Abstract:
INTRODUCTION
Epidermal inclusion cysts require surgical intervention to prevent recurrence and symptoms. Elliptical excision is definitive but results in longer scar, while minimal incision techniques offer better cosmetic outcomes despite higher recurrence rates probably due to incomplete excision. To date, there are currently no local studies published.
METHODOLOGYA randomized controlled trial was conducted from October 2023 to May 2024 at a dermatology center in the Philippines. Patients were randomly assigned to minimal incision or elliptical excision techniques. Key metrics included operation time, scar length, post-operative complications, Hollander wound evaluation score (HWES), and histopathological completeness of excision.
RESULTSMedian operation duration was 31.86 minutes, with no significant difference between techniques (p = 0.5795). Post-operative scars were longer in the excision group (mean: 2.38 ± 0.66 cm) versus the minimal incision group (p < 0.001). Completeness of excision was higher in the excision group (83%) compared to the minimal incision group (27%) (p = 0.0123). Follow-up scar length was shorter in the minimal incision group (mean: 0.44 ± 0.21 cm) versus the excision group (mean: 2.1 ± 0.63 cm) (p < 0.001). HWES scores showed no significant difference in wound healing and aesthetic satisfaction.
CONCLUSIONMinimal incision technique results in shorter scars but lower completeness of excision compared to elliptical excision. Both techniques have similar long-term outcomes in wound healing and aesthetic satisfaction, with no recurrences or complications beyond two weeks. The choice should balance scar length and completeness of cyst removal, considering patient-specific factors.
