TWO VIDEOSTROBOKYMOGRAPHIC SOFTWARE PACKAGES FOR EVALUATING OPEN QUOTIENT OF THE VOCAL FOLDS: USER REPORT
Journal Title: Journal of Hearing Science - Year 2017, Vol 7, Issue 4
Abstract
Introduction: Laryngovideostroboscopy (LVS) is the gold standard in diagnosis of the larynx, but the interpretation of the tool is highly de¬pendent on the examiner’s competence and knowledge. An objective measure of LVS, so far used only subjectively, provides a tool for pre¬cise diagnosis of laryngeal diseases. Aim: The aim of the study was to test two different types of videostrobokymographic (VSK) software – Divas and DiagnoScope. We also com¬pared measures of Open Quotient obtained using the two programs. Material and Method: 23 LVS recordings from a group of euphonic people were analyzed with Divas software (Xion Medical) and Diagno¬Scope Specialist software (DiagNova Technologies). Results: The mean age in the study group was 41.1 years (women: 39.6; men: 42.4). The mean OQVSK value averaged from all three parts of the glottis measured by Divas was 0.519 and by DiagnoScope, 0.517. A Student t-test showed no significant differences between the parame¬ters. For all measurements, absolute differences were less than 0.18. In 50% of patients, the differences in measurements did not exceed 0.05 and in 87%, 0.1. The largest differences were observed in the anterior part of the vocal folds. Conclusions: The average values of OQVSK measurements are comparable despite the use of different measurement software. Software availa¬ble on the market with a VSK module requires fine-tuning to limit the recording analysis time as much as possible.
