Study on application of small bone window craniotomy in treatment of hypertensive cerebral hemorrhage

【Objective】To investigate the operative techniques and curative effect of small bone window craniotomy in the treatment of hypertensive cerebral hemorrhage (HCH). 【Methods】According to the different operative types, 106 patients with hypertensive cerebral hemorrhage (HCH) were randomly divided into two groups: 56 cases were in small bone window craniotomy group and 50 cases were in big bone flap craniotomy group. The indexes including consciousness recovery time, neurologic impairment score, total effective rate and mortality were comparatively analyzed.【Results】The consciousness recovery time in small bone window craniotomy group was shorter than that in big bone flap craniotomy group (t =3.16, P 0.01). At postoperative 1 month, the improved variance of neurologic impairment score in small bone window craniotomy group excelled that in big bone flap craniotomy group (t= 5.75, P 0.05). The total effective rate in small bone window craniotomy group was higher than that in big bone flap craniotomy group while the mortality in the former was lower than that in the latter (χ2=4.80, P 0.05).【Conclusions】Small bone window craniotomy is an effective approach for hypertensive cerebral hemorrhage. It has advantages such as simple operative techniques, slight trauma, few complications and profitting neurofunctional recovery.
