RLN

Full Definition

The recurrent laryngeal nerve, a branch of the vagus nerve that innervates most of the intrinsic muscles of the larynx. This nerve is at significant risk during thyroid and parathyroid surgery due to its close anatomical relationship to these glands. Injury can result in vocal cord paralysis and voice changes. Medical editors must understand the significance of RLN monitoring and preservation techniques in surgical documentation.
