An Anatomico-Radiological Study of Inter-Relationship between the Mandibular Foramen and Accessory Mandibular Foramina in Population of Rajasthan State
Journal Title: Galore International Journal of Health Sciences and Research - Year 2018, Vol 3, Issue 3
Abstract
The Mandibular foramen (Mf) is present on the inner surface of the ramus of the mandible. It leads into the mandibular canal giving passage to Inferior Alveolar Nerve (IAN) and vessels which enter the roots of the teeth and the periodontal septa. Many unnamed accessory foramina are present on the lingual side of the mandible which are very variable in their distribution but they are observed more often on the internal surface of the mandible in position above or below the MF. A dental surgeon performing tooth extraction should be aware of Accessory Mandibular Foramina (AMf) for planning anaesthesia at an appropriate anatomical site as the branches of the facial nerve, mylohyoid nerve, buccal nerve and transverse cervical cutaneous nerve are known to pass through these foramina. Nerve block techniques by local anaesthetics might fail if any of these nerves or their branches pass through these AMf and escape the nerve block. The present research paper reports the presence of AMf around Mf in 25 dry human mandibles out of 100 mandibles studied and emphasizes the inter-relationship between Mf and AMf in certain cases studied radiologically. Precise knowledge and awareness of such AMf would therefore be important for dental surgeons performing nerve block and also for oncologists in planning radiation therapy.
