Abstract
BACKGROUND Accessory auricle is a common congenital abnormal auricular appendage with various forms of presentation. The authors proposed a practical classification system based on the involved anatomical subunits (tragus, the anterior notch and the intertragal notch) and described the corresponding surgical procedures. METHODS The authors reviewed and analyzed 80 patients (96 ears) who underwent accessory auricle excisions form January 2018 to December 2021. Accessory auricles were classified into three categories: simple (no deformed subunits), complex (several deformed subunits) and compound (coexistence of simple and complex type). The complex type was subclassified into notch and tragal subtypes. The tragal subtype was subclassified into subtype A, B and C, according to the location, contour and size of the involved tragus. Surgical methods were described, and postoperative outcomes were assessed. RESULTS Simple type was the most common type (54%) and compound type was less common (15%). In addition, there were 28 (29%) tragal subtype accessory auricles and 2 (2%) notch subtype. Among the tragal subtype, A was the most commonly observed (25%), followed by B (2%) and C (2%). Patients were followed for an average of 11.3 months. One patient experienced delayed wound healing and 6 patients showed hypertrophic scars. The average aesthetic score, evaluated by a 4-point Likert scale (1 = poor, 2 = fair, 3 = good, 4 = excellent), was 3.67 ± 0.06 points. The OSAS and PSAS scores were 9.29 ± 0.44 and 10.84 ± 0.40, respectively. CONCLUSIONS The innovative classification system of accessory auricles can reflect whether there was a combined deformity and the deformed subunits, and guide decisions on surgical approaches.

Abstract
Background Microtia is an uncommon congenital malformation ranging from mild anatomic structural abnormalities to partial or complete absence of the ear leading to hearing impairment. Congenital microtia may present as a single malformation (isolated microtia) or sometimes associated with other congenital anomalies involving various organs. Microtia has been classified in three degrees according to the complexity of the auricular malformation and to anotia referred to the total absence of the ear. Genetic role in causing auricular malformation has been widely demonstrated, and genotype-phenotype correlation has been reported in cases of syndromic microtia. Case Presentation We report here a young patient with a third degree of scale classification and aural atresia. The patient showed unspecific facial dysmorphism, speech delay, precocious teething, hair white patch, and stereotypic anomalous movements. Genetic analysis displayed a de novo 16p13.11 deletion. Conclusion Microtia with aural atresia is an uncommon and severe birth defect, which affects functional and esthetic aspects, often associated with other malformations. As traumatic this disorder may be for the parents, the microtia and aural atresia are treatable, thanks to the improving and evolving surgical techniques. Based on the genetic analysis and the clinical features observed in the present case, a genotype-phenotype correlation has been proposed.

Abstract
Auricular fistula is a common congenital auricular malformation, characterized as a small opening in the skin and a subcutaneous cyst. It can be classified in different ways according to positions of pits and directions of fistula tracts. The term preauricular fistula and variant type of preauricular fistula (postauricular fistula) are used. Auricular fistula prevalence varies in countries and populations, and its actual prevalence is presently unknown. The most accepted and widely cited theory of auricular fistula etiopathogenesis is an incorrect or incomplete fusion of six auricular hillocks that are mesenchymal proliferations. Auricular fistula can occur either sporadically or genetically. The pattern in inherited cases is thought to be incomplete autosomal dominant, with variable expressions, reduced penetrance, and inapparent gender differences. Auricular fistula has several forms and is reported as being a component of many syndromes. In the field of genetics, currently, there is no related review to comprehensively summarize the genetic basis of auricular fistula and related disorders. This article provides a comprehensive review of auricular fistula, especially congenital preauricular fistula, which accounts for the majority of auricular fistula, by summarizing the clinical manifestations, histological and embryological development, genetics, examinations, and treatments, as well as syndromes with auricular fistula.

