The Z-plasty has two major uses: correction of a retracted lip or medial canthus
Brachycephalic breeds such as Pugs and Bulldogs develop entropion at the medial canthus
of the eyelid (near the nose).
After complete removal of affected eye, opening was left open on medial canthus
in all animals for daily dressing with Povidone iodine seton (Fig.
The distance between the medial canthus
of the eyes was measured for inner canthal distance and interproximal contacts were used as reference points for measuring the width of central maxillary incisors.
Malignant hidradenoma of the medial canthus
with orbital and intracranial extension.
It has been demonstrated that the lower eyelid lymphatics drain into the submandibular glands  and the upper eyelid and medial canthus
lymphatics drain into the parotid lymph nodes .
A baby girl aged seven months presented to our clinic, Etomie Oral and Maxillofacial Clinic, Kaduna, Kaduna State, Nigeria, with a thick tubular structure in the medial canthus
of the left eye and cleft of the left upper lip, left alveolus, and primary and secondary palates from birth.
A 75-year-old male, retired personnel, presented with complaints of swelling at medial canthus
of the left eye of one-year duration associated with pain, ocular discharge, redness, and watering.
The study indicates that medial canthoplasty combined with CDCR surgery rebuilds normal appearance of eyelid and contour of the medial canthus
and successfully repairs the function of the lacrimal drainage system.
The operative procedure starts with an incision at the border between the nasal sidewall and the cheek from the medial canthus
to nasal ala.
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.
