Complete otological examinations, including audiograms, were carried out on 504 British Columbia Indians of the Mount Currie Reservation. Of these, 79 were found to have evidence of current middle ear pathology, while 226 were known to have had previous disease. Among 364 subjects who could be formally tested, 112 had a 15-decibel or greater hearing loss in the speech frequencies. Among these Indians, middle-ear disease began early in life and recurrences were frequent. The prevalence of aural disease was related to poor social conditions, family history and presence of nasal discharge. No other relationships could be demonstrated, and there was no evident benefit from adenotonsillectomy. No secretory otitis or otosclerosis and almost no sensorineural high-tone hearing loss were discovered.
对库里山保留地的504名不列颠哥伦比亚印第安人进行了全面的耳科检查，包括听力图检查。其中，79人有中耳病变的迹象，226人曾患过中耳疾病。在364名能够进行正式测试的受试者中，112人在言语频率上有15分贝或更高的听力损失。在这些印第安人中，中耳疾病在早年就开始出现，且复发频繁。耳部疾病的患病率与社会条件差、家族病史和流鼻涕有关。未发现其他关联，腺样体扁桃体切除术也没有明显益处。未发现分泌性中耳炎或耳硬化症，几乎没有感音神经性高音听力损失。
