Abstract

INTRODUCTION: The Sella Turcica is part of the intracranial surface sphenoid bone lying behind the chiasmatic groove. The name Sella Turcica is derived from Latin meaning “Turkish saddle” (1693 Blanchard dictionary). There are six different shapes of Sella Turcica namely normal. The anterior Wall is oblique, the floor of Sella with double contour, Sella Turcica with bridging, posterior part of Sella Turcica is irregular and the dorsum Sellae is Pyramidal in shape. AIM AND OBJECTIVES: 1. To measure and analyze morphological and morphometric parameters of Sella Turcica in dry bones and cadavers. 2. To measure and analyze morphometric parameters of Sella Turcica using multidetector computed tomography. 3. To compare and analyze the data and correlate with the findings in other studies. MATERIAL AND METHADOLOGY: STUDY DESIGN: Observational descriptive study. STUDY LOCALE: South Indian population. ETHICAL APPROVAL: Approval of the study was granted by the institutional Human ethical committee of PSG Institute of Medical Science and Research. DRY BONES AND CADAVERS: 20 Dry bones and 20 cadaveric specimes were collected from department of Anatomy, PSG IMS & R. X-RAY AND CT IMAGES: 200 CT images of Sella Turcica from CT brain of normal individuals and 60 X ray images of Sella Turcica from X ray skull and x ray cervical spine were collected from the Department of Radio-diagnosis, PSG Institute of Medical Sciences and Research. RESULTS: The measurements of Sella Turcica in dry skull were as follows: ◈ The mean value of length of Sella Turcica in the present study was-11.64mm. ◈ The mean value of depth of Sella Turcica in the present study was-10.12mm. ◈ The mean value of anteroposterior diameter of Sella Turcica in the present study was- 13.60mm. The measurements of Sella Turcica in cadaveric specimens were as follows: ◈ The mean length of Sella Turcica in the present study was 12.23mm. ◈ The mean depth of Sella Turcica in the present study was 10.58mm. ◈ The mean anteroposterior diameter of Sella Turcica in the present study was 15.34mm. There was significant different in measurements of Sella Turcica dimensions in X-Ray images and CT images between male and females and also between various age groups. CONCLUSION: The current study was a different one in which it was done in dry bones, cadaveric specimens, X-Ray and CT images in the South Indian population. The study was conducted in 20 dry skulls, 20 cadaveric skulls, 60 X-Ray image of Sella Turcica from X-Ray skull/cervical spine, 200 CT image of Sella Turcica from CT head. In dry skull the length, depth and anteroposterior diameter was measured and found that anteroposterior diameter was larger than length and depth. In 75% of dry skull shape of Sella Turcica was normal.
