Methods: From 1995 to 2005, 87 children (aged 1. 2 to 14 years) with moderate and severe glottic and subglottic stenosis were retrospectively studied. They were operated with cricoid spliting laryngotracheal reconstruction in our hospital. All of 87 patients were tracheostomy-dependent before surgery. Results: Eighty-five patients (95%) were successfully decannnulated and got an effective phonation. The follow-up time was more than 5 years. The effect of operation was satisfactory and the growth and development of children was normal. Conclusion: Anteroposterior cricoid split interposition costal cartilage graft is a safe and effective treatment method for moderate and severe glottic and subglottic stenosis in children.展开更多

Methods: Thirty cases of fresh transcervical and subcapital fractures of the femoral neck were treated by the tail breakable screws and sartorius pedicle bone grafts (single muscular pedicle, SMP group). The other 23 cases were treated by cannulated pressure screws and bone grafts with the muscular pedicles of both sartorius and tensor fasciae latae (double muscular pedicles, DMP group). Results: Fifty-two cases were followed up for 3 to 5 years (mean, 4 years). In SMP group, ten cases showed poor therapeutic results. Excellent therapeutic effects were achieved in all cases of DMP group. Conclusions: The transcervical or subcapital fractures of the femoral neck can be treated by double muscular pedicles bone graft. The bone graft with double muscular pedicles is more effective than single sartorius muscular pedicles for fresh transcervical and subcapital fractures of the femoral neck during short and medium terms.展开更多

Methods: From March 1988 to February 1998, 30 patients with long bone defects over 6 cm in length received vascularized fibular graft including a monitoring island flap in our department to monitor the blood circulation of the fibulae. Results: Monitoring island abnormalities were indicated in 6 flaps, which accurately gave the alarm of the circulation crisis of the fibular graft. Surgical exploration was performed timely and the blood supply was recovered instantaneously. All the bone defects were healed at 6 months postoperatively. After 4 years of follow up, all the grafted fibulae were thickened and were just like tibiae. Conclusions: A monitoring island flap is a satisfactory method for repairing large defects of the long bones and a reliable method for assessing the vascular status of the grafted fibulae.展开更多
