A 50-year-old male patient had sinus augmentation on his right side. However, postoperatively, his symptoms were protracted. A CT scan showed thickening of the Schneiderian membrane and scattered graft material. Management included endoscopic nasal examination and ostium enlargement, antibiotic coverage, and full enucleation of the graft and diseased tissue.Conclusion:
Patency of the sinus ostium should be carefully evaluated before sinus lift/grafting procedure using CT technology. Radiology and otolaryngology consultations may be necessary to rule out ostium stenosis before surgery.
