Revisión de los modelos de producción de voz después de una laringectomía total: opciones de calidad de voz

Abstract

El paciente laringectomizado es aquel que debido a un proceso cancerígeno ha sido sometido a una intervención quirúrgica cuyo resultado es la extirpación total de la laringe. Como consecuencia de esta operación el paciente sufre una serie de modificaciones anatómicas que conllevan la alteración y/o pérdida de determinadas funciones, siendo la pérdida de la voz, y por tanto de la comunicación oral, la limitación principal a la que se enfrentan estos pacientes. Es por ello, que el proceso de tratamiento y rehabilitación post-quirúrgico tiene como uno de sus objetivos principales el restablecimiento de la comunicación oral. Para ello se deberá dotar al paciente de una nueva fuente de sonido (neo-glotis), la cual tendrá que suplir o emular la función vibratoria anteriormente realizada por glotis laríngea. El objetivo de este trabajo es analizar desde una perspectiva biomecánica y acústica los distintos tipos de voces que pueden representar una opción para el paciente laringectomizado. Se pretende mostrar las ventajas y limitaciones de cada modelo de producción de una forma clara y objetiva; comprensible tanto para el clínico como para el paciente, con el fin de orientar en la toma de decisiones. Finalmente se realiza un análisis acústico de la voz de cuatro pacientes femeninas laringectomizadas. Cada muestra de voz se corresponde con un modelo de producción diferente: laringe artificial, prótesis fonatoria y erigmofonía. Los resultados del estudio permiten valorar de una forma objetiva las características acústicas de los distintos tipos de voces esofágicas.

The laryngectomized patient is one who because of a carcinogenic process has undergone surgery which results in complete removal of the larynx. Following this operation the patient undergoes a series of anatomical changes that involve the alteration and/or loss of certain functions, being the voice loss, and the oral communication, the main problem faced by the patients. Therefore, the restoration of the oral communication is one of the main objectives in the treatment process and post-surgical rehabilitation. This should give the patient a new sound source, which will have to replace or emulate the function of the laryngeal glottis. The objective of this work is to analyze from a biomechanical and acoustic perspective the different types of voices that can postulated as an option for laryngectomized patients. We show the advantages and limitations of each model of production, in a clear, objective and understandable way for both clinicians and patients, to guide the decision-making. Finally, an analysis of the voice sound of four female laryngectomized patients is carried out. Each voice sample corresponds to a different voice production model: artificial larynx, phonatory prosthesis and erygmophony. The results provide an objective assessment of the acoustic characteristics of each voice.
