Pilonidal sinuses are acquired in the natal cleft as a result of dead hairs being pushed into skin abrasions by the movements of the buttock. Traditional surgical approaches have resulted in high recurrence rates. To avoid this, plastic procedures, such as the Z-plasty, have been advocated but have not been generally accepted. In a randomized trial, we compared Z-plasty with incision and drainage or marsupialization and found that no further surgical treatment was required in the Z-plasty group; in the control group, 40 per cent had repeated surgical treatment. We support Z-plasty for pilonidal sinuses.
藏毛窦是由于臀部运动将死毛发挤入皮肤擦伤处而在臀裂处形成的。传统手术方法导致复发率很高。为避免这种情况，有人提倡采用整形手术，如Z成形术，但尚未被普遍接受。在一项随机试验中，我们将Z成形术与切开引流或袋形缝合术进行了比较，发现Z成形术组无需进一步手术治疗；在对照组中，40%的患者接受了重复手术治疗。我们支持采用Z成形术治疗藏毛窦。
