Abstract

Introduction: Henle’s spine is also called, spina supra-meatalis, meatal spine, spine supra-meatica, spine meatus is a bony minor eminence which is present front to supramastoid cavity. JACOB HENLE has mentioned suprameatal spine as a dependable guiding structure for the localization of the foramina during surgeries. As it has a key position it could be an important anatomical landmark or could have clinical importance. So this study has aimed to study and assess the morphometric alterations of suprameatal spine in the dry processed human skull of south indian population.
Materials and Methods: The work was done using 65 dry processed human skulls obtained from Department of Anatomy, Basic Medical Science, Saveetha Dental College. The length of the suprameatal spine was measured in vernier caliper. Results are tabulated and analyzed in SPSS. The study adopted the rank test of Wilcoxon for biostatistical investigation with p < 0.05 is fixed to be significant for current data analysis.
Results: There is no significant difference between the right and the left spine of Henle. The significant value is 0.575. It is evident in which there is no major significant difference regard to the length of right adjacent side and left adjacent side of the mastoid region. It was hard to find an undamaged Henle’s spine because of its size and delicacy. Only few specimens were studied, the study is done in a small geographical area. It has to be done in a wider population with more number of specimens.
Conclusion: The length of the spine is studied hence it will be of clinical importance. It will add up information to the surgeon on the anatomical position of Henle’s spine
