To evaluate the epithelial "turn-in" flap for reconstruction of the internal lining in full-thickness nasal defects. Highlighted are its indications, technique, complications, and clinical success, particularly in comparison with the other common modalities for reconstructing this nasal lining. Also, to determine how the random flap withstands vigorous thinning.
A retrospective chart review and clinical follow-up of all patients with full-thickness nasal defects of the nose.
The patient pool comes from a tertiary care center that draws from a large geographic area in the Northwest. Both urban and rural demographics are represented.
Fifty-six patients with large full-thickness nasal defects were reviewed, 18 of which were reconstructed with the epithelial turn-in flap. The causes of the original defect were varied.
Full-thickness nasal defects were reconstructed in a layered fashion. The turn-in flaps were aggressively thinned to the subdermal plane to minimize flap bulk and airway compromise.
Attention was made to the size and precise location of the defect, the mode of reconstruction, flap viability, and nasal function.
Eighteen patients had turn-in flaps for reconstruction of the internal lining. Sixteen patients (89%) had 100% viability of their flaps. Seventeen (94%) reported normal nasal function.
The epithelial turn-in flap is a robust flap that provides dependable and functional results. One of the major advantages of this flap over other methods is that often there is no donor site morbidity. For many select defects, the turn-in flap remains a method of choice for repair of the internal lining.
评估上皮内翻瓣用于全层鼻缺损内衬重建的效果。重点关注其适应证、技术、并发症及临床成功率，特别是与其他常见的鼻内衬重建方式相比较。此外，确定随意皮瓣在进行强力薄化处理后的表现。
对所有患有全层鼻缺损的患者进行回顾性病历审查和临床随访。
患者群体来自西北一个广大地理区域的三级医疗中心，涵盖城市和农村人口。
对56例患有大面积全层鼻缺损的患者进行了审查，其中18例采用上皮内翻瓣进行重建。原发缺损的原因各不相同。
全层鼻缺损采用分层方式进行重建。将内翻瓣积极薄化至皮下平面，以尽量减少皮瓣体积和气道受压。
关注缺损的大小和精确位置、重建方式、皮瓣存活情况及鼻腔功能。
18例患者采用内翻瓣重建内衬。16例患者（89%）皮瓣100%存活。17例患者（94%）报告鼻腔功能正常。
上皮内翻瓣是一种可靠的皮瓣，能提供可靠且功能良好的效果。该皮瓣相对于其他方法的主要优势之一是通常不存在供区并发症。对于许多特定的缺损，内翻瓣仍是修复内衬的一种首选方法。
