本研究旨在报道带髂嵴旋髂深动脉穿支皮瓣（DCIAPF）修复下颌骨缺损的临床经验，并分析相关解剖数据，指导临床应用。该研究纳入了 40 名下颌缺损患者，他们在肿瘤切除术后接受了 DCIAPF 重建。术中测量与DCIAPF结构相关的解剖特征，包括穿支的位置、皮板的活动度、血管蒂的长度和皮板的脂肪组织厚度。确定了三种类型的 DCIAPF 穿支： I 型，具有优势穿支，在 17 名患者 (42.5%) 中观察到； II 型，20 名患者（50%）的优势穿支分为多个小分支； III 型，三名患者 (7.5%) 没有明显的优势穿支。总之，DCIAPF 提供了足够的骨组织和令人满意的软组织。版权所有 © 2024 国际口腔颌面外科医师协会。由爱思唯尔公司出版。保留所有权利。

The aim of this study was to report the clinical experience of repairing mandibular defects with a deep circumflex iliac artery perforator flap with iliac crest (DCIAPF) and to analyse the relevant anatomical data to guide clinical application. Forty patients with mandibular defects, who underwent reconstruction with a DCIAPF after oncological resection were included in the study. During the operation, anatomical features relevant to the structure of the DCIAPF were measured, including the position of the perforator, mobility of the skin paddle, length of the vascular pedicle, and adipose tissue thickness of the skin paddle. Three types of DCIAPF perforator were identified: type I, with a dominant perforator, which was observed in 17 patients (42.5%); type II, with a dominant perforator that divides into multiple tiny branches, in 20 patients (50%); type III, with no visible dominant perforator, in three patients (7.5%). In summary, the DCIAPF provides adequate bone tissue and satisfactory soft tissue.Copyright © 2024 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.
