Mandibular Lingula as an Anatomical Reference Point for Inferior Alveolar Nerve Block.
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 3
Abstract
The conventional Inferior alveolar nerve block is the most commonly used nerve block technique for locally anaesthetizing the inferior alveolar nerve during minor and major mandibular surgical procedures. The inferior alveolar nerve passes through the mandibular foramen along with the mandibular vessels. In close association with the mandibular foramen is an elevated bony process known as the lingula. The foramen and the lingula, because of their relation to the inferior alveolar nerve are of clinical significance for the orodental surgeons.The lingula is used for identifying the approximate area of the mandibular foramen for determining the site of deposition of local anesthetic for inferior alveolar nerve blockage or for excision of nerve for facial neuralgia and other major surgical procedures. The exact location of the mandibular foramen on radiographs is not always easy to be established due to its radiolucency and the superimposition of contralateral mandibular structures. The lingula serves as an important landmark to localize the mandibular foramen as it lies in close proximity to it. Analysis also shows that failure to localize the lingula and mandibular foramen in addition to the variation in morphological characteristics account for a percentage of failure in achieving the inferior alveolar nerve block to about15-20%[1]which is lower when compared to other techniques like Akinosi and Gow Gates techniques which have more failure rates[2]Intraoperative complications such as hemorrhage, unfavorable fracture nerve injury have been documented due to improper identification of the lingula.[3]Identifying the lingula and thereby the mandibular foramen reduce the failure rate and promotes safe surgeries without potential nerve damage and hence this study.[4-9]
