Scalp and forehead defects represent one of the most complex defects for reconstruction. The nature of these sites being hair bearing, together with the complicated nature of the injuries, for example, electrical burns and motor vehicle accidents, and of course the aesthetic concern being in the face, all add to the complexity of reconstruction.
This is a case series representing the experience of the authors in using the "crane principle" in the reconstruction of various defects in the forehead and the scalp presented to emergency department, Cairo University Hospital, for the period between January 2018 and January 2019.
Twenty patients, 15 men and 5 women, presented with various soft tissue defects of the forehead and the scalp. The injuries of eighteen patients were due to motor vehicle accidents, and 2 patients had postelectrical burns. Age range was from 20 to 65 years, with a mean follow-up of 8 months. The number of total complications was 5. Three patients had wound dehiscence, and 2 patients had ulceration in the grafts placed at the flap donor site.
Crane principle represents an adequate reconstruction tool for forehead and scalp defects especially when the access to free flap and more complex reconstruction techniques is not available.
头皮和前额缺损是最复杂的重建缺损之一。这些部位有毛发，加上损伤的复杂性，如电烧伤和机动车事故，当然还有面部美学方面的考虑，所有这些都增加了重建的复杂性。
这是一个病例系列，展示了作者在2018年1月至2019年1月期间，在开罗大学医院急诊科，运用“起重机原理”重建前额和头皮各种缺损的经验。
20例患者，15例男性和5例女性，出现前额和头皮的各种软组织缺损。18例患者的损伤是由机动车事故所致，2例患者有电击伤后烧伤。年龄范围为20至65岁，平均随访8个月。总并发症数为5例。3例患者伤口裂开，2例患者在皮瓣供区植入的移植物处出现溃疡。
起重机原理是前额和头皮缺损的一种合适的重建工具，特别是在无法进行游离皮瓣和更复杂重建技术的情况下。
