Role of keratinocytes in wound contraction: an impact assessment using a model of collagen matrix populated with fibroblasts

Rev. bras. cir. plást; 26 (3), 2011
BACKGROUND: The possible participation of keratinocytes in wound remodeling has been widely studied. This study investigated the impact of keratinocytes in wound contraction. METHODS: Murine type I collagen gels populated by human fibroblasts and seeded with human keratinocytes on the surface to form a d...

Tissue expansion at Hospital de Clinicas-UFPR: our experience

Rev. bras. cir. plást; 26 (3), 2011
BACKGROUND: The shortage of tissue for large defect reconstruction is a challenge for the plastic surgeon. Tissue expansion emerged in this context, and in the last 30 years has become one of the most widely used modalities in reconstructive surgery. Tissue expansion is a very versatile technique that ca...

Versatility of the bilobed flap

Rev. bras. cir. plást; 26 (3), 2011
BACKGROUND: The bilobed flap is a double transposition flap. Its geometric structure enables a better distribution of tensile forces along its rotation axis, avoiding the skin distortions and redundancy generated by other flaps or primary sutures. The bilobed flap can be made with axial and random vascul...

Ear reconstruction after traumatic injuries

Rev. bras. cir. plást; 26 (3), 2011
BACKGROUND: Congenital or traumatic ear deformities are difficult and complex issues in plastic surgery due to the increasing number of cases and high degree of difficulty involved in surgeries to restore facial harmony. The authors assessed the techniques used in ear reconstruction, their complications,...

Use of the vermilion myomucosal flap with or without the mentolabial skin flap for lower lip reconstruction

Rev. bras. cir. plást; 26 (3), 2011
BACKGROUND: Several techniques that have been described for reconstructing the lower lip often produce microstomia, commissure distortion, functional impairment, and decreased sensitivity. A technique for preserving neuromuscular tissue during a single-stage lip reconstruction is reported in this study. ...

Minimally invasive lift of the middle third of the face using musculoaponeurotic suspension with periosteal fixation technique: a review of 50 cases

Rev. bras. cir. plást; 26 (3), 2011
BACKGROUND: At present, demanding workplaces in our society cause patients to search for less invasive procedures with diminished morbidity and more rapid healing to meet their cosmetic requirements. A combination of several new noninvasive procedures allows significant facial changes, achieving a youthf...

Frontal and glabellar myotomy: single short frontal scar approach

Rev. bras. cir. plást; 26 (3), 2011
BACKGROUND: Frontal and glabellar muscle hyperactivity with consequent wrinkles are frequent complaints in plastic surgery. Treatment consists of impediment of related muscles; this can be achieved by application of botulinum toxin or surgery by means of classic coronal incision, endoscopic approach, tra...

Single block costal cartilage graft in rhinoplasty

Rev. bras. cir. plást; 26 (3), 2011
INTRODUCTION: It is often necessary to use inclusion materials in rhinoplasty for nose restructuring. The costal cartilage graft is one of the inclusion material options, and its use is indicated when septal cartilage is not available or is not sufficient to provide necessary remodeling of the nose. METH...

Filling the nasal dorsum with Gore-tex in rhinoplasties

Rev. bras. cir. plást; 26 (3), 2011
BACKGROUND: Many autogenous and exogenous materials have been frequently used for the production of grafts and implants in rhinoplasties. The ideal graft or implant should be biocompatible, biointegrated, non-absorbable, and easily moldable and should not cause an inflammatory response. Gore-tex, an expa...

"Double duck" nasolabial lifting

Rev. bras. cir. plást; 26 (3), 2011
BACKGROUND: During aging, the vermilion border of the upper lip wrinkles, stretches, and inverts because of the sphincteric action of the orbicularis oris muscle. Furthermore, a decrease of the nasolabial angle can be observed because of maxillary retropositioning. Most techniques for lip shortening do n...
