Radiographic evaluation of the course and visibility of the
mandibular canal. Imaging Sci Dent 2014;44(4):273-8.
It is possible to assert the presence of eighth canals: the preopercular canal (PR), the
mandibular canal (MD), the supraorbital canal (SO), infraorbital canal (IO), otic canal (OT), post-otic canal (PO), supratemporal canal (ST) and temporal canal (T).
Reproducibility of 3 different tracing methods based on cone beam computed tomography in determining the anatomical position of the
mandibular canal. J Oral Maxillofac Surg 2010; 68: 811-7.
* Absence of paresthesia or violation of
mandibular canal, maxillary sinus, or floor of nasal passage
However, such a margin was noted to overlap with the
mandibular canal placing the patient at high risk for transection of the inferior alveolar nerve during tumor extirpation (Figure 3).
Computed tomographic analysis of the
mandibular canal: relevance to the sagittal split ramus osteotomy.
Measurement of anterior loop length for the
mandibular canal and diameter of the mandibular incisive canal to avoid nerve damage when installing endosseous implants in the interforaminal region: A second attempt introducing cone beam computed tomography.
Cancellous bone was viable surrounding the mental nerve at the anterior margin (Figure 3(d)) and the
mandibular canal at the posterior margin (Figure 3(g)).
Mandibular alterations may be unilateral or bilateral and include enlarged mandibular and mental foramen, widened inferior alveolar canal, branching of
mandibular canal, hyperostosis, deepened sigmoid notch, elongated condylar neck, rarefied condylar and coronoid process, medial concavity in mandibular ramus, decreased or flat gonial angle, irregular inferior cortex, and cyst like lesions [1-4, 6].
Together with the inferior alveolar artery and vein, it enters the mandible via the mandibular foramen and runs an intraosseous course within the
mandibular canal before dividing into two smaller branches, namely, the mental and the incisive nerves.
The foramen receives a canal of variable depth that normally arises from the
mandibular canal behind the lower third molar, which is regarded as the retromolar canal (RMC) [1].
The
mandibular canal is referred to as a bilateral single structure; however, reports in the literature clearly show the presence of a second or even a third accessory nerve branch.
