Abstract:
OBJECTIVETo evaluate the curative effects of Betamethasone for treatment of voice hoarseness of chronic hypertrophic laryngitis.
METHODSFrom July, 2001 to December, 2002, 48 cases of the chronic hypertrophic laryngitis had been treated by injected of Betamethasone at vocal cords. Fundamental frequency (FO), jitter, shimmer, normalized noise energy (NNE) acoustics' parameters were tested and paired t test were calculated. The voice quality of 1 month and 6 months after treatment were synthetically graded, one-way ANOVA and the DANCAN test were conducted.
RESULTSEight cases were injected under surface anesthesia with indirect laryngoscopy at the clinic service. Thirty-eight cases were injected under general anesthesias with micro-laryngoscopes. After six months following up, the voice hoarseness was obviously improved, the congestion or oedema of vocal cord was lessened, and the voice quality was improved as well. The results of F0, jitter, shimmer, NNE acoustics' parameters after treatment 6 months showed: 8 of 48 cases (17.39%) had treatment effect, 22 out of 48 cases (47.83%) had obviously effect, 10 out of 48 cases (21.74%) had cured. The total effectiveness had reached 86.96% (40 of 48 cases). Six of 48 cases (13.04%) was failure.
CONCLUSIONVocal cord injection of Betamethasone for the hoarseness of chronic hypertrophic laryngitis is an effective treatment method.
