Cephalometry deals with measurement of body parts or radiological specimen. Sella turcica is an important anatomical structure located in the middle cranial fossa, housing the pituitary gland. Various shapes and sizes of the sellae turcica were reported. In this study, using computerized tomographic (CT) scans from a tertiary hospital, one hundred and seventy five (175) scans were analyzed using Radiant version 4.2 (Medixant 2017) for determination of sizes and shapes of the sella. Average dimensions from the study include: Length (12.4 mm), A-P diameter (14.1 mm), depth (9.6 mm) and transverse diameter (13.8 mm). Shapes were classified as being round (56.6%), oval (32%) and flat (11.4%). In another classification of shape variation, the findings are: Normal (68.6%), anterior oblique (9.1%), pyramidal (6.9%), double contour floor (5.7%), notching on the posterior wall (5.1%) and sella bridge (4.6%). Males tend to have higher sella sizes than females and there is statistical significant difference between them especially in respect to A-P diameter and length parameters. However, there is no sex predilection to shapes.
Background: The superior mesenteric artery may be the source of the common hepatic, gastroduodenal, accessory right hepatic, accessory pancreatic or splenic arteries. Objective: To present three cases of accessory right hepatic artery originating from the superior mesenteric artery in black African cadavers as found during routine cadaveric dissections. Materials and Method: The abdomens of 8 adult male black African cadavers were dissected according to the description and guidance by Romanes (1996). The superior mesenteric arteries, liver (especially the visceral surfaces), gall bladders, cystic ducts, portal veins and gastroduodenal arteries were exposed. Results: Three cadaveric cases of the accessory right hepatic arteries arising from the superior mesenteric arteries were observed. One of the cases was noticed to give a cystic branch. Conclusion: Since there are no Nigerian studies on the accessory right hepatic artery arising from the superior mesenteric artery, these reports might contribute useful data to the literature regarding the same.
Cephalometry deals with the measurement of the head or radiological specimen of the head. Sella turcica is an important anatomical structure located in the middle cranial fossa, housing the pituitary gland. Various shapes and sizes of the sellae turcica have been reported. However, in this study, using computerized tomographic (CT) scans, one hundred and seventy-five (175) scans were analyzed using Radiant version 4.2 for determination of sizes and shapes of the sella. Average dimensions from the study include length (12.4mm), A-P diameter (14.1 m), depth (9.6 mm) and transverse diameter (13.8mm). Shapes were classified as being round (56.6%), oval (32%) and flat (11.4%). Males tend to have higher sella sizes than females and there are statistically significant differences between them especially in respect to A-P diameter and length parameters. Also, there is a statistically significant relationship between age groups in terms of A-P diameter and depth of the sella turcica. However, there is no correlation between age and shapes found in the study.
Background:Objectives:Methods: Identification of human remain requires a comparison between ante-mortem and post-mortem evidences, as such, the use of bones that are often easily recovered intact like the maxilla, becomes necessary although the skull and other bones may be badly disfigured. To determine the precision with which the maxillary sinus volumes identifies sex. 130 subjects (79 males and 51 females), between 20 - 80 years, with normal maxillary sinus CT anatomy, from head CT scans carried out at the Radiology Department of the Usmanu Danfodiyo University Teaching Hospital (UDUTH) Sokoto from 2008 to 2012 were involved in this study. The volume of each sinus was determined by the product of three linear measurements (craniocaudal (height), anteroposterior (dept) and transverse (width) diameters), using Neusoft Dual Slide Helical CT machine and the slice thickness. These measurements were performed on three-dimensional reconstructed images using V-works 3.0 program. The discriminant analysis showed that the accuracy with which the maxillary sinus volume could identify sex was 50.6% in males, and 60.8% in females. Computerized Tomography estimation of maxillary sinus volume may be of value to support sex determination in forensic anthropology.
