Background and Objectives Spectral gradient acoustic reflectometry (SGAR) determines the probability of middle ear fluid by measuring the response of the tympanic membrane to a sound. To assess the sensitivity and specificity of SGAR for the diagnosis of otitis media with effusion (OME) in the Korean population, we compared accurate diagnostic rates of OME obtained from SGAR and tympanometry. Pneumatic otoscope was used for diagnostic standard of OME. Subjects and Method SGAR and tympanometry were performed on 488 ears from May 27th, 2008 to July 30th, 2008. Exclusion criteria were the presence of tympanic membrane perforation, and/or pressure equalization tubes, noncompliance, otorrhea, external auditory canal stenosis and signs of acute inflammation such as fever or otalgia. In all cases, pneumatic otoscopic examination was conducted and diagnostic accurate rates of OME were calculated in SGAR and tympanogram. Results Using spectral gradients of 3 or higher as breakpoints for indicating OME, in the case of pediatrics under 2 years old, with the sensitivity of 58.3%, specificity of 94.7%, positive predictive value (PPV) of 77.8% and negative predictive value (NPV) of 87.8%. In the case of the pediatrics between 2 and 12 years old, it showed the sensitivity of 67.2%, specificity of 90.3%, PPV of 74.5% and NPV of 86.8%. In the case of the pediatrics over 12 years old, they showed sensitivity of 87.3%, specificity of 88.8%, PPV of 67.6% and NPV of 96.3%. Conclusion SGAR has the higher tendency of specificity and NPV, and will be a useful screeningtest with good portability and economical efficiency.
