Currently, different surgical procedures have been developed for nasal dorsum reconstruction; among them, techniques may include autologous soft tissue grafts (temporal fascia) and autologous cartilage. Objective: To determine a viable alternative that preserves nasal dorsum augmentation using a soft implant filled with chopped cartilage in patients with mild to moderate post-traumatic osteocartilaginous dorsum subsidence. The technique of sliced cartilage on costal perichondrium is used because it avoids resorption of the sliced grafts over time. Materials and methods: The study was performed in a clinic in Lima, Peru, during the year 2022 to 2023. Twenty cases of patients between the ages of 20 to 45 years who underwent nasal dorsum augmentation with chopped cartilage removed from the costal cartilage participated. The patients were evaluated at the third, sixth month and one year post reconstruction. Results: It was observed that the combination of the MIXING GRAFT technique, where cut autologous cartilage plus costal perichondrium is used, was demonstrated in the measurements of nasion, rhinion and supraspinatus of each patient manifesting constant heights in contrast to the separate cut graft technique, which resulted in a significant decrease in the height of the nasal dorsum. Conclusions: The use of the MIXING GRAFT technique provides more durable and constant results in the three evaluated points, nasion, rhinion, supraspinatus. Therefore, its use is recommended as an alternative to correct posttraumatic nasal dorsal dorsum subsidence.
