Abstract:
Objective To explore the normal aerification of paranasal sinuses in Chinese children with magnetic resonance imaging. Methods Two hundred and eighty Chinese children aged from 17 days to 14 years without any symptoms related to sinusitis were statistically analyzed in MRI features, including counting the number of paranasal sinus pneumatization and the maximum axial and sagittal area of the left maxillary. Results The pneumatization rate of maxillary sinus was 85% in children aged from 0 to 1 years.Until 3 years the pneumatization rate of maxillary sinus was 95% and there was no significant difference in boys and girls( x2 = 0. 741, P = 0. 389 ). The pneumatization rate of maxillary sinus reached 100% after 4 years old. The pneumatization rate of ethmtoid sinus was 100% in this study. The pneumatization rate of sphenoid sinus was 0 within 1 year old, 49% within 4 years old and 100% after 7 years old. There was no significant difference in boys and girls on the pneumatization rate of sphenoid sinus ( x2 = 2. 452, P =0. 117 ). The pneumatization rate of frontal sinus was 0 within 5 years old, 62% within 9 years old and 95% after 10 years old. There was no significant difference in boys and girls on the pneumatization rate of frontal sinus(x2 =0. 124,P =0. 724). The axial and sagittal maximum area of maxillary sinus was (689. 28 ±221.79) and (659.76 ±263.31 )mm2 in girls and (668. 13 ±206.38) and (638.60 ±207.67) mm2 in boys. The differences were significant( t = - 19. 78 ,P <0. 001 ;t = - 19. 89 ,P <0. 001 ). Conclusion The study of the development and normal aerification of paranasal sinuses of children can help radiologist make correct diagnosis of paranasal sinuses in children.
