Use of a fractional 1570-nm diode laser scanner for non-ablative face and neck rejuvenation.

BACKGROUND: The use of non-ablative fractionated lasers for skin rejuvenation has been proven to be effective in improving skin texture, and has become popular due to minimal wounding, significantly shorter recovery times and decreased adverse effects. OBJECTIVE: To retrospectively analyze improvement in skin texture in healthy women aged over 18 years with Fitzpatrick skin types II-IV. METHODS: Participants received three facial and/or neck treatments with the 1570-nm fractional scanning diode laser at 1-month intervals. Three months after the last treatment session two blinded evaluators assessed skin improvement using before and after photos. Pain and patient satisfaction were recorded. RESULTS: Sixteen women with a mean age of 45.4 ± 4.1 years (range 35-50 years) and skin type II-IV were included in the analysis. All 16 participants received facial treatments and seven (43.8%) also received neck treatments. Three months follow-up evaluation showed that the majority of participants had a visible change in the treated areas. Mean pain score was low and decreased with each treatment session. CONCLUSION: Skin treatment using fractional scanning 1570-nm diode laser improves skin laxity in women with skin types II-IV. Larger studies are warranted to further clarify the efficacy and safety of this modality.

Study on the efficacy and safety of a high-power triple wavelength diode laser (810, 940, 1060 nm) for removing fine and less pigmented facial hair on Asian skin.

INTRODUCTION: Performing laser hair removal treatments on dark skin is limited by the quantity of melanin within the skin. To minimize side effects, lower values of fluence are selected when using standard 755 or 810 nm diode lasers. However, this approach may limit the effectiveness of the procedure, particularly when treating areas with thin and less pigmented hair, which is often the case in facial regions. To improve results, high-power triple wavelength diode lasers can be used. This study aims to assess the efficacy, safety, and comfort of treatments that remove facial hair with a high-power triple wavelength diode laser (810, 940, and 1060 nm) in static mode on Asian patients with thin and less pigmented hair. MATERIALS AND METHODS: A single-center retrospective cohort study was carried out using a high-power triple wavelength diode laser (810, 940, and 1060 nm), with a 2.7 cm2 spot size, on faces with thin and less pigmented hair. The study comprised 23 subjects with Fitzpatrick skin types IV and V. Effectiveness was measured by counting the hairs that appeared in high-resolution photos taken prior to and following the procedure, in addition to the Global Aesthetic Improvement Scale (GAIS). Furthermore, mathematical 3D simulations were created on the COMSOL Multiphysics® software to allow for comparisons to be made with regard to thermal damage sustained by the hair follicles and epidermal heating. Assessments were also made in relation to side effects. RESULTS: An average of 66% hair reduction was observed. Patient satisfaction was between 4 and 5 points on the GAIS scale, indicating that the treatment was very well received and tolerated. Adverse side effects were not observed. CONCLUSION: It can be concluded that the use of a high-power triple wavelength diode laser (810, 940, and 1060 nm) is safe and effective for the treatment of very fine and less pigmented facial hair on Asian skin. Furthermore, a triple wavelength (810, 940, and 1060 nm) laser is absorbed less by the melanin in the skin, enabling the use of higher fluences in stamping mode, with greater efficacy and safety for darker skin.

Is multiple wavelength diode laser for facial contouring safe?

The multiple wavelength diode laser (MWDL) is a sophisticated device designed to target deeper skin layers by emitting various wavelengths. Its unique feature is the ability to deliver heat to specific depths within the tissue using different wavelengths while simultaneously cooling the skin surface. Recent research by Choi et al. suggests that wavelengths of 755 and 810 nm can induce carbonization in hair follicles, while the 1064 nm wavelength penetrates deeper into tissues. MWDL has been proposed for fat redistribution in aging, but concerns have been raised regarding ocular safety and potential tissue damage, particularly when used near the eyes. Studies have shown ocular injuries during cosmetic laser procedures, emphasizing the need for robust ocular protection and safety protocols. Additionally, there are reports of internal ischemic necrosis and burns, highlighting the importance of precise energy settings and parameter management. While MWDL shows promise, further research and comprehensive guidelines are needed to ensure safe and effective usage in clinical practice.

