Morphometric study of styloid process of temporal bone in Indian adult dry skull.

Background: Styloid Process (SP) of temporal bone is a spike like process which is usually straight but it can show curvature and concavity. Many important neurovascular structures are adjacent to it. These structures may be compressed due to morphological variations of styloid process when SP abnormally elongated it may pose threat to anesthetist while performing intubation. Methods: Study was carried out on 70 (50 males, 20 females) adult dry skulls. All measurements such as length, direction, thickness at base of styloid process, distance between of two processes, and distance between it and stylomastoid foramen were taken with the help of vernier caliper in millimeters. Results: We found mean length of styloid process in males on right side 17.8 mm and on left 15.4 mm. In females, it was 13 mm on right and 16.8 mm on left side. Average distance between of two styloid processes at base was 68.13 mm in males and 67.42 mm in females. Thickness at the base of styloid process, in males on right 4.53 mm and on left side it was 4.83 mm while in females on right 4.33 mm and on left side it was 5 mm. Conclusions: Neurovascular structures which lie within the territory of styloid process may be compressed due to its anatomical variation. This data may be useful for clinicians, surgeons, radiologists, anesthetists and anatomists as an academic interest.

Anatomical Study Of Arrangement Of Renal Hilar Structures In Indian Adult Human Cadavers.

Abstracts: Background: Knowledge of arrangement of renal hilar structure is essential in the era of minimally invasive surgery. Nephron sparing surgeries like partial nephrectomy by laparoscope is treatment of choice and in this surgery hilar dissection is one of the important steps. However, in literature very few reports are available regarding the different patterns of dispositions of renal hilar structures. Aim of present study was to evaluate the arrangement of renal hilar structures. Methodology: Present work was carried out on fifty seven pairs of morphological normal kidneys of embalmed cadavers. Renal hilum of each kidney was dissected carefully to see the arrangement of renal artery, vein and pelvis. Results: Arrangement of renal hilar structures showed great variation. We classified arrangement of renal hilar structures into ten different patterns. In 22.80 % kidney we observed the arrangement of hilar structures according to textbooks. We observed anterior and posterior tributaries of renal vein in 32.45% and in 41.22% kidneys pelvis was the posterior most relation. Conclusion: Present study will help to understand the better knowledge of the disposition of hilar structures for the urological surgeons, radiologist and anatomists.
