Vertical Bonegraft Wrap-A Technique to Increase Soft Tissue Volume in Paranasal Region.

Abstract

This study presents a technique to gain soft tissue volume in the paranasal region, using a xenogenous bonegraft wrap with a porcine pericardium collagen membrane in a patient with severe paranasal deficiency and midfacial hypoplasia. The technique consisted of using particulate bonegraft that is wrapped on collagen membrane and placed vertically and parallel to the lateral wall of the nasal cavity, over maxillary osteotomies. In a tomographic analysis of linear and volumetric measurements with 14 days and 6 months after the procedure, it was observed good stability of the vertical bonegraft wrap, as well as volume gain in the paranasal region and low absorption rate of the grafted material. This technique presented a satisfactory clinical result, promoting an improvement in facial harmony with gain volume in the paranasal region, guaranteeing greater predictability in the treatment of a patient with significant maxillary advancement surgery.
