Objective To evaluate the clinic value the technique of Cuboid stereotactic catheter (TCSC) in the treatment of small-volume traumatic extradural hematoma in non-functional areas.Methods We performed a retrospectively analysis of 65 patients with small-volume(15-30 mL) traumatic extradural hematoma in non-functional areas. All of which were divided into two groups according to the different treatments. 35 cases treated with drugs were control group, while the rest of 30 cases with both drugs and TSCS were treatment group. The complication incidence and hematoma clearance rate in hospitalization time, recurrence rate of headache, anxiety,hematoma clearance rate at 3 and 6 months follow-up were compared between the two groups.Results The hematoma clearance rate in control group and treatment group were 25.7% and 66.7%,respectively. (P=0.001), while the complication rate was no obvious differences. The recurrence rate of headache, anxiety and hematoma clearance rate at 3 months follow-up were different between the two groups. These conditions were not happened at 6 months follow-up.Conclusion TCSC may eliminate the hematoma within a short hospitalization time by avoiding extra complication coincidence, improve the short-term life quality of patients such as relief the symptoms like headache and anxiety in the patients with small-volume(15~30 mL) traumatic extradural hematoma in non-functional areas. Above of results indicates the impact of this technique on neurosurgical practice.
