The patients with endoscopic signs of ostium obstruction and/or adhesion formation as complications.

Other endoscopic findings −: no; +: yes; adhesions: ++++: ostium severely restricted, +++: from lateral wall of middle meatus to middle turbinate, ++: from middle turbinate to septum, +: from lower turbinate to septum; 1patients with missing data, thus the 3-month postoper. data was used, +2: the ostium was widely open in sinus CT scans 9 months postoperatively; ?: the maxillary sinus mucosa was not seen; M: male, F: female; d.: days; m.: months.
