Background: Dorsal augmentation is one of the most challenging procedures in rhinoplasty. Solid grafts and diced fascia graft (DC-F) have been employed for this purpose with varying success. Warping, irregularities, and variability of final height are some of the potential pitfalls. Objectives: The aim of this study was to assess the efficiency of the authors' approach combining multiple grafts for nasal dorsal augmentation. They described a technique employing composite dorsal augmentation that is a combination of a foundation layer utilizing high spreader grafts plus a dorsal gap graft combined with a contour layer of 3 possible types of fascia or DC-F grafts. The combination of the 2 layers for the nasal dorsum can be varied to achieve the required height to correct the patient's deformity and achieve the desired aesthetic goals. Methods: Fifty-one patients who underwent dorsal augmentation with composite technique between 2017 and 2020 were retrospectively reviewed. A step-by-step algorithm was applied to achieve the required dorsal height. Results: The patients were divided into 3 groups according to the type of contour graft: double-layer fascia graft, segmental DC-F, or narrow thin full-length DC-F. Smooth continuity and increased projection of the nasal dorsum were achieved in all patients. Conclusions: Composite dorsal augmentation is an effective technique for dorsal augmentations requiring 4 mm or more of height increase. This technique allows to achieve dorsal augmentation employing a combination of grafts from a single donor site together with camouflaging dorsal irregularities and highlighting dorsal aesthetic lines. This algorithm allows optimization of patients' aesthetic profile.
