ABSTRACT

Background:   Sutural bones or Wormian bones are bony ossicles rarely present in between the bones of calvaria. These bones are also called as flower’s bone or supernumerary bones usually found in the sagittal, coronal and lambdoid sutures but rarely present in fontanalle. They ossify from additional ossification centers which develop de novo in the calvarial mesenchyme. The frequency of these bones increases in various clinical conditions.
Aim:    The purpose of this study is to analyze the frequency of sutural bones, their morphology, and position to discuss their clinical importance as well as forensic importance.
Materials and Methods: Two hundred and fifty human dry skulls are used for the study from the Department of Anatomy, Andaman & Nicobar Island Institute of Medical Sciences, Portblair, Government medical college, Thirunelvelli, Sri Lakshmi Narayana Institute of Medical Sciences, Puducherry and National Institute of Siddha, Chennai. The skulls are examined and the features of sutural bones are noted.
Results: Many numbers of sutural bones mimicking skull fractures are found in this study including presence of Inca Bones/Goethe’s ossicles.
Conclusions:   Our observations may be useful in interpreting the incidental findings of sutural bony ossicles during radiological procedures, surgical interventions of skull and also in autopsy procedure.
Key Words: Lambda, Sutural bone, Inca bone, Goethe’s ossicle.
