  • Microsoft Kinect V2 as an alternative grading system for facial paralysis

    Grading systems for evaluating facial movements in facial paralysis can be classified into traditional and computer-based grading systems. Traditional systems are subjective systems, and the results can only be approximate. Computer-based grading systems provided quantitative repeatable results, they required significant time for manually using software and required high cost which limited their widespread clinical use. Recently, three-dimensional depth cameras in commercial gaming systems have been common, and reduced their cost. This study presents the results of using Microsoft Kinect V2 sensor for grading facial paralysis.
    The facial grading system software was implemented using Kinect for windows SDK 2.0. The software program was written by the author in Visual C#.
    For facial paralysis patient with synkinesis, after the botulinum toxin injections, the synkinetic eye closure movements improved both clinically and also in our facial grading system software.

    To develop hybrid artificial nerve conduits, biodegradable artificial nerve conduits made from woven polyglycolic acid (PGA) filled with collagen fibers were used. Gelatin hydrogel containing basic fibroblast growth factor (bFGF) and adipose-derived stem cells (ASCs) was put into PGA-collagen tube. Some lateral holes were made on the tube and condition of the gelatin hydrogel and artificial nerve ware observed.In clinical cases, artificial nerves were applied to nerve gaps of peroneal nerve without any complications. Autologous nerve grafts were used in facial nerve, hypoglossal nerve and recurrent laryngeal nerve. Comprehensive surgical treatment of facial paralysis including facial nerve reconstruction, nerve crossover and static procedures was analyzed.

    Hypertrophic Scar is a condition where high accumulation of collagen can be seen which is promoted by the excessive wound healing process. Main factors causing hypertrophic scar are (1). stretching force of wound site and (2). inflammation of wound. Although we tried to investigate the interaction between fibroblasts and dendritic cells under stretched condition, the research did not work well. However, meanwhile, we found the interaction between keratinocyte and fibroblasts under cyclic stretched condition. It is known that keratinocytes secret Endothelin-1 in response to the stretching force. In our study, cyclic stretching force is found to enhance the expression of Endothelin Receptor B and its coupling ion channel; TRPC3 and the sensitivity to Endothelin -1 signaling is increased. These findings suggest that the interaction between fibroblasts and keratinocytes during the wound healing process contribute to the formation of hypertrophic scar.

    In 10 rabbits, four branches of facial nerve were experimentally sectioned and reconstructed with cable grafts and end-to-side nerve graft with epineural suture and partial neurectomy. Morphological investigation showed that regenerating axons of the facial nerve trunk regenerate into each distal branches.
    The technique was applied in 3 patients and satisfactory functional recovery was obtained.

    We have compared the histological appearance of bone ablation and healing response in rabbit radial bone osteotomy created by surgical saw and ytterbium-doped fiber laser controlled by a computer and manually. The output power of the laser was 60W at the scanning speed of 20mm/sec scan using continuous wave system. Bone osteotomy was performed by an ytterbium-doped fiber laser and a surgical saw. Additionally, histological analyses of the osteotomy site were performed on day 0 and day 21. Ytterbium-doped fiber laser osteotomy revealed a remarkable cutting efficiency. Lased specimens have shown no delayed healing compared with the saw osteotomies. The output power of the laser was 20W and 30W using continuous wave system with a manual ablation. Those osteotomies revealed also a remarkable cutting efficiency.
