Transethmoid-sphenoid optic canal decompression safely treats acute optic nerve trauma from head injuries. This surgical approach improved vision in 11 of 14 patients, including those with severe pre-operative vision loss.

Area of Science:

  • Ophthalmology
  • Neurosurgery
  • Trauma Surgery

Background:

  • Blunt head trauma can cause acute, unilateral optic nerve injury.
  • Optic nerve decompression is a potential treatment for vision loss after trauma.
  • The transethmoid-sphenoid approach offers access to the optic canal.

Observation:

  • Fourteen patients with acute optic nerve injury post-head trauma were studied.
  • All patients underwent ipsilateral external ethmoidectomy for optic canal decompression.
  • Perioperative dexamethasone treatment was administered to all participants.

Findings:

  • The transethmoid-sphenoid optic canal decompression procedure resulted in no observed morbidity or mortality.
  • Eleven out of fourteen patients experienced improved vision following the intervention.

  • Significant visual recovery was noted in 3 patients who were initially unable to perceive light.

    • Implications:

    • Transethmoid-sphenoid optic canal decompression is a safe and effective surgical option for indirect optic nerve trauma.
    • This minimally invasive technique can restore vision in patients with traumatic optic neuropathy.
    • Further research should explore long-term outcomes and patient selection criteria for this procedure.
