Laser Therapy for Vascular Malformations of the Oral Cavity: A Systematic Review.

Objectives: to compare the clinical effectiveness, safety, and aesthetic outcomes of different laser systems used for the treatment of oral vascular malformations. Materials and Methods: This review followed JBI guidelines and adhered to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020 statement. The research was performed through the databases PubMed, Scopus, and Web of Science using MeSH (Medical Subject Headings) terms for MEDLINE (PubMed), while equivalent free-text terms were applied to Scopus and Web of Science. The initial database search was performed on 20 May 2024. Studies published from 2014 to 2024 focusing on laser therapy for oral vascular lesions were included. Data quality was assessed using NHLBI and ROBINS-I V2 tools. Results: Of the 139 articles identified, 11 met inclusion criteria, assessing Nd:YAG, diode, Er,Cr:YSGG, and CO₂ lasers. The Nd:YAG laser was effective for deep vascular lesions with strong thermal effects. The diode laser provided excellent coagulation and minimal postoperative discomfort. The Er,Cr:YSGG laser offered faster healing and better cosmetic results. The CO₂ laser showed effective results with low recurrence rates. Most studies reported reduced bleeding, pain, and recovery time following laser treatment. Conclusions: Laser therapy, particularly Nd:YAG, diode, and CO₂ lasers, offers a safe, effective alternative for oral vascular malformations, providing improved outcomes and fewer complications. Future studies should include larger sample sizes and comparisons with traditional therapies.
