Abstract
Injection laryngoplasty (IL) continues to evolve as new techniques, approaches, and injection materials are continuously being developed. Although it was performed under general anesthesia in the operating room, IL is now increasingly being performed in an office-based setting. The aim of this prospective interventional study was to compare functional outcomes and patient satisfaction of voice between group A (15 patients) with unilateral vocal fold paralysis undergoing injection laryngoplasty under local anesthesia, versus group B (15 patients) with unilateral vocal fold paralysis undergoing injection laryngoplasty under general anesthesia, by analyzing total Arabic Voice Handicap Index (VHI ) scores and subscale scores preoperatively and post operatively. All results obtained in this study showed that there was no significant difference for the functional outcomes and patients satisfaction of voice obtained for both groups under study. In conclusion, injection laryngoplasty under local anesthesia gives similar results as general anesthesia regards to functional outcomes and patient satisfaction of voice quality by himself as well as by using the VHI.
