Anatomical variations and sinusitis.
Acta oto-rhino-laryngologica Belgica, 1997Paranasal sinus anatomy and variations have gained interest with the introduction of functional endoscopic sinus surgery and the concept of the ostiomeatal complex. Anatomical variations can be divided in structural abnormalities, (increased) pneumatization and supplementary openings.

Anatomical Variations of the Cystic Artery
European Journal of Morphology, 2003Thorough knowledge about the origin of the cystic artery is surgically important, especially when intraoperative or post-operative bleeding occurs in the gallbladder fossa. The arterial supply of the gallbladder was studied in 81 livers. The gallbladder was supplied by one cystic artery in 86% and by two arteries in 14% of cases.

Anatomic Variations of the Frontal Sinus
min - Minimally Invasive Neurosurgery, 2003Minimally invasive approaches are increasing in popularity. We have undertaken an anatomic and radiological study of the frontal sinus that is frequently involved in the supercilliary minicraniotomy used to access the parasellar region.We wanted to evaluate the prevalence and morphological characteristics of the frontal sinus in a certain population ...

Anatomical Variations of Nasal Turbinates
Journal of Craniofacial Surgery, 2008After the widespread use of endoscopic sinus surgery and paranasal sinus computed tomography, many variations of nasal turbinates have been described. In addition to the most common one-middle turbinate pneumatization (concha bullosa)-superior and inferior turbinate pneumatizations have also been described.

Anatomic variations in the tetralogy of Fallot
American Heart Journal, 1971Abstract Eighty-five specimens with a tetralogy of Fallot from patients varying in age from infancy to adult life were studied for (1) the nature of the pulmonary valve, the right ventricular infundibulum, the pulmonary arteries, the aortic arch, and the atrial septum and (2) the association of other anomalies and of bacterial endocarditis.

Anatomic Variations of the Nasolabial Fold
Plastic and Reconstructive Surgery, 1992The nasolabial fold varies considerably from person to person. Three main groups may be distinguished: convex, concave, and straight. It is the muscles of smiling that are directly responsible for the shape and depth of the fold, and in their absence of function, as in facial palsy, the nasolabial fold disappears.

Anatomic variations and stone formation
Current Opinion in Urology, 2018The pathophysiological mechanisms in kidney stone formation are insufficiently understood. In order to achieve a better understanding of the complexity of stone formation, studies evaluating anatomical variations in the renal papillae have been performed. This review intends to illuminate recent findings.

Pathologic Anatomic Variations in the Sesamoids
Foot & Ankle, 1981This paper reviews 26 patients who presented with disorders of one or both sesamoids of the foot. There is a high association between long-distance running and chondromalacia or stress fractures in these bones. Thirty-eight per cent of these patients had variations in the anatomy at this articulation, including asymmetry in sesamoid size, symmetrical ...

Anatomic variations of the midcarpal joint
The Journal of Hand Surgery, 1990Two distinct anatomic variations in the human midcarpal joint have been identified. In type I the triquetrohamate joint is on a smooth oblique plane with the capitolunate joint. In type 2 the triquetrohamate joint is separated from the capitolunate joint by a concave transition facet on the hamate and lunate.

The Female Knee: Anatomic Variations
Journal of the American Academy of Orthopaedic Surgeons, 2007Traditional knee implants have been designed "down the middle,"based on the combined average size and shape of male and female knee anatomy.Sex-based research in the field of orthopaedics has led to new understanding of the anatomic differences between the sexes and the associated implications for women undergoing total knee arthroplasty.
