Radical maxillectomy is indicated for stage III and IV antroethmoidal carcinoma. In those cases where the anterior bony wall of maxillary antrum or the anterior facial soft tissue is involved or a previous Caldwell-Luc antrostomy was performed, a generous amount of cheek soft tissue has to be resected with the surgical specimen in order to achieve tumour-free margins. In such cases survival of the cheek flap is in jeopardy. Following orbital exenteration the resultant defect requires covering to promote healing and to protect the underlying bone. Traditionally, a skin graft has been used to line the orbital defect and the cheek flap. The pedicled temporoparietal galeal myofascial flap offers well-vascularized, reliable, supple and plentiful tissue which can be used to line both the orbit and the cheek, thus covering both sites with one flap. Such a case is presented and the surgical anatomy and technique are described.
根治性上颌骨切除术适用于III期和IV期鼻窦筛窦癌。在上颌窦前骨壁或前面部软组织受累的病例中，或既往曾行柯-陆氏上颌窦造瘘术的病例中，为获得无瘤切缘，必须将大量颊部软组织与手术标本一并切除。在这些情况下，颊部皮瓣的存活受到威胁。眶内容剜除术后，所形成的缺损需要进行覆盖以促进愈合并保护下方的骨骼。传统上，一直使用皮肤移植来衬里眼眶缺损和颊部皮瓣。带蒂颞顶帽状腱膜肌筋膜瓣提供了血运丰富、可靠、柔软且充足的组织，可用于衬里眼眶和颊部，从而用一块皮瓣覆盖两个部位。现展示这样一个病例并描述其手术解剖结构和技术。
