| 摘要 |
A packaged kit for performing a photodynamic laser myringotomy includes a plurality of ear needles having different shaped absorbent applicators on distal ends of the needles, a vial of a single dose of an otologic formulation of mitomycin-C, a diluent carrier containing sterilized water, and a syringe. The component parts of the kit are used together to reconstitute the contents of the vial with the water in the diluent carrier, and then draw the reconstituted drug into the syringe. A selected one of the plurality of ear needles is then communicated with the syringe. The syringe and needle are then used to inject the reconstituted drug into the absorbent pad at the end of the needle, and the absorbent pad containing the drug is used to apply the drug to the tympanic membrane. The application of the drug to the tympanic membrane prepares the membrane for a myringotomy procedure, and in particular, a photodynamic laser myringotomy. |

1. A method comprising:
using an apparatus for application of a pharmaceutical to a tympanic membrane of an ear for a photodynamic laser myringotomy, the apparatus comprising a container, a syringe, at least one ear needle, at least one absorbent pad, and a packaging container, the container containing the pharmaceutical, the pharmaceutical being a single dose of an otologic formulation of mitomycin-C, the mitomycin-C contained in the container having a specific color, the at least one ear needle having a tubular length with opposite proximal and distal ends, the proximal end of the at least one ear needle being adapted for communication with the syringe, the at least one ear needle being adapted and configured such that the mitomycin-C can travel through the at least one ear needle from the proximal end of the at least one ear needle to the distal end of the at least one ear needle, the at least one absorbent pad being adapted for communication with a distal end of an ear needle, the packaging container containing the container, the syringe, the at least one ear needle, and the at least one absorbent pad as a packaged kit; applying the mitomycin-C to tissue; and using a laser beam having a wavelength that is specifically tuned to the specific color of the mitomycin-C to ablate the tissue. |
