Vocal cord paresis, also known as recurrent laryngeal nerve paralysis or vocal fold paralysis, is an injury to one or both recurrent laryngeal nerves (RLNs), which control all intrinsic muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing.
Damage to these nerves results in vocal cord paralysis - the reduced mobility and inability to adduct one or both vocal cords. Many cases of vocal cord paralysis result from trauma during surgery. [2] Symptoms include hoarseness of voice, difficulty projecting, difficulty swallowing, and throat pain. [citation needed]
The recurrent laryngeal nerves supply sensation to the larynx below the vocal cords, give cardiac branches to the deep cardiac plexus, and branch to the trachea, esophagus and the inferior constrictor muscles. The posterior cricoarytenoid muscles, the only muscles that can open the vocal folds, are innervated by this nerve.
Unilateral vocal cord paralysis where one vocal cord out of the two is paralysed. Symptomatic glottic insufficiency (dysphonia, aspiration) which leads to incomplete glottic closure which in turn results in failure to produce proper sound. Age-related vocal fold atrophy leading to glottic insufficiency. [4]

Vocal cord dysfunction (VCD) is a condition affecting the vocal cords. [1] It is characterized by abnormal closure of the vocal folds, which can result in significant difficulties and distress during breathing, particularly during inhalation. [1] Due to the similarity in symptoms, VCD attacks are often mistaken for asthma attacks or laryngospasms.
