During the last decade numerous advances have been made in otolaryngology. The decade has also seen a number of modifications in diagnosis and therapeutic techniques. The most important advances were in the fields of otology and audiology. Therapeutically the treatment of deafness has seen the greatest advances. Conductive hearing loss occurs when sound cannot reach the cochlea. The blockage may be due to abnormality in the canal, the eardrum or the osicles, including the footplate of the stapes. Lesions central to the footplate produce perceptive hearing loss.
在过去十年中，耳鼻喉科学取得了许多进展。这十年间，诊断和治疗技术也有了一些改进。最重要的进展出现在耳科学和听力学领域。在治疗方面，耳聋的治疗取得了最大进展。当声音无法到达耳蜗时，就会发生传导性听力损失。堵塞可能是由于外耳道、鼓膜或听小骨（包括镫骨底板）异常所致。镫骨底板中枢的病变会导致感音性听力损失。
