Intracranial abscess after anterior skull base defect: does pneumocephalus play a role?
Intracranial complications of skull base defects are uncommon; however, they can be devastating when they do occur. Often these complications arise suddenly and without warning. Identifying patients at risk for intracranial abscesses may help with early diagnosis and allow for early interventions. ⋯ Intracranial abscess formation, traumatic skull base defects, and massive pneumocephalus are uncommon entities, which may be associated. It may be prudent to have heightened suspicion for the presence of intracranial abscess formation in patients with massive pneumocephalus secondary to anterior skull base trauma.

Arterial ligation remains a key option in the treatment of persistent epistaxis and clarification of the arterial configuration of the distal maxillary/sphenopalatine artery is important for understanding the rationale behind current surgical treatments. Greater understanding of the arterial anatomy will reduce the risk of technical failures and improve the reliability of surgical interventions for persistent epistaxis and will also be useful for surgeries involving the pterygopalatine fossa. ⋯ The arterial configuration of the maxillary artery in the pterygopalatine fossa can be complex but may be classified into one of three forms. Some configurations may be more liable to lead to difficulties with branch identification during surgical treatment of epistaxis particularly in combination with an inadequate osteotomy. Clinicians should expect to find more than one vessel exiting the sphenopalatine foramen and actively search for these during surgery. Asymmetry in the maxillary/sphenopalatine arteries is not common and contralateral ligations are not indicated.
