Medial canthoplasty: early and delayed repair.

Naso-orbital trauma can cause medial orbital wall disruption and detachment of the medial canthal ligament. Damage to the nasolacrimal drainage apparatus, cerebrospinal fluid rhinorrhea and frontal sinusitis can occur. Twelve cases of naso-orbital trauma have been reviewed. There is a high incidence of associated injury to adjacent structures. Medial canthal ligament separation was missed acutely in a number of cases leading to the necessity of delayed repair. Important diagnostic and therapeutic points are stressed in the acute and delayed management, particularly medial canthal ligament separation. A wire to intranasal button technique for the delayed repair of traumatic telecanthus is presented.
