Abstract

Background and Objectives : Although there are abundant reports on the embryology
and the development of paranasal sinuses, few studies were performed with respect to
the normal development of paranasal sinuses with magnetic resonance(MR) imaging,
especially in Korean children. This study was designed to evaluate the normal
development of paranasal sinuses in Korean children with MRimaging.
Materials and Methods : MR images of the paranasal sinuses in 400 children under the
age of 15 were reviewed retrospectively.
Results : In all cases, maxillary and ethmoid sinuses were pneumatized. At the age of
less than 1, anteroposterior(AP), transverse and vertical lengths of the maxillary sinus
were 15.8±4.2mm, 9.4±3.1mm, and 8.9±3.0mm respectively. By the age of 11, the
growths of AP(36.7±2.3mm) and transverse(27.6±4.4mm) lengths of the maxillary sinus
ceased. By the age of 13, the growth of vertical(37.8±5.0mm) length of the maxillary
sinus ceased. At the age of less than 1, AP and transverse lengths of the ethmoid sinus
were 27.0±3.3mm and 5.4±1.2mm, respectively. By the age of 10 and 12, the growths
of AP(41.1±2.0mm) and transverse(11.7±1.7mm) lengths of the ethmoid sinus ceased.
The spheroid sinus pneumatization was identifiable as early as 33 day of age in an axial
view and at 4 months of age a sagittal view of MR image. The spheroid sinuses were
pneumatized in almost all children older than 2 years. By the age of 12, the growth of
transverse length of the spheroid sinus ceased. However, AP and vertical lengths of the
spheroid sinuses continued to grow until the age of 15.
Conclusion : The results of this study may be helpful in the management of sinus
diseases in children.
