Is Q-Switched Neodymium-Doped Yttrium Aluminium Garnet Laser an Effective Approach to Treat Xanthelasma Palpebrarum? Results from a Clinical Study of 76 Cases

Interventional and device treatment of the periocular area

Growth in the research, innovation, and development of laser and energy-based technologies over the past few decades has led to dramatic increases in treatment options for dermatologic and cosmetic concerns of the periorbital area. We highlight recent treatment options using laser and energy-based devices for the clearance of periocular pigmented lesions, including solar lentigines and nevus of Ota; vascular lesions, including port-wine birthmarks, infantile hemangiomas, superficial telangiectasias, and reticular veins; laser ablation of benign tumors, such as xanthelasma; cosmetic rejuvenation; treatment of infraorbital dark circles and festoons; laser removal of eyebrow and eyeliner tattoos; and device-based treatment of chronic dry eyes.

A Practical Review of the Management of Xanthelasma palpebrarum

Xanthelasma palpebrarum is the most common type of xanthomatous lesion. Various methods for treating Xanthelasma palpebrarum have been reported. We conducted a systematic review to evaluate the efficacy and associated complications of different treatment methods, and we summarized these findings as a practical review designed to be clinically useful, accessible, and impactful.

Methods

The PubMed and Embase databases were searched to identify clinical studies that reported on outcomes and complications of different methods of Xanthelasma treatment. The electronic databases were searched from January 1990 to October 2022. Data on study characteristics, lesion clearance, complications, and recurrences were collected.

Results

Forty-nine articles (including 1329 patients) were reviewed. The studies reported on surgical excision, laser modalities, electrosurgical techniques, chemical peeling, cryotherapy, and intralesional injection. The majority of studies were retrospective (69%) and single-arm (84%). Surgical excision combined with blepharoplasty and skin grafts showed excellent outcomes for large Xanthelasma. CO₂ and erbium yttrium aluminum garnet (Er:YAG) were the most commonly studied lasers and showed more than 75% improvement in over 90% and 80% of patients, respectively. Comparative studies reported better efficacy for CO₂ laser than both Er:YAG laser and 30%-50% trichloroacetic acid. Dyspigmentation was the most encountered complication.

Conclusions

Different methods for the treatment of Xanthelasma palpebrarum have been reported in the literature, with moderate to excellent efficacy and safety profiles depending on the size and location of the lesion. Surgery is more appropriate for larger and deeper lesions, whereas laser and electrosurgical techniques can be used in smaller and more superficial contexts. Only a limited number of comparative studies have been conducted, and novel clinical trials are necessary to further augment appropriate treatment selection.

Clinical efficacy of 1,444nm Nd:YAG laser for xanthelasma palpebrarum

Xanthelasma palpebrarum (XP) does not regress spontaneously and most patients complain of cosmetic discomfort. This study presents the results of treatment of XP using 1,444 nm Nd:YAG laser. We aim to evaluate the clinical efficacy of a 1,444 nm Nd:YAG laser in XP. Twenty-eight patients with XP treated with 1,444 nm Nd:YAG laser were analyzed retrospectively. A physician scored the results based on the reduction of the initial lesion area under six categories. The results were scored as follows: no effect (0% clearing of xanthelasma area), some response (1-24% clearing), moderate response (25-49% clearing), marked response (50-74% clearing), satisfactory result (75-99% clearing), and excellent result (100% clearing). Twelve patients (42.8%) showed excellent clearance and 10 patients (35.7%) had clearance greater than 75%. Overall, 24 patients (85.7%) showed improvement higher than 50%. Half of the patients (14 patients) ended the treatment with satisfactory results with one treatment session. Including seven patients who ended the treatment after two laser sessions, 21 patients (75%) reported satisfactory results and ended the treatment after 1 to 2 laser sessions. XP treatment with 1,444 nm Nd:YAG laser showed promising results. We believe it can be an effective and safe treatment modality for XP.

Xanthelasma Palpebrarum: More than Meets the Eye

Xanthelasma palpebrarum (XP) is the most common form of cutaneous xanthomata, and is important aesthetically, because of its close relation to the eyes, as well as medically for its association with cardiovascular disease (CVD). To provide avant-garde review discussing the various aspects of XP, including its aetio-pathogenesis and various treatment modalities. A structured Pubmed and Medline were searched for relevant articles. The finding of recent research has strongly espoused the link between XP and CVD, and mechanisms have been suggested for its formation. The new technologies have led to a multitude of treatment options for XP. XP is a multi-faceted entity; other than simple treatment of the cosmetic aspect of the disease, one must be cognizant of its cardiovascular implications.

Treatment of Xanthelasma Palpebrarum using Pulsed Dye Laser: Original Report on 14 Cases

Xanthelasma palpebrarum, a benign xanthoma occurring around the eyes, are treated using lasers like carbon dioxide, argon, pulsed dye, YAG, and diode(1450) laser .Several studies on PDL for xanthelasma palpebrarum (XP) have been reported from abroad but as per our knowledge there are no Indian studies in this regard. We report the efficacy of pulsed dye laser in the management of xanthelasma palpebrarum in Indian patients.

