Pilot study evaluating topical onion extract as treatment for postsurgical scars.
BACKGROUND Post surgical scars can be erythematous , raised , pruritic and painful . Numerous modalities are available to improve the appearance and symptomatology of these scars . A topical onion gel extract is the newest in the armamentarium of scar treatments . The active ingredient in this gel is allium cepa . Published studies evaluating the usefulness of this gel in the treatment of scars are not available . OBJECTIVE To evaluate the effectiveness of topical onion gel extract in improving the appearance and symptomatology of postsurgical scars and to compare the results of its use to those of a topical emollient ointment . METHODS Seventeen patients with surgical scars result ing from Mohs surgery  were assigned to 1 of 2 groups on the day of suture removal . Each group applied a design ated topical product 3 times a day for 1 month . Photographic documentation and question naires using a visual analog scale were completed for each scar enrolled in the study . RESULTS Using the Fischer 's exact test , no statistically significant difference between pre- and posttreatment evaluations of scar erythema and pruritus in patients using topical onion extract gel was found . A statistically significant reduction in scar erythema was found in patients using a petrolatum based ointment . CONCLUSIONS Scar hydration is an important factor in wound healing and can be achieved with topical petrolatum-based ointment . Topical onion gel extract was ineffective in improving scar erythema and pruritus in our patients
