Аннотация
BACKGROUND: Laser treatment has emerged as a novel treatment modality for onychodystrophy. Only a few small series have assessed the efficacy of laser treatment in onychodystrophy, most of which were case reports. The therapeutic effect of the 1064 nm neodymium-doped:yttrium aluminum garnet (Nd:YAG) laser for onychodystrophy has been demonstrated. Recently, the picosecond Nd:YAG (PSNY) laser has been introduced to improve various skin disorders.
AIMS: The aim of this study was to verify the efficacy of a 1064 nm PSNY in management of idiopathic onychodystrophy.
METHODS: We present a case series of dystrophic nails treated with a PSNY for onychodystrophy improvement. Planimetry using ImageJ software was used to calculate lesion reduction and proximal clear nail growth. Clinical improvement was assessed using a 5-point Global Assessment Scale (GAS). Adverse events were also assessed.
RESULTS: Twenty-five patients (11 males and 14 females) with a total of 128 nails (94 finger nails and 34 toe nails) were treated. The mean treatment number was 8.7 ± 6.2, and the mean total duration of treatment was 33.4 ± 34.6 weeks. The average proportion of the lesion area decreased significantly (from 65.9% to 46.6%) after PSNY treatment (P < .001). The mean GAS (3.16 ± 1.18) exhibited fair improvement, and there were no serious adverse events.
CONCLUSION: The 1064 nm PSNY laser can provide fair improvement for onychodystrophy with a good prognosis at least during the follow-up period and optimal cosmetic results in Asian patients.
