Modern aspects of interdisciplinary treatment in children with bilateral cleft lip and palate

Abstract

According to the World Health Organization incidence of cleft lip and palate ranges from 0.6-1.6 cases per 1000 newborns per year. Thus, bilateral full cleft lip and palate occurs less frequently around 15–25%. Purpose: to analyze treatment methods for children with bilateral cleft lip and palate during the period of a removable bite. A review of 51 literature sources from 1951 to 2019 was carried out. Occlusion development features in bilateral cleft lip and palate patients during mixed dentition period were analysed. Main anatomical features of the maxillofacial region in children with bilateral cleft lip and palate during mixed dentition period is narrowing of the upper and lower dental arches as well as presence soft tissues scars of the upper lip. The main methods of treatment for such children is surgical reconstructive operations, including the elimination of the anatomical defect of the hard palate using mucoperiosteal flaps from the lateral parts of the hard palate combined with orthodontic treatment methods. Thus, an integral method of treating children with bilateral cleft lip and palate during mixed dentition period is a comprehensive approach, including surgical reconstructive operations, as well as orthodontic treatment, the main purpose of which is to expand and extend dental arch, which results in normal occlusion therefore eliminating myofunctional disorders. Key words: cleft lip, cleft palate, mixed dentition, occlusion features, orthodontic treatment
