A comparison of postoperative outcomes based on recipient vessels in scalp free flap reconstruction: A systematic review and meta-analysis.

PURPOSE: The superficial temporal artery (STA) and facial artery (FA) are two commonly used recipient vessels when performing free tissue transfer to the head and neck. This meta-analysis compares the impact of recipient vessel location on free flap outcomes in scalp reconstruction. METHODS: A systematic review was conducted following PRISMA-P guidelines using six databases. Studies reporting free tissue transfer using the STA or FA as a recipient vessel for reconstructing scalp defects were included. Outcomes of interest included flap loss, partial flap necrosis, wound dehiscence, venous thrombosis, and infection rates. Quality evaluation was performed using ASPS criteria and the ROBINS-I tool. RESULTS: Of 3270 identified articles, 12 were included for final analysis. In total, 125 free flaps were identified (75 STA, 50 FA). Pooled analysis demonstrated an overall flap survival rate of 98.4% (STA 98.7% vs. FA 98.0%; p = .782). The mean defect size was significantly greater for flaps using the STA compared with the FA (223.7 ± 119.4 cm2 vs. 157.1 ± 96.5 cm2, p = .001). The FA group had a higher incidence of wound dehiscence than the STA group (14.0% vs. 1.3%, p = .005). However, meta-analysis demonstrated no significant difference in rates of wound dehiscence, flap loss, partial flap necrosis, venous congestion, or postoperative infection between groups. CONCLUSION: This is the first systematic review and meta-analysis to assess recipient vessel selection in scalp reconstruction. Our results do not support a single vessel as the superior choice in scalp reconstruction. Rather, these findings suggest that the decision between using the STA or FA is multifaceted, requiring a flexible approach that considers the individual characteristics of each case. Further research is needed to explore additional factors influencing recipient vessel selection, including defect location, radiation therapy, and prior head and neck surgery.

The Evolution of Unilateral Cleft Lip Repair.

ABSTRACT: The understanding of cleft lip etiology and approaches for surgical repair have evolved over time, allowing for improved ability to restore form and function. The variability of cleft lip presentations has necessitated a nuanced surgical approach with multidisciplinary cleft care. The earliest documentation of unilateral cleft lip repair predates the 19th century, with crude outcomes observed before the advent of curved incisions and advancement flaps. In the 20th century, straight line, quadrilateral flap, and triangular flap repairs were introduced to mitigate post-repair surgical scarring, increase lip length, and restore the symmetry of the Cupid's bow. Towards the latter part of the century, the development of rotation-advancement principles allowed for improved functional and aesthetic outcomes. Future technical improvements will continue to address the goals of lip and nasal symmetry, muscular continuity, precise scar concealment, and improved patient satisfaction in an increasing range of cleft phenotypes and during subsequent years of growth.
