Aim:
In the present study, we investigated effects of a local anesthetic, in the treatment of pathologic scars.
Materials And Methods:
this retrospective report describes our experience with 97 patients who underwent lidocaine 2% injections in surgical scars of the hand. The results were evaluated using 4 parameters: cutaneous structure, pain, thikness and colour of the scar.
Results:
The mean outcome was the pain control. 2 out of 97 showed a 100% improvement in all the parameters. In 95 of 97 patients the improvement was between 60-100%.
Discussion:
Lidocaine controls different pathways of inflammation. Flogosis is the first phase of cicatrization and so lidocaine could be used in the treatment of pathologic scars. A previous study confirms the role of lidocaine, injected to control the pillar pain in the carpal tunnel's surgery in the improvement of scars.
Conclusion:
Lidocaine, as neuromodulation treatment, acts on inflammation, temperature, perfusion and partial pressure of oxygen.