Comparative analysis of the safety and efficacy of 1470-nm diode laser enucleation of the prostate and plasmakinetic resection of prostate in the treatment of large volume benign prostatic hyperplasia (>80 ml).

OBJECTIVE: To compare the efficacy and safety of 1470-nm diode laser enucleation of the prostate (DiLEP) with that of plasmakinetic resection of the prostate (PKRP) in treating patients with large benign prostatic hyperplasia (BPH > 80ml). METHODS: The clinical data from 211 cases of BPH (>80 ml) were collected for analysis. The patients were divided into two groups: the PKRP group (n = 118) and the DiLEP group (n = 93), based on the surgical method used. RESULT: The DiLEP group demonstrated significantly lower surgical time (p < 0.001), intraoperative bleeding (p < 0.001), bladder flushing time (p = 0.003), indwelling catheter time (p < 0.005), and length of hospital stay (p = 0.018) compared to the PKRP group. However, the quality of the prostatectomy was significantly higher in the DiLEP group (p = 0.005). The Qmax for the DiLEP group was significantly higher than that of the PKRP group (p < 0.05). Compared to the PKRP group, the incidence of urinary incontinence in the DiLEP group increased significantly 4 weeks post-surgery (p = 0.026), although the need for blood transfusion during surgery was significantly reduced (p = 0.037). CONCLUSION: Both DiLEP and PKRP are safe and effective methods for treating large-volume BPH. However, DiLEP offers advantages such as more thorough glandular resection, shorter surgical time, reduced bleeding, quicker recovery, and fewer complications.

Temperature changes in the pulp chamber and bleaching gel during tooth bleaching assisted by diode laser (445 nm) using different power settings.

The aim of this in vitro study was to investigate the safety of using blue diode laser (445 nm) for tooth bleaching with regard to intrapulpal temperature increase operating at different average power and time settings. Fifty human mandibular incisors (n = 10) were used for evaluating temperature rise inside the pulp chamber and in the bleaching gel during laser-assisted tooth bleaching. The change in temperature was recorded using K thermocouples for the five experimental groups (without laser, 0.5, 1, 1.5 and 2 W) at each point of time (0, 10, 20, 30, 40, 50 and 60 s). As the average power of the diode laser increases, the temperature inside the pulp chamber also increases and that of the bleaching gel was significantly higher in all the experimental groups (p < 0.05). However, the intrapulpal temperature rise was below the threshold for irreversible thermal damage of the pulp (5.6 °C). Average power of a diode laser (445 nm) ranging between 0.5-2 W and irradiation time between 10-60 s should be considered safe regarding the pulp health when a red-colored bleaching gel is used. Clinical studies should confirm the safety and effectiveness of such tooth bleaching treatments. The outcomes of the present study could be a useful guide for dental clinicians, who utilize diode lasers (445 nm) for in-office tooth bleaching treatments in order to select appropriate power parameters and duration of laser irradiation without jeopardizing the safety of the pulp.

Umbilical seborrheic keratosis-like lesion developing after diode laser hair removal in an 18-year-old patient.

OBJECTIVE: to report a possibly novel complication of laser hair removal. CASE REPORT: a white-skinned 18-year-old patient discovered an umbilical, brown, and raised lesion while shaving before his second diode laser hair removal session. He sought consultation before his fourth laser session since the lesion further thickened and darkened. Dermoscopy showed no pigmented network, but a few comedo-like openings within an erythematous-light brown scaly and fissured papule, "moth-eaten" borders, and a central crust due to manipulation, suggesting the diagnosis of seborrheic keratosis. We noted that the laser fluence was increased on the umbilical region where hair seemed resistant to treatment. The patient denied a recent history of local sun tanning, sunburns, inflammation, drainage, or manipulation. The lesion cleared, with no short-term relapse, after one session of cryotherapy. CONCLUSION: the development of a seborrheic keratosis-like lesion on a densely haired non-sun-exposed umbilicus of a young patient, following pre-laser shaving and high-fluence hair removal diode laser sessions, could have implicated triggering irritation and/or keratinocyte stimulation by red light-engendered reactive oxygen species (ROS) in the skin with silent epidermal mosaicism.

