Absence of pneumatization on the expected location for frontal sinuses.
Case Discussion
Frontal sinus aplasia is present unilaterally in 15% and bilaterally in 5% of normal adults.
Paranasal sinus aplasia and hypoplasia may lead to misdiagnosis on routine X-rays as it could be mistaken for infections or mass lesions.
The prevalence of frontal and sphenoidal sinus aplasia or hypoplasia have been shown to be higher in patients with cystic fibrosis or primary ciliary dyskinesia.
