Abstract：
UNASSIGNED: To describe a novel method of medial fixation of titanium mesh with a right-angled screwdriver for orbital floor and maxillary reconstruction and to compare the reconstruction outcome of orbital floor reconstruction with modified and traditional methods.
UNASSIGNED: The data of 23 patients who underwent maxillectomy and orbital floor defect reconstruction by individualized titanium mesh in Peking University School and Hospital of Stomatology between 2018 and 2021 were retrospectively reviewed. While eight patients received modified orbital floor reconstruction with titanium mesh and angled screwdriver (group A), 15 patients received traditional orbital floor reconstruction (group B). The contact area with buccal flap for titanium mesh in groups A and B was calculated. Titanium mesh deformation, fracture or exposure was recorded. Postoperative ophthalmic function and success of esthetic restoration were assessed.
UNASSIGNED: Mean follow-up was for 15.7 months (range, 9-22 months). The contact area with buccal flap for the modified titanium mesh in group A (13.11 ± 1.41 cm2) was significantly less than that of the traditional titanium mesh in group B (21.83 ± 1.23 cm2; p < .05). The exposure of titanium mesh occurred in two patients in group B. The self-evaluation of facial symmetry for 23 patients showed no significant difference between group A (7.75 ± 0.71) and group B (6.68 ± 1.30; p > .05). No specific complications were reported.
UNASSIGNED: We propose a novel method of zygomatic medial fixation of titanium mesh with a right-angled screwdriver for orbital floor and maxillary reconstruction, which has the potential to prevent the postoperative exposure of titanium mesh.
UNASSIGNED: Level III (Retrospective comparative study).

摘要：
■描述一种用直角螺丝刀对钛网进行内侧固定的新颖方法，用于眶底和上颌骨重建，并比较改良和传统方法对眶底重建的重建结果。
■回顾性分析2018年至2021年北京大学口腔医院23例采用个体化钛网进行上颌骨切除及眶底缺损重建的患者资料。8例患者接受钛网和斜角螺丝刀改良眶底重建术（A组），15例患者接受传统眶底重建术(B组)。计算A组和B组钛网与颊瓣的接触面积。钛网变形，记录骨折或暴露。评估术后眼功能和美学恢复的成功。
■平均随访15.7个月（范围，9-22个月）。A组改良钛网与颊瓣的接触面积（13.11±1.41cm2）明显小于B组传统钛网（21.83±1.23cm2；p<0.05）。B组中有2例患者出现钛网暴露。23例患者的面部对称性自我评估在A组（7.75±0.71）和B组（6.68±1.30；p>0.05）之间无显着性差异。没有具体的并发症报告。
■我们提出了一种新颖的方法，用直角螺丝刀对钛网进行zy骨内侧固定，用于眶底和上颌骨重建，有可能防止钛网术后暴露。
■III级（回顾性比较研究）。
