ABSTRACT

OBJECTIVES: To assess the diagnostic capacity of intraoperative neurophysiological monitoring with respect to "gold standard" microscopic findings of facial canal dehiscence in middle ear cholesteatoma surgery. STUDY DESIGN, PATIENTS AND SETTING: We carried out a retrospective cohort study of 57 surgical interventions for cholesteatoma between 2008 and 2013 at Hospital Universitario de Canarias, Spain. DIAGNOSTIC INTERVENTIONS: Each patient underwent preoperative computed tomography (CT), intraoperative neurophysiological monitoring and intraoperative inspection of the facial nerve during microsurgery. Diagnostic concordance on the presence/absence of facial canal dehiscence was assessed in 54 surgical interventions. MAIN OUTCOME: Presence of facial canal dehiscence. RESULTS: Of 57 interventions, 39 were primary surgeries; 11 (28.2%) showed facial canal dehiscence. and 18 were revision surgeries; 6 (33.3%) showed facial canal dehiscence. The facial nerve was not damaged in any patient. Facial canal dehiscence was observed in 17 (29.82%) interventions. We used intraoperative microscopic findings as the gold standard. Neurophysiological study showed a sensitivity of 94.1, specificity 97.3, positive predictive value (PPV) 57.8 and negative predictive value of 97.2. CT showed a sensitivity of 64.7, specificity 78.4, PPV 57.8 and negative predictive value of 82. CONCLUSIONS: Our neurophysiological study showed greater sensitivity and higher PPV than CT for the detection of facial canal dehiscence. We found no relationship between disease progression time and the presence of facial canal dehiscence.

ABSTRACT

Las glándulas salivares menores se presentan en mayor proporción en el paladar. Es allí donde los tumores benignos o malignos de las mismas aparecen con mayor frecuencia. El carcinoma mucoepidermoide (CM) es el segundo en frecuencia, tras el cilindroma, que puede aparecer en este tipo de glándulas. Su diagnóstico precoz y tratamiento quirúrgico se hacen necesarios dada su tendencia a la invasión tisular local o la formación de metástasis a distancia (AU)

ABSTRACT

Una aplicación cada vez más importante de la audiometría de alta frecuencia es la monitorización de los tratamientos considerados potencialmente ototóxicos.Sin embargo, establecer unos umbrales auditivos de alta frecuencia sigue siendo una tarea difícil, principalmente debido a la diversidad de los sistemas empleados y de los métodos de calibración.El objetivo de este estudio ha sido establecer unos umbrales auditivos de alta frecuencia en función de la edad, que puedan servir como parámetros de referencia. Estudiamos a 162 pacientes control que fueron sometidos a una audiometría tonal liminar de alta frecuencia, calculando los umbrales para las frecuencias comprendidas entre los 10 y 20 KHz.Los resultados se presentan en relación a grupos de edad, y sugieren, como otros autores, que los umbrales auditivos aumentan con la edad y con la frecuencia. Destacamos la contaminación medioambiental y la presbiacusia dentro del grupo de los principales factores etiológicos que justificarían este agravamiento progresivo de la capacidad auditiva con el tiempo.
