Tissue expansion allows optimal aesthetic reconstruction by the use of a similar adjacent tissue to reconstruct a defect without creation of significant donor site morbidity, especially in the face and upper neck area.
A total of 78 patients underwent facial reconstruction by insertion of a tissue expander (TE) in the cheek or the neck due to burn scar, traumatic scar, leschmaniasis or large pigmented nevi.
All reconstructions were completed satisfactorily; complications were: complete extrusion (2.6%), incomplete extrusion (3.8%), partial necrosis (14.1%), haematoma (6.4%), wide scar (33.3%), hypertrophic scar (17.9%), lower lid ectropion (1.3%), post-expansion atrophy (2.6%), permanent decrement in sensation (1.3%), sagging (14.1%) and infection (2.6%).
The lateral facial areas and neck contain essentially the same type of skin; hence, tissue expansion allows optimal aesthetic reconstruction by the use of a similar adjacent tissue and expanding either the lower face or the neck interchangeably without creation of major donor site morbidity; even when we use free flaps for coverage, although we achieved good contour and sufficient bulk, but due to poor colour match, reconstruction with expanded skin of the upper neck is needed for better result.
组织扩张术通过使用相似的邻近组织来重建缺陷，从而实现最佳的美学重建，同时避免产生重大供区并发症，特别是在面部和颈部上侧区域。
由于烧伤瘢痕、创伤性瘢痕、勒雪氏病或大色素痣，共有 78 例患者在颊部或颈部通过插入组织扩张器 (TE) 进行面部重建。
所有重建均令人满意完成；并发症包括：完全挤出（2.6%）、不完全挤出（3.8%）、部分坏死（14.1%）、血肿（6.4%）、宽瘢痕（33.3%）、增生性瘢痕（17.9%）、下睑外翻（1.3%）、扩张后萎缩（2.6%）、感觉永久性减退（1.3%）、下垂（14.1%）和感染（2.6%）。
侧面部和颈部区域包含基本相同类型的皮肤；因此，组织扩张术允许通过使用相似的邻近组织进行最佳的美学重建，并且可以互换地扩展下面部或颈部，而不会产生重大供区并发症；即使我们使用游离皮瓣进行覆盖，尽管我们实现了良好的轮廓和足够的体积，但由于颜色匹配不佳，仍需要使用上颈部扩张的皮肤进行更好的重建。
