Parvindokht B, Reza DM, Saeid B - J Craniovertebr Junction Spine (2015 Jul-Sep)

Bottom Line: Study on morphometry of (HC) and its variations has been a considerable interest field to neurosurgeons and research workers especially because of their racial and regional.There were significant difference between distances of: a-(HC) till anterior tip of condyles (right and left), b-(HC) till posterior tip of condyles (right and left), c-(HC)till lower border of occipital condyles (right and left), d-(HC) till external border of foramen jugular (right and left), e-(HC) till opisthion(right and left), f-(HC) till carotid canal (right and left), g-(HC) till jugular tubercle (right and left).There wasn't significant difference in other parameters.

ABSTRACT

Background: The hypoglossal canal (HC) is in basal part of cranium that transmits the nerve that supplies the motor innervations to the muscles of tongue. Study on morphometry of (HC) and its variations has been a considerable interest field to neurosurgeons and research workers especially because of their racial and regional.

Material and methods: In this retrospective study, 26 adult dry human crania of no sex known were studied for (HC) and its variants. Thirty five skulls were observed for any damage of post cranial fossa and those in good condition (26 skulls)were selected. Sliding Vernier caliper was used for morphometric analysis.

Results: There were significant difference between distances of: a-(HC) till anterior tip of condyles (right and left), b-(HC) till posterior tip of condyles (right and left), c-(HC)till lower border of occipital condyles (right and left), d-(HC) till external border of foramen jugular (right and left), e-(HC) till opisthion(right and left), f-(HC) till carotid canal (right and left), g-(HC) till jugular tubercle (right and left). There wasn't significant difference in other parameters.

Conclusion: Detailed morphometric analysis of (HC) will help in planning of surgical intervention of skull base in safer and easier ways.

Figure 1: The location of intra and extracranial orifices of hypoglossal canal

Mentions: Twenty-six dry skulls were chosen from the archives of our department (Department of Anatomy, Arak University of medical sciences, Arak-Iran), thus we provided 52 HCs and 26 foramina magna. By using standard calipers and goniometers, 21 parameters were analyzed. We assessed 13 parameters: The length of the HC, diameter of the intra and extracranial ends of the HC, distance of the HC from the posterior, anterior and inferior margins of the occipital condyle, distance of the HC from the basion, opisthion, carotid canal and jugular tubercle, distance of the HC from the jugular foramen intra- and extracranially, anteroposterior, and transverse diameters of the foramen magnum. We have identified the location of the HC according to following Figure 1 and Table 1. In this study, all measurements were made separately for right and left sides.
