| Abstract:
|
Mastoid process is the major anatomical landmark in the lateral aspect of the skull. It encloses mastoid antrums containing numerous air cells. It has communication with the middle ear cavity through mastoid aditus. Because of this communication the middle ear infection may be transmitted into the mastoid antrum. The infected mastoid antrum is drained by surgical procedures. The aim of the present study is to analyse the mastoid triangle by using morphometrically. For this the study adopted 50 south Indian dry skulls. The vernier caliper has been used to measure the mastoid triangle. The results were represented as graphs. The present study has observed that the mean distance of the porion to mastoidale was 30.9 mm and 30.9 mm on right and left side, the mean distance of mastoidale to asterion was 50.5 mm and 50.2 mm on right and left side and the mean distance of porion to asterion was 48.6 and 48.4 on right and left side. The present study thus concluded that the morphometric analysis of mastoid triangle is very important and useful in approaching the mastoid region during surgical procedures and also an effective tool to determine the sex of an individual in anthropological studies.
