Establishing a Multidisciplinary Cavernous Carotid Injury Simulation to Train Neurosurgical, Otolaryngology, and Anesthesia Residents.

Carotid artery injuries are serious complications of endoscopic endonasal surgery. As these occur rarely, simulation training offers an avenue for technique and algorithm development in resident learners. This study develops a realistic cadaveric model for the training of crisis resource management in the setting of cavernous carotid artery injury.

Development of a Cadaveric Multiport Model of Posterior Circulation Aneurysm Clipping for Neurosurgery and Otolaryngology Residents.

Posterior circulation aneurysms are difficult to treat with the current methods of coiling and clipping. To address limitations in training, we developed a cadaveric model to train learners on endoscopic clipping of posterior circulation aneurysms. An endoscopic transclival approach (ETA) and a transorbital precaruncular approach (TOPA) to successfully access and clip aneurysms of the posterior circulation are described.

Paramedian Forehead Flap for Repair of Refractory High-Flow Anterior Skull Base CSF Leak.

The paramedian forehead flap (PMFF) has been well described for nasal reconstruction. However, it has never been reported for use in the repair of high flow anterior skull base cerebrospinal fluid (CSF) leaks. The patient was a 55 year-old African American male cocaine abuser who initially presented with a high flow anterior skull base CSF leak, extensive pneumocephalus, and intra-cerebral and intra-ventricular abscesses with an oro-nasal-cerebral fistula.
