Ectopic pancreas also known as heterotopic pancreas (HP) is a rare congenital anomaly, mainly found as incidental finding during autopsy or abdominal exploration for an other condition. Incidence rate is probably underestimated as patients are mostly asymptomatic; otherwise, it is capable of producing symptoms depending on its location, size, often appearing in the 4th-to-6th decades. Complications such as inflammation, obstruction, bleeding, and malignancy degeneration must be considered. Pediatrics cases are very rare, generally concerning HP within Meckel's diverticulum, manifesting by gastrointestinal bleeding and intussusception...

The hyoid bone consists of a body and two pairs of processes: the greater cornua (GC) and the lesser cornua. The GC is connected to the superior thyroid cornu (STC) by the lateral thyrohyoid ligament. The GC and the STC share a common embryological origin from the third pharyngeal arch. During anatomical dissection of a male cadaver of 56 years of age, a combined variation of the GC and the STC was found. The left GC was 27.7 mm long, and the right GC was 30 mm long. The left GC axis was in the same plane as the hyoid body, while an angle of 33° was between the right GC axis and the hyoid body plane...

PURPOSE: The mandibular foramen (MF) cannot be palpated clinically and its location is variable at the medial surface of mandibular ramus. Nevertheless, determining its exact location is very important to the oral and maxillofacial surgeon for the relevant anesthetic and surgical ramus procedures. The aim of this study was to analyze the position of MF using cone-beam computed tomography (CBCT) to help the surgeon in identifying reliable 'target area' for the inferior alveolar nerve (IAN) block and 'safety zone' for mandibular ramus osteotomies approached extra-orally...

PURPOSE: The median sacral artery (MSA) is the termination of the dorsal aorta, which undergoes a complex regression and remodeling process during embryo and fetal development. The MSA contributes to the pelvic vascularization and may be injured during pelvic surgery. The embryological steps of MSA development, anastomosis formation and anatomical variations are linked, but not fully understood. METHODS: The pelvic vascularization and more precisely the MSA of a human fetus at 22 weeks of gestation (GW) were studied using micro-CT imaging...

PURPOSE: The retention and capture functions of hand can be achieved by the consistent manner work of the extensor and flexor muscles. Therefore, it is important to know variations of the extensor and flexor muscles. METHODS: During an educational dissection, accessory heads of the extensor carpi radialis longus muscle were found on the right side in a Korean cadaver. RESULTS: The extensor carpi radialis longus muscle was originated from the lateral supracondylar ridge of the humerus and trifurcated into three heads as lateral, intermediated, and medial heads...

PURPOSE: The fetal development of the mandible is nowadays quite understood, and it is already known that craniofacial growth reaches its highest rate during the first 5 years of postnatal life. However, there are very few data focusing on the perinatal period. Thus, the present article is addressing this concern by studying the mandible morphology and its evolution around the birth with a morphometric method. METHODS: Thirty-one mandibles modelled in three dimensions from post-mortem CT-scans were analyzed...

PURPOSE: The inferior lateral genicular artery (ILGA) passes around the lateral knee joint, adjacent to the lateral meniscus (LM). ILGA injuries in total knee arthroplasty or arthroscopic surgery can result in recurrent hemarthrosis or painful pseudoaneurysms. Detailed information about the perimeniscal position of the ILGA relative to the LM is necessary to avoid these complications. METHODS: 3-T MR images of 100 knees (mean age 36.3 ± 11.2 years) were retrospectively reviewed...
