Porous high-density polyethylene in facial reconstruction and revision rhinoplasty: a prospective cohort study

This study was a prospective cohort study. Surgical techniques included using Medpor？ in reconstruction of lamina papiracea (LP) (15 patients), frontal bone (15 patients), orbital rim (18 patients) and open rhinoplasty (8 patients). All interventions on LP were performed by endoscopic procedures. All frontal operations were carried out by bicoronal incision. In orbital defects, we used subciliary incision.From all 56 patients, 1 case had primitive neuroectodermal tumor (PNET) of maxillary sinus. In that case, reconstruction of inferior orbital rim was not successful and extrusion was occurred after radiotherapy. In rhinoplasty and other experiences no extrusion or infection were detected within the next 1 to 3？years of follow up. There were not any palpable and visible irregularities under the skin in our experiences.In this study the patients did not experience any complications during the follow up periods and the satisfaction was remarkable. Gathering these data gives rise to future review studies which can provide more organized evidences for replacing classic reconstructive methods by the presented material.Loss of tissue caused by trauma, cancer or surgery usually needs some materials for reconstruction. Initial methods which used human tissues as reconstructive materials caused different problems including disable to shape the graft, limitation of accessibility and donor site morbidity [1-3].In 1828, using artificial materials was established by using gold in nose reconstruction [1,4].Using silicon rubber, polyamide and Gore-Tex has been improved since 1950, but each of them was accompanied by different reactions such as extrusion, infection and not well-shaped slippery reconstruction [4-9].In 1970s porous high-density polyethylene (PHDPE, Medpor？) was introduced by its exclusive advantageous including no donor site morbidity, easily shaped and the minimal foreign body reaction [10-13]. Furthermore the likelihood of infection was reduced by significant vascul
