Abstract:
Abstract OBJECTIVE: Vascular lesions of the anterior cranial fossa can receive significant blood supply from the anterior ethmoidal artery. Embolization of this blood supply exposes the parent vessel, the ophthalmic artery, to possible embolic complications, which can lead to loss of vision. A study of the microsurgical anatomy can help delineate the course of the anterior ethmoidal artery and find the best points for proximal control of the blood supply to these lesions. Clinical cases are presented to illustrate how lesions with prominent anterior ethmoidal artery feeders are best approached through fronto-orbital single-flap craniotomies. METHODS: Eight cadaveric dissections to demonstrate the microsurgical anatomy of the anterior ethmoidal artery were performed to study the relevant anatomy. Two clinical cases are presented that demonstrate clinical application of this anatomy through fronto-orbital single-flap craniotomies. RESULTS: Eight arteries were studied in four cadaveric heads. The dissections show the course of the anterior ethmoidal artery from the ophthalmic artery in the orbit, through the anterior ethmoidal foramen into the ethmoid air cells, to the cribriform plate, where it turns superiorly to become the anterior falx artery. The first surgical case is of a giant tuberculum sellae meningioma that was resected with coagulation and division of the anterior ethmoidal arteries at the anterior ethmoidal foramina at the laminae papyraceae of both medial orbital walls. The second surgical case is of a large deep right frontal arteriovenous malformation that was resected with coagulation and division of the anterior ethmoidal artery at the anterior ethmoidal foramen of the lamina papyracea of the right medial orbital wall. CONCLUSION: The cadaveric dissections and our surgical experience show that the anterior ethmoidal artery has three important sites for surgical access: 1) the anterior ethmoidal foramen at the lamina papyracea of the medial orbital wall; 2) the anterior ethmoid canal at the lateral ethmoid wall; and 3) extradurally, at the cribriform plate. These three sites are best accessed through a fronto-orbital single-flap craniotomy, which can be unilateral or bilateral, depending on the pathological findings. The described orbital-cranial approach in this article is not being advocated to replace the standard pterional and frontal approaches; rather, we suggest it as an option in these complex cases that require early proximal control of the anterior ethmoidal artery feeders.

Abstract:
Because of its special anatomic features the roof of the anterior ethmoid is a preferred area for frontobasal fractures as well as an area of hazard during ethmoid surgery. As clinical experience proves, the most critical area for lesions to occur is in the vicinity of the anterior ethmoidal artery, especially where it leaves the dome of the ethmoid medially to reach the ethmoidal sulcus in the olfactory fossa. Complete ethmoidal specimens were investigated by means of histologic serial sections in the frontal plane. Forty anterior ethmoidal arteries were anatomically prepared. Special features of their topography including connection with the dura, fixation of the dura to the bone of the skull base, and the variations of the thickness of the surrounding bony wall were studied with regard to their surgical relevance. Of utmost importance is the fact that the bone in the vicinity of the ethmoidal sulcus is up to 10 times thinner than the neighboring roof of the ethmoid sinus. Coronal CT scans demonstrating this most critical point with all its many possible variations are found to be invaluable for the preoperative planning of endoscopic or other ethmoid surgery.

Abstract:
Objective: The aim of this study is to investigate the anatomy of the posterior and middle ethmoidal arteries from the viewpoint of an endoscopic sinus surgeon. Methods: Based on 100 computed tomography images, the anatomical position of the posterior ethmoidal artery in relation to the posterior ethmoid cells was classified into five types. The presence of the posterior and middle ethmoidal arteries, their distance from the skull base, and their length exposed in the ethmoid cells were measured. The association of patients’ age and sex, presence of the middle ethmoidal artery, and anatomical type of the posterior ethmoidal artery with the posterior ethmoidal artery distance from the ethmoid roof was analyzed. Results: The posterior ethmoidal artery’s position, relative to the ethmoid cell walls, was most often near the first wall, anterior to the optic canal (92.5%). The posterior ethmoidal artery’s distance from the skull base ranged from 0 to 6.4 mm (mean: 1.2 mm). Older age, longer length of the posterior ethmoidal artery exposed in the ethmoid cells, and absence of the middle ethmoidal artery were positively associated with a longer posterior ethmoidal artery distance from the skull base. Conclusion: Attention should be paid to the posterior and middle ethmoidal arteries.

Abstract:
AbstractAim:This study investigated the extent to which the anterior ethmoidal artery and anterior ethmoidal foramen could be reliably identified on routine coronal sinus computed tomography scans. Where they could be identified, the relationship of these structures with the vertical height of the skull base, and their distance from an anterior landmark, were measured.Methods:Fifty consecutive coronal sinus computed tomography scans were viewed independently by two observers. Scans were reviewed when the observers' opinions differed.Results:Inter-observer concordance was high. The anterior ethmoidal foramen was visualised in 95 per cent of cases bilaterally and in the remaining 5 per cent unilaterally. The anterior ethmoidal artery was visualised in 33 per cent of scans. The anterior ethmoidal foramen was at skull base level in 72 per cent of sides studied, and below it in the remainder. The distance from the lacrimal crest to the anterior ethmoidal foramen was 22.4 mm (mean; standard deviation 3.7).Conclusion:The anterior ethmoidal foramen is a reliable landmark on coronal computed tomography scans of the paranasal sinuses. From this, the position of the anterior ethmoidal artery can be inferred.

