The use of a local island flap, designed with retroauricular skin, is an excellent, simple, and reproducible innovation to the classic microtia ear reconstruction, allowing adequate coverage of the cartilage framework, specifically of the conchal area, sparing tense skin closure, reducing skin suffering and necrosis, with a better aesthetic result achieving the naturally depressed concha aspect. The flap design and surgical technique is described. This flap was used in 13 consecutive microtia ear reconstructions in our unit, no complications were encountered, and aesthetic results were excellent.

Microtia, along with trauma, represents one of the main causes of external ear malformation. Different clinical techniques were developed for the reconstruction of the auricle, but they all have some drawbacks. This work is focused on the development of an innovative 3D porous scaffold, printed by Fused Deposition Modelling (FDM) and based on laser-scanned images of the healthy contralateral ear of the patient.

Background: Postoperative infection is one of the main complications that affect the surgical effect of auricular reconstruction with tissue expansion. Understanding the susceptible time and distribution of pathogens is especially important for the treatment.
Method: The data of patients with infection after auricular reconstruction with tissue expansion from September 1, 2018 to August 30, 2024 were collected retrospectively.

Microtia is a congenital malformation characterized by underdevelopment of the external ear. While chondrocyte dysfunction has been implicated in microtia, the specific cellular abnormalities remain poorly understood. This study aimed to investigate mitochondrial dysfunction in microtia chondrocytes using single-cell RNA sequencing.

Microtia profoundly affects patients' appearance and psychological well-being. Tissue engineering ear cartilage scaffolds have emerged as the most promising solution for ear reconstruction. However, constructing tissue engineering ear cartilage scaffolds requires multiple passaging of chondrocytes, resulting in their dedifferentiation and loss of their special phenotypes and functions.

Objective: For full expansion of ear reconstruction, the stability of a cartilage framework is very important. However, most techniques for framework fabrication focus on three-dimensional structure and adequate projection. Few studies are available on improving the stability of the reconstructed framework.
