| Objective:Reasons for the changes observed three different timing of surgery titanium mesh cranioplasty intracranial blood flow rate before and after surgery, neurological and cognitive function, and to explore neurological and cognitive function and optimal timing of surgical repair. Methods:Select skull skull defect repair 78 patients, according to the skull repair surgery were divided into time (1 to 3 months after surgery) 20 cases of group A, B group (surgery after 3 to 6 months) 31 cases, C group (after surgery six months or more) in 27 cases. Respectively, after 3 days before surgery in March of intracranial blood flow velocity in patients with neurological and cognitive function evaluation of intracranial blood flow rate detection using transcranial color Doppler ultrasound (TCD) technology; neurological evaluated using the NIHSS (National Institutes of Health stroke Scale), cognitive function evaluation using MMSE (concise intelligence scale) were observed in all groups cranioplasty intracranial blood flow rate, neurological and cognitive function before and after surgery changes. Results: 78 cases were treated with three-dimensional effect repair titanium mesh cranioplasty satisfaction, fewer complications, the overall complication rate difference between the groups was not statistically significant (P>0.05). Cranioplasty surgery, neurological and cognitive patients in each group had significantly improved compared (P<0.05) before the function and operation; before surgical repair of blood flow rate and the contralateral side was significantly lower compared to the rate of blood flow on both sides of the asymmetry (P<0.05), after the patch fixes the rate of blood flow compared with the preoperative side has improved significantly (P<0.05); preoperative blood flow asymmetry is improved. The extent of the surgery side increased blood flow rate difference was statistically significant (P<0.05). A and B group difference was statistically significant (P<0.05). A comparison with C group was significantly (P<0.05). Group B and C was statistically significant difference (P<0.05). Conclusion:Early dimensional titanium mesh cranioplasty more widely and strongly enhance the level of cerebral blood flow and improve the neurological and cognitive function, it did not increase the incidence of complications, so the premise under strict indications skull repair surgery as soon as possible. |
