Cryptotia is a congenital anomaly in which the superior aspect of the helical cartilage is buried beneath the scalp, resulting in an absence of the auriculocephalic sulcus. Treatments have included splinting, skin grafts, and a variety of local flaps. We present a modification of the trefoil flap, initially described by Wesser in 1972. The modifications include wider undermining of the opposing trefoil flap (≤ 2-4 cm), staggering the closure of the helical apices, and expanding the base of the auricular trefoil flap such that it extends over a larger circumference of the helical rim. The senior author (K.S.) has achieved excellent results with this method and has alleviated the need for skin grafts or local preauricular flaps to close the donor site.
隐耳是一种先天性畸形，其中耳轮软骨的上半部分埋于头皮之下，导致耳颅沟缺失。治疗方法包括夹板固定、皮肤移植和多种局部皮瓣。我们介绍一种三叶皮瓣的改良术式，该术式最初由韦塞尔于1972年描述。改良之处包括在相对的三叶皮瓣下更广泛地剥离（≤2 - 4厘米）、交错缝合耳轮顶端以及扩大耳三叶皮瓣的基部，使其延伸至耳轮边缘更大的圆周范围。资深作者（K.S.）采用这种方法取得了极佳的效果，并且无需进行皮肤移植或耳前局部皮瓣来闭合供区。
