The Auricular Perichondrium Sleeve (APS) for Nasal Dorsum Refinement.

[BACKGROUND] During rhinoplasty, there is often a need to perform camouflage and esthetic augmentation of the nasal dorsum. Some of the most well-studied methods include the use of deep temporal fascia and diced cartilage in fascia. Due to less trauma, taking the rectus abdominis fascia in combination with rib harvesting is becoming widespread. However, in cases where only camouflage or augmentation of the nasal dorsum is required, it is possible to avoid taking the rib and the mentioned fascia, using auricular materials successfully through a single incision.

[OBJECTIVES] The article described the using of auricular perichondral sleeve for camouflage and dorsal augmentation in empty condition and filled with auricular cartilage in the modeling of diced cartilage auricular perichondral sleeve grafts.

[METHODS] For camouflage and augmentation of the nasal dorsum for primary, post-traumatic and secondary cases of rhinoplasty through open and closed approaches, auricular perichondrium was used in three conditions (1) empty auricular perichondral sleeve, (2) full-length filled with diced auricular cartilage, and (3) partially filled sleeve. The techniques of application of these grafts were described depends on the clinic situation.

[RESULTS] The authors report their experience with 122 clinical cases from February 2019 to March 2022. The patients were divided into three groups depending on the types of grafts that were used.

[CONCLUSION] Autologous auricular perichondrium can be used for camouflage and dorsum augmentation for primary, post-traumatic, and secondary cases.
