Advances in the assessment of cosmetic outcomes, sensory alteration in surgical areas, and health-related quality of life of endoscopic thyroidectomy.

BACKGROUND: Endoscopic thyroidectomy has been preliminarily proven effective and safe for thyroid diseases. The cosmetic outcomes and life quality are critical contents of postoperative assessment. This review will primarily focus on the assessment methods and results related to cosmetic outcomes, sensory alteration of surgical area, and quality of life following endoscopic thyroidectomy. METHODS: A comprehensive search of published articles within the last decade was conducted using the terms "endoscopic/robotic thyroidectomy," "patient satisfaction scores," "questionnaire," "quality of life," and "cosmetic" in PubMed. RESULTS: Assessment methods for postoperative cosmetic satisfaction and sensory alterations encompassed verbal/visual analog scales, scar evaluations, Semmes-Weinstein monofilament tests, and more. The evaluation of postoperative quality of life in endoscopic thyroidectomy involved tools such as SF-36, SF-12, thyroid-specific questionnaires, thyroid cancer-specific quality of life questionnaires (THYCA-QOL), as well as assessments related to voice and swallow function. The cosmetic results of endoscopic thyroidectomy generally surpassed those of open thyroidectomy, while the quality of life in endoscopic procedures was either superior or equivalent to that in open thyroidectomy, especially with respect to general health, role emotion, and vitality. CONCLUSIONS: Assessments of cosmetic outcomes and sensory alterations following endoscopic thyroidectomy predominantly relied on patients' subjective feelings. The objective and subjective perspectives of scar assessments remain underutilized. In addition, postoperative laryngoscopy and voice function assessments in endoscopic thyroidectomy procedures require more attention.

Non-recurrent laryngeal nerve related to thyroid surgery: a report of 5 cases and literature review.

BACKGROUND: Non-recurrent laryngeal nerve, a rare anomaly, passes transversely into larynx with or without its recurrent branches directly arising from the vagus nerve. The paper investigates clinical significance of non-recurrent laryngeal nerve during thyroid surgery. Clinical data from 5 cases of non-recurrent laryngeal nerve and related literature reviews were made to acknowledge its incidence, variant types and matters concerned during thyroid operations. CASE REPORT: 821 recurrent laryngeal nerves were anatomized during 2496 thyroid operations, from which 5 were confirmed to hold non-recurrent laryngeal nerves (0.61%). 3 patients were found to have non-recurrent laryngeal nerves during re-operation because of voice horse after the first operation which improved much after re-operation. The other two patients were recognized during the first operation. All 5 cases were not diagnosed preoperatively. CONCLUSIONS: Non-recurrent laryngeal nerve, a rare anomaly, is very vulnerable during thyroid surgery. It is helpful to avoid injuring non-recurrent laryngeal nerve that identification of the non-recurrent laryngeal nerve and its types.
