We evaluated a new long (10 ms) pulsed erbium-YAG laser in order to determine safety and clinical efficacy in comparison with a pulsed carbon dioxide laser.\u0000\u0000\u0000OBJECTIVE\u0000Our objective was to comparatively evaluate a pulsed CO2 and long-pulsed erbium-YAG laser with regard to clinical side-effects, postoperative healing and efficacy in the reduction of rhytids.\u0000\u0000\u0000METHODS\u0000Bilateral periocular or perioral sites were treated using a pulsed CO2 (UltraPulse) laser on one side and long-pulsed erbium-YAG laser (CO3) on the opposite side. Histologic specimens were also studied in order to compare tissue effects of both lasers.\u0000\u0000\u0000RESULTS\u0000Results showed equivalent postoperative healing and lack of complications. In addition, the long-pulsed erbium-YAG laser showed significant efficacy in the treatment of mild and moderate rhytids.\u0000\u0000\u0000CONCLUSION\u0000The long-pulsed (10 ms) erbium-YAG laser appears to be of significant benefit in the treatment of facial rhytids. Tissue studies show a greater degree of thermal damage in the dermis when compared to traditional 350 microseconds erbium-YAG lasers which may underlie the beneficial effects of this laser in the treatment of aging skin.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"1 4 1","pages":"197-202"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628839950516670","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combining skin resurfacing with other procedures, especially the use of filling agents, has proven to be superior to the use of a single modality. Carbon dioxide laser resurfacing has been popularized for the treatment of acne scarring, but post operative morbidity with stimulation of active acne has been problematic. Conventional erbium resurfacing is effective when sufficient fluences are used, particularly when treating relatively superficial acne scars. Deeper resurfacing for acne scars is difficult with erbium lasers, owing to bleeding and heavy exudation, which decreases ablation efficiency and makes 'end points' difficult to visualize. The newer modulated hybrid erbium/CO2 lasers (Derma K, ESC Sharplan, Yokneam, Israel) produce efficient ablation by the reduction of bleeding, yet at the same time incur little post operative morbidity. This is suitable for treating deeper acne scars, and may be combined with other procedures, e.g. fat grafting. Of particular importance is the lack of acne stimulation associated with the use of the erbium/CO2 hybrid lasers.\u0000\u0000\u0000RESULTS\u0000In my series of 78 patients, improvement in acne scarring was > 70% in the majority of patients.

Surgery with other adjunctive methods including radiotherapy, intralesional steroids and pressure therapy have shown variable results. Laser treatment has been attempted for scar revision since the 1980s. The continuous wave lasers, including continuous wave carbon dioxide (CO2), argon and Nd:YAG achieved some improvement; however, their use was limited by the inherent problems of continuous mode lasers. The pulsed dye laser has been successfully used in erythematous and hypertrophic scars. Pigment-specific Q-switched lasers have shown a good improvement for pigmented scars. Skin resurfacing lasers (both CO2 and erbium-YAG) have been used successfully to improve selected atrophic facial scars.

This method has effectively replaced chemical peel and dermabrasion as modes for skin rejuvenation, yet surprisingly, very little has been published on its effectiveness. Our aim is to delineate clear indications, methods and results of laser skin resurfacing. Laser resurfacing has evolved over the past 13 years and our current method has emerged from this experience. This method has been employed on 258 consecutive patients treated over the past 2 years. A total of 201 patients were treated for photodamaged skin, 53 for facial acne scarring and four for post-surgical scars. Each of these conditions has in common the pathological finding of contour irregularity of the involved abnormal skin. The CO2 Ultrapulse laser's advantage is the predictable ability to vaporize the upper layer of elevated skin, tighten collagen bundles and induce a local inflammatory reaction with epithelial proliferation. This paper presents a clear, concise, and conservatively oriented technique, including pre- and post-operative care of laser skin resurfacing. The technique presented is conceived to correct precisely the underlying pathological condition and can be used in conjunction with other cosmetic procedures. A total of 200 patients underwent full face resurfacing, 41 periorbital, 13 perioral and four for facial scars. Of the patients, 78% were female and 22% were male. The results of each patient were judged by an independent observer. Some 92% were found to have either an excellent or very good result; 2% were judged to be satisfactory; and 6% were from outside the region or were lost to follow-up. Minor complications included 12% transient post-inflammatory hyperpigmentation, 3% acute acne and 1% herpes type 1. There were no major complications, including hypertrophic scarring. A total of 15% required some type of secondary touch-up resurfacing. Our method of laser skin resurfacing offers a consistent method for dramatic improvement of facial skin quality for those patients with photodamage and acne scarring, while minimizing risk.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"1 2 1","pages":"87-94"},"PeriodicalIF":0.0,"publicationDate":"1999-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628839950516913","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59799347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In demonstrating their efficacy, intra- and interoperator variability may be important. In attempting to solve this problem, a new concept was developed which combines a previous application of an exogenous chromophore onto the skin in a standardized way (Chromofilm) and irradiation with a millisecond, low-power pulsed laser. MATERIALS AND METHODS This study aimed to evaluate this new concept in vivo in human skin using a 532-nm Nd:YAG laser connected to a scanner using the following parameters: 532 nm, 2W, 1-mm spot size, 30-mm2 hexagonal surface irradiation and 50-120-ms pulse duration. The laser irradiation was performed both 15 h and 1 h prior to the facelift procedure. Tissue samples were examined histologically to determine the injury depth using nitroblue-tetrazolium chloride (NBTC) staining, haematoxylin-eosin staining and Masson's staining. RESULTS Morphometric analysis of histological preparations showed that the depth of injury was dose-dependent: 50-ms pulse duration induced total epidermis ablation and fine dermal coagulation; 120-ms pulse duration induced dermal coagulation down to 120 microns. No residual carbon film was observed on histologic sections. CONCLUSION Laser skin resurfacing using a 532-nm laser irradiation after application of a carbon film transfer is an effective method for skin resurfacing. With this new galenic approach (Chromofilm), the control of all parameters (thickness, chromophore concentration and distribution) can be achieved to predict the thermal injury obtained after laser irradiation.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"1 3 1","pages":"159-66"},"PeriodicalIF":0.0,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628839950516814","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59799215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
