Background: The styloid process is a bony projection, located on the lower surface of the petrous part of the temporal bone just anterior to the stylomastoid foramen. Elongation as well as the anterior and medial angulations of the process may cause various clinical symptoms such as neck and cervicofacial pain, described as Eagle's syndrome.Objective: The present study aimed to determine the mean length of the styloid process on 150 dry skulls to investigate the incidence of the elongated styloid process, inter styloid distance, angulation and the relations of the styloid processes to other structures at the base of the skull, highlighting the possible importance in clinical and surgical conditions. Materials and Methods: The study was done on both sides of 150 dry skulls were selected from the museum of anatomy department of GMERS Medical College Gotri, Vadodara, and Government Medical College Bhavnagar. The length, inter styloid distance and the angulation of the styloid processes were measured and expressed as Mean ± SD. Results: The means of length and anterior and medial angles of the elongated styloid process of right side were 43.76 ± 11.05, 38.56 ± 11.53, 32.4 ± 19.54 and on left side were 43.53± 10.45, 38.7 ± 11.88, 32.56 ± 19.78 respectively. The mean of interstyloid distance were 7.5cm at base, 5cm at midpoint and 2.5cm at tip of styloid process. Conclusion: The elongated styloid process was found upto 2% of dry skull. The presence of the elongated styloid process and its angulation, though rare, does highlight the importance of routine examination of the styloid process even in clinical practice.
