Orbital Exenteration
Orbital exenteration is a radical surgical procedure used to treat advanced conjunctival melanoma when the cancer has spread beyond the conjunctiva into deeper orbital tissues. While it is a life-saving measure, it is also physically and emotionally impactful. Here’s a comprehensive guide to what you can expect:
1
When is Exenteration Recommended?
Orbital exenteration is typically considered when:
- The melanoma invades deep tissues of the orbit.
- There is recurrence after multiple prior treatments.
- Tumor margins are not controlled with conservative surgery or radiation.
- There’s a high risk of extraocular extension or metastasis.
2
Preoperative Evaluation and Planning
Imaging and Staging
- High-resolution MRI or CT scans evaluate the extent of orbital invasion.
- A PET-CT or other systemic workup rules out distant metastasis.
Multidisciplinary Discussion
- Your case may be reviewed by a team including:
- Ocular oncologists
- Oculoplastic surgeons
- Radiation and medical oncologists
- Psychologists or social workers
Counseling and Consent
- You will receive counseling on:
- Functional loss (loss of vision, eye, eyelid, and orbital tissues)
- Cosmetic changes
- Reconstructive options
- Emotional and psychological impact

The Surgery Itself
Procedure Overview
- Performed under general anesthesia.
- Varies in extent depending on the tumor:
- Total Exenteration: Removal of the eye, eyelids, and orbital contents.
- Subtotal or Modified: May spare eyelids or skin, if uninvolved.
- The conjunctival melanoma and surrounding tissues are excised en bloc.
Orbital Reconstruction
- A temporary or permanent skin graft, muscle flap, or dermal matrix is used to cover the orbital cavity.
- A conformer shell may be placed to preserve orbital volume.

Recovery and Healing
Immediate Postoperative Period
- Hospital stay of several days may be required.
- Pain, swelling, and drainage from the wound are expected.
- Antibiotics and pain medication are prescribed.
Wound Care
- Dressings are changed regularly.
- Healing typically takes several weeks.
- You may be fitted with a custom orbital prosthesis once the socket is fully healed.
5
Rehabilitation and Reconstruction
Facial Prosthesis (Epithetic Eye)
- Crafted by a maxillofacial prosthetist.
- Designed to blend with your facial features.
- Attached with glue, magnets, or implants embedded in bone.
Alternative Reconstructive Options
- Some patients may opt for skin flaps or tissue expanders for surgical reconstruction rather than a prosthetic.
6
Risks and Long-Term Side Effects
Physical Side Effects
- Altered facial structure.
- Risk of wound infection or flap failure.
- Dryness or discharge from the orbital cavity.
Emotional and Psychological Impact
- Grief, depression, or anxiety are common reactions.
- Supportive counseling is highly recommended.
- Appearance-related concerns can be addressed with prosthetics or reconstructive surgery.
7
Ongoing Monitoring and Prognosis
Surveillance
- Regular follow-up to:
- Monitor for local recurrence
- Conduct systemic scans for metastasis (esp. lymph nodes, lungs, liver)
- Frequency depends on tumor aggressiveness but may begin every 3–6 months.
Adjuvant Therapy
- Radiation therapy may be given postoperatively if margins are close or involved.
- Immunotherapy or targeted therapy may be considered in metastatic disease or in clinical trials.
8
Quality of Life
- Despite the physical loss, many patients regain confidence and resume active lives with proper support.
- Patient groups and organizations (such as A Cure In Sight) offer emotional and practical resources.
