Extrusion of High-density Porous Polyethylene Implants in the Nose.

Few alloplastic implant materials have been successfully used in nasal reconstruction. The high-density porous polyethylene (HDPE) implant is the most widely accepted alloplastic material for reconstructing the nasal structure. Some authors suggest that the problems associated with using grafts and biocompatible materials are often due to errors on the part of the surgeon or the technique used. This study aims to report several cases of complications related to using HDPEs in the nose. A total of 23 patients who reacted negatively to alloplastic implants were treated. The removal of HDPE is complex due to the formation of connective tissue within it. These complications can cause permanent atrophic changes to the skin of the nose. Most of the patients presented with extrusion of their HDPE implants in the nasal columella region. All patients underwent implant removal, cleaning, disinfection, and secondary rhinoplasty. Surgeons must be able to recognize these possible complications and manage them successfully. Even today, many professionals use alloplastic grafts for reconstruction and esthetics of the nasal region. The potential for permanent damage to the skin and soft tissues, as well as complications such as infection and extrusion of the implant, makes the use of autogenous tissue preferable over alloplastic implants. Early detection and immediate treatment of complications are essential to minimize the severity of the deformity.
