“…This was observed in 5 among 110 skulls with a prevalence rate of 4.5%. The prevalence of elongated styloid process in the earlier studies were 1% [ 4 ], 4% [ 17 ], 8.2% [ 18 ], and 28% [ 19 ]. The prevalence rate of the present study (4.5%) is almost similar to the rate observed by Eagle (4%) [ 19 ].…”

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.

“…A wide range prevalence of ESP in different populations have been reported by many authors. The prevalence of elongated styloid process in the earlier studies was reported as 1% [15], 4% [16], and 8.2% [17]. The 4% prevalence rate was observed by Eagle.…”

Objective: Styloid process is a slender bony projection, pointing downwards from the temporal bone. An elongated styloid process can compress the vital vessels and nerves close to it. Aim of the present study was to emphasize the styloid process morphometry and its clinical importance in study population Materials and Methods: Styloid process of temporal bone was studied by using 52 three dimensional CT scans of both sexes.Results: The mean length of the styloid process on right and left side was 3.15± 0.52cm, 3.03 ± 0.55 cm. The mean width of the right and left styloid process was 0.74 ± 0.17 cm, 0.72 ± 0.19 cm. The mean medial angulation of right and left styloid process was 61.5° ± 8.17°, 61.6° ± 6.29° respectively. Conclusion:Morphometric evaluation of the styloid process is clinically important because of its closeness to important neurovascular structures. Data obtained from the present study may useful for physicians, surgeons, radiologists, otorhinolaryngologists, dentists and for anatomists as an academic interest.

“…Considering the normal length of SP as defined by Eagle (i.e., 25 mm to 30 mm) (1937) [ 9 ], the presence of one elongated SP was observed in this research among 15 dry skulls with a prevalence rate of 6.6% of the total analyzed ( Figure 4 ). The prevalence of elongated styloid process in the earlier studies was 1% [ 23 ], 4% [ 24 ], and 8.2% [ 25 ]. The 4% prevalence rate in the present study is similar to the rate observed by Eagle.…”

Objective. To evaluate measures of the styloid process (SP) in Brazilian dry skulls. Methods. This study involves measurements of two points (lateral end posterior views) of 15 dry skulls held by the Morphology Department, Institute of Biological Sciences of Federal University of Minas Gerais. Results. There was a large variability for the length of left and right sides (in lateral and posterior views) of the styloid process. From the lateral view of the left and right styloid, the length of the SP ranged, respectively, from 10.22 mm to 69.73 mm and from 8.30 mm to 63.77 mm. From a posterior view of the left and right sides of the skulls, the values range, respectively, from 15.57 mm to 69.51 mm and from 15.64 mm to 69.44 mm. Conclusion. We believe that this study provides additional information about the frequency of elongated SP among the Brazilian population.
