Abstract

Background:  The mental foramen is usually single, if there are more than one, the additional foramen is termed accessory foramen. The prevalence of accessory mental foramen is 1.4-10 %. Although this anatomical variation is rare, it should be kept in mind that an AMF may exist. Even so, in order to avoid neurovascular complications, particular attention should be paid to the possible occurrence of one or more AMF during surgical procedures involving the mandible. Careful surgical dissection should be performed in the region so that the presence of AMF can be detected and the occurrence of a neurosensory disturbance or haemorrhage can be avoided. Trigeminal neuralgia was diagnosed. On the basis of diagnostic test results, peripheral neurectomy of mental nerve was planned. Failure to do neurectomy of mental nerve branch in the reported case, coming out from AMF, would have resulted in recurrence of pain and eventually failure of the procedure.
