[Surgical removal of a lower semimpacted wisdom tooth displaced in the pterygomandibular space]

In the case which is reported in this paper there was a dislodgement of a semimpacted lower left third molar (38) into the pterygomandibular space, from a removal attempt, without the usual fracture of the lingual plate of the alveolar bone. There is an anatomical description of the pterygomandibular space, the operative complications during removal of impacted lower teeth and more specific the displacement of teeth or roots into adjacent soft tissues, ways of prevention and treatment of such complications. Finally, we describe the technique which we followed to extract the dislocated lower molar in our case.
