在某些颅面综合征中，外观正常的外耳错位并不少见。本文报告10年来14例外耳复位术的经验。在这项技术中，使用后部切口来移动围绕外耳道的周围软组织，然后将其作为前旋转和提升的轴。可以实现高达8 mm的仰角和高达30度的旋转。外耳道的收缩和阻力限制了进一步的提升。Z成形术转移的鼻后正中皮瓣可以获得更大的旋转。
The malposition of an otherwise normal-appearing external ear is not uncommon in certain craniofacial syndromes. This paper presents a 10-year experience of 14 patients who underwent external ear repositioning. In this technique, a posterior incision is used to mobilize surrounding soft tissues circumferentially around the external auditory canal, which then serves as an axis for anterior rotation and elevation. Elevation of up to 8 mm and rotation up to 30 degrees can be achieved. Further elevation is limited by the ensuing constriction and resistance of the external auditory canal. More rotation can be achieved with a Z-plasty transposition of an inferiorly based postauricular skin flap.
