  • Title: [Usefulness of video-laryngo-stroboscopy in the diagnosis of laryngeal pathology].

    Abstract:
    The observation of the glottis and the vocal fold mobility during phonation enables the diagnosis of larynx pathology. Videolaryngostroboscopy (VLSS) facilitates acquiring a precise endoscopic picture and an evaluation of the vocal fold vibratory movements. This method is recognised as an objective, repetitive and non-invasive approach to accelerate early diagnosis in laryngeal carcinoma, vocal nodules, vocal fold paresis, larynx oedema, functional dysphonia and presbyphonia. The mucosal wave is a particularly important parameter in the stroboscopic examination. The absence of mucosal wave indicates microinfiltrations in the T1 stage of glottic carcinoma and vocal hard nodules, the complete form of paretic dysphonia and the severe form of atrophic presbyphonia. The recurrent mucosal wave suggests re-innervation in the paretic dysphonia. Aberrations in the vocal fold vibrations indicate a supraepithelial oedema of the laryngeal mucosa and a functional type of dysphonia, requiring differential therapy. The larynx image recorded on a video tape is a valuable diagnostic evidence that allows monitoring of therapeutic effects and phoniatric rehabilitation.
