Multiple scapula defects or foramina or both?

The current bone report describes multiple openings identified in a dried scapula of a subject of unknown age and gender. Multiple openings (twelve) were identified in the subscapular fossa and were apparent at the infraspinatus fossa. These openings coexisted with a suprascapular foramen and an osteophyte at the inferomedial border of the foramen. In the current literature, two uncommon variants of the scapula were described: foramina and defects. It is still unclear how these two structures are differentiating. Both of them are results of abnormal ossification of the scapula. Clinicians should be aware of these variants because they may lead to misdiagnosis of malignancies, while the variants are benign entities.

Treatment strategies for inverted papillomas with intracranial or intraorbital involvement.

OBJECTIVE: Sinonasal inverted papillomas are challenging benign tumours of the nasal cavity because of their high recurrence rates and the lifetime malignant transformation risk of 10 per cent as well as their locally aggressive behaviour. This study aimed to describe treatment strategies for inverted papillomas with intracranial or intraorbital involvement. METHOD: This was a prospective case series study of 18 patients with inverted papilloma with intracranial or intraorbital involvement. Patient demographic data, imaging, pathology, surgical technique and recurrences were recorded prospectively over a period of seven years. RESULTS: A total of 83 per cent of the patients in this study had been previously operated on, consisting of 8 cases with intracranial involvement, 1 case with intraorbital involvement and 9 with both. During follow up with a medium of 37 months (range, 13-115 months) there were two recurrences. CONCLUSION: It was postulated that intracranial or intraorbital involvement observed in this series was the result of multiple revisions. However, using accurate imaging protocols and the pedicle-oriented approach for tumour excision, complete tumour removal was achieved in most cases with minimal post-operative complications.

Surgical anatomy of the lateral circumflex femoral artery branches: Contribution to the blood loss control during hip arthroplasty.

BACKGROUND: The lateral circumflex femoral artery (LCFA) branches encountered during anterior and lateral hip approaches; although vessels' haemostasis is suggested in surgical textbooks, literature is scarce regarding their topography. The current study defines the exact location of the LCFA and its branches, based on osseous landmarks, as well as their size and possible variants, providing helpful information for intraoperative identification and demonstrating the magnitude of potential haemorrhage during hip surgery. METHODS: Twenty-three human cadavers (46 lower limbs) were dissected. The LCFA branching pattern was recorded. The distances of the LCFA origin and its first branch from the anterior superior iliac spine (ASIS) were measured. Length and width of the LFCA, LCFA ascending and transverse branches (LCFAab and LCFAtb) were calculated and compared to the ipsilateral ulnar artery (UA) width, which was served as a comparative guide. RESULTS: The LFCA origin was located 106.9 ± 17.5 mm distal and 65.6 ± 14.7 mm medial to the ASIS, while the LFCA first branch origin was 115.1 ± 24.3 mm distal and 48.2 ± 14.3 mm medial to the ASIS. The mean lengths of the LCFA, LCFAab and LCFAtb were 23.2 ± 12.6 mm, 44.8 ± 14.9 mm and 42.3 ± 13.6 mm, respectively. Their mean widths were 4.3 ± 1.0 mm, 2.9 ± 0.9 mm and 2.7 ± 0.7 mm, respectively, while the mean UA width was 2.7 ± 0.4 mm. CONCLUSION: The surgeon may detect the LCFA and its branching, at a mean distance of 110 mm (range 100-126 mm), distal to the ASIS. The LCFAab and LCFAtb widths are similar to the UA width. Meticulous knowledge of the branching pattern topography and vessels' size may contribute to a successful management of the intraoperative blood loss.

A prefix brachial plexus with two trunks and one anterior cord.

The brachial plexus presents a great variability in formation, division and branching pattern. Its variants are of immense importance during axillary and arm surgery and nerve blockade. The current case highlights a unilateral atypical formation of brachial plexus, the so called prefix, in which the C4 root contributed a large branch to the superior trunk and further anastomosis with the inferior trunk. Thus, the prefix or high brachial plexus consisted of a superior and inferior trunk and one anterior cord. Coexisting neural and arterial variations are also discussed in relation to the data literature.

Accessory muscles of the anterior thoracic wall and axilla. Cadaveric, surgical and radiological incidence and clinical significance during breast and axillary surgery.

