摘要：

ObjectiveTo compare hearing thresholds at 250 and 500 Hz in pediatric patients with tympanic membrane perforations (TMP) using RadioEar IP30 insert earphones and RadioEar TDH50s 3045 supra-aural headphones Study DesignProspective clinical pilot study. SettingPrimary Children's Hospital, Utah. MethodsChildren (<18 years of age) were prospectively enrolled into 2 groups based on the presence of TMPs (no TMP, TMP). Hearing thresholds were measured at 250 and 500 Hz using RadioEar IP30 insert earphones and RadioEar TDH50s 3045 supra-aural headphones for all participants. ResultsAt 250 and 500 Hz, hearing thresholds were significantly higher when recorded with insert earphones than with supra-aural headphones in pediatric participants with TMPs. At 250 Hz, thresholds obtained with inserts were 14.7 +/- 7.2 dB (P < .001) higher than thresholds obtained with supra-aural headphones and 8.0 +/- 7.5 dB higher (P < .01) at 500 Hz. ConclusionLow-frequency hearing thresholds were significantly higher when measured with insert earphones in patients with TMPsbut not in patients without TMPs. A diagnosis of low-frequency hearing loss must be interpreted with caution when using insert earphones in participants with TMPs.
