BACKGROUND: Treatments for solar lentigines include topical and physical therapies, including chemical peels, lasers, intense pulsed light, and cryotherapy. A direct comparison of treatment methods and their efficacy is lacking. OBJECTIVE: To compare treatment efficacy and adverse events for different treatment modalities for lentigines. METHODS: Cochrane, MEDLINE, and Embase databases were searched on August 25, 2021. Studies were included if they met our predetermined population, intervention, comparator, outcomes, study design framework. Results are presented in narrative form. RESULTS: Forty-eight articles met the inclusion criteria, representing a total of 1,763 patients. Overall, combination-based treatments showed the greatest frequency of cases with complete response (65%, n = 299/458), followed by laser-based treatments (43%, n = 395/910), topical retinoids (21%, n = 12/57), cryotherapy (15%, n = 25/169), and peels (6%, n = 8/125). Adverse events occurred most commonly while using topical retinoids (82%, n = 23/28), followed by combination-based treatments (39%, n = 184/466), cryotherapy (33%, n = 47/144), laser-based treatments (23%, n = 173/738), and peels (19%, n = 21/110). CONCLUSION: Despite heterogeneity of included study designs, patient populations, treatment regimens, and outcome measures, our results suggest that combination-based treatments and laser-based treatments were the most efficacious treatment modalities. Although cryotherapy was previously considered first-line, our results show that it has substantially lower pooled response rates compared with other treatment modalities. [ABSTRACT FROM AUTHOR]

BACKGROUND: Paramedian forehead flaps (PMFFs) are commonly used for reconstruction of nasal defects. The classic PMFF is vertically oriented while the modified PMFF is designed with a 90-degree angle. No study has compared outcomes between these PMFF designs. OBJECTIVE: To compare and quantify viability and cosmesis of 90-degree and vertical PMFF. METHODS: Retrospective chart review of 70 consecutive patients with a vertical or 90-degree PMFF design for nasal repairs after Mohs micrographic surgery (MMS). Cosmetic outcome was assessed on a 10-cm, 100-point, visual analog scale (VAS) by an independent observer using standardized 3-month postoperative photographs. Flap viability was assessed using standardized 3-week postoperative photographs. Descriptive statistics, t -test, and Mann–Whitney test were used for statistical analysis. RESULTS: Forty-eight patients were repaired with a vertical PMFF and 22 using the 90-degree PMFF. The mean defect area of vertical and 90-degree designs was equivalent (7.7 ± 4.0 cm2 vs 8.1 ± 4.0 cm2, p =.70). There was no significant difference in cosmetic outcome (75.9 ± 9.4 vs 72.9 ± 6.8, p =.19) or flap viability (3.8% ± 11.6 vs 2.6% ± 7.9, p =.67) between vertical and 90-degree designs. CONCLUSION: Vertical and 90-degree PMFF designs for nasal repairs after MMS are equivalent in cosmetic outcome and viability. [ABSTRACT FROM AUTHOR]
