Two-stage methods for reconstruction of congenital microtia have been widely utilised. To obtain a desirable auriculocephalic angle and provide a nutrient support to the constructed auricle, elevation of reconstructed ears using a costal cartilage graft, the anteriorly based mastoid fascial flap transfer and a skin graft was performed as the second operation for nine microtia patients. In this procedure, the mastoid fascial flap was used instead of the temporoparietal fascial flap. Following the elevation of the reconstructed ear the anteriorly based mastoid fascial flap was harvested. A carved costal cartilage was grafted at the posterior wall of the concha and covered with the mastoid fascial flap, followed by a full-thickness skin graft from the inguinal region. The skin grafts took well and the appropriate auriculocephalic angle was preserved in all cases. This method was easy to perform and did not leave any scar in the temporal hair-bearing area.
两阶段法重建先天性小耳畸形已被广泛应用。为获得理想的耳颅角并为构建的耳廓提供营养支持,对9例小耳畸形患者进行了第二次手术,即使用肋软骨移植、以乳突筋膜瓣为蒂向前转移以及植皮来抬高再造耳。在该手术过程中,使用乳突筋膜瓣替代了颞浅筋膜瓣。在抬高再造耳后,切取以乳突筋膜瓣为蒂向前转移的筋膜瓣。将雕刻好的肋软骨移植到耳甲后壁,并用乳突筋膜瓣覆盖,随后取自腹股沟区的全厚皮片移植。所有病例中植皮均成活良好,且保留了合适的耳颅角。该方法操作简便,在颞部有毛发区域未留下任何瘢痕。
