The defect after surgical resection of sinonasal malignant tumors is normally reconstructed using free flaps obtained from donor sites. There is no report of using the palatal island flap to reconstruct defects after surgery. We aimed to describe our technique of soft tissue reconstruction through anterior pedicled inferior turbinate (APIT) flap in conjunction with palatal flap for standard inferior maxillectomy with hard palate resection and its outcomes and to discuss its advantages and disadvantages compared with free-flap reconstruction.
For resection of malignant tumors arising from the anterior nasal septum, we preserved the hard palate during maxillectomy using a palatal island flap and an anterior pedicled inferior turbinate flap.
One patient developed a small oroantral fistula, which was sealed with a denture. The other patient had a good outcome.
Our technique of maxillectomy is useful for selected cases of sinonasal malignancy that require maxillary floor resection.
鼻窦恶性肿瘤手术切除后的缺损通常采用取自供区的游离皮瓣进行修复。目前尚无使用腭岛状皮瓣修复术后缺损的报道。我们旨在描述通过前蒂下鼻甲（APIT）皮瓣联合腭瓣进行标准下颌骨次全切除术并切除硬腭的软组织重建技术及其效果，并讨论其与游离皮瓣重建相比的优缺点。
对于起源于前鼻中隔的恶性肿瘤切除，我们在颌骨切除术中使用腭岛状皮瓣和前蒂下鼻甲皮瓣保留硬腭。
1例患者出现小的口鼻瘘，用义齿封闭。另一例患者预后良好。
我们的颌骨切除技术对某些需要切除上颌底的鼻窦恶性肿瘤病例有用。
