According to a detailed report published Market Research Future (MRFR), by the Global Vocal Cord
Paralysis Market is expected to value at USD 2920.2 Million by 2024, growing at a 3.8% CAGR from 2018 to 2023.
Caption: Voice disorders can result from a number of problems affecting the vocal cords
, larynx (voice box) and other structures in the throat and elsewhere.
After the arytenoid release procedure was performed in the left side, the mucous membrane of vocal cord
showed pliable compared to the opposite cord and eligible for an exoeSL procedure.
are histologically composed of surface epithelium, lamina propria, and muscular layers.
To date, only five cases of vocal cord
paralysis following spinal or epidural anaesthesia have been documented to our knowledge.
paralysis (VCP) can result from processes that alter normal function of recurrent laryngeal nerve or vagus nerve.
hematoma generally appears on the left vocal fold; this is typically related to right-sided insertion of the orotracheal tube and left-handed hold of the laryngoscope (10).
Other causes of VCP like traumatic or forceps delivery, mediastinal surgery, and ligation of patent ductus arteriosus, brainstem anomalies, and intracranial bleeding were not present in our case, and hence the diagnosis of idiopathic congenital bilateral vocal cord
paresis was made.
We also hypothesized that in patients with bilateral vocal cord
paralysis the quality of voice and speech is significantly lower compared to the healthy subjects.
Flexible laryngoscopy revealed large bilateral vocal cord
polyps causing almost complete airway obstruction.
A fibronasolaryngoscopy showed arythenoidal and vocal cord
edema (ventricular bands) with incomplete left vocal cord
There were 22 cases (44%) of polypoid lesions, 16 cases (32%) of vocal nodules, single case (2%) of true cyst of vocal cord
, 3 cases (6%) of Reinke's edema, 4 cases of cysts, and a single case each of posttraumatic granuloma, laryngopyocele, papilloma, hemangioma, and laryngeal sporidiosis.
