“…3 Several methods were introduced to augment the depressed paranasal area including modification of Le Fort I osteotomy and insertion of autogenous bone graft and alloplastic materials. [3][4][5][6][7] Although augmentation using autogenous bone graft has been widely used, harvesting autogenous bone involves donor site morbidity, and grafted bone resorption leads to unpredictable result. Therefore, various alloplastic materials were developed and introduced with new techniques, 8 among which porous high-density polyethylene implants, Medpor (Porex Surgical Inc., Newnan, GA), have been used successfully in the augmentation of the facial skeleton.…”

The aim of this study was to determine the effect of porous polyethylene in paranasal augmentation on the overlying soft tissue. Thirty-three patients underwent paranasal augmentation using 3-mm-thick porous polyethylene and mandibular setback, and 35 patients underwent mandibular setback only. Lateral cephalograms were taken before and 6 months after the surgery to compare the soft-tissue changes in the paranasal area. Complications and patient satisfaction following the surgery were also analyzed. The average soft-tissue change in the paranasal area after the augmentation was 2.42 ± 0.33 mm, while there was no definite soft-tissue change in the paranasal area after mandibular setback alone. The ratio of soft-tissue changes to paranasal implant thickness was 80.7%. All patients in the augmentation group were satisfied with their surgical outcomes, which led to convex lateral profile with increase in midface volume. There were no complications such as postoperative infection or foreign body reaction requiring removal of implants. Paranasal augmentation using porous polyethylene is a predictable method providing minimal morbidity in patients with paranasal deficiency.

“…Usually, the surgical technique of paranasal augmentation with the use of Medpor is combined with BSSRO in the skeletal class III profile. It would be a good option for the patient who wants to avoid invasive surgery and improve cosmetic problems 1,3,5) . Medpor, the porous high-density polyethylene, has been proven stable for skeletal reconstructions.…”
