Summary
Small margin excision (up to 2 mm) is effective for periocular basal cell carcinomas (BCCs). This approach shows a low recurrence rate, comparable to conventional methods, making it a safe alternative.
Area of Science:
- Ophthalmology
- Dermatology
- Oncology
Background:
- Periocular basal cell carcinomas (BCCs) are common skin cancers.
- Conventional excision often involves wider margins, potentially leading to larger defects.
Purpose of the Study:
- To evaluate the efficacy and safety of small margin (≤2 mm) excision for primary, well-defined periocular BCCs.
Main Methods:
- Retrospective analysis of 90 patients with periocular BCCs.
- Tumors excised with margins up to 2 mm.
- Delayed reconstruction for defects requiring flaps/grafts.
Main Results:
- Complete excision achieved in 86.7% after one excision, rising to 92.2% after two.
- Overall recurrence rate was 3.3% (3/90) over a mean follow-up of 47.5 months.
- Recurrence rate is comparable to conventional excision techniques.
Conclusions:
- Small margin excision is a safe and effective method for well-demarcated periocular BCCs.
- This technique offers a viable alternative to wider excisions, especially where Mohs surgery is unavailable.
