Abstract
Objective: To evaluate the therapeutic effect of a novel air-cooled Nd:YAG laser in the venous lakes of the lips (VLL). Background: The thermal injury is one of the most important issues during laser therapy for venous lakes. Methods: Six pieces of fresh pork livers were used to provide 30 regions with a diameter of 6 mm for experiment in vitro, among which 15 regions were treated by Nd:YAG laser with air cooling until the tissue turned gray-white, whereas the rest were treated without air cooling as control. The operation time of laser irradiation, the degree of temperature increase, and the depth of coagulation tissue were compared between two groups. Then, 60 VLL patients were selected for Nd:YAG laser treatment with or without air cooling. The operation time of laser irradiation, the degree of temperature increase, the postoperative pain visual analog scale (VAS) score, and the percentage of lesions removed within 1 month were compared. Results: In tissue studies, the treated group showed a longer operation time of laser irradiation (p < 0.01), a lower degree of temperature increase (p < 0.01), and there was no significant statistical difference in the depth of coagulation tissue (p = 0.624). In clinical studies, the treated group showed a longer operation time of laser irradiation (p < 0.01), a lower degree of temperature increase (p < 0.01), and a lower VAS score on the 1st and 2nd day, compared with the control group (p < 0.01). Conclusions: Air cooling during Nd:YAG laser for the treatment of VLL can prolong the surgical time, but lowered tissue temperature and reduced patient pain within 2 days under the premise of ensuring the treatment effect.

Abstract
Venous lakes (VLs) are fairly common vascular lesions caused by dilatation of the localized vessels on sun-damaged skin. They are usually asymptomatic; however treatment is opted to improve psychological distress caused by cosmetic disfigurement and occasionally to prevent bleeding. Multiple treatment modalities such as cryosurgery, carbon dioxide laser, pulse dye laser, sclerotherapy, and electrocoagulation have been mentioned in literatures with varying degrees of success and specific complications. Hereby, we present a case of a 40-year-old female with VL on upper eyelid treated successfully with surgical excision with better cosmesis.

Abstract
Small vascular anomalies are commonly present on the lips and other areas of the oral mucosa. These lesions are also known as venous lake lesions, and they can be treated in many ways with surgical and non-surgical methods. Laser is an arising technique for this type of procedure and its use has been growing in dental practices in the last years. The technique that uses the diode laser delivers the energy in a non-contact treatment, leading to the coagulation of the lesion in a minimally invasive manner, and for this reason, there is less chance of developing scar formation. In this report, a 56-year-old female patient had a vascular lesion on her lower lip measuring about 3.0 mm in diameter. The patient reported having it for more than 10 years. A first approach using a high-power diode laser had already been done but with no success. At this time, the diode laser was used under local anesthesia, with a flexible quartz fiber held 2 to 3 mm from the lesion, using the continuous wave mode set, 1.0 W of power for 10 seconds, with an interval of 30 seconds to prevent heat damage to the adjacent tissue. The laser was applied until the lesion appeared white and with evidence of shrinkage. In this case, two rounds of irradiation were done. After a 30-day follow-up, the lesion was repaired with no signs of scars on the lip. The diode laser is an effective technique for treating this type of lesion, with many advantages, such as providing coagulation, excellent healing, no postoperative complication, and no need for suturing. Besides all, it is also a low-cost procedure, small lesions usually require only one appointment, and this treatment is also better accepted by the patients.

Application of Fractal Dimension and Texture Analysis to Evaluate the Effectiveness of Treatment of a Venous Lake in the Oral Mucosa Using a 980 nm Diode Laser-A Preliminary Study. MATERIALS 2021; 14:ma14154140.

Abstract
Venous lake (VL) is a common lesion resulting from the enlargement of thin-walled veins surrounded by a thick wall of fibrous tissue. Photocoagulation is becoming one of the basic methods for treating small vascular lesions. The aim of this study was an application of texture analysis (TA) and fractal dimension analysis (FDA) to evaluate VL treatment. Twenty-three VLs were included in the study. We used a 980 nm diode laser, 6 W, 100 ms pulse mode with a 50% duty cycle. The total dose of energy was in a range from 80 J to 600 J. We used the difference of intensity algorithm for FDA and microcontrast and a co-occurrence matrix for TA. A complete therapeutic effect was achieved in 83%, and in 9%, scar formation was observed after three months. No healing was observed in 4%, and there was partial healing in 4%. No differences in FD were observed between the lesions after three months and the healthy mucosa. The fractal dimension and microcontrast of a vascular lesion are mutually coupled. FDA and TA is a useful and objective method of assessing treatment effects for venous lakes. The non-contact mode of the 980 nm diode laser is an effective and safe method for treating a VL.
