To probe the possibility of trans-sutural distraction osteogenesis for correction of children midfacial hypoplasia.
The trans-sutural distraction system of mid-facial skeleton consisted of the bone-borne traction hooks of titanium, the face-bow, and the elastic loops. Nine children with midfacial hypoplasia were treated at their 6 - 12 years of age. No osteotomy was made in them. Bone holes were drilled with a dental bur at each side of the lateral-inferior rim of the aperture, or at the anterior part of the hard palate. The traction device was hatched to the holes through the nostrils. Protraction began 3 days postoperatively, with the forces adjusted dependently upon the rate of progress. When the skeleton reached to the planed position, it was retained with a minor force for 8 weeks.
The mid-facial skeleton of the nine children showed a balanced advancement. Their facial profile and cross-bite were corrected satisfactory.
Patients with severe mid-facial hypoplasia could be corrected ideally by the new technique, with minor trauma, easy manipulation. The design of protraction system was reasonable.
探讨经缝合牵引成骨术矫正儿童面中部发育不全的可能性。
面中部骨骼经缝合牵引系统由钛制骨传导牵引钩、面弓和弹性环组成。9例6至12岁面中部发育不全的儿童接受了治疗。术中未进行截骨术。在眶下外侧缘两侧或硬腭前部用牙钻钻孔。牵引装置通过鼻孔固定在孔上。术后3天开始牵引，根据进展情况调整力量。当骨骼达到计划位置时，用较小的力量维持8周。
9例儿童的面中部骨骼均呈现出均衡前移。面部轮廓和反咬合得到了满意的矫正。
新技术可理想地矫正重度面中部发育不全患者，创伤小，操作简便。牵引系统设计合理。
