Intradermal triamcinolone treatment of nail dystrophies



With a needleless injector (Port-O-Jet), triamcinolone acetonide can readily be injected into the area of the finger-nail matrix, through the posterior nail fold. 100 cases of various nail dystrophies have been treated in this way.

Dystrophies involving the nail matrix have been found to resolve substantially in the majority of cases. Onycholysis was found to improve occasionally, but generally relapsed rapidly. However, when onycholysis was associated with matrix abnormalities more consistent and prolonged remissions of the onycholytic areas occurred.
