“…More up-to-date studies have shown that it is not possible to diagnose the lesion site based solely on vocal fold position, and that these factors are not highly correlatable 30 , 31 . In our study, the paramedian and intermediate positions were the ones most commonly found ( Table 1 ), in agreement with the results from other studies 2 , 24 . Other authors 25 , 32 found results which differ from the ones we found, since they argued that the median and paramedian positions were the most frequently found in their sample.…”

“…As far as the age range is concerned, we noticed a predominance of the elderly population, with a mean of 60.7 years ( Table 1 ). According to the literature studied, the mean age of paralysis onset is between 55 and 64 years 2 , 5 . Thus, it is among the elderly population that we find the greatest prevalence of vocal fold paralyses, and it is associated with the greater incidence of progressive neurologic disorders and non-laryngeal malignant diseases in this group.…”

“…The precise incidence of vocal fold paralysis in the Brazilian Population is still unknown 1 , 2 . Notwithstanding, most vocal fold paralysis cases are among the elderly, and this is associated with a higher incidence of progressive neurological and non-laryngeal malignant diseases in this age range 2 . Vocal fold paralysis onset mean age is between 55 and 64 years 3 , 4 .…”

The paralyzed vocal fold positioning and the degree of dysphonia are important inputs when one is deciding upon treatment options for unilateral vocal fold paralysis (UVFP).Objective: To check voice characteristics and paralyzed vocal fold position in men with UVFP. Materials and Methods:This is a retrospective historical cross-sectional cohort study, with data from 24 men with UVFP with mean age of 60.7 years, submitted to voice assessment by three speech therapists and three ENT physicians used laryngeal images to classify the position of the paralyzed vocal fold. Results:The paralyzed vocal fold was found in the paramedian position in 45.83% of the cases; in the intermediary position in 25%; lateral in 20.83%, and it was in the median position in 4.16%; the dysphonia resulting from the UVFP was characterized by moderate hoarseness, roughness and stress in the voice; breathiness (most had severe breathiness); weakness and instability(mostly mild); the position of the paralyzed vocal fold had a significant influence on the general degree of vocal deviation. Conclusion:The general degree of dysphonia is associated with the paralyzed vocal fold position; dysphonia is characterized by hoarseness, breathiness, roughness and stress of moderate to severe levels.

“…The management of the etiological factors, causing VCP, alone may sometimes be the complete treatment for VCP. The imaging modalities like computed tomography (CT) scan, magnetic resonance imaging (MRI) and modified barium swallow (MBS), in addition to consultation with various other specialties such as neurology, gastroenterology, pulmonology, cardio vascular surgery, or spine surgery are required most of the times to ascertain the main cause responsible for VCP [1,5,[11][12][13].…”

Background The study was performed to evaluate the changing trends in etiology and presenting features of vocal cord paralysis (VCP) from March 1998 to March 2020. Methods Patient’s record collected from hospital database and divided into two groups, from March 1998 to March 2009 and from April 2009 to March 2020, to evaluate the changing trends in etiology and presenting features. Results Total of 711 VCP patients, 80.3% with unilateral (UVCP) and 19.7% with bilateral vocal cord paralysis (BVCP) included. The commonest etiology was non-surgical (57.1%) for UVCP and surgical (55.7%) for BVCP. The commonest surgical etiology was thyroid and parathyroid surgery for both UVCP (16.6%) and BVCP (38.5%). The commonest non-surgical etiology was idiopathic for UVCP (23.1%) and malignancies for BVCP (13.6%). There was increase in surgical etiology for both UVCP (39.3 to 45.3%) and BVCP (51.2 to 57.7%), and decrease in non-surgical etiology for both UVCP (60.7 to 54.6%) and BVCP (48.8 to 42.3%). The change in voice was most common presenting features for both UVCP (69.2%) and BVCP (92.8%). The frequency of the presenting features was comparable, with decrease in the duration of symptom onset over the time period. Conclusion The most common etiology for UVCP was idiopathic, and for BVCP was thyroid and parathyroid surgery. For both, UVCP and BVCP there was increasing trend for surgical and decreasing trend for non-surgical etiology. The change in voice was the most common presenting complain, with decrease in duration of symptom onset over time period.
