BACKGROUND
Otoacoustic Emission (OAE) is frequently recorded in various body positions for infants. However, little is available about whether these deviations will produce non-pathological effects on the clinical results. The current study assessed body position's effect on infants' inner ear function.
METHODS
Sixty normally hearing infants participated in an analytical cross-sectional study. Distortion-product OAEs (DPOAEs) were measured in the supine, side-lying, and upright positions. The DPOAE amplitude and signal-to-noise ratio (SNR) were recorded across the 1500 to 6000 Hz range.
RESULTS
The mean DPOAE amplitude and SNR values were significantly greater in the upright position than supine and side-lying positions (p < 0.05). These differences were more pronounced in the 3000 to 6000 Hz range. The effects of gender and ear asymmetry on DPOAEs were not statistically significant.
CONCLUSION
Our findings suggested that the upright position could be regarded as the best position for assessing DPOAEs in infants.
背景
耳声发射（OAE）常用于在各种体位下记录婴儿的情况。然而，关于这些偏差是否会对临床结果产生非病理性影响的信息却很少。本研究评估了体位对婴儿内耳功能的影响。
方法
60名听力正常的婴儿参与了一项分析性横断面研究。在仰卧位、侧卧位和直立位测量畸变产物耳声发射（DPOAE）。在1500至6000赫兹范围内记录DPOAE的幅值和信噪比（SNR）。
结果
直立位时DPOAE的平均幅值和SNR值显著高于仰卧位和侧卧位（p<0.05）。这些差异在3000至6000赫兹范围内更为明显。性别和耳不对称对DPOAE的影响无统计学意义。
结论
我们的研究结果表明，直立位可被视为评估婴儿DPOAE的最佳体位。