Microscopic, Macroscopic and Thermal Impact of Argon Plasma, Diode Laser, and Electrocoagulation on Ovarian Tissue.

BACKGROUND/AIM: To compare the microscopic, macroscopic and thermal damage inflicted to ovarian tissue by conventional monopolar and bipolar energy, argon plasma coagulation (APC) and diode laser. MATERIALS AND METHODS: Bovine ovaries were used as a substitute for human tissue and subjected to the four aforementioned techniques and the inflicted damage was measured. Sixty fresh and morphologically similar cadaveric bovine ovaries were divided into five equal groups, each group was subjected to one of the following energy applications for both 1 and 5 s: Monopolar, bipolar electrocoagulation, diode laser, preciseAPC® and forcedAPC® Ovarian temperatures were measured at 4 and 8 s after treatment. Formalin-fixed ovarian specimens were examined by pathologists regarding macroscopic, microscopic and thermal tissue damage. RESULTS: None of the ovaries reached the temperature producing severe damage (40°C) after 1 s of energy transfer. Heating of adjacent ovarian tissue was least pronounced when preciseAPC® and monopolar electrocoagulation were applied (27.2±3.3°C and 28.2±2.9°C after 5 s of application, respectively). Conversely, 41.7% of the ovaries subjected to bipolar electrocoagulation for 5 s overheated. ForcedAPC® resulted in the most pronounced lateral tissue defects (2.8±0.3 mm after 1 s and 4.7±0.6 mm after 5 s). When the modalities were applied for 5 s, the electrosurgical instruments (mono- and bipolar) and preciseAPC® induced similar lateral tissue damage (1.3±0.6 mm, 1.1±1.6 mm and 1.2±1.3 mm, respectively). preciseAPC® created the shallowest defect of all the techniques (0.05±0.1 mm after 5 s of application). CONCLUSION: Our study hints at superior safety profiles of preciseAPC® and monopolar electrocoagulation compared to bipolar electrocoagulation, diode laser and forcedAPC® for ovarian laparoscopic surgery.

Novel laser hair removal in all skin types.

BACKGROUND: Laser has been long accepted as a solution for excess or unwanted hair growth yet traditional lasers are not always ideal for safe and effective outcome for all skin types and hair characteristics. A diode laser module combining three wavelengths (755, 810, and 1064 nm) in a single pulse was developed to provide a fast and long-term solution for subjects with various profiles. AIMS: To evaluate the safety and efficacy of a Triple wavelength diode laser module for hair removal treatment in all skin types (Fitzpatrick I-VI). SUBJECTS AND METHODS: This was a prospective, dual centered, single-arm study. Subjects were treated with a novel diode laser module. Thirty-six subjects were enrolled, sixteen with Fitzpatrick skin types I-IV (46%) and twenty with Fitzpatrick skin types V-VI (54%). Treatment areas were axilla and bikini lines. Subjects underwent 4 treatment sessions at 6 weeks ± 5 days intervals and attended a follow-up visit 3 months after the last treatment session. 2D digital photographs were taken at baseline and at the follow-up visit, and a hair count was conducted by three blinded evaluators. RESULTS: A significant reduction in hair count between baseline and the 3-month follow-up visit was observed in both axilla and bikini lines for all skin types. The mean hair reduction was 41.5 ± 19.4% and 48.1 ± 20.9% in the axilla and bikini line, respectively. A significant hair reduction was also observed within skin type groups; mean hair reduction 45.5 ± 16.9% and 40.3 ± 17.2% in skin types I-IV and V-VI, respectively, indicating similar efficacy for both light and dark skin types. No serious adverse events were reported. CONCLUSIONS: This study demonstrates that the Soprano Titanium laser platform is safe and effective for hair removal treatment in all skin types.

The efficacy of laser haemorrhoidoplasty (LHP) in the treatment of symptomatic haemorrhoidal disease: An observational cohort study.

