Abstract
OBJECTIVES: To evaluate the therapeutic effect on the voice recovery of patients with vocal cord polyps undergoing the microsurgery of preoperative voice therapy.
METHODS: Twenty-six patients diagnosed with unilateral vocal cord polyp under stroboscope, who needed to undergo vocal cord loss resection under supportive laryngoscope, were randomly divided into control group (non-voice training) and treatment group (voice training), with each group of 13 patients. Patients in control group were just treated with surgical operation. Apart from surgical treatment, patients in treatment group received 6 hours intensive vocal therapy one week before the surgery. The therapy courses consist of the propaganda and education of voice care, postoperative vocal instruction and the patients' self-training under the guidance of voice therapists. The acoustic parameters (irregularity, breathiness, grade, jitter and shimmer) of the same patient were collected 24 to 48 hours before the surgery and 14 days after the surgery with Ling WAVES. The results were analyzed with SPSS 19.0.
RESULTS: The differences of all the five preoperative voice parameters between control group and treatment group are not significant; but postoperative breathiness and jitter in treatment group were significantly lower than that in control group, while the differences of irregularity, overall severity and shimmer were not significant between control group and treatment group. In control group, breathiness and jitter were significantly improved after surgery, while the differences of irregularity, breathiness and shimmer were not significant between preoperation and postoperation. In treatment group, all the five voice parameters were significantly improved after surgery. According to the laryngostroboscopic examination, the vocal fold polyps were excised completely in both groups.
CONCLUSIONS: Preoperative voice therapy contributes to the recovery of voice quality of the patients with vocal cord polyps. Combined intervention of surgery and voice therapy is an effective method to treat the patients with vocal cord polyps.
