Background: The transient acute hypocalcemia (HypoCa) is the most prevalent complication after total thyroidectomy, detected primarily by subnormal intact parathyroid hormone (iPTH) and calcium levels. However, the need for calcium supplementation is ambiguous in patients who exhibit low iPTH with normal calcium levels. The aim of this study was to evaluate complementary predictors of HypoCa in this scenario., Methods: A retrospective cohort study with of 1597 consecutive patients undergoing total thyroidectomy, with or without neck dissection, from January 2014 to December 2018 at a single institution. Patients with an iPTH <12 pg/mL and a total calcium level ≥8 mg/dL in the first 8 h after surgery were included., Results: 1597 patients identified with low postoperative iPTH without overt calcium deficiency was diagnosed. The transient HypoCa in that specific subgroup was 509 (31.9%). Multivariate analysis indicated that HYPOCA was associated with bilateral level VI neck dissection and pre- to postoperative calcium reduction >38 pg/mL. To better illustrate the model, we plotted a nomogram with the variables selected for the final model., Conclusion: Total thyroidectomy patients who exhibit low postoperative iPTH levels without overt calcium deficiency should be considered for calcium replacement therapy when they a marked drop in iPTH postoperatively and underwent bilateral level VI neck dissection., (Copyright © 2021 Elsevier Inc.

Background: Since 2018, transoral endoscopic thyroidectomy vestibular approach (TOETVA) has emerged as a true scarless thyroid surgery. In this study, we explore early outcomes and learning curve of this new approach., Methods: A retrospective cohort including conventional thyroidectomies and TOETVAs performed in a cancer center was designed. Learning curve and early surgical outcomes of TOETVA were assessed and compared to conventional thyroidectomy., Results: A total of 56 TOETVAs and 745 conventional thyroid procedures were included. In the TOETVA group, we had a 14.4% total complication rate with no permanent vocal cord paresis or hypocalcemia. The mean surgical time dropped from 167 to 117 min (p = 0.0001) after the 15 first cases. Comparing to conventional procedures, we didn't find any significant difference in complications rate. Operative time was longer in the TOETVA group., Conclusions: In this study, TOETVA was safe and feasible, with a learning curve of 15 cases., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

In this note we describe the standard technical maneuver used in our department to protect the skin during thyroidectomy in order to get the best aesthetic result. We use surgical gloves to protect the skin during these operations to reduce the negative impact of thermal trauma and mechanical retractors and energy delivery devices at the edges of the skin incised. This practice is effective, inexpensive, rapid, reproducible and showed no complication in our experience of over 2,500 thyroidectomies.
