Summary: This study described three minor modifications to the sculpting of the auricle framework, which improved the appearance of the reconstructed auricle and laid a solid foundation for subsequent operations. Through a retrospective study of congenital microtia patients, it was found that these modifications resulted in a more satisfactory auricle appearance and improved patients' satisfaction.

Summary: This study investigates the use of cadaveric costal cartilage for ear reconstruction in microtia patients. The results demonstrate that cadaveric cartilage can serve as a viable alternative to autologous cartilage for primary microtia reconstruction, although infection and construct exposure remain potential risks. Further studies with longer follow-up and larger sample sizes are needed to assess long-term efficacy.

Summary: The surgical reconstruction of congenitally missing or malformed ears is challenging and involves complicated surgeries. It is easier to reproduce compromised ear features with a prosthesis. This article describes the prosthetic reconstruction of 3 patients who had received failed or suboptimal surgical reconstruction of their missing or deformed ears. Challenging characteristics included limited soft-tissue availability, skeletal hypoplasia with prominent concavity defect, and bilaterally missing ears with abnormally low hairline. Three-dimensional planning and stereolithography printing were used for ideal implant locations and mirror image reproduction.

Summary: The growing interest in auricular anatomy stems from two main areas of research: autologous ear reconstruction in medicine and human detection and recognition in surveillance and law enforcement. Systems for ear analysis vary based on the type of input data, acquisition tools, and algorithms used. While segmentation and recognition of the ear from the face is well-discussed, detection and recognition of individual anatomical elements remains an area that has not been extensively studied.

Summary: This study explores the author's experience with long-term follow-up analysis of secondary procedures in patients with unsatisfactory initial microtia reconstruction. The results suggest that using autogenous costal cartilage framework can achieve good aesthetic outcomes for patients undergoing secondary reconstruction surgeries.

Summary: The authors proposed a novel model of cartilage engineering involving co-culturing chondrocytes and adipose-derived stem cells on an allograft adipose-derived extracellular matrix scaffold. Results showed that cartilage induction was most prominent when cells were co-cultured on the scaffold at a specific ratio, demonstrating the potential of adipose-derived stem cells in supporting cartilage formation.

Summary: The study modified the conventional crescent cartilage block by sculpting a concavity at its posterior surface, which effectively improved the retroauricular contour and aesthetic outcomes for patients. The concave crescent-shaped block can enhance the auriculocephalic sulcus contour while ensuring ear projection.

Summary: In this study, we successfully isolated CD146+ pericytes from microtia remnant and investigated their chondrogenic potential using a poly(ethyl acrylate) (PEA) polymer to unfold fibronectin (FN). This material-based approach demonstrated similar chondrogenic potential to typical chondrogenic induction media while minimizing hypertrophy without the need for complex induction media formulations.

Summary: We developed a method to produce bone and cartilaginous structures using the self-regenerative capacity of the intercostal rib space. By placing anatomically precise 3D molds on the perichondro-periosteal or perichondral flap of the intercostal rib, we successfully obtained constructs for metacarpal head and auricle regeneration within 6 months. The regenerated tissues were used to repair a deformed metacarpophalangeal joint and perform auricle reconstructive surgery for microtia patients, showing good aesthetic and functional outcomes.

Summary: This study presented a novel method for ear reconstruction using the fully expansion technique without a skin graft. Results showed that the cartilage stack-up framework fabrication and fully expansion technique provided a well-defined, well-projected, and bilateral symmetrical reconstructed ear, with high patient satisfaction rate.

Summary: This study investigated the social perception of microtia and the impact of reconstruction on socially perceived attributes. The results showed that faces with microtia ears were perceived as less friendly, less healthy, and less successful compared to faces with normal ears, while there were no significant differences in socially perceived attributes between faces with normal ears and faces with reconstructed ears.
