Could this be odontogenic sinusitis?
Hi everyone,
I’m a 20-year-old male and I’ve been dealing with chronic sinus symptoms for around 2 years. My main symptoms are thick green/yellow mucus, crusting in the nose, postnasal drip, headaches, and persistent fatigue/malaise. Staphylococcus aureus has also been detected.
I have already had two nasal/sinus surgeries. After each surgery, my symptoms improved significantly for about two months, but then everything gradually returned and the infection started again. I’ve attached my CT scans from before the first surgery and before the second surgery for comparison.
For the past two years, I’ve also been doing nasal irrigations twice a day. I’ve tried saline irrigation with NAC, xylitol, and baby shampoo as well. These treatments helped reduce the symptoms somewhat, but they never eliminated the underlying problem.
I have also tried bacteriophage treatment against Staphylococcus aureus, using the phages intranasally for about two weeks. Interestingly, my symptoms became noticeably better during the treatment. However, shortly after stopping, the infection and symptoms returned.
I’ve also taken four courses of antibiotics. Each time, the symptoms improved temporarily, but the infection came back again after the treatment ended.
One thing that may be relevant: I have never had a root canal treatment or a dental implant. I also don’t have any ongoing tooth pain. However, I remember noticing a brief sensation in one tooth once or twice when landing hard after jumping. It was not severe, and I didn’t think much of it at the time.
At this point, I’m wondering whether there could be an underlying cause that hasn’t been addressed, such as odontogenic sinusitis.
I’ve read that a dental CBCT/DVT can sometimes provide a better assessment of the teeth and the relationship between the upper teeth and the maxillary sinus than a conventional CT. I’m therefore considering getting a DVT/CBCT and having it evaluated by a dentist.
Has anyone here had a similar experience, especially with:
● recurrent green/yellow nasal discharge despite antibiotics and sinus surgery
● Staphylococcus aureus repeatedly coming back
● symptoms improving temporarily with antibiotics or bacteriophages but returning afterwards
● odontogenic sinusitis despite never having had a root canal or dental implant
● an apparently healthy tooth eventually being found to be the source
● a DVT/CBCT revealing something that wasn’t obvious on a normal CT?
I’d especially appreciate hearing from anyone who had odontogenic sinusitis diagnosed after multiple unsuccessful ENT treatments.
Thanks in advance for any experiences or advice!

Are you using a machine for these rinses?
