Presbyphonia is the physiological process of aging voice that leads to atrophy of the vocal folds, morphological changes in the coverage mucosa, muscles, and cartilages. Aim: To assess the quality of voice after injection laryngoplasty. Material and methods: The material included 26 patients with presbyphonia (60–81 y.o.). Preoperative and postoperative examination included laryngovideostroboscopy (LVS), perceptual voice assessment (GRBAS), objective acoustic analysis (MDVP). Patients underwent injection laryngoplasty. Follow-up examinations were conducted 6 months postoperatively. Results: The postoperative LVS examination showed that in all cases the phonatory gap was partially or totally closed. Perceptual voice quality (GRBAS) was improved and the results were stable in the follow up periods. MDVP showed a significant statistical improvement within the group of amplitude (APQ, Shim, vAm) and frequency parameters (Jita); other studied parameters did not change significantly, although their values decreased after surgery. The differences in value between followup periods were not statistically significant. 42 Prace badawcze Now Audiofonol, 2016; 5(3): 42–46 DOI: 10.17431/898479
