Abstract

Objective To explore the value of CTA combined augmented reality(AR) navigation in tongue reconstruction with free anterolateral thigh perforator (ALTP) flaps. Methods From December, 2016 to December, 2018, 9 cases of tongue cancer patients were treated with lingual reconstruction with the free ALTP flap. The dominant perforator was selected according to CTA before operation. The origin, course, locations at the level passing through the fascia lata of the perforators and digital flaps were located and marked under the guidance of AR navigation technology. The flaps area were 6 cm×8 cm-8 cm×12 cm, and the donor sites were closed directly. The effect of the AR navigation was explored intraoperatively. The function of reconstructed tongue and donor site were followed-up 3 to 6 months post-operatively. Results All navigation-positioned perforators were confirmed by AR preoperatively. Intraoperative exploration showed that the perforators were accurately located. All flaps survived, and no vascular crisis occurred. The donor sites healed primarily with linear scars. The tongue was plump, and the function of voice and swallowing were favorable. Conclusion CTA combined AR navigation has the advantages of accurate location, easy to use and low cost in tongue reconstruction with free ALTP flaps. It is a worthy method to be popularized. Key words: Anterolateral thigh perforator flap; Tongue reconstruction; Augmented reality technology; CT angiography; Microsurgical technique

CTA联合增强现实导航在股前外侧穿支游离皮瓣舌重建中的应用（附9例报告）

目的探讨CTA联合增强现实导航在股前外侧穿支（ALTP）游离皮瓣舌重建中的应用价值。方法自2016年12月至2018年12月，对9例舌癌症患者进行游离ALTP皮瓣舌再造术。术前根据CTA选择主要穿支。在AR导航技术的指导下，定位并标记了穿支和数字皮瓣穿过阔筋膜的起点、路线、位置。皮瓣面积为6cm×8cm～8cm×12cm，供区直接闭合。术中探讨了AR导航的效果。术后随访3～6个月重建舌及供区功能。结果所有导航定位穿支术前均经AR证实。术中探查显示穿支位置准确。所有皮瓣均存活，未发生血管危象。供区愈合主要为线状瘢痕。舌头丰满，声音和吞咽功能良好。结论CTA联合AR导航在游离ALTP舌片重建中具有定位准确、使用方便、成本低的优点。这是一种值得推广的方法。关键词：股前外侧穿支皮瓣；舌再造；增强现实技术；CT血管造影术；显微外科技术
