We experienced two cases of inferior alveolar nerve paresthesia caused by root canal medicaments, which were successfully relieved by microscopic endodontic treatment. In the first case, the paresthesia might have been attributable to infiltration of calcium hydroxide into the mandibular canal through the root canals of the mandibular left second molar tooth. In the second case, the paresthesia...

When the lower alveolar nerve is affected by any mechanical, iatrogenic, neoplastic or inflammatory process, we can clinically see the appearance of typical trigeminal symptoms, together with typical radiological changes of the mandibular canal, consisting in widespread hypodensity, increase in diameter and disappearINDIRECT POST-IMPLANT LESIONS OF THE INFERIOR ALVEOLAR NERVE.

Figure 1. Sural nerve grafts following end-to-end neurorrhaphies to the frontal (F), zygomatic (Z), buccal (B), marginal mandibular (M), cervical (C) branches, and the facial nerve trunk (FN). DESCRIPTION A 45-year-old man with a deep lesion to the parotid (shown to be a basal cell carcinoma on biopsy) underwent a radical parotidectomy following discussions in a multidisciplinary meeting. Durin...

Few cases of spontaneous bone regeneration after extensive resection the jaw have been reported, but there are not too many reports that show nerve regeneration. In this case, we report and healing in a 67-year-old female patient. She was diagnosed with medication-related osteonecrosis due to previous bisphosphonate use. After segmental resection, stabilization achieved using reconstruction pla...

The mandibular foramen is a landmark for procedures like inferior alveolar nerve block, mandibular implant treatment, and mandibular osteotomies. The present study was aimed to identify the precise location of the mandibular foramen and the incidence of accessory mandibular foramen in dry adult mandibles of South Indian population. The distance of mandibular foramen from the anterior border of ...

Chavez et al. [1] suggested that during embryonic development three canals fuse to form a single nerve canal. Failure of these canals to fuse can explain presence of multiple canals in some individuals. In case-1 and case2 there are bifid canals, one nerve canal is supplying the developing permanent tooth bud while the other branch is following its coarse into the mandible. To the best of our k...

The trigeminal nerve (TN) is a mixed cranial nerve that consists primarily of sensory neurons. It exists the brain on the lateral surface of the pons, entering the trigeminal ganglion (TGG) after a few millimeters, followed by an extensive series of divisions. Of the three major branches that emerge from the TGG, the mandibular nerve (MN) comprises the 3rd and largest of the three divisions. Th...

Background and aims. One of the most common reasons forthe inferior alveolar nerve block anesthesia failure is the variation in mandibular foramen location. The aim of this study was to assess the location of mandibular foramen in children with mandibular retrognathism in comparison to children with normal skeletal occlusion in the mixed dentition. Materials and methods. One hundred and twenty ...

BACKGROUND Injuries of the marginal mandibular nerve (MMN) of the facial nerve result in paralysis of the lower lip muscle depressors and an asymmetrical smile. Nerve reconstruction, when possible, is the method of choice; however, in cases of long nerve gaps or delayed nerve reconstruction, conventional nerve repairs may be difficult to perform or may provide suboptimal outcomes. Herein, we in...

mandibular canal is the most important anatomical landmark in the body of mandible which always must be considered for implant surgery in posterior mandibular region. damage to vessels and inferior alveolar nerve that passes through the mandibular canal can cause problems such as hemorrhage and neurosensory disturbances. damage to the mandibular canal can occur during implant surgery. depending...
