RESUMO
INTRODUCTION: The Voice Handicap Index has been shown to be a valid instrument for assessing self-perceived handicap associated with dysphonia. OBJECTIVES: To test the psychometric properties of the Spanish version of the VHI-30 (Voice Handicap Index) and its shortened version VHI-10. SUBJECTS AND METHOD: The original VHI-30 was translated into Spanish and was completed by 232 dysphonic patients and 38 non-dysphonic individuals. Prospective instrument validation was performed. RESULTS: Results showed high test-retest reliability, and high item-total correlation for both Spanish VHI-30 and VHI-10. Internal consistency demonstrated a Cronbach's alpha of 0.93 and 0.86, respectively, and a significant correlation was found between the VHI scores and the patients' self-rated dysphonic severity. CONCLUSIONS: The present study supports the use of Spanish versions of VHI-30 and VHI-10 because of their validity and reliability.

Introducción y objetivos: El índice de incapacidad vocal (Voice Handicap Index) es un instrumento válido para la valoración del menoscabo asociado a la disfonía que percibe el paciente. El objetivo es valorar las propiedades psicométricas de la versión castellana del VHI-30 y su versión abreviada VHI-10. Sujetos y método: El VHI-30 original se tradujo al idioma español y lo contestaron 232 pacientes con disfonía y 38 sujetos sanos. Se realizó una validación prospectiva del instrumento. Resultados: Se encuentra una alta fiabilidad test-retest y altas correlaciones ítem-total tanto para el VHI-30 como para el VHI-10. La coherencia interna demuestra valores alfa de Cronbach de 0,93 y 0,86 respectivamente, y se encontró una correlación significativa entre las puntuaciones del VHI y la valoración de los pacientes de la severidad de su disfonía. Conclusiones: El presente estudio apoya el uso de las versiones en español del VHI-30 y del VHI-10 por su validez y fiabilidad

Sulcus vocalis, vergetures, mucosal bridges, and cysts as intracordal lesions constitute a group of great diagnostic difficulty. We present 6 patients in whom microlaryngoscopy was the final diagnostic step in the evaluation of a lesion not recognized in the initial evaluation. The criteria selected were as follows: Severe GRABS. Stroboscopic parameters: glottal chink without mass lesion, asymmetry of amplitude, and irregularity of vibration, or when discrepancy between examination and quality of the voice exists. Acoustic and aerodynamic measures that demonstrate severe dysphonia. High scores on the Voice Handicap Index. We recommend carrying out a diagnostic microlaryngoscopy examination where the cause of dysphonia is unclear.

Los sulcus vocalis, vergetures, puentes mucosos y quistes son lesiones intracordales que constituyen un grupo de lesiones de difícil diagnóstico. Presentamos a 6 pacientes en los que la microlaringoscopia fue el paso diagnóstico definitivo en la evaluación de una lesión que no había sido apreciada en la evaluación en el consultorio. Los criterios para indicar una microlaringoscopia directa diagnóstica son altas puntuaciones del índice GRABS; los defectos de cierre glótico sin lesión tipo masa y la asimetría de fase y amplitud entre las ondas mucosas de ambas cuerdas; la desproporción entre los hallazgos de la estroboscopia o la endoscopia con la intensidad percibida de la disfonía; la disfonía severa objetivada mediante análisis acústico y aerodinámico, y las puntuaciones altas en el índice de incapacidad vocal. Recomendamos la realización de una microlaringoscopia diagnóstica en los casos de disfonía de origen incierto
