Abstract
|
|
|
Purpose: The lingual foramen perforates the lingual cortical plate at the mandibular symphysis containing a neurovascular bundle and supplies sensory and blood to the anterior mandible. The aims of this study were to evaluate the lingual foramen based on the mental spine in Koreans and review the literature through an electronic journal database search.
Materials and Methods: Forty-five dry mandibles were evaluated regarding incidence, location based on mental spine, and relative size of the lingual foramen located on the lingual side of the mandibular midline. The distances were measured between the inferior border of the mandible and superior lingual foramen, mental spine, and inferior lingual foramen. Literature was searched basd on the PubMed electronic journal database using the cited keywords.
Results: The lingual foramen was detected in 86.7%. A single foramen was frequently found in 53.8%, and in this case, the superior lingual foramen above the mental spine was most abundant. The mean distances of the superior lingual foramen, mental spine, and inferior lingual foramen were 14.16±1.69, 12.09±1.66, and 7.57±2.21 mm from the inferior border of the mandible, respectively.
Conclusion: These results on the lingual foramen might help to avoid hemorrhagic damage during surgical procedures such as implant placement, genioplasty, and bone grafting in the anterior mandibular region.
