A review of the literature, was performed which disclosed no previous clinical cases reported but an incidence of 1.2% of triple foramina after investigating dry skulls or radiographic. The discussion stresses the importance of adequate preoperative radiological examination in the clinical situation especially when closed surgery is planned.

The mental nerves, is primarily a sensory nerve and innervate after leaving the foramen the lower CA nines and premolars and therefore play an important role in procedures in this area such as administration of local anesthesia and surgical intervention. The absence and variation of accessory mental foramina has been reported in dry human mandibles and on radiographs previously, and can range from (0.2%) to (10.6%) on one side. A double mental foramen appears in approximately 1% on the left side in Egyptian and Polynesian populations and in 1.1% on the right side of a Melanesian group.
