Maxillary sinus infection

In this post, I will upload the treatment process for the infected case after the Windows app.

This is a male patient in his mid-50s.

A window approach was performed in the left maxillary sinus, but the patient was referred due to symptoms of infection, including the presence of pus in the surgical site.

Based on the CT findings, signs of infection are evident in the left maxillary sinus.

There is a history of medication for over 3 weeks, but there was no improvement.

Irrigation of the left maxillary sinus was performed through the oral cavity by inserting a drain as shown in the image.

During this procedure, a significant amount of pus drainage was observed.

Irrigation of the maxillary sinus was performed twice a week with a one-week interval, and it was confirmed that no pus was coming out. The drain was subsequently removed.

During irrigation, some of the transplanted bone came out, but the internal bone was intentionally not removed.

A month later, in the photo, there are no symptoms of maxillary sinusitis, and the CT findings indicate signs of healing.

In the photo taken about 4 months later, more healing is evident, and there are signs of retained transplanted bone.

This is a photo taken about 5 months later.

This is an intraoral photo. After careful consideration, implant placement was performed using the remaining bone with the additional procedures of crestal approach and bone grafting.

Final prosthesis after 5 months.
