ABSTRACT
Background and objective: The acute appendicitis is a common and serious cause of acute abdominal pain. Oftentimes, the surgeons could not find the vermiform appendix in its usual position. A detailed study of variation positions of the vermiform appendix is necessary for an appropriate treatment. The data could also contribute to the collection of the world such as the World Health Organization from a population of the Northeast Thailand. This study aims to study and accumulate the gross anatomical data on position variation of the vermiform appendix in the Northeast Thailand cadavers. The incidence and morphometry of the structure were established.Design: A detailed dissection is the descriptive study.Materials and Methods: A total number of 102 cadavers donated by the Northeast Thailand population were carefully dissected. The identification of the urinform appendix site was done by following the three teniae coli caudally to its base where the three muscular lands meet to form a complete longitudinal, smooth muscular tube. The length was measured using the venire caliper and the percentage was calculated.Results: Among 102 specimens, the most common type of vermiform appendix is the post-ileal at 37.25% while the least common (called the pre-ileal and paracecal types) is at 3%. The approrimate length of 6 cm is the most frequent group. The average length + SD of both genders is 6.127 + 2.028 cm.Conclusion: This study discovered that the most common type of position variation of vermiform appendix is the post-ileal type at 37.25%. The average length in male and female cadavers are 6.329 + 2.012 cm. and 5.688 + 2.023 cm., respectively.Keywords: cecum, gut rotation, rotation axis, vermiform appendix, position variation, morphometry, mesoappendix, teniae coli, situs inversus
ABSTRACT
Background: Aneurysms left in the cadaver has been difficult to find in our experiences, during 34 years from the establishment of Khon Kaen University Medical School. We witnessed the first case of multiple aneurysms in 2007 in the male cadaver out of 843 of both gender specimens. We always have diagnosed and treated the patients now and then in our teaching hospital, Srinagarind.Purpose: 1) To record the basic data for clinical management of aneurysm. 2) To stimulate the interests of the medical students to make them pay more attention to gross anatomy as it is the basis for tackling the aneurysm problem early in the medical career.Materials \& Methods: We redissected 843 cadavers after the standard procedure. They were 371 females aged between 21-92 years and 472 males between 38-88 years old at the time of death. The work was accomplished in the KKU Dept. Anat. dissecting room and from 1973-2007.Results: We found 3 aneurysms in one male cadaver aged 65 years, They were, 1) right popliteal aneurysm, 2) right internal iliac aneurysm, and 3) left common iliac aneurysmConclusion: The gross lesion of aneurysm seen in the dissecting room is very exciting for the medical students and the anatomists which lead to the stimulation of the students’ interests. This leads further to the thoughts for the application in the patients. This also enhances the teaching and learning process. The other morbid anatomy in the cadaver will surely serve the same objective. The etiology was discussed.Key words: aneurysm, Northeast Thailand, etiology
ABSTRACT
Background and Objective: The surgical approaches of the neck region are very frequent. The examples are thyroidectomy, tracheotomy, and removal masses including lymph nodes. Therefore, the surgeons have to be aware of anatomical variations in the neck including the unseen and unreported ones. The present study was to report the cleidohyoid muscle in Thai cadavers as a first case in the Northeast Thailand.Methods: Re-dissection surveys had been performed on the embalmed, legally donated cadavers to Department of Anatomy, Faculty of Medicine, Khon Kaen University from 1974 to 2008.Results: The cleidohyoid muscle was observed in one male out off 939 cadavers. This muscle is present in birds and disappears somewhere along the course of evolution. The muscle helps in the process of feeding. It connects the pectoral girdle, specifically the clavicle, to the tongue skeleton especially the hyoid bone, so that the swallowing of food is possible. The incidence of this variation is very rare. It is 0.01% in this study. The developmental history and the surgical aspect of the muscle were presented. Conclusion: The occurrence of the cleidohyoid muscle in the densely packed region as in the neck requires an extremely careful procedure of the surgeons.Keywords: Gross anatomy variation, cleidohyoid muscle, mechanism of feeding, developmental history, evolution
