Posterior Superior Alveolar Artery Mnemonic [ NEVER FORGET AGAIN ]

Mnemonic :   POSTERIOR

P – “Pterygopalatine Fossa”: The PSAA arises from the pterygopalatine fossa.

O – “Orbital Branches”: The PSAA gives off orbital branches that supply blood to the posterior superior part of the maxilla.

S – “Supplies Maxillary Molars”: It primarily supplies the maxillary molars, especially the second and third molars.

T – “Transverse Maxillary Foramen”: The PSAA enters the maxilla through the transverse maxillary foramen.

E – “Ends in the Maxilla”: The PSAA terminates within the maxilla, providing vital blood supply to the maxillary teeth and adjacent structures.

R – “Relevant in Dentistry”: Knowledge of the PSAA is crucial in dentistry for procedures involving maxillary molars, as any damage to this artery can lead to significant bleeding and complications.

I – “Inferior Alveolar Artery”: Distinguishing from the inferior alveolar artery, the PSAA supplies the upper posterior teeth, while the inferior alveolar artery supplies the lower posterior teeth.

O – “Originates from Maxillary Artery”: The PSAA originates as a branch of the maxillary artery, a major branch of the external carotid artery.

R – “Root Canal Procedures”: Dentists must be cautious when performing root canal procedures on maxillary molars to avoid damaging the PSAA, which could result in hemorrhage.
