| Abstract |
Objective:To investigate the therapeutic effect of SVF-gel in unilateral vocal cord paralysis. Methods:his investigation presented a retrospective study of SVF-gel auto-transplantation in 22 patients with unilateral vocal cord paralysis from June 2017 to December 2018 in otolaryngology head and neck surgery of Nanjing Tongren Hospital. Under the general anesthesia support laryngoscope, the medial thigh was selected as the fat supply area. SVF-gel was obtained by SVF-gel technology. The SVF-gel was transplanted into the vocal cord muscle and the paraglottic space. The laryngography was performed before and after the operation. The voice was analyzed and compared to evaluate the therapeutic effect. Results:SVF-gel was successfully transplanted in all 22 cases. The stroboscopic laryngoscopy showed that the vocal cords vibrated well and the glottis closed normally. The results of GRBAS showed that the voice quality of the patients at 12 and 18 months after the operation was significantly improved. The voice analysis showed that the maximum phonation time of the patients at 12 and 18 months after the operation increased. The basic frequency increased. The basic frequency perturbation, amplitude perturbation and standardized noise energy decreased significantly（P<0.05）. Conclusion:SVF-gel auto-transplantation can effectively improve the voice quality of unilateral vocal cord paralysis and the long-term effect is stable.
