The 1996 Clinical Research award. Use of a pneumatonometer in burn scar assessment.
The evaluation of wound outcome after burn injury is a challenging problem in the performance of clinical trials evaluating potential impact on wound healing and scar formation. The purpose of this study was to determine whether an ocular tonometer could be adapted to provide an objective measurement of scar compliance. A pneumatonometer was used to perform measurements of cutaneous compliance at 8 anatomic areas (14 separate sites) on each of 17 normal volunteers and on 59 burn scars. Comparison of different anatomic sites showed there to be significant differences in the cutaneous compliance of different areas. The aggregate compliance of the burn scars in all sites was less than that of the control sites. These results indicate that the pneumatonometer can discern differences in the compliance of normal skin and differences between normal skin and scar and suggest that it may be a useful tool in the objective assessment of scar formation.
