Abstract
ObjectivesResonance characteristics can change due to alterations in the shape of the vocal tract in patients with epiglottic cysts. This study aimed to analyze the resonance characteristics before and after the surgical excision of epiglottic cysts. MethodsTwelve male patients with epiglottic cysts were enrolled in this study. We analyzed the first and second formants (F1 and F2) in vowels /a/, /e/, /i/, /o/, and /u/, vowel space area (VSA), vowel articulatory index (VAI), and formant centralization ratio (FCR). We measured these parameters before and after the surgical excision of epiglottic cysts. ResultsThere was a significant increase in the F1 values of /a/, VSA, and VAI, and a significant decrease in the value of FCR after the surgery. ConclusionWe confirmed the change in the resonance characteristics in patients with epiglottic cysts. It is considered that further studies on epiglottic cysts and resonance changes are needed in the future.
