The rhomboid and other 60 degrees transposition flaps have theoretical and practical disadvantages for many applications. A better flap for these is one having an angulation of 30 degrees at its distal end. When this 30 degrees flap is combined with the M-plasty, a versatile and cosmetically favorable repair is provided for many surface defects. In fact, over the years, it has become our most useful method of closure with flaps. Fundamentally, it allows sharing of tensions of closure better than does the rhomboid flap, produces less level disparities or protrusions than does any 60 degrees flap, and its resulting scar length is only fractionally longer than that of the rhomboid flap. Rhomboid and other 60 degrees angle flaps have been exceedingly valuable tools to many surgeons; the 30 degrees flap combined with M-plasty should be significantly more useful.
菱形皮瓣及其他60度转位皮瓣在许多应用中存在理论和实际的缺点。对于这些情况，更好的皮瓣是一种在其远端有30度角的皮瓣。当这种30度皮瓣与M形整形术结合时，可为许多体表缺损提供一种多功能且美观的修复方法。事实上，多年来，它已成为我们最常用的皮瓣闭合方法。从根本上说，它比菱形皮瓣能更好地分担闭合张力，比任何60度皮瓣产生的平面差异或突出更小，并且其产生的瘢痕长度仅比菱形皮瓣略长。菱形皮瓣和其他60度角皮瓣对许多外科医生来说一直是非常有价值的工具；结合M形整形术的30度皮瓣应该会更有用。