Xanthelasma: An Update on Treatment Modalities

Xanthelasmas are localized accumulation of lipid deposits on the eyelids. Lesions are typically asymptomatic and treatment is often sought for cosmetic purposes. Unfortunately, there is paucity of strong evidence in the literature for the effective treatment of normolipidemic xanthelasmas. A literature search using the term “xanthelasma” was carried out in PubMed and Medline databases. Only articles related to treatment were considered and analyzed for their data. Commonly cited treatments include topical trichloroacetic acid, liquid nitrogen cryotherapy, and various lasers including carbon dioxide, Er:YAG, Q-switched Nd:YAG, and pulse dye laser. However, traditional surgical excision has also been used. This article reviews these currently accepted modalities of treatment.

Xanthelasma palpebrarum - a brief review

Xanthelasma palpebrarum is the most common cutaneous xanthoma, characterized by yellowish plaques over eyelids – most commonly, over the inner canthus of the upper lid. It is triggered by hyperlipidemia, thyroid dysfunction, and diabetes mellitus. Xanthelasma results from perivascular infiltration of mono- and multinucleated foam cells within lipid-laden cytoplasmic vacuoles in the superficial reticular dermis. Different modalities of treatment, such as simple surgical excision, cryotherapy, chemical peeling with trichloroacetic acid, radiofrequency, and laser, are used in the treatment of xanthelasma palpebrarum. A brief review of current treatment strategies is presented here.

Treatment of xanthelasma palpebrarum with a 1064-nm, Q-switched Nd:YAG laser

BACKGROUND

Xanthelasma palpebrarum is the most common cutaneous xanthoma characterized by soft, yellow papules or plaques that arise on the periorbital skin. As these lesions can be cosmetically disfiguring, many patients seek medical help to remove these lesions.

OBJECTIVE

To determine the effectiveness and minimum number of treatment sessions with a 1064-nm, Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser for the treatment of xanthelasma.

METHODS

A retrospective review of patients with xanthelasma consecutively treated with Q-switched Nd:YAG laser was conducted. Forty-six patients with 103 lesions were identified from January 2012 through August 2015. Photographs taken of patients immediately before treatment and 4-8 weeks after treatment were independently evaluated by 2 dermatologists.

RESULTS

After a single treatment session, 93.2% of lesions had some degree of clearance. All lesions had excellent-to-complete clearance after at least 4 treatment sessions. Patients usually required 4 treatment sessions for optimal results.

LIMITATIONS

This was a retrospective study. Treatment parameters varied, follow-up periods were not uniform, and response was not assessed with a validated scale.

CONCLUSION

The Q-switched Nd:YAG laser is effective and well tolerated in the treatment of xanthelasma in our study population.

Erbium:yttrium aluminum garnet laser versus Q-switched neodymium:yttrium aluminum garnet laser for the treatment of xanthelasma palpebrarum

BACKGROUND

Several lasers have been used for the treatment of xanthelasma palpebrarum (XP), such as Q-switched neodymium:yttrium aluminum garnet (QSNd:YAG) and erbium:yttrium aluminum garnet (Er:YAG) laser. Up to now, a comparative study among these laser options in the treatment of XP has not been reported.

OBJECTIVE

The aim of this study was to compare the clinical efficacy and response rates of QSNd:YAG and Er:YAG in the treatment of XP.

METHODS

Sixty patients with a total of 102 XP lesions were randomly and equally divided into two groups. The first group was treated with QSNd:YAG at a fluence of 10 joule/cm², 10 Hz and 2 mm spot size, and the second group was treated with Er:YAG at 200-300 millijoule, 4 Hz and 2 mm spot size.

RESULTS

In the Er:YAG group, the percentage of patients who required 3 or 4 sessions and wound healing time were higher compared to those of the QSNd:YAG group. Furthermore, the percentage of patients who had an improvement score of 4 was higher in the Er:YAG than that in the QSNd:YAG group.

CONCLUSION

Er:YAG is an efficient, successful and minimally invasive method without long-lasting adverse effects.

Continuous Wave Potassium Titanyl Phosphate Laser Treatment is Safe and Effective for Xanthelasma Palpebrarum

BACKGROUND

Although not an accepted standard treatment, the 532-nm continuous wave potassium titanyl phosphate (CW-KTP) laser might be a powerful device to treat xanthelasma palpebrarum (XP).

OBJECTIVE

To determine the safety and efficacy of CW-KTP laser treatment for XP.

MATERIALS AND METHODS

Between January 2013 and January 2015, 30 consecutive patients with XP were treated with a 532-nm CW-KTP laser (spot size: 0.9 mm, power: 5.0 W, fluence: 36-38 J/cm, pulse width: 46 milliseconds, frequency: 2.0 Hz, passes per session: 3). In a retrospective study design, safety and efficacy data were collected and analyzed.

