Validation and Classification of the 9-Item Voice Handicap Index (VHI-9i).

The international nine-item Voice Handicap Index (VHI-9i) is a clinically established short-scale version of the original VHI, quantifying the patients' self-assessed vocal handicap. However, the current vocal impairment classification is based on percentiles. The main goals of this study were to establish test-retest reliability and a sound statistical basis for VHI-9i severity levels.

Monitoring the Outcome of Phonosurgery and Vocal Exercises with Established and New Diagnostic Tools.

Instrument-assisted measuring procedures expand the options within phoniatric diagnostics by quantifying the condition of the voice. The aim of this study was to examine objective treatment-associated changes of the recently developed vocal extent measure (VEM) and the established dysphonia severity index (DSI) in relation to subjective tools, i.e.

The Value of Vocal Extent Measure (VEM) Assessing Phonomicrosurgical Outcomes in Vocal Fold Polyps.

Objective: This study aimed to present vocal extent measure (VEM), demonstrate its changes with phonomicrosurgical treatment in patients with vocal fold polyps (VFPs), and to compare its performance to that of established vocal parameters.

Study Design: This is an individual cohort study.

Methods: Microlaryngoscopic ablation was executed in 61 patients with manifestation of VFP (28 male, 33 female; 45 ± 13 years [mean ± SD]).

A comparison of white light laryngostroboscopy versus autofluorescence endoscopy in the evaluation of vocal fold pathology.

Objectives/hypothesis: To prove the diagnostic value of autofluorescence endoscopy (AFE) and white light laryngostroboscopy (WLS) versus the gold standard microlaryngoscopy with histopathological examination in differential diagnostics of laryngeal lesions for experienced phoniatricians and laryngologists, using the PENTAX SAFE-3000 system.

Study Design: Exploratory cohort study.

Methods: High-resolution rigid WLS was executed in 32 consecutive patients with initial manifestation of benign, precancerous, and malignant vocal fold lesions.