AIM: Laser haemorrhoidoplasty (LHP) is an emerging nonexcisional surgical procedure in which the arteriovenous flow of the haemorrhoidal plexus is interrupted through laser coagulation. The aim of this cohort study was to assess efficacy of LHP in treating symptomatic haemorrhoidal disease through patient satisfaction, remission of symptoms (blood loss, pain, itching, soiling, mucosal prolapse) and recurrence of haemorrhoids. METHODS: Patients who underwent treatment for symptomatic haemorrhoids (degrees 1-4) through an LHP procedure between 2015 and 2021 were included in the study. A 1470 nm-diode laser was used. A total of 200 patients (71% male, average age 51 years) were analysed. Primary outcomes were patient satisfaction and/or complete recovery of symptoms. Secondary outcomes were operating time, complications and recurrence rates. Patient satisfaction, postoperative blood loss, pain and complications were evaluated 6-7 weeks postoperatively. Room turnover time and operating time were documented. Recurrence of haemorrhoids following LHP treatment within 1 year was evaluated. RESULTS: Patient satisfaction regarding LHP treatment was reached in 155 (84,7%) patients. Postoperative blood loss was reported by 44 (24,0%) patients during time of evaluation. Twenty-four (13,1%) patients reported postoperative pain after 6-7 weeks. Postoperative complications occurred in seven patients (3 anal fissures, 2 perianal abscess, 1 perianal fistula, 1 postoperative anaemia). Room turnover time (patient in to patient out) was 21 min with an average operating time of 7 min. Recurrence of haemorrhoids within 1 year occurred in 50 (27,3%) patients. CONCLUSIONS: Laser haemorrhoidoplasty appears to be a promising and effective nonexcisional surgical procedure in the treatment of symptomatic haemorrhoidal disease with high patient satisfaction, acceptable postoperative symptoms, minimal complications and short operating times.

Comparison of Laser Haemorrhoidoplasty and Ferguson Haemorrhoidectomy in Treating Grade III and Grade IV Haemorrhoids: A Prospective Randomised Study.

OBJECTIVE: To compare the efficiency and safety of laser haemorrhoidoplasty (LH) with Ferguson haemorrhoidectomy (FH) in patients with third- and fourth-grade haemorrhoids. STUDY DESIGN: Randomised controlled trial. PLACE AND DURATION OF STUDY: General Surgery Clinic, Medipol University Pendik Hospital, Istanbul, Turkey, from 1st December 2021 to 1st May 2022. METHODOLOGY: The patients who had an indication for surgery for grade III or grade IV haemorrhoidal disease (HD) and who were 18 years and older were randomly allocated to the two study groups. While LH was performed using a 980-diode laser in the patients enrolled in the laser group, a standard FH was performed using diathermy in the patients in the second study group. The length of surgery (LOS), the number of excised lumps, wound healing time, time to symptom relief, pre- and postoperative Visual Analogue Scale (VAS) scores and the difference between them (Δ VAS), and complication rates were compared between two study groups. RESULTS: LH had less LOS with a similar number of excised lumps, furthermore, it provided faster-wound healing and less time-to-symptom relief when compared to FH. The median VAS score decreased from 5 to 0 in the LH group and from 5 to 2 in FH, and Δ VAS scores of the groups were statistically significantly different (p<0.001). LH also had better outcomes than FH in terms of having any type of postoperative complication. CONCLUSION: LH might be an alternative treatment modality in patients with grade III and grade IV HD with a low level of complication rate. KEY WORDS: Haemorrhoids, Laser therapy, Haemorrhoidectomy, Operative time, Pain measurement, Postoperative complications.

Efficacy and Safety of Intense Pulsed Light and Nonablative Fractional 1440-nm Diode Laser to a Combination of the 2 Modalities for Facial Rejuvenation.

BACKGROUND: The aging process involves laxity, hyperpigmentation, and telangiectasias. It is important to target those elements of aging to be successful at achieving rejuvenation. OBJECTIVE: To determine the efficacy, safety, and patient satisfaction of a combination intense pulsed light (IPL) and 1440-nm diode laser versus either treatment alone. METHODS: Forty subjects were enrolled in this randomized split-face trial: 20 were randomized to Group A (received IPL on one side of the face and IPL followed by the 1440-nm diode laser on the other side) and 20 were randomized to Group B (received 1440-nm diode laser on one side of the face and IPL followed by the 1440-nm diode laser on the other side). RESULTS: Investigators reported a percent improvement of 40% to 50% in all 3 groups at day 120; blinded investigator Global Aesthetic Improvement Scores were better in the combination group-90% compared with 84% and 83% in the IPL and 1440-nm diode laser groups, respectively. Wrinkling scores was significantly improved in the 1440-nm diode and combination groups. Hyperpigmentation and telangiectasias were significantly improved in all 3 groups. Adverse events were self-limited. CONCLUSION: Combination treatment with IPL and 1440-nm diode laser was found to be safe and effective and resulted in higher subject satisfaction.

