Resumen

La tiroplastia tipo I ha supuesto una importante mejora en el tratamiento de los pacientes con una incompetencia glótica. La valoración preoperatoria de estos pacientes mediante criterios objetivos es primordial. Los test de compresión manual de la laringe consisten en la manipulación de los cartílagos tiroides y cricoides, produciendo cambios en la posición de las cuerdas vocales. El test más valorado en la incompetencia laríngea es el test de compresión alar. Si se percibe una mejoría de la voz en el preoperatorio al realizar este test sugiere que la cirugía tendrá éxito. En este trabajo se presenta la evaluación objetiva del test de compresión alar sobre la glotis incompetente usando la espectrografía de banda estrecha.

Abstract

Thyroplasty type I has provided significant improvement to the treatment of patients with glottal incompetence. It is essential that patients be preoperatively evaluated using objective criteria. Laryngeal manual compression test are manipulations of the thyroid and cricoid cartilages that result in modifications of the position of the vocal folds. The most valuable laryngeal manual compression test for patients with glottal insufficiency is the lateral compression test. When this test results in a preoperative improvement in voice suggest that surgery will be successful. In this paper we present the objective evaluation of the effects of lateral compression test upon glottic incompetence by means of narrow band power spectrum analysis.
