Abstract
OBJECTIVE: To demonstrate the development of the paranasal sinuses in a pediatric population by computed tomography scans. STUDY DESIGN: Radiology records at a tertiary care institution were reviewed for the computed tomography scans of the face, orbit, or paranasal sinuses in patients aged 0 to 12 years. METHODS: Computed tomography scans were reviewed by a head and neck radiologist and otolaryngologist for the development of the frontal, maxillary, ethmoid, and sphenoid sinuses. The size of the pneumatized paranasal sinuses was measured in two planes and graded on a scale of 0 to 3. Ossification of the maxillary crest and vomer, obliteration of the foramen cecum, and development of agger nasi cells, Haller cells, and the superior turbinate were studied. Patients with syndromes, nasal stenosis, choanal atresia, or cystic fibrosis were excluded from the study. RESULTS: In all, 91 computed tomography scans in 66 patients were studied. Serial development could be followed in 16 patients who underwent repeat scans. Patients were divided into six age cohorts based on their age at the time of the scan: 0 to 3 months (10%), 3 to 12 months (13%), 1 to 3 years (13%), 3 to 5 years (20%), 5 to 8 years (29%), and 8 to 12 years (16%). Ethmoid sinuses were the first to fully develop, followed sequentially by maxillary, sphenoid, and frontal sinuses. Each sinus has a rapid rate of development during specified age cohorts. CONCLUSION: The results will aid the physician when correlating the clinical and radiographic findings of pediatric patients aged 0 to 12 years who are being evaluated for sinus disease and potential surgical intervention.
