Background and Objectives For safe sinus surgery, it is essential to understand the anatomicalstructure and developmental state of the paranasal sinuses. Structural abnormalies such asaplastic and marked hypoplastic sinuses may not be amenable to sinus surgery or balloonsinuplasty. The purpose of this study is to evaluate the degree of pneumatization of the frontaland sphenoid sinuses in Korean adults. Subjects and Method This retrospective study utilized CT images of 1190 sides from 595Korean adults. The frontal sinus was classified into normal, hypoplasia, aplasia and unilateralhidden aplasia. The sphenoid sinus was evaluated the incidence regarding the aplasia and unilateralhidden hypoplasia. Results Bilateral frontal sinus hypoplasia was observed in 8.5% of women and 4.2% of men(p＜0.05), while unilateral frontal sinus hypoplasia was found in 3.5% of women and in 4.8%of men (p＞0.05). Bilateral frontal sinus aplasia was observed in 7.1% of women and 2.9% ofmen (p＜0.05), while unilateral frontal sinus aplasia were found in 7.1% of women and in 5.4%of men (p＞0.05). Unilateral hidden frontal sinus aplasia was observed in 1.7% of women and1.5% of men (p＞0.05). There was no bilateral sphenoid sinus aplasia and only one woman hadunilateral sphenoid sinus aplasia. Unilateral hidden sphenoid sinus hypoplasia was observedin 1.4% of women and 2.9% of men (p＞0.05). Conclusion Bilateral frontal sinus hypoplasia and aplasia are more common in women thanin men. Although the incidences of unilateral hidden frontal sinus aplasia and hidden sphenoidsinus hypoplasia are low, sinus surgeons should carefully review CT for sinus surgery or balloonsinuplasty.
