Background & Objectives: Endoscopically guided middle meatal culture is recommended to determine organ-specific antibiotic therapy in sinusitis. This study was designed to decrease the chance of contamination in endoscopically guided middle meatal swab through a shielded pathway using a sterile straw to bypass the contaminated area in the nose from the vestibule to the middle meatus.
Subjects & Method: Seventeen healthy volunteers underwent endoscopically guided middle meatal culture. With or without the sterilization of the nasal vestibule, endoscopically guided middle meatal culture was performed by using a sterile cotton swab (routine swab) and using a sterile cotton swab through a sterile straw (shielded swab). We compared the contamination rates between the routine swab versus shielded swab.
Results: With and without the sterilization of the nasal vestibule, the contamination rates of the routine swab was 11.7% and 64.7%, respectively and the contamination rates of the shielded swab was 5.8% in both.
Conclusions: In endoscopically guided middle meatal culture, the contamination rates was significantly decreased by using the shielded swab without sterilization of the nasal vestibule. This study suggests that the shielded swab is a new and reliable swab method that can be used easily and simply at the office.
