A completely horizontally impacted upper third molar was revealed after routine
dissection of a 62-year-old human cadaver of a Caucasian male. The molar was
penetrating into the maxillary sinus and there was antral dehiscence of its bony
alveolus. The bony alveolus was immediately in front of the greater palatine
canal contents, and the bottom of the alveolus was dehiscent towards the greater
palatine foramen. Within the greater palatine canal and foramen the greater
palatine artery was duplicated and the nerve was found. Such antral relations of
an impacted upper third molar predispose to oroantral communications if
extraction is performed, while the close neurovascular relations represent a risk
factor for postextractional haemorrhage and neurosensory disturbances and must be
borne in mind when deciding on or performing the extraction.
