| Abstract | Background: Sulcus, scar, paresis and atrophy of the vocal fold are the causes for glottis insufficiency, and disordered propagation of the mucosal wave over the vocal fold. Thus, these are indications for vocal fold injection augmentation. Patients usually complain about dysphonia, though problems with swallowing may also be present. Methods: In order to achieve vocal fold augmentation, the material is injected deep into the thyroarytenoid muscle thereby increasing its volume and reducing glottic insufficiency. Different temporary and long lasting materials can be used depending on patient%s symptoms and prognosis. The procedure can be performed by direct microlaryngoscopy under general anaesthesia. Due to numerous advantages and development of transcutaneous approaches, outpatient based injection technique is becoming more popular. Tissue engineering together with in-depth knowledge of the complex composition of mucosal lamina propria on the vocal folds, and changes during scarring process in it has a big potential for prevention and treatment of vocal fold scar that results in incomplete vocal folds closure during vocal folds adduction. Own experience: Since 2006, patients with glottis insufficiency have been treated by autologous fat injection to one or both vocal folds at the University Department of ORL and CFK, UKCLjubljana. In most patients, the reason for incomplete vocal folds closure is the impaired mobility of the vocal fold, the main symptom being hoarseness and frequent aspiration during drinking. The treatment was successful in the vast majority of patients; their voice quality improved and their swallowing problems were usually reduced or disappeared. Only a small number of patients needed reinjection in a few years% time due to the deteriorated contact between the vocal folds. The subjective improvement is also confirmed by the results of acoustic voice analysis before and after the procedure. | |
