Background:
The transoral endoscopic vestibular approach (TOETVA) for thyroidectomy is gaining popularity (Russell et al. in Thyroid 28(7):825-829, 2018; Le et al. in Surg Laparosc Endosc Percutan Tech 30(3):209-213, 2020; Liao et al. in Laryngoscope 130(6):1603-1608, 2020). TOETVA has been utilized successfully in performing thyroidectomy, parathyroidectomy, and neck dissection, via both endoscopic and robotic techniques (Razavi et al. in Head Neck 40(10):2246-2253, 2018; Otolaryngol Head Neck Surg 159(4):625-629, 2018; Ngo et al. in J ENT, 2020. https://doi.org/10.1177/0145561320943358 ; Ann Surg Oncol 28(5):2766, 2021). In this video, we show bilateral central neck dissection via transoral approach in papillary thyroid carcinoma.
Patient And Methods:
A 37-year-old female with no significant medical history was diagnosed pT3bN0M0 intraoperatively with the tumor having slightly invaded the strap muscle. Thus, we decided to perform total thyroidectomy with bilateral central neck dissection via transoral approach.
Methods:
Prelaryngeal dissection: in the prelaryngeal compartment, soft tissue containing these lymph nodes was intimately associated with the pyramidal lobe. Right paratracheal dissection: fibrofatty tissue was dissected off the prevertebral fascia and the trachea with preservation of right parathyroid glands. Pretracheal lymph nodes were removed with paratracheal dissection. Left paratracheal dissection: the lymphatic tissue was then dissected off the prevertebral and esophageal musculature and the trachea after identifying the left parathyroid glands. Finally, bilateral central neck dissection was finished with preservation of the nerve and parathyroid glands.
Results:
The operation was completed successfully without conversion to open surgery. The operative time for central neck dissection was 20 min. There were nine harvested lymph nodes in the central compartments, while there were two metastatic lymph nodes of papillary thyroid carcinoma with 3 × 3 mm maximal dimension. There were no major postoperative complications.
Conclusion:
Central neck dissection via TOETVA is a safe and feasible method in selected patients.
