<unk>  is a largely obsolete surgical procedure in which a cannula is inserted into the maxillary sinus via the inferior meatus to allow irrigation and drainage of the sinus. It is also called proof puncture, as the presence of an infection can be proven during the procedure. Upon presence of infection, it can be considered as therapeutic puncture. Often, multiple repeated<unk> s are subsequently required to allow for full washout of infection. In contemporary practice, endoscopic sinus surgery has largely replaced<unk>  and as such, it is rarely performed.
