Morphological study of styloid process of the temporal bone and its clinical implications / 대한해부학회지

The objective of this study was to study the morphometry of the styloid process of temporal bone and prevalence of elongated styloid process. The morphology of elongated styloid process along with its embryological and clinical importance are discussed. The present study included 110 human dry skulls which were procured from the bone collections of the department of anatomy. The styloid process was observed macroscopically on both sides of all the skulls, the elongations if any were noted. All the styloids were measured for their length, thickness at different levels and interstyloid distance at various levels. Out of 110 specimens, only 5 skulls (4.5%) exhibited the elongated styloid process. Among them, 3 skulls (2.7%) had unilateral elongation and 2 skulls (1.8%) had bilateral elongation of the styloid process. The mean length of the styloid process was 17.8+/-9.3 mm and 18.2+/-5.6 mm for the right and left sides, respectively. The prevalence of elongated styloid process in the present study was 4.5%. The clinical anatomy of this congenital variant is important to the neurosurgeon and radiologist, while interpreting the computed tomogram and magnetic resonance image scans. The morphological knowledge of elongated styloid process is clinically important since the course of the vertebral artery may be distorted in such situations.

Cadavers as teachers in medical education: knowledge is the ultimate gift of body donors

In most of the medical colleges in India, unclaimed bodies from various mortuaries reach the dissection hall; and here, the body donors club has yet to gain the desired dimensions. In spite of all the adverse circumstances, the cadaver and the dissection both have survived the most rigorous test of pedagological fitness--the test of time. Today, many of the Western countries have long donor waiting lists where cadavers are acquired as anatomical gifts or through body donor programmes. Thailand's approach to body donors offers a role model for resolving the present situation. The spirit of volunteerism reflects the drastic shift in public perception and a global change in approach is needed in the present time.
