Abstract
INTRODUCTION There is limited basic research on carbon dioxide (CO2 ) fractional laser, indicating blind spots in CO2 fractional laser treatment of certain diseases. This study aimed to organize previous literature, summarize the current research, and speculate on possible future development. METHODS We searched document data on fractional CO2 lasers from the Web of Science core collection database and retrieved 928 articles from 2004 to 2021. CiteSpace software was used to analyze the main institutions, authors, subject hotspots, and research frontiers in global CO2 fractional laser research. RESULTS The results revealed that 928 related papers were published in the past 18 years (2004-2021), and the number has increased annually. The publications were written by 3239 authors from 626 institutions in 60 countries/regions. The United States (US) dominates this field (312 documents), followed by Italy (289), and South Korea (88). Lasers in Surgery and Medicine is the journal with the most publications and citations, and Uebelhoer is the central author. The main research hotspots include vulvovaginal atrophy, fractional photothermolysis, keloids, drug delivery, gene expressions, facial acne scarring, resurfacing, vitiligo, and photo damage. CONCLUSION Using CiteSpace, this paper draws a map of authors, institutions, and keywords in fractional CO2 laser from 2004 to 2021; summarizes the main authors, institutions, research hotspots, and cutting-edge topics of global fractional CO2 laser technology in recent years; and summarizes the current application status of global fractional CO2 laser in disease treatment. It also provides new ideas for the future application and research of fractional CO2 lasers.

Hybrid fractional laser treatment for photodamaged facial skin rejuvenation 6 years following fractional CO 2 : Comparison of clinical outcome and patients' satisfaction. Lasers Surg Med Suppl 2022; 54:1045-1050. [PMID: 35819131 DOI: 10.1002/lsm.23583] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 05/09/2022] [Accepted: 06/26/2022] [Indexed: 01/20/2023]
Abstract
OBJECTIVES Fractional carbon dioxide (CO2 ) laser resurfacing is considered an effective treatment for skin rejuvenation. The request for clinical effectiveness with shorter downtime has led to the development of new hybrid technologies, including a traditional Er:YAG (erbium-doped yttrium aluminium garnet) fractional laser 2940 nm combined with a simultaneous nonablative 1470 nm wavelength. The aim of this study is to compare clinical outcomes and patients' satisfaction with face resurfacing performed with both the CO2 laser and the hybrid laser. METHODS Nineteen women underwent ultrapulsed CO2 fractional resurfacing for photodamaged facial skin; the same patients underwent the hybrid laser after almost 6 years. Clinical outcomes and patients' satisfaction were evaluated 6 months after the treatment and compared between the two technologies. RESULTS After both CO2 and hybrid treatment a significant improvement was found in terms of fine lines (p < 0.001 and p = 0.004, respectively), tactile roughness (p < 0.001 and p = 0.002, respectively), and mottled pigmentation (both p < 0.001). Healing times and complications were greater with the CO2 laser. Comparing the two technologies, patients showed better results with the CO2 laser for each score's item, but greater satisfaction with the hybrid laser (p = 0.012). CONCLUSIONS The present study confirms CO2 laser as the most effective treatment; however, the new hybrid technology revealed good results associated with faster healing and less discomfort.

Abstract
Literature on lacrimal punctal tumors is limited due to their rarity. Our aim in this study was to evaluate the clinicopathological characteristics of these tumors and assess functional and aesthetic outcomes after CO2 laser ablation with silicone stent intubation. A retrospective consecutive study was conducted from December 2013 to November 2020. All patients who received CO2 laser ablation with silicone intubation for their punctal tumors at National Cheng Kung University Hospital, a tertiary hospital in Taiwan, were included in this study. Demographic and clinical information was gathered during preoperative and follow-up visits. Thirty-three Han Chinese patients with a solitary punctal tumor were included in this study. Demographically, we found a female predominance (75.8%), and most tumors were located at the lower punctum (69.7%). The incidence of melanocytic nevus was higher in punctal tumors (78.8%) than in benign eyelid tumors (22.3%). Irrigation tests were performed in the 33 patients during follow-up visits, all of whom exhibited patency of the lacrimal system. No patient complained of epiphora after surgery. Thirty-two patients (97%) were satisfied with the aesthetic outcome after surgery. Superpulse CO2 laser ablation followed by silicone stent intubation is a safe and effective treatment for benign punctal tumors. In addition, compared to those of eyelid tumors, the clinicopathological characteristics of lacrimal punctal tumors are different, and melanocytic nevus was the main cause of these tumors.

Abstract
BACKGROUND AND OBJECTIVES Skin photoaging is related to extrinsic environmental exposures, mainly represented by ultraviolet radiation. One of the treatment options is laser resurfacing. As nutritional status is involved in cutaneous photodamage, we evaluated whether dietary patterns can also influence the response to facial resurfacing. Our prospective multicentric study involves three dermatologic centers specialized in laser therapy in northern Italy. The study aims to compare the outcome of a CO2 ablative laser therapy between omnivore and vegan patients. STUDY DESIGN/MATERIALS AND METHODS Fifty-three omnivore and fifty-three vegan women undergoing ultrapulsed CO2 resurfacing for photodamaged facial skin were enrolled in this study. Clinical improvement was evaluated 3 and 6 months after the treatment using the modified Dover score. RESULTS After laser treatment, vegans showed slower complete re-epithelialization (P < 0.001*) and disappearance of the erythema (P < 0.001*). After 3 and 6 months, vegans showed worse outcomes in terms of fine lines (P < 0.001* and P < 0.001*, respectively) and tactile roughness (P = 0.003* and P = 0.002*, respectively) compared with omnivores, while they did not differ in mottled pigmentation. CONCLUSIONS The present study suggests that diet influences the clinical outcome of fractioned CO2 laser treatment. Lasers Surg. Med. © 2021 Wiley Periodicals LLC.

