Due to the complex and controversial nature of this condition, epidemiological (incidence) reports vary significantly and more research in this area is needed. Instead of reporting the incidence of this condition within the general population, most studies are conducted within specialized voice disorder clinics. In such a setting, one study found that approximately 26% of patients are diagnosed with paralysis or<unk>  of the vocal folds. Yet, incidence rates as high as 80% for vocal fold<unk>  have been reported elsewhere. Yet another source reported only 71 cases of vocal fold<unk>  over 7 years. Incidence rates of vocal fold<unk>  after undergoing thyroid surgery have been reported between 0.3% and 13.2%, whereas these incidence rates are between 2% and 21.6% after undergoing spinal surgery.
