Given the importance of vascularized flaps, this study presents a new technique for reconstructing skull defects using a pedicled palatal flap via the soft palate.
Five preserved cadaveric specimens were used to demonstrate the sequential steps involved in harvesting the palatal flap. In addition, 20 normal paranasal sinus computed tomography scans were analyzed to determine potential measurements of the flap (area, perimeter, greatest anteroposterior distance, and greatest transverse distance).
The average flap area in females and males was 11.8cm2 and 12.7cm2, respectively. The average perimeter in females and males was 13.5cm and 14.0cm, respectively. In all cases, the flap reached the infratemporal fossa and lower clivus.
The palatal flap via the soft palate described in this study proved to be a metrically viable alternative in cadaveric and tomographic studies for use in endonasal surgeries, as well as for skull base and adjacent regions.
鉴于带血管蒂皮瓣的重要性，本研究提出一种通过软腭使用带蒂腭瓣重建颅骨缺损的新技术。
使用5个防腐尸体标本演示获取腭瓣所涉及的连续步骤。此外，分析20例正常鼻窦计算机断层扫描，以确定皮瓣的潜在测量值（面积、周长、最大前后距离和最大横向距离）。
女性和男性皮瓣的平均面积分别为11.8平方厘米和12.7平方厘米。女性和男性的平均周长分别为13.5厘米和14.0厘米。在所有病例中，皮瓣均到达颞下窝和斜坡下部。
本研究中描述的经软腭腭瓣在尸体和断层扫描研究中被证明是一种在鼻内手术以及颅底和邻近区域使用的尺寸可行的替代方法。
