[Laser information technologies in oncosurgery].

The introduction of laser information technologies to medical practice has improved the results of reconstructive and plastic operations in oncology thanks to a possibility to plan the surgery beforehand. Sixty-eight patients were operated on at Gertsen Moscow Research Oncology Institute between 2001 and 2006; 99 stereolithographic models were used to plan different stages of the surgical intervention. The tasks fulfilled with an individual stereolithographic model, may be relatively divided into three groups: 1) planning the resection stage; 2) planning the reconstructive surgery; 3) assessing the necessity to correct the complex autograft after the reconstructive surgery. The use of laser stereolithographic modelling in surgical treatment of patients with locally advanced malignancies made it possible to complete the reconstructive operation successfully in 98.4% of the patients, and rehabilitate functionally 88.6% of the patients.

[Perspective of skull reparative surgery using three-dimensional computed tomography and stereolithography]. / Perspektivy rekonstruktivnoi khirurgii cherepa s ispol'zovaniem trekhmernoi komp'iuternoi tomografii i stereolitografii.

The review presents the stages of the development and use of virtual three-dimensional CT images. A possibility to get a 3D-based real skull model and an implant for reconstruction using a 3D-prototype technique (stereolithography) is a new step to the development of reconstructive surgery.

[Potentialities of spiral computed tomography in the diagnosis and treatment of traumatic injuries of the midface]. / Vozmozhnosti spiral'noi komp'iuternoi tomografii v diagnostike i lechenii travmaticheskikh povrezhdenii srednei zony litsa.

The paper summarizes the results of examination of 169 patients referred to the surgeon in the period from 1 till 47 days after medial facial (MF) trauma by using spiral computed tomography (SCT) and the method of laser stereolitography (LSLG). The actual aspects of diagnosis and treatment are marked; the methods for the analysis of injuries of soft tissue structures and adjacent areas while orbit trauma are developed together with the methods for determination of degree of enophthalmos. Also discussed are the possibilities of SCT and LSLG in visualization of MF injuries and planning patient treatment.

[The possibility of using a laser stereolithography method in forensic medicine]. / O vozmozhnosti primeneniia metoda lazernoi stereolitografii v sudebnoi meditsine.

The data of computer-aided tomography are proposed to be used in forensic medical diagnostic and identification studies. The technology of making hard copies of objects by laser stereolithography on the basis of tomography data is described.
