Summary

Orbital decompression effectively reduces eye protrusion in dysthyroid orbitopathy for cosmetic reasons. Complications are rare and manageable, making it a viable option for disfiguring cases.

Area of Science:

  • Ophthalmology
  • Plastic Surgery

Background:

  • Dysthyroid orbitopathy causes progressive exophthalmos, leading to disfigurement and psychosocial distress.
  • Cosmetic concerns are increasingly accepted as a valid indication for orbital decompression surgery.
  • Traditionally, orbital decompression is reserved for cases threatening vision, despite cosmetic impacts.

Purpose of the Study:

  • To evaluate the efficacy and safety of orbital decompression for cosmetic indications in dysthyroid orbitopathy.
  • To assess the degree of exophthalmos reduction and complication rates in patients undergoing surgery for cosmetic reasons.

Main Methods:

  • Orbital decompression was performed on 34 patients (65 orbits) for cosmetic reasons between 1984 and 1990.
  • Patient charts were retrospectively reviewed to analyze surgical outcomes and complications.

Main Results:

  • A mean retroplacement of 4 mm was achieved, with 85% of patients having ≤1 mm difference in proptosis between eyes postoperatively.
  • New-onset diplopia occurred in 18% of patients, managed successfully with adjustable strabismus surgery.
  • No major surgical complications were observed, apart from transient infra-orbital nerve hypoesthesia.

Conclusions:

  • Orbital decompression is an effective surgical treatment for reducing exophthalmos in dysthyroid orbitopathy.
  • Complications associated with cosmetic orbital decompression are infrequent and treatable.
  • This procedure can be the initial step in a series of operations to correct cosmetic deformities, suitable for carefully selected patients.
