Summary
Accessory foramina are common in the mandibular body, particularly on the lingual posterior aspect. Identifying one foramen suggests a high likelihood of others being present on different mandibular surfaces.
Area of Science:
- Anatomy
- Radiology
- Oral Surgery
Background:
- Accessory foramina in the mandibular body can impact surgical procedures and anesthesia.
- Understanding their prevalence is crucial for anatomical accuracy.
Purpose of the Study:
- To evaluate the distribution and prevalence of accessory foramina within the mandibular body using computed tomography (CT).
Main Methods:
- Retrospective analysis of computed tomography (CT) scans from 300 subjects.
- Examination of buccal and lingual surfaces, divided into anterior and posterior quadrants.
Main Results:
- Accessory foramina were observed in 26 (buccal posterior), 70 (buccal anterior), 132 (lingual posterior), and 59 (lingual anterior) subjects.
- A significant correlation was found, with subjects often presenting accessory foramina on multiple mandibular aspects.
Conclusions:
- The lingual posterior aspect exhibits the highest prevalence of accessory foramina.
- The presence of accessory foramina on one aspect increases the probability of their presence on other aspects of the mandibular body.
