Objective: To evaluate long-term structural, functional, and cosmetic results as well as resorption with the use of irradiated homologous rib cartilage grafts (IHRGs).
Design: Cases in which IHRGs were used were reviewed for a long-term follow-up study for nasal and auricular reconstruction, dating back 18 years. A retrospective medical chart review was conducted in the cases in which the patients had returned for clinical examination with photographic documentation.
Results: A total of 118 patients who had undergone nasal reconstruction with a mean follow-up of 36 months were identified from our database. There were 12 patients who had undergone auricular reconstruction, with a mean follow-up of 82 months. Resorption with compromise in cosmesis was noted in 11% (11/102) of the grafts used in nasal reconstruction but in 71% (5/7) of those used in auricular reconstruction. Minor resorption without change in form or function was found in 29% (30/102) of the cases. Loss of support, which was related more to graft displacement rather than resorption, was identified in 19% (21/109) of the cases, and loss of support affecting cosmesis was observed in 8% (9/109) of the cases. Maintenance of form and function appeared to be unrelated to the amount of resorption noted for the nasal grafts but was significant for the auricular grafts (P < .01).
Conclusions: The longevity of IHRGs has been favorable for functional, structural, and cosmetic nasal reconstruction, with low levels of resorption identified clinically. The use of IHRGs was associated with an unacceptable rate of graft failure in auricular reconstruction; therefore, they are no longer selected for use in such cases.

Objective: This study aims to compare the postoperative thoracic deformity and scar aesthetic outcomes of auricular reconstruction between the conventional large-incision technique and small-incision technique with perichondrium preservation for costal cartilage harvesting.
Methods: A retrospective analysis was performed on 134 patients who underwent auricular reconstruction using tissue expanders and autologous costal cartilage harvested from the right chest wall between January 2021 and September 2023. Patients were divided into two groups according to the harvesting technique: the traditional large-incision group (n = 64) and the small-incision group with perichondrium preservation (n = 70).
Ear pinna growth and differentiation is conserved in murids and requires BMP signaling for chondrocyte proliferation.

Despite being a major target of reconstructive surgery, development of the ear pinna remains poorly studied. Here we provide a cellular characterization of late gestational and postnatal ear pinna development in two rodents and investigate the role of BMP5 in expansion and differentiation of auricular elastic cartilage. We find that ear pinna development is largely conserved between Mus musculus and the highly regenerative Acomys dimidiatus.

CAAs are congenital malformations of the auricle ranging from ear underdevelopment to anotia, lacks standardized classification, impacting our outcome of different reconstruction approaches. This scoping review aimed to explore which CAA classifications are most used in current ear reconstruction practices. We conducted a scoping review following the PRISMA guidelines, searching MEDLINE and Embase databases on November 1st, 2023.

Cases of microtia combined with pulmonary hypoplasia are occasionally in clinics, and its genetic etiology has so far proved inconclusive. Here, aiming to contribute to a better understanding of microtia-related comorbid respiratory anomalies, the authors provide a clinical and genetic description of a rare trio family of which the son suffers combined deformities of right microtia, left pulmonary hypoplasia, and dextrocardia using whole-genome sequence (WGS). A novel potential pathologic compound heterozygosity in the FREM1 gene was identified and validated by the trio and bioinformatics analysis.
