An otherwise healthy 18-year-old woman presented to the Vanderbilt University Medical Center (VUMC) in 1996 with an 18-month history of a slowly enlarging mass in the area of the right medial canthus.
1) An important consideration is that in some cases, even a minimal amount of dissection of the central fragment performed to accommodate a single microplate hole and screw is enough to weaken the medial canthal tendon to the point that it cannot support the medial canthus and the lower eyelid structures; even with transnasal wiring of the fragment, as suggested by Markowitz, (1) the tendon would be too unstable to provide proper support.
Because the anatomic reduction appeared to preserve the intercanthal distance and the fractured segments, and given the preoperative stability of the medial canthus bilaterally, we felt that the medial canthus did not require a formal transnasal canthopexy.
Postoperatively, we noted that the medial canthus was inferiorly and anteriorly displaced.
A 58-year-old white man came to the otolaryngology department with a 48-hour history of left medial canthus edema and erythema, which had eventually spread across the entire periorbital region.
The periorbital swelling, erythema, and tenderness were more marked over the medial canthus and the frontal sinus on the left.
In addition, the tender red swelling extended from the left medial canthus over the glabella to the right medial canthus.
Although there was a higher rate of recurrence of lesions in the areas of the nose, medial canthus, and lips than elsewhere, the differences were not statistically significant.
