Since the pioneering use of autologous costal cartilage for microtia reconstruction, significant progress has been made in treating microtia, effectively improving patients' quality of life and reducing their psychological burden. Cartilage auricle reconstruction is the primary treatment, but many postoperative complications can occur. Common postoperative complications include infection and hematoma at the recipient site, pleural tears at the donor site, and thoracic scoliosis. Among these, severe postoperative pneumonia is a rare but potentially fatal complication. This study presents a case of severe pneumonia after auricular reconstruction with autologous cartilage. It details the complications associated with autologous cartilage microtia reconstruction, especially pulmonary complications, and suggests a possible relationship between pulmonary complications and auricular reconstruction using cartilage.

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.

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.

Objective: Autologous rib harvest with manual framework production is the current gold standard for microtia reconstruction. Recent clinical success with implantation of cadaveric costal cartilage grafts opens the possibility of point of care auricular framework production. This paper assesses the feasibility and efficiency of 3D milling of cadaveric costal cartilage for auricular framework production.
