Nasal Soft Tissue Triangle Large Composite Graft Take with Postoperative Hyperbaric Oxygen Therapy: A Case Report.

Background:Auricular composite grafts hold great potential for reconstructing the nasal soft tissue triangle with desired aesthetic results because there is ample tissue available for sufficient nasal ala projection and the natural curvature of the helical rim matches that of the alar rim. The use of auricular composite grafts also results in positive functional outcomes because of the cartilaginous airway support provided to widen the external nasal valve. Composite graft survival is highly dependent on graft size, as larger sized grafts have a higher metabolic demand.To improve graft viability and reliability, hyperbaric oxygen therapy can be employed to accommodate the increased metabolic demand seen with larger composite grafts.Conclusions:This report presents the survival of a large skin and cartilage composite graft for nasal soft tissue triangle reconstruction in conjunction with hyperbaric oxygen therapy to improve graft viability.
