A staged auricular reconstruction in microtia patients was developed by using superficial mastoid fascia (as part of extrinsic postauricular fascia) to cover the cartilagenous framework due to its highly vascularized nature. Three branches of external carotid artery (superficial temporal artery, posterior auricular artery and occipital artery) were found to supply this fascia, this study was therefore aimed to investigate the dimension of blood supply from each vessel and also to demonstrate the existence of anastomoses among these arteries...

BACKGROUND: Autologous ear reconstruction for microtia is a complex, multi-stage procedure. The success of the procedure is dependant on how the patient perceives the outcomes of surgery and their overall experience. Patient reported measures are therefore crucial to developing the technique and improving the patient journey. AIM: The aim of this study was to use two reproducible patient reported outcome tools as an objective measure of microtia reconstructive surgery...

BACKGROUND: Advances in staged total auricular reconstruction have resulted in improved anterior auricular appearance; however, satisfactory postreconstruction esthetics of the retroauricular fold remain challenging. The postauricular appearance of the reconstructed ear depends largely upon optimizing the covering material. When used as the covering soft tissue for ear elevation, a flap containing primarily the upper portion of the retroauricular fascia has potential advantages over the conventional book cover-type retroauricular fascia flap...

Chromosome 11q13 deletion syndrome has been previously reported as either otodental syndrome or oculo-oto-dental syndrome. The otodental syndrome is characterized by dental abnormalities and high-frequency sensorineural hearing loss, and by ocular coloboma in some cases. The underlying genetic defect causing otodental syndrome is a hemizygous microdeletion involving the FGF3 gene on chromosome 11q13.3. Recently, a new form of severe deafness, microtia (small ear) and small teeth, without the appearance of eye abnormalities, was also reported...

BACKGROUND: In the two-stage procedures for the reconstruction of microtia, an axial flap of temporoparietal fascia (TPF) is widely used to cover the costal cartilage blocks placed behind the framework. Although a TPF flap is undoubtedly reliable, use of the flap has some morbidity and comes at the expense of the option for salvage surgery. METHODS: The authors devised a simplified procedure for covering the cartilage blocks by creating a pocket in the postauricular TPF...

Reconstructing congenital auricular defects due to hemifacial microsomia (HFM) is often required to deal with low hairline and defects of the temporal fascia/muscular systems. In this report, we present two cases of HFM patients (16-year-old and 20-year-old) with positional anomaly of the remnant lobule and 95% low hairline, who were treated with serratus anterior fascial flap (SFF) at the second stage of auricular construction. At the first stage, 3D costal cartilage framework was placed following the removal of hair-bearing skin, and was resurfaced with the pericranial flap...

Cyclophosphamide (CPA) remains one of the most widely prescribed anticancer drugs. It is also used in the treatment of rheumatoid arthritis, childhood nephrotic syndrome and systemic lupus erythematosus. It is a potent immunosuppressive agent. It is commonly used in blood and bone marrow transplantation. With the growing trend among women postponing childbearing, the number of women who are diagnosed with breast cancer is also increasing thus escalating the chances of exposure of the unborn child to antineoplastic drugs...

CONCLUSION: In conclusion, these result showed HADSCs could differentiate into chondrocytes-like cells, dependent on signaling induced by TGF-β3 and chondrocytes. This is a promising result and showed that HADSCs is a potential source for future microtia repair. The technique of co-culture is a positive way forward to assist the microtia tissue. OBJECTIVE: Reconstructive surgery for the repair of microtia still remains the greatest challenge among the surgeons...

Craniofacial malformations include a variety of anomalies, including cleft lip with or without cleft palate, craniosynostosis, microtia, and hemifacial microsomia. All of these anomalies can be either isolated or part of a defined genetic syndrome. A clinical geneticist or genetic counselor should be a member of the craniofacial team to help determine which patients have isolated anomalies and which are likely to have a syndrome. They would then arrange for the appropriate genetic testing to confirm the diagnosis of the specific syndrome...

Microtia is a genetic condition affecting the external ears and presents clinically along a wide spectrum: minimally affected ears are small with minor shape abnormalities; extremely affected ears lack all identifiable structures, with the most extreme being absence of the entire external ear. Multiple genetic causes have been linked to microtia in both animal models and humans, which are improving our understanding of the condition and may lead to the identification of a unified cause for the condition. Microtia is also a prominent feature of several genetic syndromes, the study of which has provided further insight into the possible causes and genetic mechanisms of the condition...

BACKGROUND: Craniofacial microsomia (CFM) is a congenital condition with wide phenotypic variability, including hypoplasia of the mandible and external ear. We assembled a cohort of children with facial features within the CFM spectrum and children without known craniofacial anomalies. We sought to develop a standardized approach to assess and describe the facial characteristics of the study cohort, using multiple sources of information gathered over the course of this longitudinal study and to create case subgroups with shared phenotypic features...

BACKGROUND: Microtia is a congenital deformity of the external ear that occurs in 1 of every 5000 births. Microtia reconstruction using traditional two-dimensional templates does not provide highly detailed ear shapes. Here, we describe the feasibility of using a three-dimensional (3D) ear model as a reference. MATERIALS AND METHODS: Seven children aged from 11 to 16 (6 grade III and 1 grade II microtia) were recruited from Seoul National University Children's Hospital, Korea...

Congenital facial palsy (CFP) is clinically defined as facial palsy of the seventh cranial nerve which is present at birth or shortly thereafter. It is generally considered to be either developmental or acquired in origin. Facial palsy of developmental origin is associated with other anomalies including those of pinna and external auditory canal, which range from mild defects to severe microtia and atresia. We report a 2-day-old male newborn that had right CFP with bilateral anotia and atresia of external auditory canals which is rare...

: Goldenhar syndrome is a rare condition which is characterized by a multitude of anomalies involving craniofacial structures, vertebrae, internal organs and usually occurs unilaterally. The etiology of this syndrome is unclear since it varies genetically and is linked to a plethora of reasons. Herein, we report a case of Goldenhar syndrome with hemifacial microsomia and microtia along with systemic involvement which was clinically and radio-graphically assessed. Many classical signs of the syndrome were present in the patient along with few rare ones...

CONCLUSION: Each of eight patients with bilateral microtia and atresia underwent bilateral reconstruction of the auricles and external auditory canals and were fitted bilateral canal-type hearing aids in the operated ears to replace a bone conduction hearing aid. The ability to discriminate inter-aural intensity difference (IID) and even inter-aural time difference (ITD) was retained in all these patients. OBJECTIVE: This study studied the post-operative sound lateralization ability of patients with bilateral microtia and atresia after total reconstruction of both auricles and external auditory canals, followed by fitting of bilateral canal-type hearing aids...

Infants with anotia and microtia (AM) often have other non-AM associated congenital anomalies. The purpose of this investigation was to assess the prevalence and the types of these associated anomalies in a defined population. The associated anomalies in infants with AM were collected in all livebirths, stillbirths and terminations of pregnancy during 29 years in 387,067 consecutive births in the area covered by our population-based registry of congenital malformations. Of the 146 cases with AM registered during this period, representing a prevalence of 3...
