ABSTRACT
OBJECTIVES: This study aimed to assess the clinical efficacy of injection laryngoplasty using ultrasound marking in patients with unilateral vocal fold paralysis after thyroidectomy compared with injection laryngoplasty without ultrasound marking.
METHODS: Ten patients with unilateral vocal fold paralysis after thyroidectomy were retrospectively analyzed. There were five patients in the ultrasound marking group and matched five patients in the non-ultrasound marking group. Auditory-perceptual evaluation, acoustic analysis, aerodynamic analysis, and Voice Handicap Index-30 were performed on all patients before and 1 month after injection laryngoplasty.
RESULTS: In all patients, auditory-perceptual parameters and the Voice Handicap Index-30 revealed statistically significant improvements following injection laryngoplasty. No adverse effects were observed in any patient. The Voice Handicap Index-30 and the injection laryngoplasty procedure time were substantially reduced in the ultrasound marking group compared to that in the non-ultrasound marking group. However, other parameters did not exhibit a statistically significant difference between the two groups before and 1 month after injection laryngoplasty.
CONCLUSION: Injection laryngoplasty with ultrasound marking is an easy, rapid, and convenient method for patients who experienced unilateral vocal fold paralysis following thyroidectomy.
