Intralesional triamcinolone acetonide using the Port-O-Jet and needle injections in localized dermatoses

The treatment of certain localized dermatoses with triamcinolone acetonide by needle infiltration showed a success rate of approximately 75% in a group of 1046 patients, who were followed up 6 years after a single intralesional injection. More recetitly the Port‐0‐Jet† apparatus has been used on the same range of conditions. After a good therapeutic effect had been obtained in thirty out of thirty‐nine cases in a trial series, a comparison of twenty‐nine dermatoses and three onychopathic cases revealed equally good results with both methods. The main advantages of the Port‐0‐Jet are its speed of action together with a pronounced decrease in pain compared to conventional needle injections.
