“…In majority of the cases (72%), the infraorbital foramen was situated in the narrow range of 55.1to 65 mm distance from ANS (Table 2). 5 worked on bony skull, whereas we studied on cadaveric specimens, which is more close to real-life situations. Another posteriorly situated reference that can assist in localization of foramen is horizontal lamina of IT.…”

“…Anterior nasal spine (ANS), horizontal plate of palatine bone, and bony crista ethmoidalis are few such examples. 1,4,5 Large variations with regard to the measurements of distance of SPF from the landmarks have been reported in the literature. 5 The current study was planned to provide a detailed account of the variations of the SPF and to determine the location of SPF by taking measurements from anteriorly and posteriorly located intranasal landmarks relevant to endoscopic localization of SPA and the best angle for endoscope elevation to reach the SPF.…”

Introduction:In patients with posterior epistaxis, generally the source of bleeding is branches of sphenopalatine artery (SPA), which enter the nasal cavity through the sphenopalatine foramen (SPF). Cases of intractable massive bleeding may require endonasal endoscopic occlusion of these vessels. Materials and methods:A total of 32 hemisections of formalinfixed cadaveric heads were used. The anatomic variations of SPF, its distance from anatomical landmarks, and angle of elevation of endoscope were studied so as to facilitate accurate localization of the foramen and endoscopic arterial ligation. Results:The SPF was generally single; however, multiple exits in the form of accessory foramina were found in 36.75% hemisections. The transition of superior and middle meatuses was the most common location of SPF, followed by the superior meatus, and middle meatus was the least common site. The accessory foramina were commonly present in the superior meatus. Ethmoid crest was distinctly visible in all but two cases. In majority of the cases, the SPF was located within a range of 55 to 65 mm from the anterior nasal spine (ANS); 60 to 70 mm from piriform aperture, 50 to 60 mm from limen nasi, 20.1 to 25 mm vertically above the floor of nasal cavity, and 8 to 15 mm from the inferior turbinate (IT). The angulation of SPF from the floor of nasal cavity was 20 to 30°. Conclusion:Exploration of lateral nasal wall (LNW) up to middle meatus would minimize the risk of missing any arterial branch, and the data of distance from the anatomical references would assist in more precise localization of SPF during endoscopic ligation or cauterization of the branches of the SPA.

Severe epistaxis management remains a challenge to otolaryngologists. Despite the large choice of treatment strategies to control epistaxis, the method of regional haemostasis via edoscopic arterial ligation has become frequently used. Arterial supply occlusion is usually performed by electrocautery or application of titanium clips. After placement of titanium clips, they will remain in place forever and could surprisingly be rediscovered later on CT-scan. Most of otolaryngologists are familiar with this method and are able to identify these clips, however, it could be more difficult for radiologists and other practitioners. In order to draw the attention of other specialists to the existence of this method and to help them correctly interpret such CT-scans, the authors present an example of a case that troubled radiologists. In addition, the authors also discussed the vascular supply of the nasal fossa and methods of severe epistaxis management.
