[The use of «growing» endoprostheses in the complex treatment of children with post-resection mandibular defects].

Abstract

The aim of the study: To develop and implement a comprehensive algorithm for the rehabilitation of patients after partial resection of the mandible using a titanium «growing» endoprosthesis.

Material and methods: The study included 16 patients aged 2 to 7 years, with benign (6 cases) and malignant (10 cases) tumors of the mandible. The patients were divided into 2 groups depending on the time of fixation of the endoprosthesis. Group 1 included patients with simultaneous installation of a prosthesis (7 people). Group 2 included patients with delayed installation of an endoprosthesis (9 people). For the reconstruction of the mandible, «growing» titanium endoprostheses made of Ti6Al4V alloy of various designs were used. Removable orthodontic devices of mechanical and functional type of action, standard elastic mouthguards were used in the process of dental treatment.

Results: A comprehensive algorithm has been developed for the rehabilitation of children after partial resection of the mandible, depending on the time of fixation of the prosthesis and the volume of surgical intervention.

Conclusion: The developed algorithm of complex rehabilitation using a «growing» endoprosthesis and dental support at the pre and postoperative stages allows to reduce the volume of secondary deformation of facial structures and dentition.
