          Abstract

          OBJETIVO: Verificar via fonação inspiratória, se parâmetros visuais e perceptivo-auditivos relacionam-se com a hipótese diagnóstica de nódulos e cistos. MÉTODOS: Foram analisadas 21 videolaringoestroboscopias de pacientes com nódulos (n=6) e cistos (n=15), média de idade de 35 anos (13-68 anos), 18 mulheres e três homens. Dados visuais e perceptivo-auditivos dos exames, avaliados na fonação expiratória e inspiratória, foram apresentados aleatoriamente, comparados e registrados em protocolo específico, por fonoaudiólogo especialista em voz, desconhecedor da hipótese diagnóstica. RESULTADOS: Nos nódulos, a vogal sustentada evidenciou maior ocorrência de desvios vocais (66,7%), do que a fala encadeada (33,3%); a vogal sustentada apresentou-se soprosa (100%) e a fala encadeada, adaptada (66,7%). Nos cistos, o desvio foi mais frequente na vogal sustentada (46,7%) do que na fala encadeada (40%); a vogal sustentada apresentou tanto componente rugoso (40%) como soproso (33,3%). Todos os nódulos foram simétricos em localização (100%) e a maioria foi simétrica em tamanho, em ambas as fonações (66,7% e 75%, respectivamente). Os cistos tenderam à simetria em localização (75%), mas não foram simétricos em tamanho (100%). O ligamento vocal foi mais visível nos cistos (53,3% e 80%) do que nos nódulos (33,3% e 66,7%), respectivamente, na fonação expiratória e inspiratória, e mais evidente durante fonação inspiratória. Quando visível nos nódulos, o ligamento vocal foi sempre bilateral (100%). CONCLUSÃO: A fonação inspiratória revelou características diferenciais para nódulos e cistos; a análise perceptivo-auditiva ofereceu informação adicional na caracterização das lesões.

          PURPOSE: To verify, using inspiratory phonation, whether visual and auditory-perceptual parameters correlate with the diagnostic hypothesis of nodules and cysts. METHODS: Twenty one videolaryngostroboscopies of patients with suspected nodules (n=6) and cysts (n=15) were analyzed. Subjects were 18 women and three men, with mean age of 35 years (13-68 years). Visual and auditory data, obtained from expiratory and inspiratory phonation, were randomly presented, compared and registered in a specific protocol by a trained speech-language pathologist, to whom diagnostic hypotheses were omitted. RESULTS: In nodule cases, sustained vowel showed higher occurrence of vocal deviation (66.7%), when compared to speech (33.3%); sustained vowel had a breathy quality (100%) and speech was adapted (66.7%). In cyst cases, deviation was also more frequent during sustained vowel (46.7%) than during speech (40%); sustained vowel presented both roughness (40%) and breathiness (33.3%). All nodules were symmetric in location (100%), and most were also symmetric in size, in both types of phonation (66.7% and 75% respectively). Cysts tended to be symmetric in location (75%), but asymmetric in size (100%). The vocal ligament was more visible in cysts (53.3% and 80%) than in nodules (33.3% and 66.7%), in expiratory and inspiratory phonation respectively, and this structure was more evident during inspiratory phonation. When visible in nodules, the vocal ligament was bilateral (100%). CONCLUSION: Inspiratory phonation revealed differential characteristics for nodules and cysts diagnoses; the auditory-perceptual evaluation added information to characterize both lesions.

            Vocal fold masses.

            Vocal fold masses are often complex in nature and can have a devastating result on the professional voice. These lesions are usually multifactorial with synergistic contributions over time from voice use demands and technique, medical conditions, medications, and the environment. General categories of benign vocal fold masses in professional voice include nodules, polyps, and cysts, but other pathology should be considered, such as reactive lesions, intracordal scarring, feeding varices, and reparative granuloma. A perspective on these issues is essential for proper diagnosis and management. Video procedures for nodule and polyp surgery accompany this content online.
