摘要
FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely to maxillofacial surgery and orthodontics. Bone reconstructive surgeries are simulated on face part of skull in children with acquired deformation of lower and upper jaws, associated with temporomandibular joint anchylosis after hematogenous osteomyelitis and/or birth trauma. Wherein MR examination of skull is made with subsequent reconstruction in 3D programs to create three-dimensional model of skull. Facial bones pathology is detected, surgical treatment of model is performed virtually. Before surgical management 3D cephalometry is made at obtained three-dimensional model of skull, taking into account age peculiarities. At 3D model of skull main cephalometric marks are placed manually at maximum increase in screen resolution, using simultaneously different projections: perspective, right, left, top, front and varying transparency of image from 0 to 100 %. 29 cephalometric parameters are used: 14 angular - ∠NSeBa, ∠Ii-MP, ∠ANB, ∠ANSe, ∠BNSe, ∠PgNSe, ∠NSe-MP, ∠MeNSe, ∠NSeMe, ∠NSeGn, ∠FH-MP, ∠I, ∠B, ∠Go and 15 linear - N-Se, Se-Ba, N-Me, N-SpP, SpP-Me, Se-Go, N-Go, Se-Gn, A'-Snp, Is-ms, Pg-Go, Ii-mi, Go-Co, m-i, Ba-Br. On basis of obtained data 3D modelling of surgical management with subsequent virtual correction of jaw bone is made during the staged orthodontic-surgical treatment.;EFFECT: method enables dynamic monitoring of changes of cephalometric parameters in patient's growth and simulation of further staged orthodontic-surgical management in children and predicting results of staged treatment until child's growth, as well as reducing probability of unplanned staged operations due to production of 3D model of skull and arrangement of main cephalometric marks manually.;1 cl, 24 dwg, 2 ex
