Methods 30 cases of nasal soft tissue de fects were reconstructed by different kinds of local flaps according to modified Burget′s nasal subunit. The Rintala flaps were used above the lowest level of low eyelids; at the area between low eyelids and the alar groove, the dorsal def ects were covered by ax-like local flaps and defects on side wall were reconstru cted by flaps rotated from the contralateral wall covered by skin graft; when it was below the highest level of alar groove, nasolabial flaps with subdermal ped ical were applied to nasal tip defection, and nasolabial local flaps to alar def ects, axial nasodorsum flaps supplied by the lateral nasal artery to defects inv olving columellae.

结合Burget鼻部美学分区，将其再分为三个区域，根据分区选用局部或邻位皮瓣修复鼻部各区软组织缺损30例(鼻根部以Rintala鼻额部局部皮瓣推进3例；鼻中段的鼻背部行双侧斧状局部皮瓣旋转3例；鼻侧壁行对侧壁局部皮瓣转移，供区植皮4例；鼻端部以鼻唇沟皮下蒂岛状瓣转移修复鼻尖部7例；鼻唇沟局部皮瓣旋转修复鼻翼部7例；鼻背轴型皮瓣旋转修复鼻小柱6例)。
