Abstract:
Objective: To analyze the voice rehabilitation of the patients receiving second stage reconstruction with rotatory myocutaneous flap for laryngostenosis after partial laryngectomy or extended partial laryngectomy for laryngeal cancer. Methods: Nineteen patients receiving second stage reconstruction for laryngostenosis were subjected to voice assessment by Dr. Speech software; the values of F0, Jitter, Shimmer and NNE were calculated; the results were compared with before the second stage reconstruction and 15 adult patients with laryngeal papilloma, 20 patients with vocal polyp and 20 normal controls. Results: The F0 value of the patients who undergone second stage reconstruction was obviously higher than that before the second stage reconstruction(P<0.05), and the Jitter, Shimmer and NNE values were obviously lower than those before the second stage reconstruction(P<0.05). The post-construction F0 value was obviously lower than that of patients with laryngeal papilloma(P<0.05); the post-construction F0 and Jitter values were obviously lower than those of patients with vocal polyp (P<0.05); the post-construction Jitter, Shimmer and NNE values were obviously higher than those of normal controls (P<0.05). Conclusion: The voice quality of the patients receiving second stage laryngeal reconstruction has been greatly improved and the patients can regain satisfactory voice functions.
