ABSTRACT
Background: Studies of non metric cranial variants have been a field of considerable interest to research workers especially because of their racial and regional importance. Methodology: Total of 28 north Indian human crania of western U.P. was studied for the incidence of Ossicle at Asterion a cranial variant. Results: Ossicle at Asterion was found in 4 (14.2%) of total human crania. Conclusion: The presence of Ossicle at Asterion found to be of considerable regional and racial significance.
ABSTRACT
Abstracts: Variations of the axillary artery have been frequently observed during routine anatomy dissection classes. These variations of vascular system are of considerable significance for surgical and radiological procedures. Accurate knowledge of these variations is desirable as well as essential as they may be mistaken for veins that may lead to formation of gangrene and even loss of hand during surgical procedures. Reported here is one such case of A unilateral superficial brachial artery with a high origin of Profunda Brachii artery (PBA) as observed during routine dissection class of medical students at Rohilkhand Medical College, Bareilly, India.
ABSTRACT
Background and objective: Studies of non-meteric cranial variants have been a field of considerable interest to research workers specially because of their racial and regional importance. Supernumerary ossicles (or Wormian bones) of the cranial vault are formations associated with insufficient rate of suture closure. It was reported that there exists racial variability among the incidence of these bones. Material and methods: Studies of fifty north Indian skulls of Rohilkhand Medical College Bareilly and Shri Ram MurtiSmarak Institute of Medical Sciences, Bareilly, U.P. were studied for the incidence of Bregmatic bone cranial variant. Results: In our study the incidence of bregmatic bone was 4%, which was higher than reported elsewhere. Conclusion: The findings are discussed in the light of available literature and are of considerable racial and regional significance. We believe that the knowledge of bregmatic bone is of importance to the neuroanatomists, neurosurgeons, radiologists, anthropologists, paediatricians and morphologists.
ABSTRACT
Background: Non metric cranial variants have always been a topic of considerable interest for research workers, as they possess racial, regional and sex dimorphic differences. These variants are also of anthropometric, genetic, morphological and forensic importance. Material and methods: 71 skulls from north indian region were studied for one of such variant, absence of mastoid foramen and presence of multiple mastoid foramen. Results: Incidence of absent mastoid foramen is 7.04 %, while bilateral incidence of absent mastoid foramen is only 1.4 %, however unilaterally mastoid foramen is absent in 5.63 %. (2.8 % on right side and 2.8 % on left side). Incidence of multiple mastoid foramina is 12.67 %, out of this it is bilateral in 8.45 %, however unilaterally it is present in 4.22 %. ( 1.40 % on right side and 2.81 % on left side).Conclusions: Findings are discussed and compared with other global studies and are found to be of considerable racial and regional significance. Knowledge of this variant is valuable in some neurosurgical and otolaryngeal procedures.
ABSTRACT
Background:- Studies of non metric cranial variants have been a field of considerable interest to research workers especially because of their racial and regional importance. Material and Methods:- Total of 40 north Indian skulls of U.P. were studied for the incidence of metopism, a cranial variant in the present study. Results:- Metopism was found in 2(5%) of total of human skulls. Conclusion:-The presence of Metopic suture found to be of considerable regional and racial significance and it simulates fracture of frontal bone, therefore its presence should be properly ruled out in X-rays.