Abstract
OBJECTIVES Microtia is a congenital anomaly of the outer ear. Although genetic and environmental factors could play a role, no consensus has been established on the pathogenesis and cause of this condition. In this study, we surveyed the frequency and pattern of family history in patients with microtia in a Chinese specialty clinic population. METHODS We evaluated data from 672 patients (mean age = 9.2, male-to-female ratio = 2.6:1) with microtia admitted to the Department of Auricular Reconstruction at the Plastic Surgery Hospital of Peking Union Medical College from December 2014 to February 2016. Family history of congenital ear anomalies across three generations was recorded. Pearson chi-square test or Fisher exact test was used to test the associations between the characteristics of microtia and hereditary features. RESULTS A family history of auricle anomalies was identified in 202 patients (30.1%), of whom, 95 families showed vertical transmission, 14 families skipped a generation, and 120 families showed family aggregations. The incidence of family history varied with grades of microtia (P = 0.001). Patients with preauricular tags or pits (38.3%) had a higher familial incidence of microtia than those with simple microtia (24.1%) (P < 0.001). CONCLUSION Patients with a lower grade of microtia demonstrated a higher incidence of family history. Patients with microtia had significantly more relatives with preauricular tags or pits. Microtia and preauricular tags or pits are different manifestations of the same defect, and their significant concurrency among relatives suggests that a considerable proportion of microtia is inherited and could recur with varying degrees of severity in other family members.

Abstract
Organisms may retain nonfunctional anatomical features as a consequence of evolutionary natural selection. Resultant atavistic and vestigial anatomical structures have long been a source of perplexity. Atavism is when an ancestral trait reappears after loss through an evolutionary change in previous generations, whereas vestigial structures are remnants that are largely or entirely functionless relative to their original roles. While physicians are cognizant of their existence, atavistic and vestigial structures are rarely emphasized in anatomical curricula and can, therefore, be puzzling when discovered incidentally. In addition, the literature is replete with examples of the terms atavistic and vestigial being used interchangeably without careful distinction between them. We provide an overview of important atavistic and vestigial structures in the head, neck, and spine that can serve as a reference for anatomists and clinical neuroscientists. We review the literature on atavistic and vestigial anatomical structures of the head, neck, and spine that may be encountered in clinical practice. We define atavistic and vestigial structures and employ these definitions consistently when classifying anatomical structures. Pertinent anatomical structures are numerous and include human tails, plica semilunaris, the vomeronasal organ, levator claviculae, and external ear muscles, to name a few. Atavistic and vestigial structures are found throughout the head, neck, and spine. Some, such as human tails and branchial cysts may be clinically symptomatic. Literature reports indicate that their prevalence varies across populations. Knowledge of atavistic and vestigial anatomical structures can inform diagnoses, prevent misrecognition of variation for pathology, and guide clinical interventions.

Abstract
Morphologically stable scaffold-free elastic cartilage tissue is crucial for treating external ear abnormalities. However, establishing adequate mechanical strength is challenging, owing to the difficulty of achieving chondrogenic differentiation in vitro; thus, cartilage reconstruction is a complex task. Auricular perichondrial chondroprogenitor cells exhibit high proliferation potential and can be obtained with minimal invasion. Therefore, these cells are an ideal resource for elastic cartilage reconstruction. In this study, we aimed to develop a novel in vitro scaffold-free method for elastic cartilage reconstruction, using human auricular perichondrial chondroprogenitor cells. Inducing chondrogenesis by using microscopic spheroids similar to auricular hillocks significantly increased the chondrogenic potential. The size and elasticity of the tissue were maintained after craniofacial transplantation in immunodeficient mice, suggesting that the reconstructed tissue was morphologically stable. Our novel tissue reconstruction method may facilitate the development of future treatments for external ear abnormalities.

Abstract
The external ear (EE) is an osseous-cartilaginous structure that extends from the auricle to the tympanic membrane. It is divided into two parts: the auricle (or pinna) and the external auditory canal (EAC). Given the ease of access to the EE, imaging studies are not always needed to make a diagnosis. However, when lesions block visual access to areas deep to the EE abnormality, complications are suspected, or there is lack of response to treatment, imaging becomes essential. A basic understanding of the embryologic development and knowledge of the anatomy of the auricle and EAC are useful for accurate diagnosis of EE lesions. Congenital, traumatic, inflammatory, neoplastic, and vascular conditions can affect the EE. An overview of the anatomy and embryologic development of the EE is presented, with discussion and illustrations of common and uncommon conditions that affect EE structures and a focus on the CT and MRI features that are of interest to radiologists. CT is usually the first diagnostic modality used to evaluate the EAC and is the superior method for demonstrating bone changes. MRI provides excellent tissue characterization and enables one to better define lesion extension and perineural tumor spread. In addition, a flowchart to facilitate the differential diagnosis of EE abnormalities is provided. Online supplemental material is available for this article. ©RSNA, 2022.
