Vertex epidural hematoma with bilateral abducent nerve palsy: case report and literature review

Clinical features and treatment strategies for vertex epidural hematoma: a systematic review and meta-analysis from individual participant data

Vertex epidural hematoma (VEDH) is a rare extradural hematoma and often misdiagnosed because of its variety of clinical symptoms and characteristic location. Determining optimal timing and technique for VEDH surgery is difficult because of its midline location and atypical clinical course. This study aims to understand the clinical manifestations and current treatment strategies for VEDH. We searched the published literature regarding VEDH through PubMed and Google Scholar, and individual patient data (IPD) were obtained from the eligible articles. A systematic review and IPD meta-analysis were conducted. In total, 70 patients' individual participant data were gathered. Most patients were male (87%), and traffic-related accidents were the most common injury mechanism (49%). Approximately half the patients (47%) were neurologically intact with nonspecific symptoms such as headache, dizziness, and vomiting at admission. Motor weakness alone (17%) and symptoms related to cranial nerve dysfunction such as anosmia, blurred vision, or diplopia (10%) were also noted. A surgical approach was initially chosen for 20 patients (28%), but eventually chosen for 20 more (total 40, 57%) during the observation period (average delay to surgery, 5 days). Patients who received surgery showed significantly poorer neurological status and larger hematoma size. Totally, two patients (3%) died, but most patients (94%) had a favorable outcome scoring 5 on the Glasgow Outcome Scale. Although VEDH generally showed favorable outcomes, clinicians must be aware of a high rate of delayed neurological deterioration during the observation period, which can be fatal due to central downward herniation.

Trauma of the midface

Fractures of the midface pose a serious medical problem as for their complexity, frequency and their socio-economic impact. Interdisciplinary approaches and up-to-date diagnostic and surgical techniques provide favorable results in the majority of cases though. Traffic accidents are the leading cause and male adults in their thirties are affected most often. Treatment algorithms for nasal bone fractures, maxillary and zygomatic fractures are widely agreed upon whereas trauma to the frontal sinus and the orbital apex are matter of current debate. Advances in endoscopic surgery and limitations of evidence based gain of knowledge are matters that are focused on in the corresponding chapter. As for the fractures of the frontal sinus a strong tendency towards minimized approaches can be seen. Obliteration and cranialization seem to decrease in numbers. Some critical remarks in terms of high dose methylprednisolone therapy for traumatic optic nerve injury seem to be appropriate. Intraoperative cone beam radiographs and preshaped titanium mesh implants for orbital reconstruction are new techniques and essential aspects in midface traumatology. Fractures of the anterior skull base with cerebrospinal fluid leaks show very promising results in endonasal endoscopic repair.
