INTRODUCTION: The increasing use of metal implantable devices has raised awareness of nickel allergy. Preoperative patch testing for patients with pectus excavatum (PE) with a known metal allergy or history of atopy is an accepted practice before the Nuss procedure. The Nuss bar manufacturer offers a metal disc for preoperative testing for metal sensitivities. However, the efficacy of this disc is not well understood.
OBJECTIVE: The purpose of this study was to determine the sensitivity of the metal disc in detecting nickel allergy compared with that of standard patch testing.
METHODS: Two PE patients were referred for preoperative patch testing with the metal disc to screen for metal allergy before the Nuss procedure. Based on our initial findings, 7 patients without PE scheduled for patch testing for the evaluation of chronic dermatitis were additionally tested with the metal disc if they were found to have risk factors for nickel allergy. All patch testing was performed according to set standards.
CONCLUSIONS: The metal disc may not be adequately sensitive to determine nickel allergy before the Nuss procedure. Patch testing alone with standard formulations of nickel sulfate in petrolatum may be more sensitive in diagnosing nickel allergy.
