We report the application of optical coherence tomography (OCT) to the diagnosis and evaluation of otitis media (OM). Whereas conventional diagnostic modalities for OM, including standard and pneumatic otoscopy, are limited to visualizing the surface of the tympanic membrane (TM), OCT effectively reveals the depth-resolved microstructure below the TM with very high spatial resolution, with the potential advantage of its use for diagnosing different types of OM. We examined the use of 840-nm spectral domain-OCT (SD-OCT) clinically, using normal ears and ears with the adhesive and effusion types of OM. Specific features were identified in two-dimensional OCT images of abnormal TMs, compared to images of healthy TMs. Analysis of the A-scan (axial depth scan) identified unique patterns of constituents within the effusions. The OCT images could not only be used to construct a database for the diagnosis and classification of OM but OCT might also represent an upgrade over current otoscopy techniques.

Otitis media [OM] is a serious healthcare concern worldwide. Acute otitis media is over-diagnosed. Symptoms are neither sensitive nor specific for the diagnosis of otitis media. Four characteristics of the tympanic membrane - position, mobility, color and degree of translucency should be evaluated and described in every examination. The most notable trends in the bacteriology of AOM during the past decade have been a rise in the proportion of patients infected with drug-resistant S. pneumoniae and an overall increase in beta-lactamase-producing H. influenza and M. catarrhalis. Antibiotic resistance to otogenic organisms occurs more frequently nowadays. Surgical management of otitis media is also discussed in this review

En niños, la otitis media aguda plantea varios problemas diagnósticos y terapéuticos. En este artículo se revisan los siguientes aspectos de esta entidad: epidemiología, factores de riesgo, fisiopatología, auxiliares del diagnóstico, etiología y tratamiento. Asimismo, se comentan puntos relevantes de su historia natural y de la clasificación más común de este tipo de inflamación

La Otitis Media, es uno de los motivos de consulta más frecuentes en pediatría. Por eso es necesario que manejemos muy bien los aspectos más importantes de esta enfermedad. Realizamos una revisión bibliográfica de este tema, haciendo énfasis en la etiopatogenia, métodos diagnósticos y tratamiento, esperando que esta sirva para el manejo óptimo de dicha patología
