Posterior superior alveolar nerve block is most commonly used pterygoid plexus the surgical procedures, extraction or root canal treatment of the maxillary molars with possible exception of mesiobuccal root of maxillary first molar and buccal soft tissues.

The injection of local anesthesia is usually safe but a rare complication of extraoral hematoma formation in the mandibular pterygoid plexus buccal region might occur due to the insertion of the needle to far posteriorly into the pterygoid plexus pterygoid plexus veins, maxillary artery — posterior superior alveolar artery and the facial artery which is esthetically unpleasant to the patient and quite embarrassing for the dentist.

This case report describe the complication of posterior superior alveolar nerve block and its pterygoid plexus. Main article text Introduction The unintentional nicking of the blood vessels artery or vein with needle during the injection of local anesthesia might results in effusion of blood into the extravascular spaces with subsequent hematoma formation.

Puncture of vein by needle may or may not results in the formation of hematoma but perforation of artery subsequently develop hematoma which rapidly increases in size until treatment is instituted due to significantly greater blood pterygoid plexus within the artery.

The size of the hematoma also depends upon the density of the pterygoid plexus surrounding the blood vessel. The posterior superior alveolar PSA nerve block targets the posterior superior nerve in the infratemporal fossa.
