RESUMO
Here we demonstrate the optimization of gravure printed metal ink, dielectric, and semiconductor formulations. We present a technique for nondestructively imaging printed films using a commercially available flatbed scanner, combined with image analysis to quantify print behavior. Print speed, cliché screen density, nip pressure, the orientation of print structures, and doctor blade extension were found to have a significant impact on the quality of printed films, as characterized by the spreading of printed structures and variation in print homogeneity. Organic semiconductor prints were observed to exhibit multiple periodic modulations, which are correlated to the underlying cell structure.
RESUMO
BACKGROUND: Removal of skin cancer at or near the vermilion border may result in a partial-thickness combined cutaneous and mucosal lip defect for which repair has potential for poor cosmetic and functional outcomes. OBJECTIVE: We sought to describe the closure and results from repair of combined lip defects using 2 island pedicle or V-Y flaps, 1 for the cutaneous lip and 1 for the mucosa. METHODS: A retrospective review of all patients with combined defects of the lip who underwent double island pedicle or V-Y flap repair from June 2008 to December 2013 was performed. RESULTS: Ten patients (6 female, 4 male; ages 35-89 years, mean age 60 years) had defects on the upper lip in 8 cases and on the lower lip in 2 cases. Follow-up was for 3 months or longer with good or excellent outcomes in all cases. LIMITATIONS: This was a nonrandomized, unblinded clinical case series with a limited sample size. CONCLUSION: Double island pedicle or V-Y flap repair is an elegant closure with good to excellent results and may avoid potential problems inherent in other repair options.
