Relationship of the mandibular canal
to the lateral cortex of the mandibular ramus as a factor in the development of neurosensory disturbance after bilateral sagittal split osteotomy.
Bifid mandibular canals
: Cone beam computed tomography evaluation.
Caption: Figure 1: (a) Extraoral frontal view shows swelling on right side of face, (b) intraoral view shows alveolar enlargement and missing teeth on right side, (c) OPG shows intraosseous radiolucency (chevron) with impacted 46, enlarged mandibular canal
(1), enlarged mental foramen (2), deep sigmoid notch (3), narrow condyle and pseudoelongation of condylar neck (4), notching of gonial angle (5), and supernumerary tooth in maxilla (6).
Hence, it is essential to have an in-depth knowledge of the location and the course of the mandibular canal
as panoramic radiographs do not provide information on the horizontal (buccolingual) position of the IAN .

: Literature review and case report," Dentomaxillofacial Radiology, vol.
Seventy-five CBCT scans previously diagnosed with bifurcation of the mandibular canal
were obtained from the database of two private dental radiology clinics located in the cities of Sao Paulo, SP, and Joinville, SC, Brazil.
Later on, the rapid process of membranous ossification of the jaw determines the formation of the mandibular canal
, being able to configure this division.6
A descriptive study was conducted using cone beam computed tomography (CBCT) to characterize the mandibular ramus area in adult patients who consulted in the Oral and Maxillofacial Surgery Unit of the Universidad de La Frontera, Temuco, Chile, measuring the distances between the mandibular canal
and the alveolar, buccal and lingual margins.
Three-dimensional radiographic techniques are of inestimable assistance, not only in differential X-ray diagnosis but also in determining the displacement space of the mandibular canal
The location and size of KCOT, cortical expansion, cortical perforation, relation with the impacted teeth, and the impact on the mandibular canal
