ABSTRACT
Aim: Accessory mental foramen
(AMF) is not a common anatomical variation. During the surgical procedures
involving mandible such as implant surgery at mental region, obvious attention
should be given to prevent postoperative sequale.
Case report: Orthopantomograph
(OPG) is routinely taken to visualize the maxillofacial region at dental
clinic. OPG shows exactly upper,lower jaw and teeth, but superficially reveal
some pathology or anatomic variation. It misses sometimes anatomic landmark such as AMF. As the surgery
is planned to maxillofacial region, a detailed knowledge should be known before
go into surgery to not interfere with anatomic landmark. 52 years old male
patient was referred to Kütahya Health Science University Dental Hospital,
Turkey to rehabilitate his bilateral partial edentulous lower jaw region.
Implant surgery was planned in our patient. OPG was taken to evaluate the
maxillofacial region but is was unremarkable. Before the implant surgery, CBCT
was obtained from our patient. CBCT and a- three dimensional reconstructed
model of male patient showed bilateral accessory mental foramen (AMF).
Conclusion: CBCT should be
provided before the surgical procedures involving mandible. Accessory mental
foramen (AMF) carries additional
innervation to chin, mandibular anterior gingiva and mental region. Reflection
and protection of the AMF during the surgery can prevent hemorrhage, neurosensory
disturbance at mental region and can improve quality of life for patient.
