BACKGROUND: Nowadays the problem of orbital trauma remains extremely relevant. Combined damage of several anatomical structures, globe injury, various clinical manifestations, the necessity of optimal surgical treatment require high-quality, timely diagnostics. Considering the current development of diagnostic equipment, postprocessing of CT data acquires the key role in order to obtain objective diagnostic information in patients with orbital trauma.
AIM: Evaluation of the effectiveness of the developed methods for CT data assessing in patients with orbital trauma.
MATERIALS AND METHODS: From 2016 to 2021 a total of 107 patients (100%) with orbital injuries were examined in Sechenov University clinics. All patients were distributed depending on the injury occurrence time: 50 patients (47%) — in acute and subacute periods, 30 patients (28%) — in the period of formation of post-traumatic deformities, 27 patients (25%) — in the period of formed post-traumatic deformities. All patients (n = 107; 100%) underwent CT data analysis according to the developed protocol: analysis of bone and soft tissue trauma using a specialized algorithm, assessment of orbital volumes, evaluation of defects in the inferior orbital wall, examination of the globe position and of changes in the density of the orbital soft tissues.
RESULTS: In the preoperative period the developed algorithm for orbital volumes measuring additionally revealed a post-traumatic increase in orbital volume in 21 patients (19%). The technique for the globe position assessing additionally revealed the risk of enophthalmos in 9 patients (8.1%), and in 1 case (0.9%) the suspicion of globe displacement was not confirmed. The defects of the inferior orbital wall were classified into small (n = 18; 17%), medium (n = 31; 29%) and large/total (n = 38; 35% and n = 20; 19%, respectively). In 88 patients (82%), the ratio of the defect to the entire inferior orbital wall was more than 6.65%, in 19 patients (18%) — less than 6.65%. Changes in the density of the orbital soft tissues were as follows: soft tissue edema — n = 60 (56%), soft tissue atrophy — n = 28 (27%), hematoma of the orbital soft tissues — n = 10 (9%), density was not changed — n = 9 (8%). In the postoperative period, the developed methods for CT data processing revealed incomplete restoration of the orbital volume in 31 cases (29%), incomplete coverage of the inferior orbital wall defect in 38 cases (35%), globe displacement in 14 cases (13%), which was not determined by the standard CT data assessment without the specialized technique. In 7 cases (6%), a suspicion of an increase in the orbital volume was not confirmed by the developed methodology.
CONCLUSION: The developed methods for measuring orbit volumes, assessing defects in the lower orbital wall, the globe position, and the condition of the orbital soft tissues provide statistically reliable additional diagnostic information about the patient’s condition and personalized approach for preoperative planning for each patient.
