Abstract:
To evaluate the normal development of the paranasal sinuses in children with CT, authors prospectively studied with brain CT scans of 260 children without known sinus diseases, ranging in age from 7 days to 16 years. Maximal anteroposterior and transverse diameters(mm) and maximal cross-sectional area(mm2) of both sides of the maxillary sinus were measured with the aid of computer device. As to the ethmoidal and sphenoidal sinuses, we simply documented the presence of the aplastic ethmoidal sinus and calculated the age-incidence of the sphenoidal sinus pneumatization, respectively. There noted three phases in the development of the maxillary sinus. The anteroposterior and transverse diameters of the maxillay sinus increased nearly in parallel. The former was always greater than the latter. In no cases was the ethmoidal sinus aplastic and almost all sinuses were pneumatized even in infants as early as 7 days old. CT identified the conchal pattern of sphenoidal sinus pneumatization in infants as early as 11 days old. Sphenoidal sinus pueumatization was seen in 38% of the children under the age of 1 year, 82% of the children between the age of 1 and 2 years, and almost all children older than 2 years. The anteroposterior and transverse diameters of the maxillary sinus seem to reach the adult size by 8 years of age, and the conchal pattern of sphenoidal sinus pneumatization can be recognized earlier with CT than on the plain radiographs.
