Minimal Invasive Approach for Lips Venous Lake Treatment by 980 nm Diode Laser with Emphasis on the Aesthetic Results. А Clinical Series

Experience with 808-nm diode laser in the treatment of 47 cases of oral vascular anomalies

Treatment of oral vascular anomalies (OVA) has focused on minimally invasive techniques rather than radical surgery. We investigated the efficacy and safety of diode laser using the photocoagulation technique in the management of OVA. Forty-seven subjects with OVA were treated with forced dehydration with induced photocoagulation (FDIP) using diode laser (808 nm/4.5 W). This series consisted mostly of male (63.8%) and non-white (63.8%) patients with a mean age of 57.4 years. Varices (91.5%), venous malformations (6.4%), and hemangiomas (2.1%) with a mean size of 7.1 (±4.9) mm were the conditions treated. OVA presented as a nodular lesion (63.8%) involving mainly the lower lip (46.8%). Pulsed laser mode was used as standard and the number of applications varied from one to four sessions, with the majority requiring only one (83%) FDIP session. Kaplan-Meier analysis revealed that complete clinical healing can occur on the 15th day (n=9/29.5%), followed by the 20th (n=6/45.5%), and 30th (n=7/70.5%) days. Postoperative edema was observed in 31 (66%) patients, and recurrence of the lesion occurred in two (4.2%). Based on the data on complete clinical healing, minimal patient discomfort, and satisfactory esthetic results, we can confirm that FDIP by diode laser is a promising candidate for the safe and efficacious treatment of OVA.

A Novel Air-Cooled Nd:YAG Laser for the Treatment of the Venous Lakes of the Lips

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.

Comparative Evaluation of Efficacy and Safety of the Diode Laser (980 nm) and Sclerotherapy in the Treatment of Oral Vascular Malformations

Background

Vascular malformations are structural abnormalities which are formed by progressively enlarging aberrant and ecstatic vessels without endothelial cell proliferation and composed of the type of vessel involved, i.e., capillary, veins, and arteriovenous. Treatment of vascular malformations may involve many techniques like sclerotherapy, embolization, surgical resection, cryotherapy, laser treatment, or medical therapy. This observational prospective study is aimed at evaluating and comparing the effects and efficacy of diode laser and sclerotherapy in the treatment of oral vascular malformation.

Materials and Methods

40 patients presenting with oral vascular malformation were included in the present study. The patients were divided equally (20 in each) into two groups, i.e., the laser group and sclerotherapy group. Sclerotherapy was performed with 3% sodium tetradecyl sulfate while the laser group was treated with diode laser 980 nm with transmucosal thermophotocoagulation. The patients were assessed for the response, remission, and side effects. The results obtained were tabulated and compared with the chi-square test.

Results

Side effects were found significantly lesser in the laser group compared to the sclerotherapy group (p < 0.05). Statistically significant difference was seen for postoperative pain between two groups. The laser group had mild to moderate pain compared to severe pain in the sclerotherapy group. Recurrence was observed more in the laser group compared to the sclerotherapy group.

Conclusions

Laser and sclerotherapy with 3% sodium tetradecyl sulfate both are effective in the treatment of vascular malformations. Diode laser seems to be better than sclerotherapy given lesser side effects and comfort to the patients while sclerotherapy seems to be better in respect to recurrences.

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

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.

Venous Lakes of the Lips Successfully Treated With a Sclerosing Agent 1% polidocanol: analysis of 25 report cases

•

Venous lake (VL) isa venous ectasia occurring on the lips in the elderly.

•

Treatment of lip venous lake includes surgical excision, laser therapy, infrared coagulation, and cryotherapy.

•

Sclerotherapy is an effective and acceptable option for treatment of venous lake lesions of the lips in patients.

Background

Venous lakes of the lip is vascular ectasia that generally appears on the lower lip and other sun-damaged surfaces of skin in elderly patient. There are many local therapies for treatment of lip venous lake such as surgical excision, cryotherapy, infrared coagulation and laser therapy. Sclerotherapy as treatment is used in varicose veins, leg telangiectasia, hemorrhoids and hemangiomas but for lip venous lake only two case has been reported. Therefore, we managed this study to determine the efficacy of injection of 1% polidocanol in the treatment of venous lake lesions.

Methods

This is retrospective study. Twenty five adult patient presenting with several localizations of venous lake were enrolled in the study. Informed consent was given before the treatment and a photo of the venous lake was taken. After the lesion was cleaned with an antiseptic, was slowly injected 1% polidocanol into each patient's lesion, followed by compression for 5 min. Visual Analog Scale (VAS) scale was used to indicate patient satisfaction.

