I did a sinus lift 4 weeks ago. There was a tear of the sinus membrane in the distal part of the sinus measuring 5 mm. I proceeded with the lift and placed a collagen membrane covering the defect and fill the sinus with Biooss. The repair was done using a loma linda pouch technique The patient had antibiotics prior and then 10 days after surgery.
4 weeks later the patient presents with swelling, puss and granules coming out her nose.
How would you approach this? Can I recover? Do I get an ENT involved?
