Сравнительное морфометрическое изучение носоглоточного пространства у детей с хроническим аденоидитом и челюстно-лицевой дизморфией

Abstract

The growth and function of the nasal cavity, nasopharynx, and oropharynx are closely related to the normal growth of the skull in children. The lack of theoretical knowledge, the demand for knowledge, the complexity of prediction impelled the authors to conduct a comparative morphometric study of MRI scans of the nasopharyngeal space in children with chronic adenoiditis and maxillofacial dysmorphism to search for a rational approach and technology that preclude the progression of irreversible craniofacial changes. The study was performed by a group of authors in the premises of the University clinic. A total of 490 patients suffering from chronic adenoiditis were examined. The authors established the prevalence of comorbid pathology of chronic adenoiditis with hypertrophy of the pharyngeal tonsil and neurological pathology of the brain, which allowed substantiating the performance of brain MRI, it constituted 3.2%. This comorbid pathology was studied in conjunction with the acquired maxillofacial dysmorphism. For statistical calculation, the authors chose non-parametric methods with the use of affine relationships space theory from the section of Riemannian Geometry. The authors pointed out topographic landmarks and formed the control points which made it possible to evaluate the nasopharyngeal spaces, changing under the effect of the pharyngeal tonsil, taking into account the complexity of the anatomical three-dimensional structure. The measurements and control point calculations were carried out using the software RadiantDicomViewer v4.2 Identification of the dependence made it possible to calculate the adeno-nasopharyngeal index, which provides the assessment of maxillofacial dysmorphism risk and its reversibility.
