为了减少再狭窄的可能性，已经开发了几种类型的皮瓣技术来覆盖draft手术后暴露的骨。这些技术相对较新，随访期间对新开口大小的详细测量尚未见报道。作者的目的是准确地评估结果，不仅使用内窥镜评估，而且通过测量口的直径和鼻喙的厚度在术前和术后的计算机断层扫描图像。作者回顾了25例37个鼻腔患者，他们接受了draft手术，采用了先前报道的上外侧前蒂皮瓣技术。分别于手术前、手术后及术后6个月及以上测量额窝的前后距离及鼻喙的厚度。测量距离进行统计学分析。在所有患者的长期随访中，新开口均保持通畅。在随访中保留了额隐窝的AP距离和鼻喙的厚度。眼眶和眶部均未发生损伤。总之，采用上外侧前蒂皮瓣的draft II型和III型手术是安全有效的。Neo-Ostia在整个随访期间保持专利。
Several types of flap techniques have been developed to cover exposed bone after Draf procedures to reduce the possibility of re-stenosis. These techniques are relatively new and detailed measurements of the size of neo-Ostia during follow-up have not been reported. The authors aim to assess outcomes precisely by not only using endoscopic evaluation but also by measuring the diameter of the ostium and the thickness of the nasal beaks on pre- and postoperative computed tomography images. The authors reviewed 25 patients with 37 nasal cavities who have undergone a Draf surgery with a previously-reported superior lateral anterior pedicle flap technique. The anteroposterior (AP) distance of the frontal recess and the thickness of the nasal beaks were measured before, immediately after, and more than 6 months after surgery. Measured distances were statistically analyzed. The neo-ostium remained patent in long-term follow-up of all patients. The AP distance of the frontal recess and the thickness of the nasal beak were preserved during follow-up. Neither synechiae nor orbital injuries occurred. In conclusion, Draf type II and III procedures with superior lateral anterior pedicle flaps are safe and effective. Neo-Ostia remained patent throughout the follow-up period.
