La hipoacusia tiene repercusion negativa en el aprendizaje y comportamiento social de los ninos, por lo que se hace necesaria la aplicacion de tecnicas quirurgicas cada dia mas eficientes que reduzcan esta problematica. Con el objetivo de demostrar la eficacia de una nueva modalidad quirurgica consistente en realizar adenoidectomia y doble miringotomia con aspiracion del contenido seromucoso y de proponer una estrategia para solucion quirurgica definitiva en el nivel secundario y preventiva en el nivel primario, se realizo una investigacion de innovacion-tecnologica, descriptiva, longitudinal prospectiva en ninos con hipoacusia conductiva por otitis media serosa secundaria a hipertrofia adenoidea, que asistieron a las consultas de audiologia del Hospital Pediatrico Provincial Docente Portilla y del Policlinico Universitario Dr. Ernesto de Sandino. El universo estuvo constituido por todos los ninos con hipoacusia conductiva registrados en consulta de audiologia. La muestra resulto de 109 pacientes con hipoacusia por Otitis Media Serosa secundaria a Hipertrofia Adenoidea, provenientes de 10 municipios de nuestra provincia, entre los 4 y 12 anos de edad; mediante muestreo intencional. A todos los pacientes se les realizo examen otorrinolaringologico y audiometria tonal. Se utilizaron metodos de encuesta, analisis documental y de la Estadistica Descriptiva utilizando medidas de frecuencias absolutas y relativas porcentuales. Se calcularon intervalos de confianza para algunas de las frecuencias relativas buscadas y previo consentimiento informado se trataron quirurgicamente, reevaluados en consulta, donde se comprobo que 108 pacientes evolucionaron satisfactoriamente, concluyendo que es una tecnica eficaz.

ABSTRACT Hypoakusia has a negative repercussion in learning and social behaviour in children so it is mandatory the implementation of surgical techniques in order to minimize this condition.. A new descriptive longitudinal and prospective technique was performed in children suffering from conductive hypoakusia due to serous otitis media secondary to adenoid hypertrophia attending to the hearing care office at Pepe PortillaPediatric Hospital and Dr.Ernesto Guevara Policlinic in Sandino in order to show the efficacy of a new definitive surgical technique (adenotomy and double miringotomy with aspiration of the seromucus content ) and to propose an strategy for a definitive surgical solution in the secondary level being preventive at primary level. Universe was comprised of all the children suffering from conductive hypoakusia who were recorded in the auditory care office, the sample had 109 patients coming from 10 municipalities of our province and suffering from hipoakusia due to serous otitis media secondary to adenoid hypertrophia, they were 4 and 12 year old. All the patients were given otolaringologic examinations and tonal audiometry. Survey methods, documental analisis and descriptive statistic method were applied using relative and absolute percentage frequency measurements.Confidence intervals for some relative frequencies and previous informed consent were estimated; patients were surgically treated and reevaluated at the office showing that 108 patients had a satisfactory natural history and concluding that it is an efficient technique.
