The region of the exoccipital bone is delimited with the tympanohyal area (Cavum tympanicum) by the evident paraoccipital process (Proc.
The stylohyoid chain extends between the temporal bone and the hyoid bone and is divided into four sections- a) Tympanohyal (forms the base of the styloid process), b) Stylohyal (forms major portion of the styloid process), c) Ceratohyal (forms the stylohyoid ligament), d) Hypohyal (forms the lesser horn of the hyoid bone).
SP morphological calcification types were classified as per the method of MacDonald Jankowski (12), who had rated the types of elongation as follows: Pattern: (A) Region 1 = tympanohyal alone: (B) Region 2 = stylohyal alone: (C) Region 1 and 2, separate: (D) Regions 1 and 2, continuous: (E) Regions 1, 2, and 3, continuous: (F) Regions 1, 2, and 3, separate: (G) Regions 1 and 2, continuous, but separate from 3: (H) Regions 2 and 3, separate: (I) Regions 2 and 3, continuous, but separate from 1: (J) Region 3 alone: (K) Region 3 and 4, continuous (may include calcification in one other region): (L) No styloid process visible.