Result

Lesions were completely cleared in all patients after treatment. The lesions generally disappeared in two cases leaving an insignificant scar, in two cases become angioedema with two sessions of sclerotherapy. İn other cases side effects were not observed.

Conclusion

Sclerotherapy with polidocanol is an easy, inexpensive method and is found very effective in the treatment of lip venous lake. İn the future it offers an alternative to other classic methods.

A series of 33 older patients with lip venous lake treated by sclerotherapy

BACKGROUND

Venous lake lesion is a venous ectasia that can occur on the lips of older people. Although different therapies have been used, there is no guideline for treating this lesion. The purpose of this study was to evaluate whether sclerotherapy is an effective and acceptable option for treatment of venous lake lesions of the lips in older patients.

METHODS

Medical records and images were retrieved from the archives of a geriatric dentistry clinic between 2005 and 2017. A total of 33 older patients treated with 5% ethanolamine oleate were included. Clinical information was selected and described.

RESULTS

The female gender was predominant (64%), and the patients' age ranged from 66 to 90 years. The majority of the patients were Caucasian (91%), and 82% were under treatment for hypertension. In 91% of the cases, the lesions were located on the lower lip and varied from 3 to 10 mm in diameter. A complaint period lasting longer than 2 years was reported by 58% of the patients. Color alteration was the most common type of esthetic complaint. Only one application of sclerotherapy was performed in 85% of the cases. For the remaining patients, two sessions were necessary. The total dose ranged from 0.3 to 0.9 ml. Complete regression of the lesions was observed in all cases. No complications or recurrences were reported.

CONCLUSION

Sclerotherapy with ethanolamine oleate is an effective, affordable, and predictable treatment for venous lake lesions of the lips in older patients.

Dermoscopy of venous lake on the lips: A comparative study with labial melanotic macule

BACKGROUND

Venous lake (VL) is a common vascular tumor occurring on the lips in the elderly. VL is sometimes difficult to distinguish from melanotic lesions such as labial melanotic macule (LMM) or oral malignant melanoma. However, the dermoscopic features of VL have not been sufficiently established in the literature.

OBJECTIVE

This study was aimed at investigating the dermoscopic features of VL on the lips, and to compare the dermoscopic features of VL with those of LMM.

METHODS

We retrospectively investigated the dermoscopic findings of histopathologically proven cases of VL and LMM.

RESULTS

The structureless pattern (78.6%) and globules/clods (42.9%) were the common patterns in VL cases. Purple was the most frequent color (78.6%), followed by red (42.9%) and blue (42.9%). The structureless pattern (p = 0.003) and the colors purple (p = 0.000), red (p = 0.003), and blue (p = 0.018) were significantly more common in VL than in LMM. In contrast, lines (p = 0.000) and dots (p = 0.044) as patterns, and brown (p = 0.000) and gray (p = 0.044) colors were significantly more frequent in LMM. White structures were more common in VL than in LMM (p = 0.001).

CONCLUSION

Structureless patterns or globules/clods with purple, red, or blue coloration can be useful findings when differentiating VLs from LMM on dermoscopy. Therefore, dermoscopic evaluation is a helpful noninvasive ancillary tool in the diagnosis of VL.

Diode laser to treat small oral vascular malformations: A prospective case series study

OBJECTIVE

The current work examined a consecutive series of patients presenting vascular malformations (VMs) and venous lakes (VLs) of the lip and oral mucosa who were treated with transmucosal diode laser applications and assessed over a 1 year period.

STUDY DESIGN AND METHODS

Fifty-nine patients (31 males and 28 females) presenting low-flow VMs or VLs of the oral cavity were treated transmucosally using a diode laser (with an 830 nm operating wavelength and 1.6 W output power) with a 320 µm diameter flexible fiber. All the lesions were assessed 7 days, 30 days, and 1 year after the laser treatment, and the lesion reduction percentage was scored on a one to five scale. The patients were also asked to assess their pain perception daily during the 7 days following the treatment using a visual analog scale (VAS).

RESULTS

There were no procedure-related intra- or post-operative complications; only modest pain intensity was reported. Thirty days after the treatment, lesion reduction was described as excellent or good in 52 cases; it was fair or poor in 7. Six patients (F:M ratio 2:4) required a second diode laser application. At the 1 year follow-up, volume reduction was complete in 48 out of 59 patients; there were five recurrences (F:M ratio 3:2). No relevant gender-related differences were noted.

CONCLUSION

The use of diode laser application to treat small oral VMs and VLs was associated to shorter operating times and fewer postoperative complications with respect to the scapel surgery approach. More than one session may nevertheless be required if the anomaly is larger than 10 mm. Lasers Surg. Med. 50:111-116, 2018. © 2017 Wiley Periodicals, Inc.
