Anatomic Variations in the

Archives of Otolaryngology - Head and Neck Surgery, 1968
THERE ARE several anatomic variations in, or near, the oval window of the temporal bone of major significance to the otologic surgeon. The variants to be considered here are dehiscence of the fallopian canal adjacent to the oval window, distance of the utricle from medial surface of the stapedial footplate, and fibrous connections between the utricle ...

Anatomical variations of the sural nerve

Clinical Anatomy, 2002
AbstractAn anatomical study of the formation of the sural nerve (SN) was carried out on 76 Thai cadavers. The results revealed that 67.1% of the SNs were formed by the union of the medial sural cutaneous nerve (MSCN) and the lateral sural cutaneous nerve (LSCN); the MSCN and LSCN are branches of the tibial and the common fibular (peroneal) nerves ...

Anatomical Variation Of The Sphenomandibular Ligament

Australian Endodontic Journal, 2001
ABSTRACTThe sphenomandibular ligament, which is derived from the sheath of Meckel's cartilage, is a fibrous structure that passes between the spine of the sphenoid bone and the lingula of the mandible. Although anatomical texts provide basic descriptions of this structure, there are few published reports of the extent of its variability or its possible

Pancreatic Development and Anatomical Variation

Gastrointestinal Endoscopy Clinics of North America, 1995
The pancreas is formed by the fusion of the ventral and dorsal anlage, and a wide spectrum of anomalies or anatomical variations may appear related to this complicated process of fusion: e.g., agenesis, aplasia of a pancreatic anlage, hypoplasia, annular pancreas, pancreas divisum or nonfusion of the ventral and dorsal duct system, pancreaticobiliary ...

Anatomical Variations of the Cystic Artery

European Journal of Morphology, 2003
Thorough 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.

Anatomical Variations of Nasal Turbinates

Journal of Craniofacial Surgery, 2008
After 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 of the Frontal Sinus

min - Minimally Invasive Neurosurgery, 2003
Minimally 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 ...

Anatomic Variations of the Nasolabial Fold

Plastic and Reconstructive Surgery, 1992
The 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 in the tetralogy of Fallot

American Heart Journal, 1971
Abstract 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.
