We can detect the SLN and lymphatic flow near to tumors without shine-through effect, especially in the head and neck regions. It is thought that CTLG may be useful to determine the range of lymph node dissection.

Bone marrow attracted our attention as a potentially beneficial material for the treatment of wounds, because it contains multipotential progenitor cells and produces growth factors. We impregnated autologous bone marrow cells on to a collagen matrix that had been used for the treatment of chronic wounds. The bone marrow-impregnated collagen matrix was then as a biomaterial scaffold for the treatment of wounds. This study was designed with the aim of clinically evaluating the effects of bone marrow-impregnated collagen matrix on wound healing of venous ulcers. We applied the matrix in 15 patients with chronic venous ulcers, and evaluated the transcutaneous oxygen tension (TcPO(2)) and vascular density. The application of the matrix induced healthy granulation tissue. All patients were given a split-thickness skin graft on to the induced granulation tissue, and have remained free from complications for more than eight months since the treatment. The mean (SD) vascular density at the ulcer base increased after the treatment (before 0.011 (0.006) mm(2)/mm(2), after 0.064 (0.036) mm(2)/mm(2), p < 0.001). The periwound TcPO(2) values tended to increase (before 17.1 (12.7) mmHg, after 30.6 (13.4) mmHg, p < 0.001). Our results have shown the efficacy of bone marrow-impregnated collagen matrix for the treatment of intractable venous ulcers.

In situ splitting of rib bone graft was conducted in 22 patients for the repair of orbital fracture with no other complicating fractures. A bone graft was harvested from the sixth or seventh rib in the right side. The repair of the orbital floor and medial wall was successful in all the cases. Ten patients had bone grafting to the orbital floor, eight had it done onto medial wall, and 4 onto both floor and wall after reduction. The mean length of in situ rib bone graft was 40.9 mm (range, 20-70 mm), the mean width of these was 14.9 mm (range, 8-20 mm). The bone grafting was done by one leaf for 15 cases and two leafs for 7 cases in size of defects. The technique of in situ splitting of a rib bone graft for the repair of the orbital floor and medial wall is a simple and safe procedure, easily taking out the in situ splitting of a rib, and less pain in donor site. It has proved to be an optimal choice in craniofacial reconstruction, especially the defects of orbital floor and medial wall.

This method is a simple and correct repositioning method without interfering with reconstructive and microsurgical procedures. We propose this technique as a reliable method for obtaining a functional outcome in mandibular reconstruction. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1708-1716, 2016.
