Abstract

Objective: 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.

Methods: 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).

Results: 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.

Conclusion: 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.

改良腭瓣经软腭重建颅底。

目的：考虑到带血管皮瓣的重要性，本研究提出了一种经软腭带蒂腭瓣重建颅骨缺损的新技术。方法：采用5个保存完好的尸体标本，展示了腭瓣摘取的顺序步骤。此外，对20例正常鼻窦计算机断层扫描进行分析，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）。结果：女性和男性皮瓣平均面积分别为11.8cm2和12.7cm2。雌性和雄性的平均周长分别为13.5cm和14.0cm。在所有病例中，皮瓣到达颞下窝和下斜坡。结论：本研究中描述的通过软腭的腭瓣在尸体和断层扫描研究中被证明是一种可行的替代方法，可用于鼻内手术，以及颅底和邻近区域。