Abstract:
A total of 53 anatomical specimens of the posterior ethmoid and the adjacent anterior sphenoid sinus wall were examined in reference to the operative guidelines for endonasal sphenoidotomy. Six anatomical points of measurement were defined for clinical orientation, and both the absolute and the relative widths of each third (i.e. of each of three vertical sections) of the pars nasalis and the pars ethmoidalis of the anterior sphenoid sinus wall determined. The choana proved to be the most valuable regional anatomic landmark. In 43 cases (41%), a pervading ethmoidal cell was found, extending superiorly and medically all the way up to the nasal septum. In contrast with certain guidelines reported in the literature, 18% of the specimen (sides) showed a wider pars nasalis in the vertical middle third of the anterior sphenoid sinus wall as compared to the adjacent pars ethmoidalis. The thickness of the bone in the anterior wall was similar in both areas. The present measurements support Wigand's recommendation (1990) that the anterior sphenoid sinus wall be perforated paramedially, 10 mm superiorly to the choana.

Abstract:
Objective To determine whether using image guidance technology with 3-dimensional image segmentation increases the endoscopic surgeon’s accuracy, efficiency, and confidence in identifying the anterior ethmoidal artery. Methods This is a cross-sectional study of attending physicians and residents at an academic medical center. Because identification of the anterior ethmoidal artery during image-guided surgery can be challenging, we studied the effect of anterior ethmoidal artery image segmentation (ie, partitioning and coloring) on surgeon test performance. A computerized test was administered to 16 surgeons who were asked to identify the anterior ethmoidal artery on multiplanar computed tomographic images and to answer multiple-choice questions. Half the questions showed segmented images of the anterior ethmoidal artery, and half showed images without segmentation. Efficiency and accuracy of identification and subjective surgeon confidence were determined for each question. Descriptive statistics were used to compare test performance for identification of the anterior ethmoidal artery on images with or without segmentation. Results Percentage of correct answers ( P < .001), efficiency ( P < .001), and confidence ( P < .001) in identification of the anterior ethmoidal artery were significantly better with segmented computed tomographic images. Discussion We demonstrated that use of segmented images improves surgeons’ accuracy, confidence, and efficiency for identification of the anterior ethmoidal artery. Implications for Practice We describe how segmentation can allow surgeons to improve the surgical course by increasing their accuracy, confidence, and efficiency in identifying the anterior ethmoidal artery.

Abstract:
AbstractWhilst it is generally accepted that the standard management for anterior or benign epistaxis is either cautery or anterior nasal packing, that of posterior or intractable epistaxis remains controversial. Various modalities of treatment, ranging from posterior nasal packing to arterial ligation and embolization, have been advocated but none have been unanimously accepted as the treatment of choice.The purpose of this paper was to determine the efficacy of internal maxillary arterial ligation versus combined internal maxillary arterial ligation and anterior ethmoid arterial coagulation in intractable epistaxis.Over a six year period, from 1985 to 1990,454 patients were admitted and treated for epistaxis. Forty-seven patients were diagnosed as having intractable epistaxis on the basis that the epistaxis failed to settle on anterior nasal packing. They were moved to the next step in management, which was combined anterior and posterior nasal packing. There were 30 failures, one was found to have choriocarcinoma of the maxilla, and was treated wtih cytotoxics, and the other 29 were moved to the next step, which was arterial ligation. Fifteen patients had internal maxillary arterial ligation, and 14 combined internal maxillary arterial ligation and anterior ethmoidal arterial coagulation.Large windows were created in both the anterior and posterior walls of the maxillary sinuses and all identifiable branches of the internal maxillary artery were dissected out carefully and two medium size ligating clips were placed over the main trunk, the sphenopalatine and the descending palatine branches. Single clips were placed on all other identifiable branches. Coagulation of the anterior ethmoidal artery was performed with a bipolar cautery. There were three (20 per cent) failures in the internal maxillary arterial ligation group and none in the combined internal maxillary arterial ligation and anterior ethmoidal arterial coagulation group. Furthermore, the three failures were successfully treated with anterior ethmoidal arterial coagulation. The conclusion is that combined internal maxillary and anterior ethmoidal arterial occlusion is the treatment of choice in intractable epistaxis.

Abstract:
Rhinosinusitis is inflammation of the nasal passages and paranasal sinuses, commonly caused by allergies or viral infection. Sinusitis occurs after the development of rhinitis or inflammation of the nasal passages. Rhinitis is most commonly caused by allergens, but it also can be to the result of an infectious or autoimmune process. For rhinitis to progress to rhinosinusitis, there must be obstruction within the ostiomeatal complex, which is the draining center for the maxillary, anterior ethmoid, and frontal sinuses. History and physical exam are more specific than imaging for diagnosis. Complications arising from sinusitis can cause extensive morbidity if not recognized early. The most common complication is periorbital cellulitis arising from ethmoidal sinusitis. Evaluate for severe complications in immunocompromised patients. Adjunctive therapies to relieve nasal obstruction include medications that decrease mucosal edema as well as increase clearance of congestion. Consider avoiding antibiotics if symptoms are of short duration and are consistent with viral sinusitis.

Abstract:
Abstract: Anterior cranial fossa (ethmoidal) dural arteriovenous fistulas are an important subtype of cranial dural arteriovenous fistulas. These fistulas transit the skull base between the ethmoidal artery feeding branch and the anterior inferior frontal lobe. They are most often considered high risk fistulas. Because of their location and almost exclusively cortical venous drainage, they often present with hemorrhage. Surgical clipping and resection is the mainstay of treatment, with a high rate of effectiveness and a low rate of complications. However, in certain cases, transarterial and transvenous embolization have emerged as important management alternatives. This chapter discusses the diagnosis and management of ethmoidal dural arteriovenous fistulas.
