To place a collagen membrane containing crushed nasal septal cartilage over the nasal dorsum to see how this graft can improve the results of visible postsurgical irregularities in thin skinned patients.


Fifty-seven patients were treated between 2006 and 2010 (26 males and 31 females) whose ages ranged between 31 and 55 years old. They were divided into group a, defect <1 mm, group b defect between 1 and 2 mm, group c defect >3 mm. These patients presented intraoperative nasal dorsum irregularities that were corrected with 57 cartilage grafts in conjunction with collagen membrane.


All of our patients showed an initial over-correction. A dense network of collagen fiber bundles was observed running parallel to the surface of the membrane at the connective tissue–membrane interface. The clinical percentage of volume reabsorption was about 5% after 6 months, measured with clinical pictures and a clinical follow-up. No infection was noted, only 1 patient of dislocation was observed, and 5 patients required some refinements at the long-term follow-up.


In the authors’ experience the use of bilayered combined cartilage and collagen membrane grafts gives the best aesthetic results with balanced tip projection and dorsum fullness, and avoids thickness and texture modification of the skin above the graft. The use of Bio-gide membrane avoids all problems related to the donor site and shortens surgical time.
