Abstract:
Introduction. Maxillofacial fissures are the most common form of congenital malformations of the face
and the maxillofacial region. These forms of malformations may vary from simple shapes to particularly
non-specific forms. The cleft lip and palate are characterized by anatomical and functional disorders. In
unilateral total splits, anatomical disorders are characterized by bone deformities. The upper jaw is divided
into two segments by the fissure that passes on the upper lip, alveolar and hard palatal process and soft
palatal region. The clinical manifestations of these forms of malformations appear with severe aesthetic
facial deformities and functional disorders that can lead to a chain of clinical diseases that endangers even
the vital functions of the child.
Methods and materials. Six patients with total palatal splitting were examined. There were impressions
and obtained study gypsum models during preoperative to the primary stage of plasty and postoperatively
to the secondary stage of plasty of the hard palate.
Results. According to the measurements and calculations, we came to the conclusion that the two-stage
plasty, only with passive therapy of separation of the nasal cavity from the oral cavity with the help of
palatal plates, has a displacement efficiency of the splitting segments of 46%, while one-stage palatal plasty
with active preoperative nasal-alveolar molding with intermaxillary traction has a closure value of 76%
(after Elcin).
Conclusion. Two stage hard palate plasty adapts the soft tissues to remove the recurrence of the dehiscence
of cleft edges of the hard palate.
