Diversity of opinion exists among otolaryngologists regarding the impo
rtance of preserving the middle turbinate during sinus surgery. The pu
rpose of this study is to determine whether or not middle turbinate re
section has a bearing upon postoperative disease within the frontal si
nus. In this retrospective analysis of 110 consecutive patients with c
hronic or recurrent acute sinusitis, 69 tense group) had previous midd
le turbinectomy and 41 patients (control group) had intact middle turb
inate after prior sinus surgery. In 42 patients, CT scans were scored
and defined as having either mild-moderate or severe disease. Frontal
sinusitis seen on CT scan was present in 75% (30 of 40) of case sides
and 45% (9 of 20) of control sides, and this difference was significan
t (P < 0.05). The height of middle turbinate resection was measured, a
nd there was no statistical difference in frontal sinusitis between pa
tients with high and low resection. Therefore, this work does not supp
ort the concept that middle turbinate resection results in a lower inc
idence of frontal recess disease.
