Abstract

BACKGROUND AND OBJECTIVES
Outfracture of the inferior turbinate (IT) is a less invasive procedurethan all other reductive turbinate surgeries. The aim of this study is to investigate the anatomical factors of IT affecting outcomes of outfracture of the IT. MATERIALS AND METHOD: This study comprises 206 cases of 103 patients who underwent outfracture from 2006 to 2012. Patients weregrouped according to good outcome and poor outcome,based on postoperative endoscopic assessments after decongestion. Angle and length of IT, width of IT head, and the distance of the IT to the lateral nasal wall were compared at three different sections viacomputed tomography.
RESULTS
Significant differences in the length and angle of IT between the two groups were not found. The width of the IT head in the good outcome group was narrower than that in the poor outcome group. The distance of the IT to the lateral nasal wall was longer in the good outcome group, compared with that of the poor outcome group. These differences were especially prominent at the middle and posterior sections.
CONCLUSION
This study suggests that some anatomical factors, especially the width of the inferior meatus, could play a role in affecting the outcome of outfracture IT surgery.
