Double accessory mental foramina: report of an anatomical variant

The presence of accessory mental foramina ( AMF ) in mandible is a rare anatomical variation. Single accessory mental foramen is reported in a few studies, but double AMF ( DAMF ) is very uncommon. We present an unusual case of DAMF , with accessory nerves, which were identified during maxillofacial oncology surgery. The nerves were protected by a modified mandibulotomy. It is essential that surgeons to be aware of the possibility of AMF existence and are prepared to take appropriate actions to avoid iatrogenic nerve injury.
