Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Pulsed Dye Laser
Subjects with multiple nose telangiectasias will be enrolled. One nose telangiectasia (of 5) will be treated with pulsed dye laser.
Pulsed Dye Laser
Pulsed dye laser treatments will be performed with a 595 nanometer wavelength, 20 millisecond pulse duration, at 10 Joules/cm2, with a 10 millimeter spot size.
Long Pulsed Alexandrite Laser
Subjects with multiple nose telangiectasias will be enrolled. One nose telangiectasia (of 5) will be treated with long pulsed alexandrite laser.
Long Pulsed Alexandrite Laser
Alexandrite laser will be used with a 755 nanometer wavelength, 40 millisecond pulse duration, at 88Joules/cm2, with a 6 millimeter spot size.
Pulsed Dye Laser Plus Nd:YAG Laser
Subjects with multiple nose telangiectasias will be enrolled. One nose telangiectasia (of 5) will be treated with pulsed dye laser plus Nd:YAG laser.
Pulsed Dye Laser Plus Nd:YAG Laser
The Cynergy with MultiPlex will be used with a multiplex mode system with a pulse dye laser at 585 nanometer wavelength, 20 milliseconds pulse duration, at 7 Joules/cm2 with a 7 millimeter spot size, with a short delay, followed by a Nd:YAG 1064 nanometer wavelength, 20 millisecond pulse duration, at 50 Joules/cm2 with a 7 millimeter spot size.
Electrodesiccation
Subjects with multiple nose telangiectasias will be enrolled. One nose telangiectasia (of 5) will be treated with electrodesiccation.
Electrodesiccation
A curette is used to scrape off the cancer down to the dermis. The scraping is then paused while an electrosurgical device like a hyfrecator is used next. Electrodesiccation is performed over the raw surgical ulcer to denature a layer of the dermis and the curette is used again over the surgical ulcer to remove denatured dermis down to living tissue.
No Treatment
Subjects with multiple nose telangiectasias will be enrolled. One nose telangiectasia (of 5) will receive no treatment.
