Task: Question Generation
Input (English): Because of the side effects of Teflon, the risk of infection from the use of collagen, autologous fat resorption, and the lack of alternative substances, injection laryngoplasty tends to be replaced by laryngeal framework surgery as the method of choice for the treatment of unilateral vocal cord recurrent paralysis (LP). The aim of this study was to evaluate the results, for morbidity and voice quality, of treating this paralysis by injection of a silicone suspension elastomer implant (SSEI).', 'The study was retrospective, and 19 patients were included. Average follow-up was 25 months (range: 8.3-43).', 'Each patient underwent clinical and videostroboscopic assessment, and had an electroglottographic recording. Subjective assessment was obtained by self-evaluation. Results were classified as good, fair, or poor, and were based on 2 objective and 3 subjective criteria. A search was made for biologic signs of autoimmune disorders.', 'Good, fair, and poor results were respectively 79%, 16%, and 5%. Each set of subjective data showed voice improvement (P < 0.05). The fundamental frequency range, percentage of irregularity, and aspiration decreased significantly (P < 0.05). There was only one case of postoperative dyspnea, which resolved after steroid injection. No biologic signs of autoimmune disorders were found.
Output (English): Do endoscopic rehabilitation of vocal cord paralysis with a silicone elastomer suspension implant?
