Research paper thumbnail of A Study on Course and Variations of Facial Artery on the Face

Variations in the course and branching pattern of facial artery are commonly seen. The understanding of these variations of facial artery plays a very important role in facio-maxillary surgeries. It is also of immense importance to radiologists in interpreting facial artery angiography. Materials and Methods: The present study was conducted in the Department of Anatomy, Subbaiah Institute of Medical Sciences on 50 formalin fixed adult hemi-faces irrespective of sex. The branching pattern, terminations and variations of facial artery on the face were studied. The facial artery predominantly terminated as angular artery in 28 (56%) hemi-faces, as superior labial artery in 15 (30%) hemi-faces and as lateral nasal artery in 6 (12%) hemi-faces. Results: An inconstant posterior (pre-masseteric) branch of facial artery was observed in 3 (6%) hemi-faces. In one of the hemi-face we found a deviation in the usual course of facial artery, where the artery deviated towards the infra-orbital foramen then continued and terminated as the lateral nasal artery. An unusual termination of facial artery was observed in one of the hemi-faces where the artery terminated by giving 4 branches in the lower buccal region. Conclusion: Knowledge of these variations and anomalous branching pattern is of great academic and clinical significance in general practice, Otorhinology, Traumatology, Plastic and Maxillofacial surgeries and Radiology.

This fluid is an ultrafiltrate of plasma. It is clear and colorless. It contains glucose, electrolytes, amino acids, and other small molecules found in plasma, but has very little protein and few cells. CSF protects the central nervous system from injury, cushions it from the surrounding bone structure, provides it with nutrients, and removes waste products by returning them to the blood. CSF is withdrawn from the subarachnoid space through a needle by a procedure called a lumbar puncture or spinal tap. CSF analysis includes tests in clinical chemistry, hematology, immunology, and microbiology. Usually three or four tubes are collected. The first tube is used for chemical and/or serological analysis and the last two tubes are used for hematology and microbiology tests. This reduces the chances of a falsely elevated white cell count caused by a traumatic tap (bleeding into the subarachnoid space at the puncture site), and contamination of the bacterial culture by skin germs or flora.

Research paper thumbnail of Variations of Sciatic Nerve Bifurcation: A Study

It is formed in the pelvis from the ventral rami of the fourth lumbar to the third sacral spinal nerves and leaves the pelvis via the greater sciatic foramen below pyriformis and divides into Common Peroneal nerve (CPN) and Tibial nerve (TN) at the superior angle of popliteal fossa. High division of the sciatic nerve is the most common variation wherein the TN and the CPN may leave the pelvis through different routes. Such variations may lead to compression of the nerve, non discogenic sciatica, pyriform syndrome and also to incomplete sciatic nerve block. Knowledge regarding this may help the surgeon to plan for various surgical intervention pertaining to the gluteal region. Aim: To study the course and division of sciatic nerve. Methodology: The study was conducted in the department of Anatomy, Subbaiah Institute of Medical Sciences over a period of 5 years. 70 lower extremities of 35 cadavers of both sexes were...

Research paper thumbnail of Study of Complete ossification of the superior transverse scapular ligament in Human dry Scapulae

Aim: To study the complete ossification of superior transverse scapular ligament and its frequency of distribution in various population of different region. Materials and Method: 65 dry scapulae were collected and studied with naked eye examination. Results: Macroscopic observation revealed that 6 scapulae (5-left side, 1-right side) out of 65(9.2%) scapulae had a complete ossification of superior transverse scapular ligament. Conclusion: This anatomic information is important in the management of suprascapular nerve entrapment neuropathy or interventional procedure at the supra suprascapular nocth.

Materials and Methods: Various dimension of the atlas vertebrae were quantitatively measured using a vernier caliper that provides accurate resolution up to 0.01 mm. The results were analyzed statistically using SPSS 12 version Results: The distance between the tips of transverse process of the atlas (atlas width TD), 72.45mm.Inner distance between medial margins of foramina transversaria, 43.88mm outer distance between the lateral margins of foramina transversaria 56.31mm.. Distance between the medial margin of the vertebral artery groove from the median plane [right-12.28 mm and left side-11.54mm]. Distance between the lateral margin of the vertebral artery groove from the median plane [right side-22.80mm and left side-22.87mm] and Thickness of the groove [right-3.68mm and left side-3.70mm] Outer anteroposterior(AP)diameter of vertebral foramen-42mm and inner AP diameter of vertebral foramen 28.51mm and transverse diameter vertebral foramen-27.39mm were noted. Superior articular facet AP diameter [right-22.33mmand left-22.25mm] Superior articular facet transverse diameter [right-8.74and left 9.57mm] Inferior articular facet AP diameter [right 18mm and left-17.81mm] and inferior articular facet transverse diameter [right 14.83mm and left 14.49mm]. Height of the anterior arch-10.02mm and posterior arch-8.91mm was recorded Conclusion: The quantitative anatomy of atlas may be helpful for neurosurgeons in avoiding and minimizing the complications such as vertebral artery injury, spinal cord injury and cranial nerve damage during the operation close to atlanto-occipital area.
