Comparison Between the Axillary Bilateral-breast Approach (ABBA) and Bilateral Axillo-breast Approach (BABA) for Robotic Thyroidectomy
Comparison Between the Axillary Bilateral-breast Approach (ABBA) and Bilateral Axillo-breast Approach (BABA) for Robotic Thyroidectomy
The purpose of this study is to compare the therapeutic effects between the axillary
 bilateral-breast approach (ABBA) and bilateral axillo-breast approach (BABA) for robotic
 thyroidectomy.To explore the efficacy, safety, cosmetic results and clinical value by the two
 approaches.
Although several reports on operative outcomes of the robotic technique have appeared, no
 prospective trials comparing the clinical results of between the axillary bilateral-breast
 approach (ABBA) and bilateral axillo-breast approach (BABA) for robotic thyroidectomy have
 been described. The investigators therefore designed a prospective trial comparing outcomes,
 including surgical outcomes and patient satisfaction, between patients undergoing robotic and
 conventional open thyroidectomy.
Inclusion Criteria:

 1. the initial surgery

 than 1cm, no lateral neck lymph node metastasis

 3. the tumor is confined to the thyroid membrane, not invading trachea and recurrent
 laryngeal nerve

 4. intraoperative frozen section diagnosis of thyroid cancer

 5. the patient informed consent.

 Exclusion Criteria:

 1. high-frequency ultrasound preoperative tumor diameter greater than 1cm, or lateral
 neck lymph node metastasis in patients

 2. there had been a history of thyroid surgery or neck radiation therapy

 3. pregnant or lactating women

 4. with severe Hashimoto's thyroiditis, thyroid volume greater than II °

 5. coagulation disorders, hyperthyroidism or hypothyroidism patients
