ABSTRACT
The exact mechanism of the pneumatization of the mastoid air cell system and the factors influencing the pneumatization are poorly understood. Both genetic as well as acquired factors have been implicated to influence this pneumatization process. Since pneumatization of the mastoid air cell system is considered an important prognostic factor in the outcome of reconstructive ear surgeries, a cohort study was carried out to assess the role of two important acquired factors i.e. duration of chronic otitis media and auditory tube functional status on the pneumatization of mastoid air cells. 50 individuals with unilateral chronic otitis media underwent assessment of their mastoid air cell system using planimetry and auditory tube functions using flourescein dye nasopharyngoscopy. The results were in accordance with the previous studies indicating a definite influence of chronic middle ear disease on the pneumatization process, although the duration of disease was not significant. In contrast to some of the previous studies, no influence of auditory tube functional status was found on the mastoid pneumatization.
RESUMEN
El mecanismo exacto de la neumatización del sistema de células mastoideas y los factores que influencian este proceso es pobremente comprendido. Factores genéticos, como también adquiridos, han sido implicados en el proceso de neumatización del sistema de células mastoideas. Esta neumatización es considerada un factor de importante pronóstico en la conducción de las cirugías reconstructivas de oído. Hemos llevado a cabo un estudio para explicar el rol de dos importantes factores adquiridos en la duración de las otitis media crónica y el status funcional de la tuba auditiva en la neumatización de las células mastoideas. En 50 individuos, con otitis media crónica unilateral, se estudió su sistema de células aeríferas mastoideas usando la planimetría y las funciones de la tuba auditiva usando fluorescina, vía nasofaringoscopía. Los resultados concuerdan con estudios previos, indicando una influencia definida de enfermedades crónicas del oído medio en el proceso de neumatización, aunque la duración de la enfermedad no fue significativa. En contraste con los estudios previos, no se encontró influencia del status funcional de la tuba auditiva en la neumatización mastoidea.
