ABSTRACT
BACKGROUND AND

OBJECTIVES:

For safe sinus surgery, it is essential to understand the anatomical structure and developmental state of the paranasal sinuses. Structural abnormalies such as aplastic and marked hypoplastic sinuses may not be amenable to sinus surgery or balloon sinuplasty. The purpose of this study is to evaluate the degree of pneumatization of the frontal and sphenoid sinuses in Korean adults. SUBJECTS AND

METHOD:

This retrospective study utilized CT images of 1190 sides from 595 Korean adults. The frontal sinus was classified into normal, hypoplasia, aplasia and unilateral hidden aplasia. The sphenoid sinus was evaluated the incidence regarding the aplasia and unilateral hidden hypoplasia.

RESULTS:

Bilateral frontal sinus hypoplasia was observed in 8.5% of women and 4.2% of men (p 0.05). Bilateral frontal sinus aplasia was observed in 7.1% of women and 2.9% of men (p 0.05). Unilateral hidden frontal sinus aplasia was observed in 1.7% of women and 1.5% of men (p>0.05). There was no bilateral sphenoid sinus aplasia and only one woman had unilateral sphenoid sinus aplasia. Unilateral hidden sphenoid sinus hypoplasia was observed in 1.4% of women and 2.9% of men (p>0.05).

CONCLUSION:

Bilateral frontal sinus hypoplasia and aplasia are more common in women than in men. Although the incidences of unilateral hidden frontal sinus aplasia and hidden sphenoid sinus hypoplasia are low, sinus surgeons should carefully review CT for sinus surgery or balloon sinuplasty.
