An anatomico-radiological study of an accessory mandibular foramen on the medial mandibular surface
Folia Morphol 2004;63(4):511-513.
Abstract
Unnamed foramina are known to be present in the mandible. The present research
paper reports the presence of an accessory foramen on the medial surface
of the mandible, highlighting its anatomico-radiological details. Accessory
foramina in the mandible have been known to transmit branches of nerves supplying
the roots of the teeth. Nerve block techniques by local anaesthetics might
fail if any of these nerves or their branches pass through these accessory foramina
and thus escape the nerve block. Dental surgeons performing extractions
should be aware of accessory foramina on the mandible and thus plan anaesthesia
at an appropriate anatomical site. The presence of such foramina might
also be an alternate route for tumour spread following radiation therapy. Precise
knowledge and awareness of such accessory mandibular foramina would
therefore be important for dental surgeons performing nerve block and also for
oncologists in planning radiation therapy.
