Studies from our own laboratory demonstrate that collagenase-1 expression in wound edge keratinocytes is rapidly turned on following injury.35 The experimental procedure that we used involves normal human skin obtained from plastic surgery, wounded ex vivo, kept in culture, and harvested at different time-points. The earliest time point studied shows evidence of collagenase mRNA at 4 hours after wounding (Fig. 12.1), perhaps collagenase expression is an immediate response to injury that occurs even earlier. Examining these healing wounds we found that the peak expression of collagenase-1 occurred at 12-24 hours and remained high until day 2, when expression began to decrease. Over the next few days collagenase expression was less intense but persisted until the migrating keratinocytes had covered the unprotected surface. Thus, our studies demonstrate that in these acute wounds, collagenase-1 levels mirror the re-epithelialization process, which is complete in 5-7 days. In fact, when...
Indications for the use of Gore-Tex have expanded. The evolution from abdominal wall patch to use in facial augmentation and reconstruction blossomed during the early to mid-1980s. SAM is identical to the soft tissue patch and is used specifically for facial plastic and reconstructive surgery. Gore-Tex implants have been used for a myriad of applications in facial plastic surgery but have found significant success when used to augment the nasal dorsum.14,56-61 Because of its natural appearance and ease of use as compared with rib cartilage or other autolo-gous implants, Gore-Tex has become popular as a nasal implant.
