Endoscopic transnasal orbital decompression offers a less invasive alternative for dysthyroid orbitopathy, achieving comparable results to traditional surgical methods. This approach reduces surgical morbidity while effectively decompressing the orbit.

Area of Science:

  • Ophthalmology
  • Otorhinolaryngology
  • Neurosurgery

Background:

  • Dysthyroid orbitopathy (DO) management often involves orbital decompression.
  • Traditional methods include external and transantral approaches.
  • Endoscopic intranasal techniques offer a minimally invasive alternative.

Observation:

  • Thirteen orbits in eight patients with severe DO underwent transnasal decompression.
  • Combined procedures included lateral orbitotomies (5 patients) and Walsh-Ogura decompressions (2 orbits).
  • Hertel measurements assessed orbital decompression efficacy.

Findings:

  • Transnasal decompression, alone or combined with lateral orbitotomy, significantly reduced Hertel measurements (average 4.7 mm and 5.7 mm, respectively).
  • Walsh-Ogura decompression with lateral orbitotomy showed an average Hertel improvement of 4.5 mm.

  • Visual acuity improved in patients with optic neuropathy and exposure keratopathy.

    • Implications:

    • Endoscopic transnasal approach provides effective orbital decompression comparable to traditional methods.
    • This technique avoids the morbidity associated with external ethmoidectomy or Caldwell-Luc antrotomy.
    • It represents a valuable, less invasive surgical option for managing severe dysthyroid orbitopathy.
