Morphological Study of Sella Turcica in Gujarat State
Journal Title: PARIPEX-Indian Journal of Research - Year 2015, Vol 4, Issue 2
Abstract
Introduction: Sella turcica is situated on the intracranial surface of the body of the sphenoid bone. 80% of the sella is occupied by the pituitary gland. Any abnormality or pathology in the gland could manifest from an altered size, shape and functions of the sella turcica. Around 13% of brain tumour are found in the sella turcica. Precise knowledge of dimensions of sella turcica is required for effective and safe treatment of various pituitary disorders and in the procedure of pituitary ablation with radioactive implants. Aim: The purpose of this study is to measure the size and shape of the sella turcica and thus establish normative reference standards that could assist in evaluation and detection of pathological conditions. Materials and Methods: 263 skulls and 37 individual dried sphenoid bones (total 300 bones) were examined from the collection of the Anatomy Departments of various Medical Colleges of Gujarat. Length, depth, width and volume of sella turcica were measured with digital vernier caliper. Data were collected and statistically analyzed. Results: The mean length of sella turcica was 10.72mm and maximum length was 14.98mm and minimum was 6.46 mm. The mean width of sella turcica was 12.45mm and maximum width was 16.89mm and minimum was 8.01mm. The mean depth of sella turcica was 6.61mm and maximum depth was 11.98mm and minimum was 2.16mm. The mean volume of sella turcica was 442mm3 and maximum volume was 990mm3 and minimum was 122mm3. The mean area of sella turcica was 70mm2 and maximum area was 133 mm2 and minimum was 4mm2. Conclusions: In the present study the knowledge provided by various measurements of the size of sella turcica helps the neurosurgeon to decide which approach is to be chosen in surgery of pituitary tumours.
