Use of diced cartilage grafts wrapped with amniotic membrane in soft tissue augmentation: experimental study
1Department of Otorhinolaryngology, Kocaeli University Medical Faculty, Kocaeli, Turkey.
Objectives:
Correcting nasal dorsal deformities and irregularities often requires biological or alloplastic materials. In rhinoplasty, a frequent postoperative problem is a rough and rigid nasal dorsum. The purpose of this experimental study was to investigate the feasibility of using diced cartilage grafts wrapped in amniotic membrane for soft tissue augmentation.
Methods:
Diced cartilage grafts wrapped with amniotic membrane were transplanted to a subcutaneous tunnel that was made in the back in 20 rats. After 2 months, the histopathologic changes that occurred in the grafts were examined by light microscopy.
Results:
When the diced cartilage grafts wrapped in amniotic membrane were examined, each graft displayed different viability rates.
Conclusions:
In soft tissue augmentation, especially in the nasal dorsum, amniotic membrane can be used to keep the diced cartilage viable and adjoined.
