ABSTRACT Objective Sphenopalatine ganglion (SPG) block is used for a variety of craniofacial pain syndromes either through the trans-nasal route or via the infrazygomatic approach. Intraoperative imaging can identify the pterygopalatine fossa (PPF) but not the exact position of the SPG. Accurate localization of the PG requires knowledge of the relevant anatomical landmarks. Materials and methods Thirty mid sagittal head and neck cadaveric sections were studied and the morphometric data was te correct SPG localization via trans-nasal roach and infrazygomatic approach. Results The sphenopalatine foramen (SPF) was located at an average distance of 55 mm from the anterior nasal spine at a mean angle of 22°. It was at or just superior to the midpoint of a line joining the skull base and the hard palate. The SPG was located 4 mm posterior and 4.7 mm lateral to the SPF at a mean distance of 6.3 mm from the SPF at an inclination of about 50° in both the sagittal and coronal planes. In the infrazygomatic approach, the SPG was between 4.5 and 6.3 cm the skin and an angle of about 7° posterior and inferior. Conclusion These morphometric measurements will be of help to the clinician for accurate electrode or needle placement for SPG block and in avoiding complications related to inaccurate needle placement.

ABSTRACT 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.

Abstract Background A consensus on facial artery (FA) anatomy has not been established due to the discrepancies in previous studies. Objectives The purpose of this study was to assess the branches, course, and location of the FA in Asians utilizing computed tomographic angiography (CTA). Methods The CTA images of 300 FAs from 150 Asian patients were evaluated. According to the termination branch, the FA was classified as follows: type 1, FA terminates superior labial or inferior labial artery; type 2: FA terminates lateral nasal or inferior alar artery; type 3: FA terminates medial canthal artery; type 4: FA is divided into duplex branches with dominant medial canthal artery laterally. The relationship between nasolabial fold and FA was evaluated, and the distances from anatomical landmarks to FA were measured to position the course. Results 70 arteries (23.3%), 163 arteries (54.3%), 49 arteries (16.3%), and the other 18 arteries (6.0%) were classified as type 1, 2, 3 and 4, respectively. 72.3% of FAs were located medially to the nasolabial fold, and only 14.7% of arteries were lateral to the nasolabial fold. The vertical distance between FA and the inner canthus or the midpoint of inferior orbital rim decreased from type 1 to type 4 FA (P < 0.0001). No significant difference was found among the four types of FA in the distances between the mandibular angle (P = 0.1226) or oral commissure (P = 0.1030) and the FA at inferior of mandible. Conclusions The detailed findings of facial artery will provide a valuable reference for filler injection in cosmetic procedures and flap design in reconstructive surgery.
