Abstract Aim of the work To study prognostic value of thermography in cases of peripheral nerve injuries and after nerve sutures. Comparative study with available methods of investigations e.g. electromyography and nerve conduction studies was done searching for reliability of thermogram in diagnosis of early regeneration after nerve suture. Conclusion With direct measurement of skin temperature at segments corresponding to known distribution of peripheral nerve, thermography allows quantitation of change in, as well as demarcation of the area affected by peripheral nerve injury. Also, it can recognize early regeneration after nerve suture. Thermal changes (hypothermia in chronic nerve injuries), caused by loss of vascular control and trophic changes begin to regress and approach the normal corresponding side. The diagnosis of early regeneration after nerve suture, reached by LCT is of high significance (80% in our study), where LCT has shown early regeneration after nerve suture before any apparent clinical or electrical signs of regeneration. The results reached in this study are strongly indicating that thermography is a reliable and useful investigation concerning nerve injuries and there is no overwhelm in saying that thermography is a very sensitive test in diagnosis of peripheral nerve injuries and of the highest prognostic value for follow up after nerve suture. |
