TL;DR: This study aims to determine objective data to improve the methods of identification of the anterior ethmoidal artery during endoscopic dissection.
Abstract: Objectives To determine objective data to improve the methods of identification of the anterior ethmoidal artery during endoscopic dissection.
Study Design Cadaveric dissection of adult human heads.
Methods A 0°, 4-mm rigid endoscope was used to guide uncinectomy and frontoethmoidectomy. The location of the anterior ethmoidal artery was first determined visually and then confirmed by passing a needle through the anterior ethmoidal foramen from the orbit into the nose in all cases. The distances were endoscopically measured using a simple ruler between two nasal landmarks and the anterior ethmoidal artery.
Results Fifty-six nasal fossae in 28 cadavers were dissected endoscopically. The median distance between the artery and the “axilla” formed by the anterior attachment of the middle turbinate to the lateral nasal wall was 20 mm (range, 17–25 mm), irrespective of the side. The measurement differed by less than 2 mm between the sides in the same individual. The median distance between the artery and the “axilla” formed by the medial and lateral crura of the lower lateral cartilage (superomedial edge of the nostril) was 62 mm (range, 55–75 mm) for both sides. The artery was found to be in direct alignment with the two “axillae” formed by the middle turbinate and the nostril edge.
Conclusions The distance between the ethmoidal artery and the axilla of the middle turbinate showed the least intraindividual and interindividual variations. The tip of the endoscope (or the ruler) points directly at the anterior ethmoidal artery in the fovea ethmoidalis when its edge is aligned with the two nasal landmarks. These simple guidelines can aid the identification of the artery in endoscopic frontoethmoidectomy.

TL;DR: The angiographic appearance in both cases is quite uniform and resembles the findings in 12 cases previously reported, and a drainage vein always shows aneurysmal dilatation of its proximal portion.
Abstract: Two cases of dural arteriovenous malformation at the base of the anterior fossa are reported. The angiographic appearance in both cases is quite uniform and resembles the findings in 12 cases previously reported. Feeders are anterior and/or posterior ethmoidal arteries and the external carotid system also contributes. A drainage vein always shows aneurysmal dilatation of its proximal portion. CT findings are also mentioned and radiological literature reviewed.

TL;DR: The pathway of nerves containing acetylcholinesterase to the major cerebral arteries was investigated in the rat and many thick nerve bundles were found in the periadventitial layers in association with these vessels.
Abstract: The pathway of nerves containing acetylcholinesterase (AChE) to the major cerebral arteries was investigated in the rat. In this species, the internal ethmoidal artery (IEA) arises from the anterior cerebral artery (ACA) and anastomoses with the external ethmoidal artery (EEA), forming the ethmoidal rete on the cribriform plate. The ethmoidal nerve (EN) and EEA enter the cranial cavity through the ethmoidal foramen. Densely distributed adventitial nerve plexi were present around the IEA, ethmoidal rete, and EEA. Many thick nerve bundles were found in the periadventitial layers in association with these vessels. Around the EN, just before it enters the ethmoid foramen, intensely staining nerve bundles were present that entered the cranial cavity with the EN.
After unilateral. section of the EN and EEA, a marked decrease of the nerve fibers was observed around the arteries of the anterior part of the circle of Willis on the operated side, whereas the basilar artery (BA) showed a moderate decrease in the AChE activity. After bilateral section of the EN and EEA, nerves disappeared from around all the major cerebral vessels including the BA. Section of the EEA alone did not produce any visible change of the cerebral perivascular innervation.
The present study suggests that (1) AChE-containing nerves on the cerebral arteries arise from the AChE-positive nerve bundles, which enter the cranial cavity with the EN through the ethmoid foramen; (2) The anterior part of the circle of Willis is innervated unilaterally by the AChE-positive nerve bundles from the ethmoidal foramen, whereas the BA receives bilateral innervation.

TL;DR: ELSPA and ELSPEA are effective, well-tolerated, reliable procedures if performed by an experienced surgeon and can be appropriate methods to treat severe recurrent epistaxis refractory to repeated nasal packing.
Abstract: Objectives: We describe the surgical treatment of severe epistaxis and evaluate the recurrence of bleeding in a nonrandomized retrospective trial. Methods: We performed a retrospective study comparing bilateral endoscopic ligation of the sphenopalatine artery alone (ELSPA) and bilateral endoscopic ligation of the sphenopalatine artery with concomitant bilateral external ligation of the anterior ethmoidal artery (ELSPEA) in the management of persistent epistaxis. Clinical and hematologic information, preoperative and surgical care, and short- and long-term outcomes were analyzed. The main outcome measure was recurrence of epistaxis in the short- and long-term follow-up periods. Results: Forty-five patients were enrolled in the study. There were 20 patients in group A (ELSPA) and 25 in group B (ELSPEA). Three patients in group A and no patients in group B had long-term (more than 2 weeks after surgery) re-bleeding. The difference between the two groups was not statistically significant (p > 0.05). Conclusions: We conclude that ELSPA and ELSPEA are effective, well-tolerated, reliable procedures if performed by an experienced surgeon. Their failure can be explained by anatomic lateral nasal wall variations and perioperative technical difficulties. They can be appropriate methods to treat severe recurrent epistaxis refractory to repeated nasal packing.
