支撑喉内镜下声带注射术治疗慢性肥厚性喉炎

Intracordal injection treatment of chronic hypertrophic laryngitis under self-retaining laryngoscope and endoscope

目的探讨全身麻醉支撑喉内镜下声带注射得宝松治疗慢性肥厚性喉炎的疗效。方法对40例慢性肥厚性喉炎患者在全身麻醉支撑喉内镜下声带注射得宝松,术前、术后分别应用嗓音声学分析、嗓音障碍指数量表及纤维喉镜检查进行评估。结果患者术后频率微扰(jitter)、振幅微扰(shimmer)、噪谐比(NHR)及噪音障碍指数(VHI)得分均较术前明显降低,差异有显著性(P<0.05)。纤维喉镜检查示声带充血、水肿、肥厚术后较术前比:无或仅有较轻者28例(28/40),明显减轻者10例(10/40),变化不明显者2例(2/40)。术后未发现声带萎缩病例。结论支撑喉内镜下声带注射得宝松治疗慢性肥厚性喉炎,疗效显著,并发症少,手术视野清晰,精细准确。

[ Objective ] To study the therapeutic effect of intracordal injection of diprospan on chronic hyper- trophic laryngitis under self-retaining laryngoscope and endoscope. [ Methods ] 40 cases of chronic hypertrophic laryngitis were treated by intracordal injection of diprospan under general anesthesias with self-retaing lai^ngoscope and endoscope. The pre-and post-operative voice were estimated with acoustic analysis, voice handicap index（VHI）, and fribrolaryngoseope. [Results] Jitter, shimmer, NHR and VHI decreased after surgery and the difference was signifieant（P 〈0.05）. The congestion or edema of vocal cord after surgery disappeared： 28 patients （28/40）; obviously lessened： 10 patients（10/40）; unobviously lessened： 2 patients（2/40）. Vocal cord atrophy wasn＇t found after surgery. [ Conclusion ] Vocal cord injection of diprospan under self-retaining laryngoscope and endoscope to treat chronic hypertrophic laryngitis is an effective treatment with seldom complication, clear vision, meticulous and exact operating.
