Features of Morphometric Parameters of the Nasopharynx and Adenoids in Children

Introduction. The study of relationship between nasal obstruction syndrome, adenoids, cephalometric indicators is relevant.

Research objective is to identify the relationship between the size of the nasopharynx and adenoids and the size of the facial skull in children aged 4–7 years, in order to select the appropriate instruments and improve the results of surgeries in clinical practice.

Materials and methods. 79 CT scans of children’s heads aged 4–7 years of both sexes were evaluated сraniometric parameters of facial skeleton from piriform aperture to the hoanas.

Results. The height of nasopharynx is related to width of inferior nasal passage in anterior region, excluding mucous membrane of nasal concha, height of vomer, and width of choana; its length — to thickness of nasal septum in anterior region; its width — to total width of choana; height of adenoids — to total width of choana and width of piriform aperture, in boys the height of adenoids is 1.724 mm less than in girls of the same age; their length — to thickness of lower nasal turbinate on the right in posterior region and width of choana.

Conclusion. In children 4–7 years, the size of the nasopharynx can be calculated based on the identified dependencies from the size of the facial skull, which is important for adenotomy to select instruments and improve the quality of operations. It is not advisable to use regression equations to calculate the size of adenoids based on the size of the facial skull n children aged 4 to 7 years.
