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.

Therapeutic effect of high-frequency ultrasound-assisted dye laser on hemangioma and its influence on serum HIF-1α in patients

Background

To analyze the therapeutic effect of high‐frequency ultrasound (HFU)‐assisted dye laser on hemangioma patients and changes in serum hypoxia‐inducible factor‐1α (HIF‐1α).

Methods

A total of 20 patients diagnosed with hemangioma in our hospital from January 2013 to March 2018 were selected, including 12 males and eight females. All patients were treated with HFU‐assisted dye laser. The site and type of hemangioma and age distribution of patients were collected, and changes in data and area of hemangioma and serum HIF‐1α before and after treatment were analyzed.

Results

The vascular condition of hemangioma in all patients was significantly improved at 7, 14, and 30 days after treatment. Gray‐scale ultrasound displayed that the tumor area was reduced by more than 50%. After treatment, the serum HIF‐1α level declined obviously after treatment compared with that before treatment, showing a statistically significant difference (P < 0.05).

Conclusion

HFU‐assisted dye laser can effectively reduce the tumor area, decrease the serum HIF‐1α level, and improve the prognosis in the treatment of hemangioma.
