Estudio del reflujo laringofaríngeo mediante pH-metría en el postoperatorio inmediato de los laringectomizados / Study of laryngopharyngeal reflux using pH-metering in immediate post-op of laryngectomized patients

Objetivo: Se desconoce la incidencia de reflujo laringofaríngeo (RLF) y de reflujo gastroesofágico (RGE) en el postoperatorio reciente de las laringectomías. Nos propusimos evaluar la incidencia y las características del RLF y el RGE en pacientes laringectomizados, mediante pH-metría de dos canales durante las 48 horas posteriores a la cirugía. Material y método: Estudio prospectivo de 50 pacientes mediante la colocación intraoperatoria de una sonda de pH de dos canales, el análisis descriptivo de cuatro variables de pH a nivel del sensor proximal y definición del RGE y el RLF. Resultados: La incidencia de RLF en el postoperatorio de los laringectomizados oscila entre el 30 y el 40 % y la de RGE, en el 40 %. Conclusiones: El RLF y el RGE se detectan en un porcentaje elevado de pacientes en el postoperatorio inmediato de las laringectomías

Objective: Little is known about incidence of laryngo-pharyngeal reflux (LPR) and gastroesophageal reflux (GER) in the early postoperatory period of laryngectomy. To evaluate the effect and characteristics of the LPR and GER in laryngectomized patients, by means of double pH-metry during 48 hours after surgery. Material and method: In 50 patients, 48-hour double-probe pH monitoring was performed in postoperative of laringectomy, after a intraoperatory placement. Descriptive analysis of 4 variables of pH to level of the sensor proximal, and definition of the presence of esofagic reflux and LPR. Results: The incidence of LPR in the postoperatory of laringectomy ranges between 30 % and 40 %. A esofagic reflux has been observed in 40 %. Conclusions: A high incidence of LPR and GER in the postoperatory immediate of laryngectomized patients was found

Otorhinolaryngologic manifestations in Chiari malformation.

The Chiari malformation causes herniation of the cerebellar amygdalae through the foramen magnum, resulting in the descent of the brain stem and/or traction on the lower cranial pairs. It is important for otolaryngologists to recognize Chiari malformations as part of the differential diagnosis of balance disorders, because patients may initially exhibit symptoms related to the vestibular system, including ataxia, nystagmus, or vertigo. We report 2 cases.
