ABSTRACT
Introduction: Meniscal tears are commonly encountered in clinical practice and cause significant musculoskeletal morbidity. Most of the data available on Morphometry of menisci in Indian population are through cadaveric studies and very few MRI studies are available to substantiate the available data. Aim of the study: To gather data on the Morphometry of menisci in South Indian population and compare it with the existing literature. Material and Method: 100 MRI images collected retrospectively were used to study menisci. Height and width of MM and LM were measured both in sagittal and coronal planes. Results: It was observed that in both sexes the height of the Anterior horn of Medial meniscus was significantly higher than that of Lateral meniscus. Width of the Anterior horn and body showed significantly higher values in Lateral meniscus whereas width of Posterior horn of Medial meniscus showed significantly higher values in both sexes. Height of Medial meniscus in all the segments was higher in males though the difference was significant only in anterior horn and Posterior horn segments. Height of Lateral meniscus was significantly higher in males in all the segments. Conclusion: Results of this study will add to the existing literature on the Morphometry of menisci and will serve as a database for patients undergoing meniscal allografts.
ABSTRACT
Background: The greater palatine foramen (GPF) conducts greater palatine nerve, responsible for the innervationof posterior part of the hard palate. Anaesthetic block for greater palatine nerve is highly recommended forsurgical practices involving upper molar, maxillary sinus and nasal region. But the practical problem associatedwith anaesthesia is difficulty in locating the exact position of greater palatine foramen, leading to deliveringinsufficient anaesthetic solution. The greater palatine neurovascular structures enter the oral cavity through thegreater palatine foramen so this foramen should be approached carefully during any surgical procedures toavoid damage to these neurovascular structure.Materials and methods: 126 dried adult skull bones of unknown sex, obtained from the department of anatomy,MVJ Medical College and Research Hospital were used to locate the exact position of greater palatine foramen inrelation to bony landmarks. On both side, the distance of greater palatine foramen from midline maxillarysuture, posterior border of hardpalate, incisive fossa and lesser palatine foramen were measured with digitalvernier caliper. Location of GPF in relation to molar or premolar tooth was also noted. The data obtained wereanalyzed statistically by calculating mean and standard deviation. The percentage was calculated for the locationof GPF in relation to molar or premolar tooth.Result: In the present study of anthropometric analysis of greater palatine foramen of 126 dried skulls, it wasobserved that the most common location of greater palatine foramen was opposite to the third molar tooth. Themean distance between greater palatine foramen to mid maxillary suture was 13.71mm on right side and13.72mm on left side and posterior border of hard palate on right side was 4.62mm and 4.49mm on left side. Themean distance between greater palatine foramen and incisive fossa was 36.73mm and 36.66mm on the right andleft side respectively. The mean distance between greater palatine foramen and lesser palatine foramen was1.47mm on right side and 1.49 mm on left side.Conclusion: Results of present study may contribute greatly to the successful outcome of maxillofacial and oralsurgeries regional anaesthesia.
ABSTRACT
Background: The challenges faced by man in early days to provide the identity of an individual. Identity meansdetermination of distinctiveness of a person, which is very important in legal medicine and criminal investigation.Cheiloscopy is a forensic investigation that deals with the identification based on lip traces. The lip prints areindividualistic like the finger prints and do not undergo alteration during the life of an individual. The aim of thepresent study to assess the lip print pattern of different individual in different quadrant of lip and to evaluate thelip prints for their uniqueness.Materials and method:The study was conducted on 100 medical students (50male and 50 females) of 18-23years from A.J.Institute of Medical Sciences, Mangalore. Lip stick was applied on the lips and print was takenwith the help of white bond paper. While studying the lip print 4 quadrants were made on the lips as upper rightand upper left and lower right and lower left. Predominant pattern in each quadrant is obtained by using Suzuki’sclassification and result s are analyzed statistically by calculating the percentage for each pattern in eachquadrant of lip.Result: The present study showed type 1(vertical) was the overall most common pattern among both male andfemales.In males, 40% were having type1(vertical), 26.5% of type3(branched), 13.5% of type2(partial length),12% of type 5(intersected) and 8% of type4 (reticular).In females, 37.5% were having type1(vertical), 22.5% of type2(partial length), 22% of type3(branched), 11% oftype 4 (reticular),and 7% of type 5(intersected).Conclusion: Study revealed that the lip prints pattern for each individual in each quadrant is unique. Lip printpatterns are constant do not change with time.Because of its uniqueness and constant nature it can be used inthe personal identification mainly for criminal and legal investigations.
