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 cm 2 vs 8.1 ± 4.0 cm 2 , 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.
