Abstract.
An increase in the volume of the orbit with its fractures is considered to be the main cause of the development of painful conditions such as enophthalmos, hypophthalmos, diplopia and others. Therefore it is proposed to use volumetric parameters changes of the orbit to assess the effectiveness of reconstruction of its bone walls. The research presents an assessment of the orbit reconstruction effectiveness based on volumetric indices obtained using the developed software for automatic processing of orbital MSCT output files before and after surgery using the 3D modeling and prototyping method. The study included 205 patients with orbital injuries who had been operated with the use of an individual orbital implant (172 patients) and 33 patients with the use of standard implants. The use of MSCT with the developed software tool, preoperative planning technology and a prefabricated individual implant ensured complete restoration of the orbital anatomy both in the early post-traumatic period (Vintact orbit 26.4 cm3 – Vreconstructed orbit 26.6 cm3, p1.3=0.47) and in the late period (Vintact orbit 26.5 cm3 – Vreconstructed orbit 26.9 cm3, p1.3=0.16). The use of this technology in patients in the late post-traumatic period allowed, although not completely, to bring the volumes Vreconstructed orbit 27.7 cm3 and Vintact orbit 26.9 cm3 closer together, p1.3<0.001. Restoration of volumetric parameters of the damaged orbit to the parameters of a healthy orbit allowed to eliminate or reduce the severity of enophthalmos in patients of the main group with all types of the orbital fractures, complete elimination of post-traumatic enophthalmos (p<0.001) was diagnosed in 71 (100%) patients with isolated and in 44 (100%) patients with combined fractures.
Keywords: orbit, orbital injuries, enophthalmos, surgical treatment of orbital injuries, orbital implants, computed tomography.