RESULTS

Overall, 29/30 (97%) of patients had an excellent cosmetical result. Downtime was 1 week with crusted lesions. Although slight hypopigmentation was common, only 1/30 (3%) patients had hypopigmentation that was more than expected. Recurrences (13/30; 43%) were frequent, so that yearly maintenance therapy was warranted. No major side effects were noticed.

CONCLUSION

Continuous wave KTP laser therapy is safe and highly effective for XP, although regular follow-up treatments are often necessary to maintain the achieved cosmetic results.

Comparative Study to Evaluate the Efficacy of Radiofrequency Ablation versus Trichloroacetic Acid in the Treatment of Xanthelasma Palpebrarum

Background:

Xanthelasma palpebrarum (XP) is a metabolic disorder involving the eyelids. Radiofrequency(RF) surgery and trichloroacetic acid (TCA) applications have been listed among the procedures for XP, but comparative studies are not available.

Aim:

To compare the efficacy of radiofrequency surgery versus trichloroacetic acid application in the treatment of XP.

Settings and Design:

20 consecutive cases of XP attending dermatology, medicine and endocrinology out-patient departments of M.S. Ramaiah teaching hospital were enrolled for the study. It was an open-label clinical trial conducted in our hospital for a duration of 1 year.

Materials and Methods:

20 consecutive patients conforming to inclusion criteria were selected for the study. For each patient, lesions were treated with radiofrequency ablation on one side and TCA application on the other side.

Results:

RF ablation was done for 12 patients over right eye lesions and 8 patients over the left eye lesions. TCA applications were done for 8 patients over right eye lesions and 12 patients over left eye lesions. 70% of lesions treated with RF ablation had a score of improvement of 4 and 70% of lesions treated with TCA application had a score of improvement of 4, at 4 weeks of follow-up. At four weeks of follow-up 40% in RF group and 15% in TCA group had scarring and 45% in RF group and 30% in TCA group had pigmentation.

Conclusion:

RF ablation as compared to TCA application, required fewer sessions for achieving more than 75% clearance of lesions. However, TCA applications were associated with fewer complications comparatively.

Outcomes of surgical management of xanthelasma palpebrarum

Background

Xanthelasma palpebrarum (XP) is a benign disorder manifesting as yellowish cholesterol-laden plaques on the eyelids. This paper presents the outcomes in patients with XP who have undergone surgical excision as the main modality of treatment.

Methods

A retrospective review of patients who received surgery for xanthelasma palpebrarum from March 2007 to March 2011 was conducted. Patients were classified into four grades according to the location and extent of the lesion, with grade I being the mildest and grade IV being the most diffuse. Simple excision was performed in grade I and II lesions, while local flaps and skin grafts were performed in the more advanced grades.

Results

Ninety-five cases from March 2007 to March 2011 were included in this study. 66 cases (70%), were treated by simple excision. Twenty-four cases (25%) and 5 cases (5%) were treated by simple excision in combination with or without local flaps and skin grafts. In approximately 1/4 of the patients, orbicularis oris muscle involvement was observed. 4 patients (4.2%) developed scar contracture postoperatively, which required a secondary procedure. Recurrence was reported in 3 patients (3.1%). Otherwise. There were no other reports of major complications or disfigurement.

Conclusions

We found that for lesions involving the deep dermis and/or muscle, surgical excision was the most appropriate therapeutic option.

Xanthelasma palpebrarum treatment with a 1,450-nm-diode laser

BACKGROUND

Various treatments of xanthelasma palpebrarum have been studied, including surgical excision, treatment with chemicals, and ablative laser therapy, but these methods have some disadvantages. Recently, nonablative laser therapy has been proposed as a treatment for xanthelasma palpebrarum.

OBJECTIVE

To investigate the efficacy and safety of a 1,450-nm-diode laser in the treatment of xanthelasma.

MATERIALS AND METHODS

Sixteen patients were treated using a 1,450-nm-diode laser. Fluences of 12 J/cm(2) , a 6-mm spot size, and a dynamic cooling device setting of 20 to 30 ms were used. One to four treatments 4 to 6 weeks apart were given to each patient. Photographs were taken before each treatment session and 4 to 6 weeks after the last treatment.

RESULTS

Two (12.5%), eight (50%), and four (25%) of the 16 patients were scored as having some (20-40% clearing), moderate (40-60% clearing), and marked (60-80% clearing) improvement, respectively. Focal mild transient hyperpigmentation was noted in five patients. Post-treatment local swelling lasted 3 to 4 days.

CONCLUSION

The 1,450-nm-diode laser treatment is a new, valuable treatment option for xanthelasma palpebrarum, offering relatively mild side effects. Studies including long term follow up and a comparison with alternative treatment modalities are necessary to further assess the clinical utility of this treatment. The authors have indicated no significant interest with commercial supporters.