Efficacy and safety of endovenous laser ablation with the 1470 nm diode laser using a novel optical probe.

Objectives: Outcome assessment of a novel optical fiber probe for the 1470 nm diode laser under real-world conditions. Methods: Prospective clinical pilot study in 10 patients undergoing endovenous laser ablation with a follow-up period of 1 year. Primary endpoints were efficacy and safety. Secondary endpoints include, inter alia, quality of life and patient satisfaction. Results: After a follow-up period of 1 year all treated vein segments were still occluded. Only mild and short-term side effects (hematoma, ecchymosis and hyperpigmentation) were observed. No intake of pain medication was needed and a quick return to normal activity was documented (0.9 days). Clinical hallmarks of the venous disease (VCSS) improved significantly (p= .003). All patients were very satisfied with the treatment and quality of life (AVVQ) was significantly improved after the procedure (p=.008). Conclusions: The study demonstrates that the endoluminal treatment with the novel fiber probe is highly effective and safe.

2940-nm erbium:YAG laser versus 980-nm diode laser in the treatment of multiple seborrheic keratoses: A prospective comparative randomized study.

BACKGROUND: Seborrheic keratoses (SKs) are the most common benign epithelial tumors encountered in clinical practice. Complications associated with traditional treatments of SKs urge the scientists to seek alternative treatment modalities. Objective To compare the efficacy and safety of 2940-nm erbium-doped yttrium aluminum garnet (Er:YAG) laser versus 980-nm diode laser both clinically and dermoscopically for the treatment of seborrheic keratosis. METHODS: Thirty subjects with multiple SKs were randomized to receive two sessions of either Er:YAG laser (n = 15) or diode laser (n = 15) and were followed up for 2 weeks after each session, and at 3 and 6 months after the second session. RESULTS: Both lasers exhibited significant clearance of SKs with no significant difference in clinical and dermoscopic improvement between the two systems. However, Er:YAG laser showed shorter total downtime but more serious erythema, while scarring and hyperpigmentation were observed in diode laser group. No recurrence was detected in both groups at 6 months follow-up. CONCLUSION: Er:YAG and diode lasers both are effective, non-invasive and well-tolerated techniques in treatment of SKs.

Ocular complications secondary to diode laser-assisted eyebrow epilation.

We describe two cases of ocular complications secondary to Diode laser assisted eyebrow epilation. Both included patients were women who underwent an eyebrow epilation procedure with Diode laser. A few hours after the procedure they started complaining with photophobia and blurred vision. They were diagnosed with anterior acute uveitis and treated with topical steroids and mydriatics. During the follow-up the presence of sequelae derived from the laser procedure (mydriasis and corectopia in both patients, cataract in the second one) was confirmed. Laser hair removal of the eyebrows can induce irreversible eye damage. Complete and reliable information regarding the potential side effects of this procedure and proper use of appropriate safety devices is mandatory. We point out the importance of the potential ocular side effects associated with these cosmetic devices.

Safety and efficacy for hair removal in dark skin types III and IV with a high-powered, combined wavelength (810, 940 and 1060 nm) diode laser: A single-site pilot study.

