Summary
Transorbital decompression surgery effectively treated orbital disfigurement and optic neuropathy in 19 patients. The procedure offered significant proptosis reduction and vision improvement with minimal permanent complications.
Area of Science:
- Ophthalmology
- Plastic Surgery
- Orbital Surgery
Background:
- Orbital decompression is a surgical procedure to reduce the volume of the orbital cavity.
- Indications include cosmetic disfigurement and optic neuropathy due to conditions like thyroid eye disease.
- Traditional approaches may involve multiple incisions and risks of complications.
Observation:
- A transorbital approach using a modified blepharoplasty incision was employed for orbital decompression.
- The study included 19 orbits, addressing cosmetic disfigurement and optic neuropathy.
- Surgical retroplacement averaged 5.2 mm in cases of disfigurement.
Findings:
- Vision improved to 20/40 or better in four out of five eyes with optic neuropathy.
- Complications were infrequent, including transient and one permanent case each of strabismus and infraorbital hypesthesia.
- The technique demonstrated a large reduction in proptosis.
Implications:
- The transorbital approach offers a single incision with wide exposure for orbital decompression.
- Preservation of the lateral orbital rim and canthal tendon is a key advantage.
- This method presents a favorable safety profile with a low incidence of permanent strabismus.
