This protocol presents the procedure for conducting thyroidectomy using the gasless endoscopic thyroidectomy trans-axillary approach (GETTA).
For patients with early, low-risk papillary thyroid carcinoma, an increasing number are opting for endoscopic thyroid surgery due to its ability to achieve favorable therapeutic outcomes while maintaining excellent cosmetic results. Among the available endoscopic procedures, the Gasless Endoscopic Thyroidectomy Trans-axillary Approach (GETTA) has gained popularity among surgeons. This is attributed to its straightforward cavity construction, spacious operating area, precise visual field exposure, and manageable learning curve. However, few studies have provided detailed descriptions of the specific surgical steps involved in GETTA. Drawing from a synthesis of existing literature and our own clinical expertise, we present a comprehensive outline of the GETTA procedure. This process can be categorized into five distinct stages: positioning and incision planning; establishment of surgical cavities; identification and protection of the recurrent laryngeal nerve, inferior parathyroid gland, and central neck dissection; localization and preservation of the superior laryngeal nerve, superior parathyroid gland, and dissection of the thyroid's superior pole; transection of the thyroid isthmus followed by en bloc resection of the thyroid gland and central neck lymph nodes. The five-step approach of GETTA is easy to learn and can be adapted for resecting both benign and malignant thyroid and parathyroid diseases.
The recent increase in the incidence of papillary thyroid microcarcinoma (PTMC)1,2, predominantly affecting young women, necessitates advancements in surgical techniques that offer both medical effectiveness and aesthetic sensitivity3,4. The primary goal of the Gasless Endoscopic Thyroidectomy Trans-axillary Approach (GETTA), introduced by Chung in 20045, is to provide an optimal surgical method that marries these two needs.
GETTA was developed as an answer to the drawbacks of traditional open surgery, such as noticeable scars leading to patients' self-consciousness and potential negative impact on their work and social activities. Endoscopic thyroid surgery has been gradually applied in the treatment of benign and malignant thyroid diseases3,4, offering a less invasive alternative to open surgery. Yet, the innovation of GETTA lies in its unique gasless approach. The GETTA procedure holds several advantages over alternative techniques. It establishes the cavity through the natural folds of the axilla, rendering the incision hidden and yielding superior postoperative cosmetic results6. Moreover, GETTA omits the need for CO2 gas inflation during the operation, thereby averting complications related to CO2 gas. Furthermore, this approach leaves the anterior neck flap intact, which protects the function of the anterior cervical region post-surgery and prevents postoperative swallowing skin-tracheal linkage6,7.
The technique is situated within the wider body of literature concerning endoscopic thyroid surgery. While there are ample research reports on the transoral and breast approach of endoscopic thyroid surgery8,9, non-inflatable thyroid surgery remains underreported10,11. Consequently, this method constitutes a significant contribution to this field, providing a comprehensive protocol for the GETTA procedure.
For readers contemplating the application of this method, it is most suitable for early-stage, low-risk papillary thyroid carcinoma patients who desire minimal scarring post-surgery. However, the success of this technique depends on the practitioner's proficiency in endoscopic procedures due to its spatial constraints. As such, the method may not be appropriate for practitioners without advanced endoscopic skills or those in medical centers with limited access to the necessary equipment.
This article aims to bolster the understanding of the GETTA procedure, offering insights into its application, and hopefully promoting its adoption in more medical centers. The benefits of GETTA extend beyond medical effectiveness, meeting patients' desire for less invasive surgery with favorable cosmetic results.
This study was conducted in strict accordance with the ethical principles outlined in the Declaration of Helsinki and adhered to the guidelines established by our institution's Human Research Ethics Committee. The research protocol underwent a thorough review and received approval from the Ethics Committee of West China Hospital of Sichuan University. All participating patients provided written informed consent before their involvement in the study, and stringent measures were taken to ensure the privacy and confidentiality of their data throughout the research process. Patients with benign thyroid nodules, follicular neoplasms, or papillary microcarcinomas, with a tumor size of less than 2 cm, and the absence of lymph node metastasis, were included in the present study. On the other hand, patients with advanced thyroid cancer, tumors larger than 2 cm, evidence of lymph node metastasis, a history of neck surgery that might have resulted in anatomical distortions, or severe comorbidities were excluded from this study.

In this study, a cohort of 200 female patients, all with a mean age of 36 years (SD = 4.52; ranging from 20 to 59 years), underwent the Gasless Endoscopic Thyroidectomy Trans-axillary Approach (GETTA) (Table 1). The patients had an average Body Mass Index (BMI) of 22.79 kg/m2 (SD = 4.52; range = 18.27-27.31). The sonogram indicated an average tumor size of 7.09 mm (SD = 3.84). All patients were fully informed of the surgical options available and subsequently chose GETTA. Of the total, 54 (27%...
The Gasless Endoscopic Thyroidectomy Trans-axillary Approach (GETTA) is a novel surgical method that addresses the rising incidence of Papillary Thyroid Microcarcinoma (PTMC) while yielding aesthetically pleasing outcomes14,15,16. Nevertheless, this technique requires a deep understanding of key operational steps17. Before commencing the actual surgery, surgeons are expected to familiarize themselves with...
