Background: Minor physical anomalies (MPAs) are subtle anatomical deviations in one's appearance and may suggest altered embryogenesis. MPAs have been shown to be more common in neurodevelopmental disorders (NDDs) compared with typical development. Still, further studies are needed on MPAs in NDDs, especially using twins to adjust for confounding familial factors. Methods: Clinical assessments were conducted on 116 twins (61 NDD, 55 controls) from 51 monozygotic and 7 dizygotic pairs to examine MPAs and their association with DSM-5 defined NDDs...

The progress made in the development of the silicones and percutaneous titanium implants allow for rehabilitation of patients with microtia with an inconspicuous auricular prosthesis. The art of making the prosthesis by the dedicated anaplastologist is the key for the success of this approach. Most patients with microtia desire camouflage. The greatest advantage of the auricular prosthesis is that it can be manufactured as a mirrored replica of the opposite side. The outcome is predictable. Computer science with virtual planning and rapid prototyping is about to revolutionize the process of prosthetic auricular rehabilitation...

Patients with microtia and congenital aural atresia should have a comprehensive hearing assessment early in life. Options for hearing habilitation should be presented, and children with bilateral aural atresia should be fitted with a bone conducting hearing device to support normal speech and language development. If atresia surgery is pursued, the microtia surgeon must be aware of certain principles. This article presents recommendations on options for potentially improving hearing in children with congenital aural atresia: assessing surgical candidacy; chronology and timing of surgeries; functional importance of certain ear structures; and understanding the possible locations of an aberrant facial nerve to avoid injury in these patients...

Alloplast-based ear reconstruction has become more popular over the years because it offers many advantages compared with the traditional staged autologous costal cartilage approach. Advantages include earlier reconstruction in the setting of microtia, fewer procedures, less donor site morbidity, shorter surgeon learning curve, and improved consistency in the final aesthetic result. Although other implantable materials have been used in auricular reconstruction with variable success, porous high-density polyethylene frameworks combined with recent advances in the creation of the soft tissue coverage have significantly improved outcomes with minimal complications and long-term viability...

Reconstruction of the microtic ear is one of the most challenging, yet gratifying surgical experiences. Careful planning, attention to detail, and conservative tissue management are necessary for excellent results. Technologies continue to evolve; with the advancement of cartilage tissue engineering, the future of ear reconstruction is very promising.

REVIEW
Akira Yamada
Nagata technique becomes most popular method of autologous rib microtia construction. To achieve successful outcome, 3 keys must be perfect: skin envelope, 3D cartilage framework, and proper location of the construct. The first step of the surgery is to identify "auricular rectangle." Relationship between the auricular rectangle and the vestige will determine if the vestige is usable for surgery. Rib cartilage must be harvested without perichondrium to prevent chest deformity. Lobule split technique is the hallmark of the Nagata technique, which allows skin envelope expansion, and allows deeper conchal cavity...

Total ear reconstruction for microtia is usually accomplished in 2 stages which is known as Nagata technique. After framework fabrication and implantation, the elevation procedure is required as a second step surgery. The authors are introducing a novel material for augmenting projection of rib cartilage framework in microtia treatment.

OBJECTIVE: To investigate the characteristics of stenotic external auditory canal (EAC) (e.g., shape, length, orientation, and curvature) and to compare them with those of the cholesteatoma and no cholesteatoma groups, which may help to explain cholesteatoma formation to a certain degree. METHODS: Computed tomography scans of two groups of patients (with and without EAC cholesteatoma) were analyzed. We determined the degree of microtia, the stenosis of EAC, radius and curvature of osseous EAC bending (abbreviated as OEB-r and OEB-c, respectively), and other anatomic parameters of EAC by using Mimics and Matlab...

BACKGROUND: Mechanical properties of tissue-engineered cartilage and a variety of endogenous cartilage were measured. The main goal was to evaluate if the tissue-engineered cartilage have similar mechanical characteristics to be replaced with rib cartilage in microtia reconstruction. Such study lays the foundation for future human clinical trials for microtia reconstruction. METHOD: Atomic force microscopy and compression testing were used to measure the viscoelasticity of tissue-engineered cartilage (stem cell seeded on Poly lactic co-glycolytic acid nanofibers and Pellet) and endogenous cartilage: conchal bowl, microtic ears, preauricular remnants, and rib...

Microtia is a congenital malformation of the external ear caused by genetic and/or environmental factors. However, no causal genetic mutations have been identified in isolated microtia patients. In this study, we utilized targeted genomic capturing combined with next-generation sequencing to screen for mutations in 307 deafness genes in 32 microtia patients. Forty-two rare heterozygous mutations in 25 genes, including 22 novel mutations in 24 isolated unilateral microtia cases were identified. Pathway analysis found five pathways especially focal adhesion pathway and ECM-receptor interaction pathway were significantly associated with microtia...
