Abstract
|
|
|
Background and Objectives: The paranasal sinuses present considerable diversity inthe degree of pneumatization in pediatric age group. However, the developmental pattern and degree of pneumatization of the sphenoid sinus in children has
not
been
well understood. This study was designed to evaluate the multiplanar developmental pattern of the sphenoid sinus pneumatization in children using magnetic resonance (MR) imaging technique. Materials and Methods: The MR images of the
sphenoid
sinus in 152 children with ages ranging from 2 months to 163 months were retrospectively reviewed. The degree of pneumatization was independently analyzed both in axial and sagital image, and then correlated with aging of the studied children.
Results: The sphenoid sinus pneumatization was identifiable as early as 2 months of age on axial image, and at 4 months of age on sagittal image. The sphenoid sinuses were unexceptionably pneumatized at the age of 3 on axial image and at
the
age
of 6 on sagittal image. At the age of 9, all the children showed pneumatization of grade 2 or more on both axial and sagittal images.