Abstract
PURPOSE To evaluate the effect of fractional carbon dioxide (CO2) laser treatment using lower power associated with pulse stacking within collagen fibers, using second harmonic generation microscopy and computerized image analysis. METHODS Twenty male Wistar rats aging eight weeks were used. Each treatment area received a single-pass CO2 fractional laser with different parameters. The 20 animals were divided into two groups and euthanized after 30 and 60 days. Second harmonic generation images were obtained and program ImageJ was utilized to evaluate the collagen organization within all areas. Collagen anisotropy, entropy and optical density were quantified. RESULTS Increased anisotropy over time was observed in all four areas, but only reached statistical significance (p = 0.0305) when the mildest parameters were used (area four). Entropy decreased over time in all areas, but without significance(p = 0.1779) in area four. Density showed an overtime increase only in area four, but no statistical significance was reached (p = 0.6534). CONCLUSIONS When combined, the results obtained in this study regarding anisotropy, entropy and density tend to demonstrate that it is possible to achieve collagen remodeling with the use of lower power levels associated with stacked pulses.

Abstract
OBJECTIVE The purpose of this study is to review the differences between continuous wave (CW) and UltraPulse (UP) on thermal damage of the laser with different power. METHODS Four adult beagle dogs underwent transoral laser microsurgery (TLM) using CO2 laser. The laser emission mode and power was CW (3 W, 5 W, and 8 W) and UP (3 W and 5 W), respectively. The tissue from 4 animals was evaluated histologically on postoperative days 1 and 3. The thermal damage of the laser was measured using slide scan system via SlideViewer version 1.5.5.2 software. RESULTS All dogs underwent TLM uneventfully. Under microscope examined, the laser damage area was composed of 2 parts: the vaporized zone (VPZ) and thermal damage area. The thermal damage area can be divided into thermal coagulative necrosis area (TCN) and hydropic degeneration area. The width of VPZ and TCN in UP mode was less than that in CW mode (P < .01). The data indicate that lower laser power created less thermal damage (P < .01). In addition, the width of VPZ on postoperative day 3 was less than that on postoperative day 1 (P < .01). CONCLUSION CO2 laser with UP and lower power could decrease the laser thermal damage and may offer more prompt wound healing.

Mirza HN, Mirza FN, Khatri KA. Outcomes and adverse effects of ablative vs nonablative lasers for skin resurfacing: A systematic review of 1093 patients. Dermatol Ther 2020; 34:e14432. [PMID: 33084193 DOI: 10.1111/dth.14432] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 09/20/2020] [Accepted: 10/12/2020] [Indexed: 12/17/2022]
Abstract
It is generally believed that ablative laser therapies result in prolonged healing and greater adverse events when compared with nonablative lasers for skin resurfacing. To evaluate the efficacy of ablative laser use for skin resurfacing and adverse events as a consequence of treatment in comparison to other modalities, a PRISMA-compliant systematic review (Systematic Review Registration Number: 204016) of twelve electronic databases was conducted for the terms "ablative laser" and "skin resurfacing" from March 2002 until July 2020. Studies included meta-analyses, randomized control trials, cohort studies, and case reports to facilitate evaluation of the data. All articles were evaluated for bias. The search strategy produced 34 studies. Of 1093 patients included in the studies of interest, adverse events were reported in a total of 106 patients (9.7%). Higher rates of adverse events were described in nonablative therapies (12.2% ± 2.19%, 31 events) when compared with ablative therapy (8.28% ± 2.46%, 81 events). 147 patients (13.4%) reported no side effects, 68 (6.22%) reported expected, transient self-resolving events, and five (0.046%) presented with hypertrophic scarring. Excluding transient events, ablative lasers had fewer complications overall when compared with nonablative lasers (2.56% ± 2.19% vs 7.48% ± 3.29%). This systematic review suggests ablative laser use for skin resurfacing is a safe and effective modality to treat a range of pathologies from photodamage and acne scars to hidradenitis suppurativa and posttraumatic scarring from basal cell carcinoma excision. Further studies are needed, but these results suggest that ablative lasers are a superior, safe, and effective modality to treat damaged skin.

Abstract
PURPOSE To evaluate the effect of different energies and stacking in skin shrinkage. METHODS Three decreasing settings of a fractional CO2 laser were applied to the abdomen of Twenty five Wistar rats divided into three groups. Group I (n=5) was histologically evaluated for microthermal zones dimensions. Groups II and III (n=10 each) were macroscopic evaluated with freeware ImageJ for area contraction immediately and after 30 and 60 days. RESULTS No statistical significance was found within microthermal zone histological dimensions (Group I) in all settings studied. (Ablation depth: 76.90 to 97.18µm; Coagulation depth: 186.01 to 219.84 µm). In Group II, macroscopic evaluation showed that all settings cause significant immediate skin contraction. The highest setting cause significant more intense tightening effect initially, contracting skin area from 258.65 to 179.09 mm2. The same pattern was observed in Group III. At 30 and 60 days, the lowest setting significantly sustained contraction. CONCLUSION Lower fractional CO2 laser energies associated to pulse stacking could cause consistent and long lasting tissue contraction in rats.