BACKGROUND: Previous studies have demonstrated the superior efficacy of a high-power diode laser (4800 W) with a wavelength of 810 nm over others with less power and the same wavelength, while also being safe and comfortable for the patient. However, the use of this laser is limited on dark skin. OBJECTIVES: This study aims to compare the efficacy, safety, and comfort of a 4800 W diode laser (810 nm) with that of the new Blend diode laser (810 nm, 940 nm, and 1064 nm). Furthermore, the study aims to demonstrate that the Blend diode laser delivers better results on darker skin. MATERIALS AND METHODS: A 810 nm diode laser was compared with the Blend diode laser (810, 940 and 1064 nm) (Primelase, Cocoon Medical). A side-by-side comparative study was carried out over three sessions involving fourteen participants with skin types III and IV, with evaluation of the results 6 months after treatment. The study was performed at the Tennessee Clinical Research Center, Nashville, Tennessee, USA. This evaluation was based on efficacy, safety, comfort, and participant satisfaction. RESULTS: Blend diode laser treatments were performed with fluences 40% (SE = 0.04%) higher than those of the 810 nm. Besides mild-to-moderate transient discomfort during the procedure, the Blend diode laser also produced an increased pricking sensation that was 1.8 points higher on a 10-point scale (p < 0.05), due to the higher fluence used. Hair reduction was 12% higher with the Blend diode laser, with a confidence level of 70%. Moreover, participants were more satisfied with the results of the Blend diode laser than with the diode laser (50% very satisfied vs. 36%, respectively). No long-term adverse effects were observed. CONCLUSIONS: The new Blend diode laser has been shown to be more effective and satisfactory than 810 nm diode laser on dark skin types III and IV, while also being safe and comfortable for participants.

A prospective multicenter randomized clinical trial comparing endovenous laser ablation, using a 1470 nm diode laser in combination with a Tulip-TipTM fiber versus radiofrequency (Closure FAST™ VNUS®), in the treatment of primary varicose veins.

BACKGROUND: The treatment of chronic venous disease, has largely shifted from high ligation and stripping to endovenous thermal ablation (EVTA) techniques, because of its comparable efficacy and lack of invasiveness. This clinical trial aimed to compare the efficacy of two thermal ablation techniques, endovenous laser ablation (EVLA) 1470-nm with Tulip-TipTM fiber and radiofrequency ablation (RFA) ClosureFastTM using a non-inferiority design for occlusion rate (primary outcome). METHODS: A prospective multicenter randomized clinical trial randomized 280 patients for the treatment of great saphenous vein (GSV) reflux. Primary outcome was the GSV occlusion rate, secondary outcome factors were the possible side-effects of the treatment such as pain, ecchymosis, quality of Life (CIVIQ-20), revised Venous Clinical Severity Score (r-VCSS). One-year follow-up period. RESULTS: The total occlusion rates at one year follow-up were 96.4% and 94.5% in the EVLA and RFA groups respectively (P=0.15). Regarding secondary outcomes, such as postoperative CIVIQ-20, r-VCSS, analgesia, absenteeism, there was no significant difference between both treatment groups. CONCLUSIONS: RFA and EVLA, using a 1470 nm laser with Tulip-TipTM fiber, of the GSV results in equal occlusion rates at one year, with comparable postoperative pain and improved quality of life.

Office hysteroscopic metroplasty with diode laser for septate uterus: a multicenter cohort study.

OBJECTIVE: To investigate the effectiveness and safety of office hysteroscopic metroplasty by diode laser for the treatment of septate uteri. STUDY DESIGN: We performed a prospective cohort study including 41 nulliparous women diagnosed with septate uterus and a history of primary infertility or recurrent miscarriage. All patients underwent hysteroscopic metroplasty for the treatment of the uterine septum, which was performed in-office setting using a 4.3 mm continuous-flow hysteroscope and a 15-watt diode laser at 1470 nm. Surgical and reproductive outcomes after 2 years of follow-up are reported. RESULTS: The procedure was well tolerated by 93% of patients. No surgical complications were reported. Thirty women out of 38 (78.9%) became pregnant: 17 (56.7%) pregnancies were spontaneously conceived, and 13 (43.3%) were obtained with assisted reproductive techniques. Twenty-four (80%) of the 30 pregnant women had a live birth, with a cumulative live birth of 63.2% among the 38 women (95% CI: 45.9-78.2%). There were no cases of post-partum hemorrhage or uterine rupture among 14 (58.3%) women who had vaginal deliveries. CONCLUSION: Office hysteroscopic metroplasty for septate uterus using diode laser appears to be a feasible and safe alternative to other available techniques and has sufficient efficacy in terms of reproductive outcomes to be considered for further investigations.
