Summary
Identifying the recurrent laryngeal nerve (RLN) during thyroid surgery is crucial. This study details RLN anatomy, including its relationship with the inferior thyroid artery, aiding safe surgical dissection.
Area of Science:
- Anatomy
- Surgical Procedures
- Nerve Identification
Context:
- Thyroid surgery carries risks of recurrent laryngeal nerve (RLN) injury.
- Understanding RLN's anatomical variations is vital for surgical safety.
- Preoperative and intraoperative identification strategies are key.
Purpose:
- To investigate the anatomical characteristics of the recurrent laryngeal nerve (RLN).
- To define optimal dissecting approaches for the RLN during thyroidectomy.
- To analyze the relationship between the RLN and the inferior thyroid artery.
Summary:
- A retrospective review of 63 recurrent laryngeal nerves (RLNs) in 56 thyroid surgery patients was performed.
- Nerve bifurcation was observed in 48 RLNs.
- The RLN's position relative to the inferior thyroid artery varied: 29 deep, 19 superficial, and 8 between branches; the artery was absent in 7 cases.
Impact:
- Provides critical anatomical data for thyroid surgeons.
- Enhances understanding of recurrent laryngeal nerve (RLN) variations.
- Contributes to reducing vocal cord paralysis after thyroid surgery.
