It is usually in the medial canthus
of the eye [3, 5]; it may be isolated  or in association with other craniofacial anomalies [3, 4, 6].
Starting at the lateral canthus
a line is drawn with a semicircular pattern towards the lateral eyebrow.
the GE Voluson E8 Ultrasound Scanner (GE Healthcare, USA) was used for the check, when the complete eyeball echo was obtained, the probe should be moved slowly towards the medial canthus
, during which period, the probe scanning tangent was kept vertical with the eyelid, when the ultrasonic probe found the lacrimal sac, made it stay in the center of screen, and adjusted the depth, pulse repetition frequency, focus area and sampling volume based on individual circumstances so that it could cover the full width of LSC; labeled the probe position, and pressed the 3D button, kept the probe stable, and pressed the freezing button for the automatic acquisition of 3D volumetric ultrasonic data, the data were stored in the hard disk for the later processing.
Evaluation of recurrent BCC cases in the literature reveals that tumors of the morpheaform subtype and those located in the medial canthus
are particularly prone to recurrence.
In addition, the small flap is well hidden in the lateral canthus
and associated with a natural appearance.
Statistically significant differences were observed between the study and control groups in all day 2 measurements (tragus-comissuralabiorum, gonion-comissurelabiorum, gonion-lateral canthus
Then two chains were applied over the forelimbs and a hook inserted in the medial canthus
of eye to pull the fetus.
Stab incisions were made in the lid approximately 2 mm from the lid margin to avoid the lash roots and are made just lateral to the upper punctum and approximately 3 mm from the lateral canthus
. Brow incisions were made at a position in line with the medial and lateral canthi.
She reported associated discomfort from frontal pressure and pain in the area of the right medial canthus
. She denied any symptoms of hyposmia.
For difficult areas such as those involving the medial canthus
or the eyelids, the flap was rotated toward the defect for repair of the medial canthus
, anterior lamella of the lower eyelid, and the side of the nose.
The lesions were located in lower lid, inner canthus
, upper lid, and outer canthus
12 (57.1%), 7 (33.3%), 1 (4.8%), and 1 (4.8%), respectively (Table 2).
