Published data from large studies comparing operation outcomes between surgical techniques
| Study | Number of patients | Open thyroidectomy | MIVAT | SET | Robotic thyroidectomy | Operating time | Hospital stay | Complications | Postoperative pain | Quality of life# | Outcomes for P value ≤ 0.05 |
|---|---|---|---|---|---|---|---|---|---|---|---|

| Del Rio et al48 | 200 | √ | √ | – | – | – | – | √ | √ | – | The postoperative pain at 24 hours in MIVAT group was 1.033 ± 0.87, whereas in open group it was 1.915 ± 1.24 (P < 0.05) |
| Lombardi et al55 | 20 | √ | √ | – | – | √ | – | – | √ | √ | VAS at 48 hours was 10 ± 3 in MIVAT group, 8 ± 8 in Open group (P = 0.05). Cosmetic result (scale 0–10) was 9.3 ± 0.8 in MIVAT, 8.4 ± 0.1 in open group (P = 0.05) |
| El-Labban54 | 76 | √ | √ | – | – | √ | √ | √ | √ | √ | VAS at 24 hours was 2.6 ± 0.2 in MIVAT group, 3.4 ± 0.6 in open group (P < 0.001). Incision length (cm) was 3.2 ± 0.9 in MIVAT, 5.4 ± 0.7 in open group, and cosmetic result (scale 0–10) was 9.1 ± 0.5 in MIVAT, 4.9 ± 0.6 in open group (P < 0.001) |
| Lang and Chow71 | 46 | – | – | √ | √ | √ | √ | √ | √ | – | Operating time was higher in robotic group (P = 0.018). Pain score on operation day was higher in robotic group (P = 0.025) |

| Lee et al73 | 84 | √ | – | – | √ | √ | √ | √ | √ | √ | Operating time was 128.6 ± 36.3 for robotic group, 98 ± 22 for open group (P = 0.001). Patient complaints for hyper- or paresthesia in the neck after 3 months was 9.8% in the robotic group, 65.1% in the open group (P = 0.002). Greater satisfaction for cosmetic result was found in the robotic group (P < 0.0001) |
Notes: We present random studies that compare the operative outcomes between various surgical techniques in thyroid surgery.
