AI Article Synopsis
- Post-thyroidectomy voice and swallowing changes are often reported, but the effects of robotic thyroidectomy had not been fully explored prior to this study.
- The study assessed and compared these functions in patients undergoing robotic thyroidectomy versus traditional open surgery, using various objective and subjective evaluation methods over several months.
- Results indicated robotic thyroidectomy led to significantly improved voice function shortly after surgery, although swallowing function remained comparable between both methods.
Article Abstract
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.

Purpose: This scoping review aimed to explore the use of volitional voice tasks in assessing swallowing-related outcomes and to evaluate their therapeutic impact on swallowing disorders, including their effects on swallowing biomechanics.
Method: This scoping review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. A literature search was performed across multiple databases (PubMed, Web of Science, and Scopus), and additional records were identified through manual searches.

Recurrent laryngeal nerve palsy remains a significant complication following minimally invasive esophagectomy for esophageal cancer. Despite advancements in surgical techniques and lymphadenectomy precision, the incidence of recurrent laryngeal nerve palsy has not been improved. Recurrent laryngeal nerve palsy predominantly affects the left side and may lead to unilateral or bilateral vocal cord paralysis, resulting in hoarseness, dysphagia, and an increased risk of aspiration pneumonia.

Limited access to the comprehensive assessment of disorders of the upper aerodigestive tract is a barrier to care in rural health facilities. Assessment of the full aerodigestive tract requires a variety of specialists. The inability to access the necessary specialists can result in misdiagnosis, underdiagnosis, and increased associated mortality.

Introduction: Laryngeal muscle physiology is integral to many speech, voice, swallowing, and respiratory functions. A key determinant of a muscle's contractile properties, including its fatigue profile and capacity for force production, is the myosin heavy chain (MyHC) isoform that predominates in the muscle. This study surveys literature on the MyHC compositions of mammalian intrinsic laryngeal skeletal muscle to illustrate trends and gaps in laryngeal muscle fiber typing techniques, models, and concepts.
