ABSTRACT
Background
New approaches for robotic-assisted thyroidectomy were recently described. The purpose of this study was to present the report of our initial experience using a retroauricular approach for thyroid and parathyroid surgeries.
Methods
This is a prospective study that was conducted under institutional review board approval and all surgeries were performed by a single surgeon at a North American academic institution. Some patients underwent an additional concomitant neck lift surgery in addition to the thyroid surgery. Some cases were performed without the use of the robot and they have been evaluated compared with the robotic cases. Clinical characteristics, total operative time, blood loss, surgical outcome, and length of hospital stay were evaluated.
Results
Forty cases representing thirty-eight female patients were included in this study, which includes 37 thyroid lobectomies and 3 parathyroid surgeries. Mean age was 44 ± 13 years, and mean body mass index (BMI) was 26.9 ± 5.31. Mean thyroid nodule size was 2.01 ± 0.94 cm. All cases were completed successfully via a single retroauricular incision. There was no conversion to an open approach. Six of 38 patients underwent additional neck lift surgery with a mean total operative time of 189 ± 45 minutes. The mean operative time for the remaining 34 patients who underwent retroauricular robotic-assisted hemithyroidectomy without neck lift surgery was 156 ± 39 minutes. Five patients underwent an endoscopic, retroauricular approach to the thyroid and parathyroid without using the robot. Two of 38 patients developed postoperative hematoma, in whom one of them needed a surgical evacuation. There were no cases of permanent vocal cord paralysis or permanent hypoparathyroidism. However, 2 patients developed transient hoarseness, which resolved 9 weeks and 10 weeks postoperatively, respectively. Mean blood loss was 19.0 ± 30.93 mL. Twenty-one patients were discharged on the same day of surgery, 17 patients were discharged after an overnight stay, and the remaining 2 patients were discharged after 2 days.
Conclusion
Single-incision retroauricular robotic hemithyroidectomy and parathyroidectomy can be safe and feasible and concomitant neck lift surgery can be offered in a select group of patients. In addition, the nonrobotic retroauricular approach can be performed safely; however, future studies are warranted to further evaluate the benefits and limitations of this novel robotic retroauricular surgical approach.
