Multimodal Management of Facial Keloid with Tissue Expansion, Excision, and Injection of 5-FU and Triamcinolone.

ABSTRACT: Keloids are benign, fibroproliferative dermal growths that occur in response to injury of the skin. These hypertrophic scars can cause pain and discomfort and have been associated with negative effects on social well-being, prompting physicians to seek effective treatment modalities with minimal risk of recurrence. Although surgical excision of the keloid initially removes the scar tissue, surgery alone triggers a fibroproliferative response similar to the initial insult, resulting in a high recurrence rate. Thus, a multimodal approach may be most appropriate when surgery is indicated to limit recurrence. We present the successful treatment of recalcitrant keloid formation of the face that was treated with tissue expansion, excision, and intralesional triamcinolone and 5-flurouracil injections.

Project description:BackgroundOne of the first-line options to treat keloid scars is corticosteroid injection after excision of the existing scar. A thorough literature search has shown a lack of research on the injection of corticosteroid injection immediately after the excision of the existing caesarean section keloid scars. Therefore, in the proposed study, we aim to investigate the effect of surgical excision and corticosteroid (triamcinolone acetonide) injection immediately after surgical removal of old caesarean section keloid scars on the recurrence of the scars. This is a protocol for a randomised controlled trial.Methods/designPregnant women (n = 150), who attend antenatal clinics at Westmead Hospital in New South Wales, Australia, have a keloid scar from a previous caesarean section, meet the inclusion criteria and sign the consent form, will be randomised to either the control or the intervention group. The control group will receive surgical excision of the keloid scar at the beginning of the procedure during skin incision. The baby will be delivered according to normal procedures, and routine wound closure will be performed in accordance with National Institute for Health and Care Excellence guidelines. The intervention group will receive surgical excision of the keloid scar after the delivery of the baby, and closure of the uterus layers, rectus sheath and the fat layer will be completed as explained above. Then, triamcinolone acetone will be injected sub-dermally at the time of wound closure. Two ampules of triamcinolone acetonide will be administered at a single dose; each ampule contains 10 mg/1 ml active medication. The surgeon will inject one ampule along the entire length of the upper edge of the skin incision and one ampule along the entire length of the lower edge of the skin incision, using a 25 G needle. After the procedure is completed, the surgeon will fill in the post-operation survey. The participants will be followed up post-operation, daily on the ward and then at 6 weeks, 6 months and 12 months post-partum. Main outcomes are (1) keloid formation after caesarean section and (2) changes in the appearance and specification of the keloid scar after the intervention.DiscussionWe anticipate that surgical excision and steroid injection will be a safe, lasting and cost-effective treatment in the management of caesarean keloid scars which will be useful for patients unable to undergo cosmetic surgery due to clinical or financial reasons.Trial registrationAustralian New Zealand Clinical Trials Registry, ACTRN12618000984291 .

Project description:SignificanceSpatial frequency domain imaging (SFDI) applies patterned near-infrared illumination to quantify the optical properties of subsurface tissue. The periocular region is unique due to its complex ocular adnexal anatomy. Although SFDI has been successfully applied to relatively flat in vivo tissues, regions that have significant height variations and curvature may result in optical property inaccuracies.AimWe characterize the geometric impact of the periocular region on SFDI imaging reliability.ApproachSFDI was employed to measure the reduced scattering coefficient ( μs' ) and absorption coefficient ( μa ) of the periocular region in a cast facial tissue-simulating phantom by capturing images along regions of interest (ROIs): inferior temporal quadrant (ITQ), inferior nasal quadrant (INQ), superior temporal quadrant (STQ), central eyelid margin (CEM), rostral lateral nasal bridge (RLNB), and forehead (FH). The phantom was placed on a chin rest and imaged nine times from an "en face" or "side profile" position, and the flat back of the phantom was measured 15 times.ResultsThe measured μa and μs' of a cast facial phantom are accurate when comparing the ITQ, INQ, STQ, and FH to its flat posterior surface. Paired t tests of ITQ, INQ, STQ, and FH μa and μs' concluded that there is not enough evidence to suggest that imaging orientation impacted the measurement accuracy. Regions of extreme topographical variation, i.e., CEM and RLNB, did exhibit differences in measured optical properties.ConclusionsWe are the first to evaluate the geometric implications of wide-field imaging along the periocular region using a solid tissue-simulating facial phantom. Results suggest that the ITQ, INQ, STQ, and FH of a generalized face have minimal impact on the SFDI measurement accuracy. Areas with heightened topographic variation exhibit measurement variability. Device and facial positioning do not appear to bias measurements. These findings confirm the need to carefully select ROIs when measuring optical properties along the periocular region.

Project description:BackgroundKeloid disease is hard to fully eradicate. Recurrence and other unsatisfactory results were found in many patients. No current therapeutic modality has been determined to be most effective for treating keloid scars. Intralesional corticosteroid injections is most commonly recommended for primary management of small and young keloids as well as hypertrophic scars. However, it's difficult for patients to adhere to long-term triamcinolone acetonide injection therapy because of the pain, inconvenience or complications including hormonal imbalance or irregular menstruation.ObjectiveWe aimed to determine whether and how Strontium-90 brachytherapy as an adjuvant radiation could affect keloid recurrence after intralesional triamcinolone and 5-fluorouracil injections.MethodsWe included keloid patients from March 2019 to September 2019 and randomly allocated them to two groups after 3 intralesional triamcinolone and 5-fluorouracil injections at 3 weeks interval. The experimental group received Strontium-90 brachytherapy at a total dose of 15-20Gy, while the control group didn't receive any adjuvant treatment. We performed both Vancouver Scar Scale scoring and Color Doppler ultrasound examination to monitor and evaluate lesions regularly. A one-year follow-up was completed for each patient.Results31 patients who had 42 keloids in total were recruited. We found intralesional triamcinolone and 5-fluorouracil injections could effectively reduce the thickness and modify the hardness of small and young keloids. Strontium-90 brachytherapy reduced the one-year recurrence rate from 85.7 percent to 44.4 percent after 3 intralesional triamcinolone and 5-fluorouracil injections. The lesions' thickness or elasticity was not affected by Strontium-90 brachytherapy.ConclusionStrontium-90 brachytherapy as an adjuvant radiation could effectively reduce small sized keloids recurrence after intralesional triamcinolone and 5-fluorouracil injections. It worked by enhancing the lesions' stability post-injection.Trial registrationThe clinical trial registration number: ChiCTR2000030141.
