Status of alternative approaches for thyroidectomy: Is there any evidence to substitute in place of conventional surgery?

Abstract

Over the past 20 years, various alternative cervical minimally invasive (partly endoscopically assisted) and extracervical endoscopic (partly robot-assisted) approaches have been developed. All of these alternative access methods aim at optimizing the cosmetic results. In principle, the indication for the use of alternative access procedures does not differ from that for conventional surgery. Nonetheless, appropriate experience in traditional thyroid surgery and suitable patient selection, taking into account thyroid volumes and the under-lying pathology, are important prerequisites. General contraindications for an alternative approach are large goiter with symptoms of compression, advanced thyroid carcinoma, recurrent interventions or previous radio-therapy in the operating area. The alternative surgical approaches to the thyroid can be divided into cervical minimally invasive, extracervical endoscopic (robot-assisted) and transoral procedures. This article gives an overview of the clinically used alternative approaches in thyroid surgery. The desire for an optimal cosmetic result should not be prioritized over patient safety. Only a few alternative procedures (minimally invasive video-assisted thyroidectomy, transaxillary robot-assisted thyroidectomy) can currently be viewed as a useful addition to conventional thyroid surgery, even when in responsible, experienced hands for a selected group of patients. © 2021 Surgical Technology International™.
