The sublabral sulcus can occur anywhere in the labrum, but it most commonly appears posteroinferiorly (48%) or anterosuperiorly
(44%), followed by posterosuperiorly (4%) and anteroinferiorly (4%).
Defined as the most medial compartment of the femoral sheath, the femoral canal is bordered anterosuperiorly
by the inguinal ligament, medially by the lacunar ligament, laterally by the femoral vein, and posteriorly by the pectineal ligament .
It arises below the nerve to the stapedius and traverses anterosuperiorly
via the posterior canaliculus, usually accompanied by the posterior tympanic branch of the stylomastoid artery.
Next, the posterior meatotomy incision is extended anterosuperiorly
upto 10 O'clock position in the left ear or 2 o'clock position in the right ear (Fig.
Instead, the device was positioned anterosuperiorly
in a nearly vertical position (figure 1, B).
The labral recess is found in the superior labrum (11 to 1 o'clock position) (Kreitner et al 1998, Pfahler et al 2003), whereas the sublabral foramen is located anterosuperiorly
(1 to 3 o'clock) (Rao et al 2003).
According to the Subaxial Cervical Injury Description System (SCIDS), bilateral facet dislocation is defined as a disruption of both facet joints in which the inferior articular processes of the cranial vertebra have translated anterosuperiorly
over the superior articular processes of the caudal vertebra.
It extended inferiorly to the right infratemporal fossa, posteriorly to the petrous bone close to the right carotid canal, inferomedially to the right parapharyngeal space, medially to the right lateral nasal wall, anterosuperiorly
to the right orbit through the inferior orbital fissure, superoanteriorly compressing the right optic canal and superoposteriorly to the sphenoid bone.
CT demonstrates a solitary midline mass located anterosuperiorly
to the vesical dome, which may be solid, cystic or mixed.
A well-defined, noncalcifled, large cystic lesion with heterogeneous echogenicity was demonstrated in the pelvis posterior to the bladder, displacing It anterosuperiorly
Once the proximal femur had been reamed, it was dislocated anterosuperiorly
, and the acetabulum was exposed with the aid of an inferior curved retractor.
The anterior wall is formed by the frontal process of maxilla and the frontal bone, which thickens anterosuperiorly
to form the frontal beak.
