Abstract: Objective To analyze the therapeutic effect and prognosis according to a new CT classification of traumatic posterior occipital epidural hematomas (POEH). Methods We classified the CT presentation of 104 patients with POEH by sinus transverses: type Ⅰ hematomas were defined as up-sinus transverses; type Ⅱ hematomas were defined as sub-sinus transverses and type Ⅲ hematomas were defined as straddling sinus transverses. The above types were divided into unilateral or bilateral subtypes. Bone flap craniotomy through a median posterior approach was performed in patients with unilateral hematoma adjacent to the midline. Bone flap craniotomy through a median suboccipital approach was adopted for patients with bilateral middle occipital hematoma. Results Type Ⅰ enjoyed mild symptoms, good curative effect and low mortality rate (7%). Type Ⅱ and Ⅲ had serious symptoms and high mortality rate (13.3%, 16.6%, respectively). Conclusion The classification of the CT presentation of POEH is helpful in confirming the diagnosis, drawing up the scheme of treatment and judging the prognosis.
