© JLO (1984) Limited 2015.Objectives: This study aimed to investigate the diagnostic value of wideband acoustic absorbance testing in otitis media with effusion. Methods: This prospective study compared middle-ear wideband acoustic absorbance rates in three paediatric patient groups: a healthy group of 34 volunteers; 48 patients diagnosed with otitis media with effusion; and 28 patients with chronic effusion but no sign of effusion during myringotomy. The diagnostic value of absorbance testing was analysed with the receiver operating characteristic test. Results: The wideband acoustic absorbance rate was significantly lower in the otitis media with effusion group than in both the otitis media and healthy groups at the 0.375-2 kHz averaged mean absorbance (p < 0.017 and p < 0.001, respectively). Receiver operating characteristic analysis showed the highest diagnostic value for the 0.375-2 kHz averaged mean (area under the curve 0.984), followed by those at 1 and 1.5 kHz (area under the curve: 0.973 and 0.967, respectively). Conclusion: The wideband acoustic absorbance test is more accurate for detecting middle-ear effusion compared with conventional 226-Hz tympanometry. Its practicality and objectivity suggest that the wideband acoustic absorbance test may be a better alternative for diagnosing otitis media with effusion.
