Are there complications after surgery for basal cell carcinoma near the eyes?
Surgery near the eyes for basal cell carcinoma (BCC), the most common type of skin cancer, can cause complications, but most are minor and temporary. A 2024 review of 194 patients who had surgery near the eye found that serious problems were rare, and most people kept full eyelid function and had good cosmetic results 5. The most common issues were healing problems and eyelid changes, along with symptoms like eye irritation and pain 5.
What the research says
The largest source on this exact question is a retrospective review of post-Mohs reconstruction for cancers around the eye. In that study, the most common cancer was basal cell carcinoma (70.6%), and the most common location was the lower eyelid (56.7%) 5. There were no complications during surgery itself. After surgery, the most common problems were healing issues (6.7%) and ectropion (6.2%), which is when the eyelid turns outward. Patients also reported eye irritation (23.2%) and pain (20.1%). Despite these issues, most patients had full eyelid function (93.3%) and acceptable cosmetic appearance (94.8%) 5.
A Swedish study of Mohs micrographic surgery (a precise technique that removes cancer layer by layer) for periocular BCC looked at long-term outcomes. It found that recurrence happened in 5.4% of cases after an average of 37 months, and all recurrences were in patients who already had a recurrent tumor before surgery 7. This suggests that surgery near the eye can work well even for difficult cases, but careful removal of all cancer cells is important 7.
Other treatments for BCC near the eye have their own complication profiles. Cryosurgery (freezing the tumor) is described as safe with relatively few side effects. The main temporary problems are pain during or shortly after treatment, blistering, and local swelling. The most common long-term issue is lightening of the skin in the treated area or darkening around it 6. A study of diode laser ablation for facial BCC found that complications and outcomes were recorded, but the abstract does not give specific complication rates 8.
It is worth noting that the sources do not compare complication rates between different surgical techniques for periocular BCC in a head-to-head way. The evidence comes mostly from single-center reviews, which may not reflect every practice setting 57.
What to ask your doctor
- What are the specific risks of surgery in my case, given the exact location and size of my basal cell carcinoma?
- How often does your practice see complications like ectropion, healing problems, or eye irritation after this type of surgery?
- What signs after surgery should prompt me to call you right away?
- If I have had a basal cell carcinoma removed before, does that change my risk of complications or recurrence?
- What are the alternatives to surgery for my lesion, and how do their complication rates compare?
