Resumen
Objetivo

Estudiar la eficacia terapéutica, la voz y las complicaciones aparecidas tras la laringuectomía casi total de Pearson en el carcinoma laríngeo avanzado (T3 y T4).

Material y método

Estudio retrospectivo de 23 casos intervenidos en los últimos 9 años en nuestro hospital.

Resultados

La tasa de supervivencia fue del 91,3% y del 86,9% a los 3 y 5 años respectivamente. No presentamos ningún caso de recidiva local. El tiempo medio de adquisición de la voz fue de 51 días. Se observó una diferencia estadísticamente significativa en el análisis de voz (palabras/minuto, Jitter, PPQ, SPPQ, RAP, APQ, SAPQ, Shimmer, HNR, NNE) tomando como referencia sujetos sanos (Medivoz). El faringostoma fue la complicación más frecuente (60,86%).

Conclusiones

El control local del cáncer ha sido similar al observado con la laringuectomía total (LT). La laringuectomía casi total es una alternativa válida para el cáncer de laringe avanzado, presentando una aceptable morbilidad y conservación de la voz.

Abstract
Objective

To investigate the oncological efficiency, voice and complications of Pearson´s near-total laryngectomy for advanced laryngeal cancers (T3, T4).

Materials and Methods

A retrospective review of 23 cases of near-total laryngectomy (carried out in our Hospital in the last nine years) was undertaken.

Results

None of the cases developed laryngeal mucosal recurrences. The overall three and five years disease free survival were 91,3% and 86,9%. Mean phonation time was 51 days. A statistically significant results were observed in our voice analysis (words/minute, Jitter, PPQ, SPPQ, RAP, APQ, SAPQ, Shimmer, HNR, NNE) taking as a reference healthy people (Medivoz). The pharyngeal fistula was the most frequent complication (60,86%).

Conclusions

The local control of cancer was similar to that expected with total laryngectomy. Near-total laryngectomy is a valid alternative for extended laryngeal and neighbouring cancers with an acceptable morbidity and success rate for voice preservation.
