Background: The purpose of this study was to describe the morphology and measure the size of the sella turcica in North Indian population. Methods: Lateral cephalometric radiographs of 180 individuals (90 males and 90 females) with an age range of 12-65 years were taken. Morphology of sella turcica was studied and various measurements were taken to determine the shape of the sella. Statistical analysis was done to calculate differences in dimensions and to establish if any, relationship exists between age, sex and the morphometry of sella turcica. Results: The study found that sella turcica presented with a normal morphology in only 28 per cent of the subjects. A significant difference in linear dimensions between genders was found in sella height and width. When age was evaluated, some dimensions showed negative correlation with the age. Sella size of the older age group was as a rule larger than the younger age. Conclusion: Pathological enlargement of the pituitary fossa can be detected by this technique and may also be helpful in providing data in the assessment of racial, gender, age specific variation in the skull.

Pterion a cranio-metric point has been described according to its location, type and relationship with the surrounding bony landmarks. Approach through pterion is mostly used to treat lesions of anterior and middle cranial fossa. Pterion ossicle or Epipteric bone are sometimes mistaken as a fracture at this point. AIM & OBJECTIVE: The study was set to explore the morphometry of Pterion in the human dry skulls of Uttarakhand region. The data may be useful for the anthropologists, forensic pathologists, neurosurgeons and maxillo-facial surgeons. MATERIAL AND METHOD: 40 dry human skulls of unknown sex collected from the department of anatomy of SGRR medical college. Instrument used for linear measurements-Sliding Caliper. ANALYTICAL TEST: Students 't' test. RESULT: Sphenoparietal type accounted 86.25%, frontotemporal 11.25% and stellate 2.5% collectively on the both sides of skull. The pterion is located 3.25 ±1.05cm behind frontozygomatic suture and 3.76 ±6.62cm above the temporozygomatic suture. CONCLUSION: Pterion is less likely to be diagnosed as a fracture site due to nonoccurrence of epipteric type of pterion in human skull of Uttarakhand. Pterion can be easily located with its relation to bony landmarks, and is most preferable approach in neurosurgery.

Introduction:The anatomical knowledge of renal artery variations is gaining importance due to increased incidence of kidney transplantation and related surgical procedures. Normally a single renal artery supplies each kidney. Accessory renal arteries are the commonly seen renovascular variations. So a thorough knowledge of renal arteries is helpful for the smooth conduct and interpretation of interventional radiological procedures and to avoid unexpected complications during surgery. Subjects and Methods: In our study we decided to find out the incidence of accessory renal arteryand also there length and diameter. Results: We studied 60 patients who came for abdominal CT angiography. In CT angiography out of 60 cases 21 cases (35%) had renal artery variation, out of 21 cases 3 cases had bilateral renal artery variations and 2 cases had double accessory renal artery. Conclusion: Knowledge on renal artery variations are necessary during renal transplantation, urological procedures and for radiological interventions.
