Unilateral Vocal Fold Paralysis Heather Newberg Jacksonville University INTRODUCTION Unilateral vocal fold paralysis (UVFP) is the complete immobility of one vocal fold. According to Sapienza and Ruddy (2013), “90% of vocal fold paralysis that occurs is unilateral and caused by damage to the peripheral nervous system” (p. 189). Vocal fold paralysis is typically considered a symptom of a disease or neurologic disruption. In one study, it was found that vocal fold paralysis was caused by surgical

called vocal fold nodules (Phillippe H. al., et 2009). While looking at vocal fold nodules, one may notice tiny bilateral lesions. The SLP may also discover that vocal fold nodules appear as proportional mass lesions. The history of vocal fold nodules dates back to 1866, when the pathology was first discovered by Turk (Simpson B al., et 2008). “Vocal fold nodules occur more frequently in children and women (Simpson B al., et 2008).” “Another interesting fact is that 95% of the vocal fold nodule cases

Introduction Vocal fold polyps are common in the general population. They affect the vibratory vocal fold function resulting in significant dysphonia which are often surgically correctable. They are confined to the superficial lamina propria (SLP) of the vocal folds . Nowadays , phonomicrosurgery is the most common treatment of vocal fold polyps , and became a new standard of care to remove pathology in these cases without scar formation . The term phonomicrosurgery was introduced

Introduction: The larynx is the part of the respiratory system that contains the vocal folds, and is responsible for the creation of sound. The larynx sits on top of the trachea or windpipe, which allows for air to pass to and from the lungs when the body inhales and exhales. Positioned at the upper opening of the larynx are two mucous membranes that make up the vocal folds or glottis. The vocal folds consist of twin flaps of cartilage, on average two to four centimeters long, in the shape of a “V”

2007) Jitter values above this level indicate that the vocal folds are vibrating in a way that

sound that once you hear once, you will not forget it again. One commonly known type of overtone sing is Polyphonic overtone singing, a technique which produces two notes in perfect harmony. The lower of the two is generated by the vibrations of vocal folds in the larynx which is the same process for everyday speech. This sound wave is a fundamental frequency, as it has the longest wavelength that will fit inside the resonant cavity formed by the speaker’s mouth and throat. Produced alongside this

sinusitis) were excluded due to the well-known and documented harmful effects of these disorders on the voice quality.In our subjects, it was found that jitter, PPQ and phonatory resistance increase with the decrease in the pulmonary function. These vocal functions increased in abnormal voice quality and considered objective indications of dysphonia. The phonatory resistance increased with the decrease in the pulmonary function. Our subjects did not receive medication

flowing through the respiratory system and keep foreign objects out. Additionally, children’s vocal folds have an average fundamental frequency, or vocal fold vibration, of 250 Hz per second. However, the larynx also has the nonbiological function of acting as a vibratory source for speech. This is a complex system and so produces a lot of variety in speech, particularly between men and women. Therefore, vocal production becomes indicative of how a person is perceived, partially based on societal assumptions

used to target increasing vocal loudness and amplitude, particularly in individuals with Parkinson’s Disease. The Lee Silverman Voice Treatment (LSVT) “is an intensive, 1-month speech therapy regimen that trains dysarthric individuals with Parkinson’s Disease to speak in a louder voice while self-monitoring the effort it takes to produce such a voice” (Sapir, Spielman, Ramig, Story, & Fox, 2007). The treatment focus is to improve the individual's voice quality and vocal function. Although the treatment
