Prevalence of complications of maxillary sinus grafts

Objective: Prevalence of complications of maxillary sinus grafts by reviewing medical records (2010-2020) in Implantology Oral. Method: Retrospective analytical research. Approved by the Ethics Committee as risk-free research. Clinical patients undergoing dental implant surgery, with any type of maxillary sinus graft (2010 – 2020), radiographic or tomographic controls of the maxillary sinus and clinical controls 8 -30 days post-surgery, sample 65. Variables: age, gender, systemic status, habits, date and type of surgery, type of graft, use of fibrin-rich (PRF) or platelet-rich (PRP) plasma, surgical technique (side window), simultaneous implant placement, periodontal status. complications: rupture of sinus membrane, displacement of the implant (sinus cavity), hemorrhage, hematoma, pain, edema, flushing, dehiscence suture, membrane exposure. Results: Sample 65: Women 39 (60%), average age 57.49 years, men 26 (40%) average age 57.85 years, non-smokers 58 (89%), absence of cardiovascular diseases 57 (87.7%), reduced periodontium 50 (76.9%). Used surgical technique "Side window" 56 patients (86.15%), rupture of the sinus membrane 17 (26.15%); did not need growth factor46 (73.85%), use of alloplastic graft (29.23%). At 30 days absence of: pain (96.92%), edema (95.38%), hematoma (96.92), tissue dehiscence (96.92), no displacement of the implants (100%) There was no significant association between the surgical technique and the presence of each of the complications (Chi square p= 0.606), (Pearson p=0.332), with no significant association between growth factor use and complications (Chi square p=2.131), (Pearson p=4.9996). Conclusion: Rupture of the sinus membrane is the intraoperative complication with the highest prevalence (26.15%) in maxillary sinus graft surgeries, with the lateral window technique.
