Summary

Endoscopic endonasal orbital decompression offers a scarless approach for endocrine ophthalmopathy. This technique achieves results comparable to traditional methods, improving vision and proptosis without external incisions.

Area of Science:

  • Ophthalmology
  • Otorhinolaryngology
  • Neurosurgery

Background:

  • Endocrine ophthalmopathy often necessitates orbital decompression when conservative treatments fail.
  • Surgical decompression aims to alleviate vision loss, strabismus, and keratopathy.
  • Traditional surgical approaches carry risks such as external scarring and Caldwell-Luc antrotomy morbidity.

Observation:

  • This study evaluates endoscopic-controlled endonasal orbital decompression in 6 patients.
  • The technique involves ethmoidectomy, medial/inferior orbital wall removal, and orbital fat herniation.
  • Indications include vision loss, visual field defects, strabismus, and severe keratopathy.

Findings:

  • Endoscopic decompression resulted in an average 3-4 mm reduction in proptosis (Hertel measurements).

  • All patients experienced improved visual acuity post-surgery.
  • Ocular motility improved or remained stable in most patients; two experienced increased diplopia.

    • Implications:

    • Endoscopic endonasal orbital decompression provides an effective, scarless alternative to traditional methods.
    • This minimally invasive approach yields comparable outcomes to extranasal and transantral procedures.
    • The technique avoids the disadvantages associated with conventional surgical routes.
