Preoperative chronic sinusitis as significant cause of postoperative infection and implant loss after sinus augmentation from a lateral approach.

Objectives: Among intra/postoperative complications of sinus augmentation from a lateral approach, postoperative infection and implant loss are particularly important because they have irreversible consequences. The purpose of this study was to determine the causes of postoperative infection and implant loss after a lateral approach and to determine the appropriate prophylaxis and therapy.

Materials And Methods: In total, 109 patients (121 sinuses, 252 implants) were included in this study.
