Vocal cord paralysis is the second most common congenital defect of the voice box, which accounts for about 10%-15% of congenital laryngeal disorders. It is an inability of one or both vocal cords to move properly. It is also called as a vocal fold paresis and it results from abnormal nerve input to the laryngeal muscles. This condition can occur at any age, from birth to advanced age, in males and females, due to a variety of causes. The cause of vocal fold paralysis indicates whether the disorder may resolve over time or it may be permanent. The major causes include inadvertent injury during surgery, a complication of endotracheal intubation, blunt neck or chest trauma, tumors of the skull base, neck, and chest, and viral infections.

Vocal fold movements are controlled by the brain through a specific nerve i.e. superior laryngeal nerve (SLN), and recurrent laryngeal nerve (RLN). SLN carries signals to the cricothyroid muscle, and RLN carries signals to different voice box muscles, which are responsible for opening vocal folds, closing the folds for vibration during voice use, and other activities. Diseases that result in inflammation of the vocal cords includes Wegener’s granulomatosis, gout, syphilis, sarcoidosis or polychondritis, and tuberculosis. Diabetes mellitus may also lead to a neuropathy resulting in vocal cord paralysis. Laryngoscopy is the most commonly adopted procedure for the diagnosis of vocal cord paralysis. According to a study published in Clinical and Experimental Otorhinolaryngology journal in 2017, it is found that electrical stimulation has emerged as a potential therapeutic technique to measure peripheral nerve injury. It is also stated that electrical stimulation may promote the specificity of reinnervation of denervated laryngeal muscles.
Notably, rising technological advancements is the key factor driving the vocal cord paralysis market. In the recent years, various new endoscopic technologies such as CT colonography, Narrow Band Imaging, Endoscopic Mucosal Resection (EMR), Capsule Endoscopy, Endoscopic Ultrasound (EUS), Mucosal Ablation Therapies, microendoscopy, etc., have increased accuracy in diagnosis and treatment to a great extent.
Various other push factors such as increasing awareness among people, increasing government assistance, improving regulatory framework, and rising funding and reimbursement continuously contributing to the growth of the global vocal cord paralysis market.
Despite these drivers, there are some issues associated with vocal cord paralysis market. Some of the challenges in research and development are lack of skilled physicians, and poor healthcare system in low and middle-income countries may hinder the growth of the market to an extent.
It is estimated that the vocal cord paralysis market is expected to grow at a CAGR 6.4% during the forecast period of 2017-2023.
