Medial canthoplasty: early and delayed repair
The Laryngoscope
|February 1, 1981
Summary
Naso-orbital trauma often injures surrounding structures, including the medial canthal ligament. Delayed repair is frequently needed when this ligamentous injury is missed acutely, impacting cosmetic and functional outcomes.
Area of Science:
- Ophthalmology
- Plastic Surgery
- Trauma Surgery
Background:
- Naso-orbital trauma can lead to medial orbital wall disruption and medial canthal ligament (MCL) detachment.
- Associated injuries to the nasolacrimal drainage, cerebrospinal fluid (CSF) rhinorrhea, and frontal sinusitis are common.
- Acute diagnosis of MCL separation is often missed, necessitating delayed surgical intervention.
Purpose of the Study:
- To review cases of naso-orbital trauma and highlight associated injuries.
- To emphasize the importance of diagnosing and managing medial canthal ligament separation.
- To present a technique for delayed repair of traumatic telecanthus.
Main Methods:
- Retrospective review of twelve cases of naso-orbital trauma.
- Analysis of associated injuries and diagnostic/therapeutic management strategies.
- Presentation of a wire-to-intranasal button technique for delayed MCL repair.
Main Results:
- A high incidence of associated injuries to adjacent orbital and facial structures was observed.
- Medial canthal ligament separation was frequently missed in the acute setting.
- Delayed repair was required in several cases due to missed acute diagnosis.
Conclusions:
- Prompt diagnosis and management of medial canthal ligament separation are crucial in naso-orbital trauma.
- Delayed repair of traumatic telecanthus can be effectively managed with techniques like the wire-to-intranasal button.
- Comprehensive evaluation for associated injuries is essential in all naso-orbital trauma cases.
