Disjunction of the nasofrontal junction was performed under endoscopic control in three patients who underwent a monoblock nasal framework osteotomy and two patients who underwent a modified Le Fort type II osteotomy through a small midscalp incision, a stub wound at the root of the nose, and an intercartilaginous incision. A bilateral intercartilaginous incision and nasal root stub wound were used in one case. An osteotomy of the nasal root was performed using a specially designed detachable osteotomy consisting of a thin staff and large handle. The end of the staff was inserted through the access incision and pulled through a stub wound created in the nasal root. The staff was then attached to the handle, and the osteotomy was performed under endoscopic control. This approach minimizes the surgical scar, the area of the subperiosteal dissection, and postoperative swelling of the face, in comparison with the coronal approach.
在3例行整块鼻框架截骨术的患者以及2例行改良Le Fort II型截骨术（通过头皮中部小切口、鼻根处短切口和软骨间切口）的患者中，在内镜控制下进行鼻额交界处分离。1例采用双侧软骨间切口和鼻根短切口。使用一种专门设计的可拆卸截骨工具进行鼻根截骨，该工具由细杆和大手柄组成。将杆的末端通过入路切口插入，并从鼻根处制造的短切口穿出。然后将杆连接到手柄上，在内镜控制下进行截骨。与冠状入路相比，这种方法可将手术瘢痕、骨膜下剥离面积和面部术后肿胀降至最低。
