We describe a new technique of helix advancement meatoplasty. This technique is useful in both mastoid surgery and some cases of otitis externa. The technique is designed to avoid the problems of (1) inferior positioning of the meatoplasty at the time of surgery, and (2) later inferior migration of the pinna (as can occur when the suspensory ligaments of the pinna have been cut or weakened). Such outcomes can result in a mastoid cavity which is difficult to clean as the approach to it is awkward; in such cases, it is common to have to look up into the cavity rather than directly into it. Helix advancement meatoplasty improves post-operative visualisation and aeration. It eases cleaning of the cavity by creating a more superiorly placed meatoplasty, which is supported by the tragus and is therefore less likely to drop.
我们描述了一种新的耳轮推进外耳道成形术技术。该技术在乳突手术和某些外耳道炎病例中均有用处。该技术旨在避免以下问题：（1）手术时外耳道成形术位置过低，以及（2）耳廓后期向下移位（如耳廓悬韧带被切断或减弱时可能发生的情况）。这些结果可能导致乳突腔难以清洁，因为进入乳突腔的途径很别扭；在这种情况下，通常不得不向上看入乳突腔而不是直接直视。耳轮推进外耳道成形术可改善术后的视野和通气。它通过创建一个位置更高的外耳道成形术来便于乳突腔的清洁，该外耳道成形术由耳屏支撑，因此不太可能下垂。
