ABSTRACT
OBJECTIVES:
To assess histologically the true content of the superior genial spinal foramen and to match these findings to the microanatomical canal content observed using high-resolution magnetic resonance images of the same region.METHODS:
Ten human mandibular specimens were imaged using a 9.4 Tesla MRI unit. Afterwards, eight specimens were decalcified, embedded in paraffin and serially sectioned (7 microm) for histological examination; the remaining two were embedded in methylmethacrylate and sectioned (50-60 microm). All sections were examined using routine light microscopy to inspect the superior genial spinal foramen region and its content.RESULTS:
Histological observations of the superior genial spinal foramen confirmed the presence of a well-defined neurovascular bundle, with branches of the lingual nerve and lingual artery. The canal had an average diameter exceeding 1 mm and could thus be considered significant.CONCLUSIONS:
The present study confirms the existence of a true superior genial spinal foramen's bony canal with neural and blood vessel content. These findings imply that surgical procedures should consider a proper preoperative assessment of the neurovascular trajectory of the superior genial spinal foramen.
