Abstract

To obtain baseline standards of normal age-related development of thesphenoid sinus during childhood magnetic resonance images of the sphenoid sinus in 401 patients less than 15 years old were reviewed. T1-weighted sagittal and T2-weighted axial scans were evaluated for bone marrow conversion, development of pneumatization, spatial enlargement and septation of the sphenoid sinus. The sphenoid sinus had a uniformelylow signal intensity (red bone marrow) on T1-weighted images in all children less than 4 months old.-Signal intensity changes from hypo- tohyperintense (bone marrow conversion) started at age of 4 months. Onset of pneumatization was observed in 12% of the patients at age 13-15 months. By age 43-48 months, 85% of the patients showed pneumatizationof the anterior part of the sphenoid bone. Pneumatization was complete in all patients older than 10 years. Enlargement of the sinus showeda characteristic profile in each dimension. Median septation was observed irregularly with age, with a maximum of 77%. Septum variants werenoticed between 4.5% and 20%. The recognition of this phenomenon may serve as a reference for evaluating normal and abnormal development ofthe sphenoid sinus and may be of great value for diagnostic and therapeutic management of pathologic conditions of the child's sphenoid sinus and its surrounds.
