A Novel Contralateral Axillo-Bilateral-Breast Approach for Endoscopic Thyroid Surgery
July 28th, 2026
This protocol presents a novel contralateral axillo-bilateral-breast approach for endoscopic thyroidectomy that optimizes surgical positioning and operative space while achieving excellent cosmetic outcomes.
Overview
This article presents a novel endoscopic thyroidectomy technique known as the contralateral axillo-bilateral-breast approach (CABBA-ET). The protocol aims to address cosmetic concerns associated with traditional open thyroidectomy by utilizing trans-areolar and axillary incisions, resulting in concealed scars and improved patient satisfaction. The technique demonstrates operative safety and efficacy comparable to conventional methods, with superior cosmetic outcomes in a cohort of 130 patients.
Key Study Components
Area of Science
- Endocrine surgery
- Minimally invasive surgery
- Surgical oncology
Background
- Thyroid cancer incidence is rising globally.
- Open thyroidectomy often leaves visible neck scars, leading to cosmetic concerns.
- Minimally invasive and endoscopic approaches are being developed to improve cosmetic outcomes.
- Existing endoscopic techniques may have limitations in patient positioning and scar concealment.
Purpose of Study
- To describe and demonstrate the CABBA-ET technique for thyroidectomy.
- To evaluate the safety, feasibility, and cosmetic outcomes of this approach.
- To provide a detailed, replicable protocol for surgeons.
Methods Used
- Patient placed in supine position without leg separation.
- Trans-areolar and axillary incisions for endoscopic access.
- Subcutaneous space created and dissection performed above the platysma.
- Use of ultrasonic scalpel, nanocarbon tracer for lymph node mapping, and nerve monitoring.
- Preservation of parathyroid glands and recurrent laryngeal nerve.
- Postoperative assessment of drainage, complications, and cosmetic satisfaction.
Main Results
- Mean operative time: 95 minutes; mean hospital stay: 2.3 days.
- No cases of postoperative hemorrhage requiring re-operation.
- Transient recurrent laryngeal nerve palsy in three patients; no permanent complications.
- No chest wall skin burns or CO2 emphysema observed.
- Significantly higher cosmetic satisfaction scores compared to conventional thyroidectomy.
Conclusions
- CABBA-ET is a safe and feasible alternative to conventional thyroidectomy for selected patients.
- The approach offers superior cosmetic outcomes with concealed scars.
- The protocol is replicable and may expand access to scar-free thyroid surgery worldwide.
Frequently Asked Questions
Executive Industry Relevance
Minimally invasive surgical innovations like the contralateral axillo-bilateral-breast approach (CABBA-ET) for thyroidectomy address the growing demand for procedures that minimize visible scarring and postoperative complications. For biopharma R&D, such techniques enable more precise anatomical access, facilitate nerve and gland preservation, and support the development of advanced perioperative monitoring tools.
