Refining laissez-faire treatment of periocular tumor defects by exploring the impact of defect localization and geometry on the healing process

Purpose
This study examines periocular tumor defects treated with the laissez-faire approach, focusing on how defect geometry and location affects wound contraction and healing outcomes.
Methods
46 patients undergoing laissez-faire treatment for periocular tumor defects were included. Defects were categorized into medial canthal defects (n=10), proportional (n=21) and disproportional lower eyelid defects (n=7), based on the proportion of anterior and posterior lamellae excised. Cases requiring extended excisions due to non-radical margins (n=8) were analyzed as a separately. Wound contraction was assessed through serial photography after 1 week, 3 weeks, 6–8 weeks, and 5 months to 2 years. Defect size was standardized using corneal area measurements.
Results
Proportional lower eyelid defects exhibited predictable healing, with rapid wound contraction the first 6–8 weeks and minimal complications. Disproportional defects showed uneven healing, resulting in ectropion or significant tissue loss in 6 of 7 cases. Medial canthal defects generally healed well, but larger defects (>50% of corneal area) took longer to contract and were associated with traction-related complications in isolated cases. Extended excisions were associated with a higher prevalence of complications, including ectropion, entropion and residual defects.
Conclusion
Defect geometry is crucial in the healing process and clinical outcomes of periocular defects treated with laissez-faire. Medial canthal defects and proportional lower eyelid defects heal more reliably, while disproportional and large medial canthal defects, as well as cases requiring extended excisions, pose a higher risk of complications. These findings emphasize the importance of careful patient selection and defect analysis to optimize outcomes.
