Porous High Density Polyethylene Used In The Expansion Of The Clinical Studies Of France Auricular Reconstruction,

Objective To explore the feasibility of applying porous high-density polyethylene (Medpor) as framework to auricle reconstruction for congenital or acquired auricular defects victims unfit or reluctant to undergo autogenous costal cartilage taking.Method 61 cases suffering from congenital or acquired auricular defects underwent auricle reconstruction with Medpor framework after expanding postauricular skin. The operation was performed by two-stages. First stage: To implant expander underneath postauricular skin or soft tissue such as notrophic scar tissue for the traumatic auricle defect victims. Second stage: To remove expander and perform auricle reconstruction placing Medpor framework between the expanded skin/scar flap and the underlying fascial flap.Results 61 cases all obtained successful reconstructed auricles. During follow up of 6 months to 5.1 years ( average at 2.8 years), the reconstructed auricles in 49 cases (80.3%) resembled their unaffected or other reconstructed ones by size and position, with verisimilar shape, clear contour and distinct auricular anatomic structures, whereas 7 cases (11.5%) evaluated their reconstructed auricles ordinarily, 3 cases (4.9%) complained the operation results for uncovering of partial auricular frame or dissatisfactory auricle shape, and 2 cases (3.3%) afraid of emergence of...
