Choanal atresia is a significant congenital anomaly, which may be associated with other congenital anomalies. Recommendations have been previously proposed for neonatal screening of all newborns to detect this condition. A previously unreported, simple method using the automatic tympanometer to screen newborns for congenital choanal atresia is proposed. A prospective study was performed over a one-month period on all newborns at El-Sahel Teaching Hospital, Cairo, to evaluate the efficacy of this manoeuvre. The nostrils of 143 newborn infants were evaluated during the study period. The sensitivity of the technique in diagnosing a patent nostril was 100 per cent. The specificity of the technique for detecting distal obstruction was 100 per cent. There were no complications of the described procedures. The study revealed that the novel method of screening for choanal atresia in newborns using the automatic tympanometer is simple, minimally invasive and highly reproducible.
后鼻孔闭锁是一种严重的先天性异常，可能与其他先天性异常相关。此前已提出对所有新生儿进行新生儿筛查以检测这种情况的建议。本文提出了一种以前未报道过的、使用自动鼓室计筛查新生儿先天性后鼻孔闭锁的简单方法。在开罗的萨赫勒教学医院对所有新生儿进行了为期一个月的前瞻性研究，以评估该操作的有效性。在研究期间对143名新生儿的鼻孔进行了评估。该技术诊断鼻孔通畅的敏感性为100%。检测远端阻塞的技术特异性为100%。所述操作无并发症。研究表明，使用自动鼓室计筛查新生儿后鼻孔闭锁的新方法简单、微创且高度可重复。
