Abstract

Objectives: To assess the efficacy of PDL in treating PWS and analyze the association between the treatment outcomes and the characteristics of the patients’ lesions. Hence, optimizing treatment regimens based on collected data. Methods: A retrospective study was conducted on 86 PWS patients treated with PDL at Hoang Tuan Clinic from May 2020 to May 2023. Results: The overall response rate of Vietnamese patients was 73.3% (63/86). The response rate was generally not associated to age, gender, and lesion location. Lesions grade 1 and 2 responded well after only 6 - 15 sessions. For lesions grade 3, increasing the number of treatment sessions beyond 15 sessions hardly increased treatment effectiveness. Lesions grade 4 required more than 16 treatments to reach acceptable results. Conclusion: 595nm PDL was effective in the treatment of PWS in Vietnamese patients. The response rate was mainly influenced by lesion grades and the number of treatments session. Grade 1 and 2 lesions can improve significantly with shorter regimens while regimens exceeding 15 treatments should be considered for patients with lesions grade 3 and 4.
