Augmentation of the Nasal Dorsum Using the Multi-stripped Autologous Cartilage Technique (MACT).

Nasal augmentation is a popular modern technique requested by many Asian people.There are two kinds of autologous cartilage used to augment the nose at present: carved as a monobloc or diced into pieces. Each approach has its pros and cons.We performed our surgical technique on a group of 28 patients. Twenty of these patients had had several rhinoplasties performed before referral to our hospital; 8 of these patients had undergone a primary rhinoplasty. bilateral conchal, nasal septum, or rib cartilage were harvested, deep temporal fascia or abdominal muscle fascia to be prepared for packing stripped cartilage were also removed at this time. The cartilage was placed on a plastic cutting board and cut into strips with a transverse section of 1 x 1 mm. Then these strips were packed and covered by fascia to form the grafts.The median follow-up was 23 months (range: 12 to 48 months). Twenty-two patients were satisfied with their augmented noses. Through examinations, biopsies, and MRIs, less resorption was observed with the Multi-stripped Autologous Cartilage Technique (MACT). Junctional step-offs, excessive prominence, and slanting grafts occurred in 3 patients; 2 of whom had revisions.Using multi-striped autologous cartilage grafts is an easier method to perform and could be another alternative technique for augmentative and reconstructive rhinoplasties.
