“…However, it may be premature to comment on the frequency of this variant due to the small sample size. This variable branch was also presented in a case reported by Muraleedharan et al [28], where numerous variations in the branching pattern of the posterior division of the mandibular nerve were presented. In the case report, the variant recurrent branch emerged from the left IAN and supplied the lateral pterygoid muscle.…”

“…Before entering the mandibular foramen, the IAN gives rise to the nerve to mylohyoid. Communications between the IAN, lingual nerve (LN), hypoglossal nerve or the auriculotemporal nerve (ATN) have been reported [1][2][3][4][5]. The IAN is clinically important nerve, especially in dentistry so that inferior alveolar nerve blockade (IANB) is better understood [6].…”

A number of studies have previously shown variations of inferior alveolar, however, only a few reports focused on nearby the foramen ovale. In a formalin fixed cadaver, we identified three minor branches (anterior, middle, and posterior branches) arising from the main trunk of the mandibular nerve adjacent to the foramen ovale, passing lateral to the maxillary artery (MA), and joining the inferior alveolar nerve. The diameter of the branches was 0.68 mm, 1.43 mm, and 0.40 mm, respectively. The branches traveled inside the lateral pterygoid muscle (LPM) or between the LPM and tensor/levator veli palatini. Moreover, all of the branches were superficial to MA. Knowledge of such a variation might be helpful to dentists during, for example, anesthetic blockade and various oral surgeries.

“…Several studies (RODELLA, BUFFOLI, LABANCA et al, 2012) have shown that before entering the mandible, IAN can give multiple branches which are usually associated with accessory mandibular foramina and mandibular canals. Nevertheless, as reported by Muraleedharan, Veeramani and Chand (2014), in most cases where there are no associated accessory foramina, such branches innervate the LPM. In some cases this additional branch from IAN penetrates the LPM after supplying it to join the main trunk of mandibular nerve, its divisions or any of its branches.…”

“…Anatomical knowledge is essential for a diagnosis and treatment of maxillofacial disease. There are several explanations and suggest to anatomic variation, such as migration of neuroblasts and myoblasts in this area during embryogenesis (MURALEEDHARAN, VEERAMANI and CHAND, 2014).…”

Anatomical variation of the alveolar inferior nerve: a case report

Introduction: The mandibular nerve is the third and inferior division of the trigeminal nerve. One of its branches, the inferior alveolar nerve, is one among the three branches of the posterior division of the mandibular nerve, it supplies the lower jaw and teeth. However, variations of the inferior alveolar nerve branches have been of major concern in the performance of surgical procedure and anesthesia in dental and maxillofacial practice. Method and Results: A variant branch arising from the alveolar inferior nerve before it enters in the mandibular foramen were discovered during a dissection routine. The branch can be described as a variation referring to inferior alveolar nerve as a recurrent branch towards superior, posterior and medial entering in the lateral pterygoid muscle, leaving inferior alveolar nerve before the nerve for mylohyoid muscle. The nerve were found in the in both infratemporal fossa. Conclusion: Knowledge of the variations of the mandibular nerve, its branches and communications are clinically important especially for dental surgeons to understand the effectiveness of the nerve block and complications following regional anesthesia.

Abstract: Such variant branches and communications between the branches of mandibular nerve as seen in this case have an embryological basis and are clinically important in this region especially for dental surgeries and anesthesia.
