How do you find the sphenopalatine artery?
The location of the sphenopalatine foramen (SPF) is identified within the superior meatus after elevation of a mucoperiosteal flap and identification of the crista ethmoidalis from the posterior aspect of the middle meatus. Opening the maxillary sinus may assist the surgeon if these landmarks are not quickly found.
Why is sphenopalatine artery called artery of epistaxis?
The sphenopalatine artery, formerly known as the nasopalatine artery, is the terminal branch of the maxillary artery that is the main supply to the nasal cavity. It is colloquially know as the artery of epistaxis given its common involvement in cases of nose bleeds.
What is the sphenopalatine artery a branch of?
internal maxillary artery
The sphenopalatine artery is a terminal branch of the internal maxillary artery originating from the external carotid artery system. [4] The SPA is the major blood vessel to the nasal cavity mucosa: supplying the superior, middle, and inferior turbinate; lateral nasal wall; and nasal septum.
What are the branches of maxillary artery?
Five branches, each of which enters a bony foramen:
- deep auricular artery (enters squamotympanic fissure)
- anterior tympanic artery (enters squamotympanic fissure)
- middle meningeal artery (enters foramen spinosum)
- accessory meningeal artery (enters foramen ovale)
- inferior alveolar artery (enters mandibular foramen)
What is a sphenopalatine artery ligation?
Sphenopalatine artery ligation is a commonly employed surgical intervention for control of posterior epistaxis unresponsive to nasal packing.
What is the sphenopalatine foramen?
The sphenopalatine foramen (SPF) represents an opening on the lateral nasal wall that is present at the articulation between the superior aspect of the vertical portion of the palatine bone and the inferior projection of the sphenoid bone.
What is the greater palatine artery branch of?
descending palatine artery
The greater palatine artery is a branch of the descending palatine artery (branch of the 3rd part of the maxillary artery) 4. The blood vessel supplies the hard palate mucosa, gingival tissue, and palatine tonsils 5.
What are the 5 branches of the maxillary artery?
What is endoscopic sphenopalatine artery ligation?
An endoscopic transnasal approach for ligation of the terminal branch of the internal maxillary artery, the sphenopalatine artery, provides an alternative to transantral ligation. We have used endoscopic ligation of the sphenopalatine artery to treat 38 patients requiring surgical therapy for epistaxis.
What is Sphenopalatine fossa?
In human anatomy, the pterygopalatine fossa (sphenopalatine fossa) is a fossa in the skull. A human skull contains two pterygopalatine fossae—one on the left side, and another on the right side. It is the indented area medial to the pterygomaxillary fissure leading into the sphenopalatine foramen.
What traverses the sphenopalatine foramen?
The sphenopalatine foramen connects the nasal cavity and the pterygopalatine fossa, transmitting the nasopalatine nerve, posterior superior nasal nerves, and sphenopalatine artery and vein.
