[The use of laryngostroboscopy in diagnostics and results evaluation of treatment of patients with organic lesions in the larynx]

Abstract

Introduction: The aim of the work was to evaluate effects of the surgical treatment and postoperative rehabilitation of the patients with organic lesions of the larynx using laryngostroboscopy.

Material and methods: A group of 110 patients of both sex was covered by the studies, aged 19-65, who underwent surgical treatment due to organic lesion in the larynx. The voice was assessed using the perceptive GRBAS scale and the laryngostroboscopic examination following and preceding the surgical treatment and foniatric rehabilitation (30 days after the operation). Direct microlaryngoscopic procedures were performed under local intratracheal anaesthesia, whereas the CO2 laser was used in the surgery in 18.2% cases and the other cases (81.8%) had the traditional technique applied. RESULTS OF THE STUDIES: In the studied material the following was found: chronic hypertrophic laryngitis in 46.4% of the patients, Reincke's laryngeal oedema in 29.1% of the patients, vocal cord polyp in 22.7% of the patients and laryngeal papilloma in 1.8% of the patients. The voice evaluation based on the GRBAS scale indicated that better voice improvement after the treatment and rehabilitation was found in the patients with Reincke's oedema and vocal fold polyp rather than in those with chronic laryngeal hypertrophy. The majority showed the degree of hoarseness, rough voice, blowing voice, weak and tight voice in the scale of either 0 or 1, contrary to the evaluation preceding the surgery. No better voice improvement was achieved in the GRBAS scale in the patients with laryngeal papilloma. On the grounds of the laryngostroboscopic examination it was found that the best voice improvement occurred after the surgical treatment and rehabilitation of the patients suffering from Reincke's oedema and vocal cord polyps.

Conclusions: On the basis of the GRBAS scale and laryngostroboscopic examination of the patients after their surgical treatment and rehabilitation the best results in the voice quality were found in the patients with laryngeal polyps and Reincke's oedema whereas the worst results occurred in the patients with laryngeal papilloma.
