The effect of robot-assisted transaxillary thyroidectomy (RATT) on body image is better than the conventional approach with cervicotomy: a preliminary report

Background Cosmetic satisfaction is not only based on the patient's perception of the scar itself but is also related to body image self-evaluation. Cosmetic superiority of Robot-assisted transaxillary thyroidectomy (RATT) over conventional thyroidectomy (CT) has not yet been clearly demonstrated. Aim of our study was to compare body image in patients undergoing CT versus RATT. Methods The study included 160 (80 CT and 80 RATT) patients undergoing thyroidectomy between August 2014 and March 2018 at the Endocrine Surgery Department. The inclusion criteria were age 18 to < 60 years, female sex, thyroid volume < 30 mL, and nodule diameter < 5 cm. Scar length, operative time, and complications were analyzed. The body image questionnaire (BIQ) was used 3 months postoperatively. The Student t test was used for statistical analysis. Results Age was lower in RATT group (38.2 vs 41.4 years) (P < 0.0001). The nodule diameter was larger in RATT group (27.1 vs 23.1 mm) (P = 0.028). Operative time was longer in RATT group (93.7 vs 47.6 min) (P < 0.0001). The scar was longer in RATT group (59.9 vs 37.7 mm) (P < 0.0001). The groups had similar complication rates. BIQ showed that RATT patients answered more favorably to question 2, "Do you feel the operation has damaged your body?" (P = 0.042) and to question 3, "Do you feel less attractive as a result of your treatment?" (P = 0.024). Also self-global satisfaction was better in RATT group (P = 0.019). Conclusions In our experience, RATT has a significantly better impact on body image than the conventional approach.
