ISSUE OF DETAILING THE CLASSIFICATIONS OF CONGENITAL CLEFT UPPER LIP AND PALATE

Abstract

Subject. Congenital cleft of the upper lip and palate is one of the most common malformations of the maxillofacial region which percentage is 86-88 %. This defect causes a complex set of anatomical and functional changes in the structures of the face and palate, it negatively affects the development of the child's body, therefore, it requires competent definition and extensive professional knowledge on its systematization and early elimination. The purpose of research — study of the incidence of asymmetric cleft lip and palate on children and complement the clinical and anatomical classification of clefts options asymmetry of the affected tissues. Methodology. There was carried out a retrospective statistical analysis of case histories of 687 patients with congenital cleft of the upper lip and / or palate, who received treatment on the basis of State Autonomic Health Institution of the Sverdlovsk Region Multiprofile Clinical Medical Center «Bonum» for the period 2015—2019 with the determination of the variety of types of lesions. Results. Asymmetry of the affected tissues occurred in 8.59 % of cases of the total number of children (687 patients) who was born with maxillofacial pathology of the upper lip and palate which required clarification of the clinical anatomical classification and the choice of individual treatment tactics. A clinical and anatomical classification that takes into account asymmetric clefts of the upper lip and palate was proposed. Conclusions. The allocation of asymmetric clefts of the upper lip and palate into certain groups of lesions and an assessment of their frequency made it possible to present a classification of this type of defect, which expanded the idea of the variety of anomalies of the maxillofacial region. The classification we proposed takes into account in more detail the clinical features of the congenital cleft of the upper lip and palate and, thus, more fully meets the clinical requirements and international standards, which allowed us to develop new methods of surgical treatment of congenital cleft of the upper lip and palate, as well as to build management tactics for such patients together with other specialists.
