Repair of Traumatic Telecanthus
Updated July 2024
Surgical goals
- Primary: to restore the normal contour and function of the medial canthus following trauma
- Secondary — repair of
- associated orbital fractures and enophthalmos
- nasal deformities
- if injury present
- lacrimal drainage system
- frontal sinus
Indications and contraindications
- Indications
- Lateral displacement of medial canthus (telecanthus)
- Indications for associated procedures
- enophthalmos
- flattening/widening of nasal bridge or nasal telescoping
- epiphora
- frontal sinus dysfunction
- Contraindications
- Any contraindication to general anesthesia
- Particularly consider risks from trauma to the cribriform plate and CSF leak
Preoperative evaluation
- Patient History
- Mechanism of injury
- Previous procedures: Patients with traumatic telecanthus often present for secondary repair or revision after previous surgery.
- Patient concerns, symptoms
- enophthalmos
- epiphora
- breathing difficulty, sinus issues
- Clinical examination
- Assess degree of facial asymmetry, telecanthus, and enophthalmos (exophthalmometry).
- Evaluation of external nose, nasal septum, airway.
- Examine lacrimal drainage system if symptomatic or radiologic evidence of compromise.
- Review studies: CT orbits or maxillofacial
- Consider neurosurgical evaluation for frontal sinus injuries.
Surgical techniques
Transnasal wiring
- Surgical access — incisions
- bicoronal
- gingivobuccal sulcus
- transconjunctival/caruncular
- Lynch
- DCR
- Can also use previous scars/incisions
- Y to V epicanthoplasty can be helpful as a point of access and in correcting webbing
- 3 anatomic subgroups must be addressed
- Medial canthus
- Identify bone fragment with attached medial canthal tendon.
- Free bone with osteotomies and reposition medially.
- Place 2 drill holes posteriorly to insertion of medial canthal tendon and pass 28-gauge wire from temporal to nasal through both holes,
- Pass wires transnasally with awl and fixate to plate in supratrochlear region of contralateral orbit.
- If the bone fragment is too small or the tendon has been stripped from the bone (Class II and III injury, respectively), purchase the medial canthus tendon with a figure-8 of 28-gauge wire and pass as above.
- Place compression plates at the conclusion of repair to maintain medial canthal position and prevent hematoma formation.
- Address the medial canthus anatomic subunit last.
- Nose
- Correct nasal width by infracturing nasal pyramid with or without osteotomy and repositioning central maxillary buttress.
- Restore nasal dorsum height and length with bone grafts.
- Medial wall, orbital floor
- Dissect subperiosteally to identify fracture.
- Reposit prolapsed soft tissue.
- Place orbital implant of choice based on surgeon preference, size of defect, and available support.
Microplate fixation
- Cantilevered miniplate fixation
- Cantilever Y-shaped titanium miniplate from lateral nose
- Direct posteriorly into orbit.
- Fixate bone fragment with medial canthal tendon to plate.
Postoperative care and follow-up
- Routine postoperative care with addition of nasal precautions
- Avoid nose blowing.
- Avoid sucking through a straw.
- Compression plates left for at least 1 week
- Medications
- Analgesia with opiate-acetaminophen combination
- Broad-spectrum antibiotic to cover nasal and sinus flora, e.g., Augmentin
Complications
- Persistent telecanthus
- Epiphora/damage to nasolacrimal system
- Must handle medial canthal tissue carefully
- Low threshold for silicone stent placement
