This study shows that a customized, single-incision, 3-wall orbital decompression effectively reduces proptosis and improves vision. The procedure offers good cosmetic results with minimal complications for patients with thyroid eye disease.

Area of Science:

  • Ophthalmology
  • Plastic Surgery
  • Endocrinology

Background:

  • Thyroid eye disease (TED) often causes proptosis (bulging eyes) and compressive optic neuropathy, impacting vision and aesthetics.
  • Orbital decompression surgery aims to alleviate these symptoms by increasing the orbital volume.
  • Customized surgical approaches are crucial for optimizing outcomes in orbital decompression.

Purpose of the Study:

  • To evaluate the clinical outcomes of a customized, single-incision, 3-wall orbital decompression technique.
  • To assess the efficacy of this approach in reducing proptosis and improving visual function.
  • To determine the procedure's impact on diplopia and aesthetic results.

Main Methods:

  • A retrospective review of 97 orbital decompressions in 55 consecutive patients undergoing a standardized single-incision, 3-wall decompression.

  • Surgical technique involved a lateral small incision with preservation of specific orbital struts.
  • Outcomes measured included proptosis reduction (Hertel exophthalmometry), visual acuity, color vision, diplopia, and extraocular muscle function.

    • Main Results:

    • An average proptosis reduction of 5 mm was achieved at 3 months post-surgery.
    • Visual acuity improved by an average of 2 Snellen lines in patients with compressive optic neuropathy.
    • Color vision improved by an average of 5 Ishihara plates; 21% of patients with preoperative diplopia experienced improvement or resolution.

    Conclusions:

    • Customized, single-incision, 3-wall orbital decompression is an effective method for reducing proptosis and improving visual acuity.
    • The technique minimizes postoperative strabismus and yields aesthetically pleasing results.
    • This approach offers a safe and effective solution for managing the disfiguring and visually impairing effects of proptosis.