BACKGROUND: The present study aims to summarise the accessory muscles of the anterior thoracic wall and axilla that can be encountered during breast and axillary surgery and record their incidence and clinical significance. Moreover, the laterality of the atypical muscles is highlighted and possible gender dimorphism is referred. Accessory anterior thoracic wall muscles include: Langer's axillary arch, sternalis muscle, chondrocoracoideus, chondroepitrochlearis, chondrofascialis, pectoralis minimus, pectoralis quartus and pectoralis intermedius. MATERIALS AND METHODS: The anatomical, surgical and radiological literature has been reviewed and an anatomical study on 48 Greek adult cadavers was performed. RESULTS: Literature review revealed the existence of accessory muscles of the anterior thoracic wall and axilla that have a significant incidence that can be considered high and may, therefore, have clinical significance. For the most common of these muscles, which are axillary arch (Langer's) and sternalis muscle, the cadaveric incidence is 10.30% and 7.67%, respectively. In the current cadaveric study, accessory thoracic wall muscles were identified in two cadavers; namely a bilateral sternalis muscle (incidence 2.08%) extending both to the anterior and posterior surface of the sternum and a left-sided chondrocoracoideus muscle (of Wood) (incidence 2.08%). CONCLUSIONS: Despite the fact that accessory anterior thoracic wall and axillary muscles are considered to be rare, it is evident that the incidence of at least some of them is high enough to encounter them in clinical practice. Thus, clinicians' awareness of these anatomical structures is advisable.

From thyroid cartilage to thyroid gland.

The ancient Greek physicians skipped the description of thyroid gland probablydue to their difficultly to understand the anatomy and the existence of this organ.Although the ancient physicians had described the disease bronchocele (Greek:Βρογχοκήλη), this disease did not correspond exactly to goitre. The first officialdescription of this gland was made by Andreas Vesalius (1514-1564). Thomas Wharton (1614-1673) in his work Adenographia was the one who coined the term 'Glandulae thyreoidea'.

Body donation for research and teaching purposes: the contribution of blood donation units in the progress of anatomical science.

BACKGROUND: Cadaver's dissection has a fundamental role in teaching and understanding the anatomy. Postmortem body donation (PMBD) is an important source of cadavers and provides an opportunity to carry out research or educational activities in medicine and surgery. The objective of the current study is to determine the perspectives and attitudes toward PMBD among blood donors (BLD) and elderly people. These data are fundamental to highlight the PMBD extent and individual factors that might influence PMBD. MATERIALS AND METHODS: Six hundred and fifty questionnaires were distributed to 500 (327 male and 173 female, mean age 39.9 ± 9.6 years) blood donors (BLD) and 150 elderly people (62 males and 88 females, mean age 74 ± 9.4 years). A specially designed self-administered questionnaire covering demographic data, knowledge and attitude of the participants concerning body donation (BD) was used. RESULTS: Concerning the perception of BD among BLD and elderly people, the most common reason for BD in both study groups was the contribution in research, while the commonest reason for hesitating about BD was the lack of information, following by personal reasons. The BLD were more likely to be interested in BD for contribution in research and personal reasons. Additionally, BLD were less likely than the elderly to hesitate about BD for religious and personal reasons and more likely to hesitate about BD for not being informed. BLD who were interested in BD for contribution in research were significantly older. Elderly people who hesitated about BD for personal reasons were significantly older. In the BLD group, those who responded that blood and body donation are the same were significantly younger, while in the elderly group - significantly older. The proportion of BLD who declared that blood and body donation is the same was significantly higher in more educated people. CONCLUSIONS: A need for well-organised and informative BD programmes is evident. Orientating the public towards this practice is of high moral and medical value, since with this important promotion the altruistic act of BD will expand globally.

Unilateral asymmetrical anterior bellies of the digastric muscle in coexistence with accessory muscle bundles in the submental triangle: A rare case report.

A three-headed anterior belly of the digastric muscle (ABDM) on the right side of a 54-year old Greek male cadaver coexisted with two accessory muscle bundles (AMB) in the submental region. The left ABDM was typical. Typical ABDM was attached to the digastric fossa, while the accessory right anterior bellies to the lower border of the mandible. A muscle bundle arising from the attachment of the left ABDM to the hyoid bone was also observed fusing with the AMB of the ipsilateral side. It is of extreme importance to be aware of the submental region anatomical variations during surgery, imaging interpretation or differential diagnosis of neck masses.

Anastomotic loop between common hepatic artery and gastroduodenal artery in coexistence with an aberrant right hepatic artery.

