I am writing in regard to the article titled "Bacteriology of Acute and Chronic Frontal Sinusitis," which appeared in the May 2002 issue of the ARCHIVES.1 My first comment is regarding the method that was used to collect the specimens: "The specimens were obtained during surgery, using strict asepsis . . . ." No mention is made as to whether the specimens were obtained through open sinus surgery, directly from the frontal sinus itself, or transnasally, and it has been proved in several studies that it is very difficult to ascertain the validity of bacteriologic findings in specimens from any of the sinuses because of contamination.
