Brief Summary
This study evaluates a thyroid-function-preserving alternative to routine total thyroidectomy for bilateral papillary thyroid carcinoma (PTC). Eligible adults undergo remote-access gas-less axillo-breast endoscopic hemithyroidectomy with level VI dissection on the dominant side, followed by ultrasound-guided radiofrequency ablation (RFA) of a ≤7 mm contralateral focus during the same anesthesia. Outcomes include structural-recurrence-free survival, endocrine-function preservation, safety, and quality of life over 24 months.

Study Arms (1)
Hybrid Endoscopic Hemithyroidectomy + Same-Session Contralateral RFA
EXPERIMENTALRemote-access gas-less axillo-breast endoscopic hemithyroidectomy with level VI central-neck dissection on the dominant lobe, immediately followed-under the same anesthesia-by ultrasound-guided radiofrequency ablation (17-G, 0.7 cm active tip, 40 W, moving-shot technique) of a ≤ 7 mm contralateral papillary thyroid microcarcinoma.
Interventions
Gas-less axillo-breast approach (trans-axillary + peri-areolar), carbon-dioxide-free working space, removing dominant thyroid lobe plus level VI lymph nodes; intra-operative neuromonitoring used throughout.
17-gauge internally-cooled electrode, 0.7 cm active tip, power 40 W; moving-shot technique under real-time ultrasound until hyperechoic halo fully covers ≤ 7 mm papillary microcarcinoma ≥ 2 mm from posterior capsule; same anesthesia session as surgery.
Eligibility Criteria
You may qualify if:
- Age 18-65 years.
- Dominant-side PTC ≤1.5 cm suitable for endoscopic resection.
- Contralateral nodule ≤7 mm located ≥2 mm from posterior capsule.
- No radiologic lymph-node metastasis on contralateral side.
- Written informed consent.
You may not qualify if:
- Extrathyroidal extension, gross nodal or distant metastasis.
- Prior neck surgery, prior RFA/ethanol injection, or neck irradiation.
- Pregnancy or lactation.
- Serious comorbidities precluding anesthesia or follow-up.
