialisation thyroplasty is highly advocated by some surgeons in selected cases but deemed less necessary by others in patients with unilateral vocal fold paralysis. This study aims to evaluate the additional benefits on voice outcome of arytenoid adduction in patients with unilateral vocal fold paralysis undergoing medialisation thyroplasty using intra-operative voice measurements.

Design/methods: A prospective study was conducted.

Long-term outcomes of bilateral medialisation thyroplasty in patients with vocal fold atrophy with or without sulcus.

Objective: Evaluate long-term voice outcome after bilateral medialisation thyroplasty in glottic insufficiency due to vocal fold atrophy with or without sulcus.

Methods: Patients after medialisation thyroplasty for vocal fold atrophy with or without sulcus were identified. Long-term post-operative subjective voice outcomes (> 1 year) using Voice Handicap Index-30, subjective ratings on voice aspects and study-specific questionnaire were compared to pre-operative and shorter-term (1 year) values.
