Background: Despite the development of anterior skull base surgery, the anatomy of the nasal bone
and anterior cribriform plate remains unclear. A recent study confirmed 2 distinct foramina in the anterior part
of the cribriform plate: the ethmoidal slit (ES) and the cribroethmoidal foramen (CF). The aim of this study
was to specify their content, their anatomic relationship to the frontal sinus and skull base, and their potential
value in skull base surgery.
Methods: Dissections were performed on 36 cadaver heads. Macro- and microscopic examinations
were carried out. Microcomputed tomography scans contrasted with osmium were performed to identify
vessels and nerves. Histology with neural, meningeal, or luteinizing hormone-releasing hormone
immunomarkers was performed on the content of the foramina. Finally, endonasal surgical dissections were
carried out.
Results: The ES and the CF were observed in all cases. They measured a mean of 4.2 and 1.6 mm,
respectively. The ES contained dura mater, arachnoid tissues, lymphatics, and the terminal nerve. The CF
contained the anterior ethmoidal nerve and artery. This foramen continued forward with the cribroethmoidal
groove, which measured a mean of 2.5 mm. This groove was under the frontal sinus and in front of the skull
base. We also described a "cribroethmoidal canal" and a "nasal bone foramen." Clinical applications are
discussed.
Conclusion: The clinical applications of this new anatomic description concern both the cribriform
plate and frontal sinus surgeries. Identifying the terminal nerve passing through the ES is a step forward in
understanding pheromone recognition in humans.