Anatomical variations of the hepatic arteries are not uncommon. The anomalous hepatic arterial supply is of paramount importance in hepatobiliary, pancreatic or liver transplantation and in laparoscopic surgery. We describe an unusual case of a 66-year-old Greek male cadaver, where a rare anastomosis (in the form of an enlarged arterial loop, 4.84 mm in diameter) between the common hepatic artery (6.42 mm) and the gastroduodenal artery (GDA) (4.82 mm) coexisted with an aberrant right hepatic artery (ARHA) (6.38 mm) originating from the superior mesenteric artery. The proper hepatic artery was absent. The ARHA followed a route posterior to the portal vein and the common hepatic duct, entering the liver and supplying the right hepatic segment. A hypoplastic right gastric artery emanated from the GDA. Our case report highlights the combined variations of hepatic arteries and possible anastomoses emphasizing that a thorough knowledge of the classic and variable hepatic arterial anatomy are mandatory for surgeons and radiologists performing hepatic surgery and arteriography to avoid potential iatrogenic injuries in hepatobiliary and pancreas area and further medico-legal implications.

Foramen magnum, occipital condyles and hypoglossal canals morphometry: anatomical study with clinical implications.

BACKGROUND: Current study examines morphometric alterations of the foramen magnum (FM), occipital condyles (OCs) and hypoglossal canals (HCs) and highlights all the morphometric parameters of the FM area that present side asymmetry, gender dimorphism and are affected by the ageing. MATERIALS AND METHODS: One hundred and forty-one (73 male and 68 female) Greek adult dry skulls were examined. RESULTS: Short and long OCs were detected in 27.7% and 26.2%. A combination of short OCs and long HCs was presented in 27.5%. A complete septum was found in 23.6% of the HCs and osseous spurs in 12.9%. Side asymmetry was detected regarding the HCs length (p = 0.046), the maximum extracranial (p = 0.001) and minimum intracranial (p = 0.001) diameters. Mean FM anteroposterior and transverse diameters, FM perimeter and FM surface area were significantly larger in male than in female skulls (p = 0.001 for each parameter). Similarly, the OCs length (right, p = 0.004 and left, p = 0.024) and width (right, p = 0.008 and left, p = 0.006) the left distance HC-OC posterior border (p = 0.048), the anterior (p = 0.011) and posterior (p = 0.001) intercondylar distances and the HCs right length (p = 0.046) were significantly greater in males. A significant decrease was observed with ageing in FM anteroposterior diameter (p = 0.038), FM surface area (p = 0.05), anterior intercondylar distance (p = 0.014) and HC-OC posterior border (p = 0.013). CONCLUSIONS: The study confirmed that only specific HC dimensions showed side asymmetry (HCs maximum extracranial and minimum intracranial diameters and HCs length), gender dimorphism (HCs right length and left distance HC-OC posterior border) and age influence (HC-OC posterior border and HC left extracranial minimum diameter) among young, adults and elderly individuals. FM and OCs dimensions presented gender dimorphism and the age influenced only FM anteroposterior diameter and surface area and the anterior intercondylar distance. The safe zone of OCs drilling in Greeks, calculated by the distance HC-OC posterior border represents the maximum HC depth and is among the lowest values reported in the literature. The significant decrease of this distance with ageing confirms the existence of a drilling safe zone for young, adults and elder individuals. Regarding OCs length, the same probability exists dealing with a short or a long OC during condylectomy. Before planning a transcondylar approach, the coexistence of short OCs and long HCs should be taken into account. These outcomes will be useful for a safe surgery in the craniocervical region in Greeks.

Retro-oesophageal right subclavian artery in association with thyroid ima artery: a case report, clinical impact and review of the literature.

A 37-year-old female Caucasian cadaver with an aberrant right subclavian artery extending from the left side of the aortic arch and following a retro-oesophageal course is presented. A non-recurrent right laryngeal nerve and a thyroid ima artery arising from the lower part of the middle third of the right common carotid artery coexisted. The brachiocephalic trunk was absent, while both common carotid arteries and left subclavian artery followed their normal course. The aim of the current study is to highlight the clinical impact of the above abnormalities providing useful and practically applicable knowledge to interventional clinicians, thoracic and neck surgeons, since the vast majority of documented cases with an arteria lusoria are clinically silent and in most cases discovered incidentally. Clinical manifestations such as dysphagia, chronic cough, and acute ischaemia to the right upper limb may occur, leading to misinterpretation in radiographic examination and complications during neck and thoracic surgery. Review of the literature was also performed and the embryological background of the aberration is highlighted.

Giacomini vein: thigh extension of the small saphenous vein - report of two cases and review of the literature.

