BACKGROUND: Voice and swallowing alterations are common complaints after thyroidectomy, even in the absence of laryngeal nerve impairment. However, voice and swallowing functions after robotic thyroidectomy have not been thoroughly investigated. This study compared the functional outcomes for voice and swallowing after robotic thyroidectomy and conventional open thyroidectomy. METHODS: The study prospectively analyzed the voice and swallowing functions of patients with thyroid nodules who underwent robotic thyroidectomy by a gasless unilateral axillo-breast (GUAB) approach (50 cases) or by conventional open thyroidectomy (61 cases) from September 2009 to October 2010. Videolaryngostroboscopy or flexible laryngoscopy was performed pre- and postoperatively. Subjective voice and swallowing alterations were assessed by questionnaire preoperatively and then 1 day, 1 week, 1 month, 3 months, and 6 months postoperatively. In addition, objective acoustic voice analysis was performed using a Multidimensional Voice Program, with Voice Range Profiles and maximum phonation times measured preoperatively and then 1 week, 1 month, 3 months, and 6 months postoperatively. RESULTS: Subjective postoperative voice function was significantly better in the robotic group at 1 day, 1 month, and 3 months postoperatively than in the open group. The mean values of fundamental frequency, jitter, shimmer and noise-to-harmonic ratio before and after surgery did not differ between the two groups. However, the frequency range and the highest frequency were significantly better in the robotic group than in the open group at 3 months postoperatively. Subjective swallowing function did not differ between the two groups. CONCLUSION: Postoperative voice function is better with robotic thyroidectomy using the GUAB approach than with conventional open thyroidectomy. This is an advantage of robotic thyroidectomy by the GUAB approach in addition to the excellent cosmesis.
