Alloplastic implants such as acellular dermal matrix (ADM) have been used for various aesthetic and reconstructive purposes since the 1990s. Rhinoplasty addresses both aesthetic and functional nasal impairments, often involving the adoption of grafting materials. Currently, autologous grafts, such as those using septal cartilage, are the gold standard. However, they pose the risk of donor site morbidity, technical challenges, and additional operative time. We review total complications, resorption/re-operation and success rates associated with the use of ADM in rhinoplasty. A literature search was conducted on PubMed, Prospero, DynaMed, DARE, EMBASE and COCHRANE databases. (Registry: CRD42023428019). A total of 462 patients from 15 studies were included, the mean (range) age was 30 (12-65) years, with a female-to-male ratio of 2:1. The most common indications for ADM were for cosmetic (35%, n = 163) and functional rhinoplasty (5%, n = 24). The most common type of ADM used was Alloderm (46%, n = 211). The most common indication for ADM was dorsal nasal augmentation (68%, n = 314). Eleven patients (2%) required revision surgery. The pooled success of ADM in rhinoplasty was 96% (95% CI 94 to 99, p = 0.93; I2 = 0%). 2% of patients developed postoperative complications and no statistically significant difference was seen in complications or success rates when comparing the different types of ADM. ADM in rhinoplasty was associated with fewer complications and re-operation rates, and similar if not less resorption compared to traditional autografts. Therefore, it can be a viable alternative to current autologous grafts in rhinoplasty surgery.
