Summary

The sphenoidal canal, a remnant of fetal skull development, was found in most Egyptian skeletal remains. This finding provides insights into early human craniofacial development and growth.

Area of Science:

  • Anatomy
  • Paleoanthropology
  • Developmental Biology

Background:

  • The sphenoidal canal's presence and significance in human skeletal remains are not fully understood.
  • Perinatal craniofacial development involves complex ossification and fusion processes.

Purpose of the Study:

  • To describe the morphology and prevalence of the sphenoidal canal in perinatal human skeletal material.
  • To investigate the developmental origin of the sphenoidal canal.

Main Methods:

  • Examination of 58 disarticulated human skeletal remains from Egypt (1918-1928).
  • Detailed description of the sphenoidal canal's extent and variations.
  • Analysis of its anatomical relationship with surrounding structures.

Main Results:

  • The sphenoidal canal was identified in 57 out of 58 specimens.
  • Significant variations in canal extent and morphology were observed.
  • The canal originates from the rostrum of the sphenoid and terminates at the tuberculum sellae.

Conclusions:

  • The sphenoidal canal represents the remnant of the sphenoidal synchondrosis.
  • This synchondrosis appears to have limited importance for growth after the perinatal period.
  • The study clarifies the spatial relationship between sphenoidal and craniopharyngeal canals.
