Introduction: Sphenoid bone is an individual bone in the cranium which is unpaired. Its shape resembles a butterfly or bat shaped containing a central body. Sphenoidal tubercle is the bony projection present within the anterior aspect of the infratemporal crest. The purpose of this research work is to bring out the morphometrical variations of sphenoidal tubercle in dry sphenoid bone and its anatomical deviations.
Materials and Methods: The osteometric study was did in 42 dry processed cranial cavity of unidentified gender. Also skulls having large breakage and developmental defects were rejected. Good selected bones were collected from Department of Anatomy, Basic Medical Science, Saveetha Dental College and Hospitals for estimation. Statistical analysis was performed in the SPSS, using a paired sample ‘t’ test.
Results: Morphological analysis shows that sphenoidal tubercle represent a different morphology and measurements. Morphometrical analysis shows that the average of right sphenoidal tubercle and left sphenoidal tubercle is 3.901 and 3.394.
Conclusion: Since the groove for maxillary artery and groove for maxillary nerve are situated nearer to the sphenoidal tubercle, it is a remarkable landmark in anatomical structures. This key landmark could be regarded as a criterion for the surgical methodology to the infratemporal fossa.
