Use of Plasma Rich in Growth Factor for Schneiderian membrane management during maxillary sinus augmentation procedure

The aim of this pilot study was to present a novel technique for the management of the Schneiderian membrane during maxillary sinus lift surgery using Plasma Rich in Growth Factors (PRGF).Eight maxillary sinuses were augmented in 8 patients. Two small perforations of the Schneiderian membrane occurred during lifting procedure, which were solved using PRGF clot before grafting the site with PRGF and anorganic bovine bone. With the exception of one patient who experienced pain, following an acute sinus infection after three days of uneventful healing, postoperative patients' quality of life was generally good. The most common complication (50% of cases) was hematoma which disappeared after one week.Despite the limitations of this study, concerning the sample size and the study design, the use of PRGF may be helpful in reducing complications following sinus lift surgery. More well-designed studies, with larger sample size, are needed to validate this protocol.
