Background: The frontal lobe is the second most common location for brain abscess after the temporal lobe. Since the advent of computed tomography and magnetic resonance imaging scanning, diagnosis has become easier, but the prognosis of brain abscess is still poor. Treatment is based on antimicrobial therapy and neurosurgical evacuation, but controversy still remains as to the merits place of each.
Methods: This study describes 2 cases of patients with frontal abscesses treated by endonasal transethmoidal sinus surgery (ESS) and reviews the literature on this topic.
Results: Follow-up revealed no cerebrospinal fluid leak in both patients, complete abscess drainage in one patient, and incomplete drainage in the other.
Conclusions: ESS drainage of frontal abscesses is feasible in intracerebral and epidural abscesses if they have a thick shell and are in contact with the skull base. The procedure is minimally invasive and relatively simple. It allows for rapid microbial identification and an effective drainage.

Over recent decades, global warming has led to sustained glacier mass reduction and the formation of glacier lakes dammed by potentially unstable moraines. When such dams break, devastating Glacial Lake Outburst Floods (GLOFs) can occur in high mountain environments with catastrophic effects on populations and infrastructure. To understand the occurrence of GLOFs in space and time, build frequency-magnitude relationships for disaster risk reduction or identify regional links between GLOF frequency and climate warming, comprehensive databases are critically needed.

BACKGROUND Decompressive craniectomy is a common life-saving intervention in the setting of elevated intracranial pressure. Cranioplasty restores the calvarium and intracranial physiology once swelling recedes. Cranioplasty is often thought of as a low-risk intervention.

Traumatic direct type carotid cavernous fistula (CCF) is an acquired arteriovenous shunt between the carotid artery and the cavernous sinus post severe craniofacial trauma or iatrogenic injury. We reported a 46-year-old woman who had developed a traumatic direct type CCF after severe head trauma with a skull base fracture and brain contusion hemorrhage. The clinical manifestations of the patient included pulsatile exophthalmos, proptosis, bruits, chemosis, and a decline in consciousness.
