Abstract
Objective:
Epidural hematoma of posterior fossa is less common than epidural hematoma of supratentorial area, and there are not many articles about epidural hematoma of posterior fossa. This study investigated patients who underwent surgery of epidural hematoma of posterior fossa, and the relation between the clinical manifestation and postoperative outcome.
Methods:
A retrospective analysis performed of 27 patients who underwent operation for acute traumatic epidural hematoma of posterior fossa from January 2004 to December 2011. Analyzed factors were gender, age, Glasgow Coma Scale (GCS) measured upon presentation to the hospital, preoperative GCS score, cause of trauma, time elapsed from the accident to the presentation to the hospital, time elapsed from the presentation to the hospital to the surgery, radiographic findings (brain CT findings), and Glasgow Outcome Scale (GOS).
Results:
Two patients (7.4%) had GCS score on admission of 3-8, 11 (29.6%) had 9-12, and 17 (66.7%) had 13-15. In 1 (3.7%) patient, GCS score changed from 13 to 10, and preoperative GCS score was significantly correlated with GOS score (p<0.05). Mean thickness of hematoma was 19.3±7.5 mm, and was significantly correlated with GOS score (p< 0.05). GOS score was 4-5 in 24 patients (88.9%), 3 (severe disability) in 1 patient (3.7%), and 1 (death) in 2 patients (7.4%).
