Abstract
IntroductionOdynophonia is defined as pain during phonation. Referring to frequent discomfort that professionals of the voice experience. It is estimated that those who suffer this symptom will present high perilaryngeal sensitivity; however, this situation has not been proved. ObjectiveThe main objective of this investigation is to compare the perilaryngeal tissue pressure thresholds between patients with odynophonia and asymptomatic individuals. Material and methodA total of 42 female voice professionals and students with related careers were included. From this total, 2groups were extracted, the first (G1) was composed of 21 asymptomatic individuals (without pain during phonation), aged 21.5±1.94 years. Meanwhile, the second group (G2) comprised 21 subjects who presented pain during phonation with a mean age of 25.1±2.27 years. The perilaryngeal tissue pressure thresholds of both groups were evaluated through algometry. ResultsThe pressure threshold in those suffering from odynophonia fluctuated between 300 and 2,000 grams, while that of asymptomatic individuals were between 1,000 to 2,700 grams. ConclusionPerilaryngeal tissue pressure thresholds were significantly lower in the patients suffering odynophonia in comparison with those who were asymptomatic.
