Abstract
PURPOSE
The aim of the study was to analyze the eligibility of resorbable collagen membrane in the treatment of midfacial fractures to prevent gap formation and subsequent cheek tissue retraction.
MATERIAL AND METHODS
We included nine patients (six males, three females; mean age 51; range 20-73 years; mean bone gap size 8.03 × 13.12 mm) in a retrospective study design. The defect size was assessed by ultrasound.
RESULTS
After a healing period of 4 to 55 weeks, treatment resulted in a significant reduction of gap size (residual mean bone gap size 6.14 × 7.32 mm).
CONCLUSIONS
Native resorbable collagen membrane is a promising tool to reduce the size of bony gap in midfacial defects.
