Can wisdom tooth extraction be a common treatment for maxillary sinusitis?

No: True maxillary sinusitis is an infection of the lining of the sinus. While upper wisdom teeth reside adjacent to that sinus, it is hoped that their removal leaves the sinus intact, in which case the removal does nothing to treat the infection. Antibiotics generally are the treatment of choice for such in infection.

Not a common treatmn: Not common. It could be the right treatment. Get an opinion from an ENT (ear nose and throat) specialist to ensure that the wisdom teeth are the source of the sinusitis.
