Polyethylene implants in nasal septal restoration.
IMPORTANCE Numerous techniques have been described to repair nasal septal perforations (SPs). However, many are technically challenging, with varying degrees of success. OBJECTIVE To evaluate the use of polyethylene (Medpor; Porex Technologies) implants in the closure of nasal SPs. DESIGN AND SETTING Prospective cohort study in an academic research setting. PARTICIPANTS Fourteen patients ...
متن کاملMetal Powder-filled Polyethylene Composites. v. Thermal Properties Metal Powder-filled Polyethylene Composites. v. Thermal Properties
Thermal properties—such as thermal conductivity, thermal diffusivity, and specific heat—of metal (copper, zinc, iron, and bronze) powder-filled high-density polyethylene composites are investigated experimentally in the range of filler content 0–24% by volume. Experimental results show a region of low particle content, 0–16% by volume, where the particles are distributed homogeneously in the po...
متن کاملUse of Porous Polyethylene Implants in Nasal Reconstruction
Complex augmentation rhinoplasty to correct both functional and cosmetic deformities remains a challenge for the rhinoplasty surgeon. The skeletal structure maybe severely deformed from previous trauma or underlying disease processes. These resulting deformities may occur together with significant soft tissue disfigurement. Correction of all these aspects requires careful selection of graft mat...
متن کاملThe use of high-density polyethylene implants in facial deformities.
OBJECTIVE To determine the usefulness of porous high-density polyethylene implants (Medpor) in a variety of facial skeletal deformities and subcutaneous defects, excluding those associated with acute maxillofacial trauma. DESIGN Case series. SETTING Academic tertiary care referral center in Baltimore, Md. PATIENTS Thirty-four patients (age range, 20-74 years) with facial deformities requi...
متن کاملTribo-biological deposits on the articulating surfaces of metal-on-polyethylene total hip implants retrieved from patients
Artificial total hip arthroplasty (THA) is one of the most effective orthopaedic surgeries that has been used for decades. However, wear of the articulating surfaces is one of the key failure causes limiting the lifetime of total hip implant. In this paper, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) were employed to e...
