所有腭瓣均以腭大动脉为基础,并认为其完整性是腭瓣成功的关键。然而,蒂在后部的腭瓣,仅能利用腭前1/3柔顺性不佳的腭部粘骨膜行再造手术,无论质地还是大小均不够理想,修复上颌结节部巨大缺损时尤其如此。本文作者介绍了一种蒂在前部侧位推进腭瓣,特别适用于传统腭瓣修补困难的上颌结节部巨大缺损。经12例临床应用效果良好。 首先切开口腔上颌窦边缘上皮,潜行分离颊侧粘骨膜以准备好创缘,然后标出皮瓣轮廓。该皮瓣设计为测位推进皮瓣,以缺损的近中缘为皮瓣的外侧缘,后缘止于硬腭后缘稍后,应包含有腭大动脉。中线侧延伸于切牙孔下,外侧如一般腭瓣。可切除缺损前部的部分粘骨膜,以利皮瓣就位,并避免在旋转轴线上形成局部隆 All palatalloids are based on the palatal aorta, and its integrity is considered as the key to the success of the palatal flap. However, pedicle pedicle flap at the posterior part of the palate can only utilize the palatal mucoperiosteum, which has poor compliance in the first one third of the palate, and is not ideal for both the texture and the size. This is especially true when repairing the huge defect in the maxillary nodules. The authors describe a pedicle propulsion palatal flap in the anterior flank that is particularly suitable for the vast defect of maxillary nodules that are difficult to repair with traditional palatal flap repair. After 12 cases of clinical application of good effect. First open the oral maxillary sinus marginal epithelium, sneak separation buccal mucoperiosteal to prepare a margin, and then marked the outline of the flap. The flap is designed to position the prolapse flap, with the proximal and middle margin of the defect as the lateral margin of the flap, and the posterior margin ending later than the posterior margin of the palate, which should include the palatal artery. The midline extends under the incisor hole, the outer side of the general palatal flap. Part of the mucoperiosteum in the anterior part of the defect can be resected to allow the flap to sit in place and to avoid the formation of localized lumps on the axis of rotation
