Long-pulsed NdYAG for early bruise resolution: a case series.

Abstract

Background: Ecchymoses occur due to various insults to the skin which generally heals spontaneously within 2-3 weeks, with restoration of normal skin color. However, the prominent skin discolouration is troublesome for patients, prompting them to seek remedies for quick resolution. We highlight the importance of using long pulsed NdYAG laser as a treatment modality to speed the resolution of ecchymoses from 14 days to 24-48 hr in skin-type V-VI with negligible side effects, as its potential use is not widely known. We report on the first successful case series using this laser in skin-type V-VI.

Objectives: To assess the efficacy of long-pulsed NdYAG laser in early resolution of ecchymoses.

Methods: Six adults with skin types IV-VI with at least one ecchymosis were enrolled in the study. Subjects received treatment with the vascular mode 1064 nm long-pulsed NdYAG laser; (ALMA-Q multifunctional Q-switched ALMA laser). The number of treatment sessions varied from one to two at 3-day intervals. Photographs were taken pre-treatment, at 72 h, and 5 days post-treatment.

Results: In all six subjects, accelerated resolution of the treated bruise was evident. Treated lesions showed an average improvement of 80% after 72 h of treatment. After one week of treatment, all treated bruises completely disappeared (100%). No adverse effects were noted in any of the patients with no pain during the treatment sessions.

Limitations: Small sample size.

Conclusion: Our findings show this laser is safe and effective for rapidly resolving ecchymoses, reducing patient downtime without experiencing color changes when treated promptly.