BACKGROUND: Varicose vein surgery is very commonly performed. Also, it is very frequently employed for recurrent disease. The recognition of the normal or variant veins, inducing incompetency, is a prerequisite for effective treatment. The thigh extension of the small saphenous vein, the so-called Giacomini vein, was extensively described in 1873 by Carlo Giacomini in an incidence of 72%. However, such a vein is usually underestimated in classic surgical textbooks. DESCRIPTION OF CASES: We present two cases of Giacomini vein found in two cadavers, dissected for academic purposes in the Department of Anatomy, where the small saphenous vein displayed a thigh extension without terminating into the popliteal vein. In one case Giacomini vein drained into the large saphenous vein, while in the other case the vein divided into two branches, separately draining into the large saphenous vein and the subcutaneous tissue of the gluteal region. CONCLUSION: Due to the fact that Giacomini vein could be incompetent, associated with or without varicose saphenous vein trunks, the vascular surgeon should keep in mind that anatomical entity, to include it in preoperative ultrasound scanning control. Moreover, this vein could be utilized as an autologous graft, when the large saphenous is not available. Hippokratia 2015; 19 (3): 263-265.

A morphometric anatomical and comparative study of the foramen magnum region in a Greek population.

BACKGROUND: The foramen magnum (FM), a complex area in craniocervical surgery, poses a challenge for neurosurgeons. The knowledge of the detailed anatomy of the FM, occipital condyles (OC) and variations of the region is crucial for the safety of vital structures. This study focuses on the FM and OC morphometry, highlights anatomical variability and investigates correlations between the parameters studied. MATERIALS AND METHODS: One hundred and forty-three Greek adult dry skulls were examined using a digital sliding calliper (accuracy, 0.01 mm). RESULTS: Mean FM width and length were found 30.31 ± 2.79 and 35.53 ± 3.06 mm, respectively. The commonest FM shape was two semicircles (25.9 %), whereas the most unusual was irregular (0.7 %). The OC minimum width, maximum width and length were 5.71 ± 1.61, 13.09 ± 1.99 and 25.60 ± 2.91 mm on the right, and 6.25 ± 1.76, 13.01 ± 1.98 and 25.60 ± 2.70 mm on the left side. The commonest OC shape was S-like and the most unusual was ring, bilaterally. The mean anterior and posterior intercondylar distances were 19.30 ± 3.25 and 51.61 ± 5.01 mm, respectively. The OC protruded into the FM in 86.7 % of the skulls. Variations such as a third OC existed in 5.6 % and basilar processes in 2.8 %. Posterior condylar foramina were present in 75.5 %. The gender was correlated with FM width and length, OC length, bilaterally, anterior intercondylar distance (AID) and posterior intercondylar distance (PID). The OC protrusion and existence of posterior condylar foramina were correlated. Bilateral asymmetry for OC shape was statistically significant. CONCLUSION: Our results provide useful information that will enable effective and reliable surgical intervention in the FM region with the maximum safety and widest possible exposure.

The great surgeon Jean-Louis Faure (1863-1944) and his contribution in the treatment of uterine cancer.

At the beginning of the 20th century, Professor Jean-Louis Faure, one of the leading surgeons of the innovative Parisian Medical School, published an exhaustive work on uterine cancer. He was the first to perform in France the procedure of total abdominal hysterectomy by median section of the uterus contributing to the evolution of cancer surgery.

Anatomic variability in the relation between the retromandibular vein and the facial nerve: a case report, literature review and classification.

Knowledge of anatomic variations concerning head and neck veins is important to surgeons performing interventions in these regions, as well as to radiologists. The retromandibular vein is used as a guide to expose the facial nerve branches inside the parotid gland, during parotid surgery and open reduction of mandibular condyle fractures. It is also used as a landmark for localisation of the nerve and compartmentalisation of parotid gland lesions preoperatively, during computed tomography, magnetic resonance imaging and sonography. In this paper, the anomalous retromandibular vein's course on the left side of a male cadaver is described. The vein was formed around the nerve, while the maxillary vein travelled medial to the facial nerve branches and superficial to the superficial temporal vein. Interestingly, the facial nerve temporofacial division crossed again the superficial temporal vein upwards, forming a "nerve fork". The incidence of the reported variability of the relationship between the retromandibular vein and the facial nerve are discussed with a detailed literature review. Accordingly, the typical deep position of the retromandibular vein in relation to the facial nerve is estimated to 88.17% to all sides. Furthermore, an updated classification system is proposed, including 4 types and subtypes.
