A bstract — Anatomical dissections and examination of the soft tissues in the region of the buccal sulcus of the maxilla reveal the presence of a bucco‐gingival branch of the posterior superior alveolar artery which approaches the infra‐orbital surface of the maxilla. In some specimens this was found to anastomose with the infraorbital artery. It is suggested that this branch is the major contributor to rapidly forming haematomata which may sometimes occur following injections to obtain anaesthesia of the maxillary teeth. A modification to accepted techniques for local anaesthesia is proposed to avoid or minimize this complication.
