Introduction: Glottic insufficiency is one of the most frequent causes of voice disorders. There are many treatment modalities, such as voice therapy, laryngeal framework surgery, injection augmentation. Aim: To assess the quality of voice and durability of results in long-term follow up of patients who were treated by injection of hyaluronic acid into the vocal folds and validate indications for hyaluronic acid injection laryngoplasty. Materials and methods: 35 patients suffering from dysphonia, who were referred for injection laryngoplasty. Preoperative and postoperative examinations were based on videostrobolaryngoscopy, patients' voice was assessed using the subjective GRBAS scale, and objective evaluation was performed using Multidimensional Voice Program. All patients underwent medialization laryngoplasty with injection of hyaluronic acid into the vocal folds. Follow-up examinations were conducted 6,12,24 and 36 months after injection. Results: Perceptual voice quality assessed by the GRBAS scale was improved and the results were stabile in long term follow up periods. Multidimensional Voice Analysis showed significant statistical improvement within the group of frequency, amplitude and noise parameters. Conclusions: Injection of the hyaluronic acid into the vocal fold improves quality of voice in patients suffering from glottic insufficiency. Stabile voice improvement confirms the long-lasting effect of hyaluronic acid injection laryngoplasty. Appropriate qualification criteria are essential for effectiveness of injection laryngoplasty.
