Issue Date: | 2005 | Publisher: | BRITISH INST RADIOLOGY | Source: | DENTOMAXILLOFACIAL RADIOLOGY, 34(6). p. 362-368 | 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 mu m) for histological examination; the remaining two were embedded in methylmethacrylate and sectioned (50-60 mu m). 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 I 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. | Notes: | Katholieke Univ Leuven, Fac Med, Oral Imaging Ctr, B-3000 Louvain, Belgium.
