[Videolaryngostroboscopic examination of treatment effects in patients with chronic hyperthrophic larynges]

Abstract

Introduction: This work aimed at assessing effects of surgical treatment and post-operative rehabilitation of chronic hyper trophic laryngitis by videolaryngostroboscopy and the GRBAS scale.

Material and methods: The examinations were carrie on 50 patients of both sex, including 16 women (32.0%) and 34 men (68.0%) at the age of 19-66, surgically treated due t oedema hypertrophic lesions in the larynx. The voice was assessed by the perceptive GRBAS scale, a subjective voice self-assessment questionnaire, and through pre- and post-therapy videolaryngostroboscopic tests, which were also conducted afte phoniatric rehabilitation (30 days after the operation). Physical therapy (iontotherapy with hydrocortisone and 1% solutio of CaCl2) and respiratory and phonatory exercises were introduced in the rehabilitation.

Results: The GRBAS scale indicate that the patients with the Reincke's oedema and vocal fold polyp showed greater voice improvement after the therapy an rehabilitation than those with chronic hypertrophic laryngitis. Contrary to the assessment carried out before the surgica procedure, the hoarseness level, rough voice, breathing voice, weak voice and tense voice mainly ranged between 0 and scale. In stroboscopy a correct marginal shift and occlusion of the glottis were noticed in each case after eliminating lesion like Reincke's oedema and vocal fold polyp (merely in 6.0% we found a disorder in the marginal shift). In the above patient their voice formation was unrestrained, 69.0% and 75.0% respectively, mid-location of the voice was normal in 92.0% an 88.0%, normal phonation time in 85.0% and 94.0%, and accurate voice setting in 77.0% and 75.0%. In stroboscopy the wors results of the voice assessment were obtained in the laryngeal papilloma patient.

Conclusions: The videolaryngostroboscop seems a perfect diagnostic method in larynx diseases, both in qualifying patients for a surgical treatment and monitorin effects of the treatment and post-operative rehabilitation.
