Overview

Objective: The objective of this study is the analysis of the development of ethmoid air cells and maxillary sinus by measuring their volume by the high resolution computed tomography. The measurements were done on children from the age of 0 to 18. The knowledge of the development of paranasal sinuses has a clinical importance especially for the diagnosis and medical treatment of children´s rhinosinusitis and its complications.

Methodology: The children, who were included in this retrospective study, underwent the high resolution computed tomography of the head from different purposes than the patological diagnosis of paranasal sinuses. The patients were distributed into groups according to their age (0-1, 1-2, 17-18). The three-dimensional reconstruction and the capacity assessment were performed by means of the software OsiriX v. 5.8.1. The maxillary sinus and ethmoid air cells were measured. The results were statistically processed.

Results: There were 180 patients included in this study (10 patients in each category 0-18). The paranasal sinuses were measured on both sides in all categories, i.e. there were 360 measurements in total. The maxillary sinus was present in the age group of 0 to 1 in 100% of all cases (volume 0,8 ml). At the age of 5 years, maxillary sinus volume was 3.8 ml, at the age of 10 years - 6.8 ml and at the age of 18 years the average volume of maxillary sinus was 20.7 ml. The ethmoid air cells were present in the age group of 0 to 1 in 100% of all cases (volume 0,4). At the age of 5 years, ethmoid air cells volume was 1.4 ml, at the age of 10 years - 3.4 ml and at the age of 18 years, the average volume of ethmoid air cells was 4.8 ml.

Conclusion: The results of this study show that ethmoid air cells and maxillary sinus are develop at the age of 1year in 100% of all cases. The results of this study do not allow us to draw a conclusion on the end of the development of the maxillary sinus and ethmoid air cells. Considering the shape of the developmental curves, it is possible to presume that their development is finished later than 18.
