Craniomaxillofacial congenital anomalies comprise approximately one third of all congenital birth defects and include deformities such as alveolar clefts, craniosynostosis, and microtia. Current surgical treatments commonly require the use of autogenous graft material which are difficult to shape, limited in supply, associated with donor site morbidity and cannot grow with a maturing skeleton. Our group has demonstrated that 3D printed bio-ceramic scaffolds can generate vascularized bone within large, critical-sized defects (defects too large to heal spontaneously) of the craniomaxillofacial skeleton...

Although facial paralysis is a fundamental feature of hemifacial microsomia, the frequency and distribution of nerve abnormalities in patients with hemifacial microsomia remain unclear. In this study, the authors classified 1125 cases with microtia (including 339 patients with hemifacial microsomia and 786 with isolated microtia) according to Orbital Distortion Mandibular Hypoplasia Ear Anomaly Nerve Involvement Soft Tissue Dependency (OMENS) scheme. Then, the authors performed an independent analysis to describe the distribution feature of nerve abnormalities and reveal the possible relationships between facial paralysis and the other 4 fundamental features in the OMENS system...

BACKGROUND Mycophenolate mofetil (MMF) is one of the most commonly prescribed drugs to prevent organ transplant rejection in combination with calcineurin inhibitors and steroids. It has a different toxicity profile than tacrolimus and cyclosporine.  Gastrointestinal tract disturbances are the most common adverse effects. The use of MMF in pregnant women, however, holds great risk of miscarriage and fetal development defects such as external ear malformation, ocular anomalies, cleft lip and palate, and abnormality of distal limbs, heart, esophagus, and kidneys...

The objective of the present study was to develop and introduce into the clinical practice the method for the combined aesthetic and functional rehabilitation of the patients presenting with congenital atresia of the external auditory canal (CAEAC) and the concomitant microtia. A total of 8 patients at the age from 6 to 21 years with unilateral CAEAC and microtia were given the surgical treatment. During the intervention, atresia was resolved using the trans-mastoid approach, tympanoplasty of autofasciae and ossiculoplasty making use of the partial titanium prosthesis and the placement of cranial osteointegratable titanium implants...

AIM: The aim of this study is to present the middle fossa technique (MFT) as an alternative for patients who cannot undergo traditional surgery for active transcutaneous bone conduction implants (ATBCI) due to their altered anatomy or desire for future aesthetic reconstruction. DESIGN: A case series descriptive study was designed. The MFT was developed. Preoperative and postoperative information from 24 patients with external auditory canal atresia (EACA) and implanted with ATBCI was reviewed...

BACKGROUND: Auricular reconstruction is one of the most challenging procedures in the field of plastic surgery. The aims of this study were to apply the modified 2-stage method to perform auricular reconstruction and to summarize the clinical experience in the past 10 years. METHODS: Auricular reconstruction was performed in 243 patients (total 254 ears) of congenital microtia using autologous costal cartilage. The whole procedure is divided into 2 stages. Stage I: the individualized framework fabricated with autologous costal cartilage is inserted into subcutaneous pocket in the mastoid region, and then the earlobe was transposed backward to connect with the lower part of the framework...

Formation of an ideally-shaped tragus remains one of the most challenging issues during staged tragus reconstruction in microtia patients. The authors describe a new method used to treat a unique case of concha-type microtia in which the 10-year-old male patient had only a portion of pre-existing cartilage at the tragus site. An anomalous skin lump was also present. During the initial stages of the reconstruction, the two-stage Nagata method was used for surgical correction of the microtia. An autologous rib cartilage graft was used to form the ear framework...

BACKGROUND: Nagata's two-stage technique for microtia reconstruction using autologous costal cartilage consists of the implantation of a fabricated cartilage framework and the elevation of the constructed auricle. Achieving long-lasting, sufficient projection of the auricle is a goal of second-stage surgery; however, unfavorable outcomes have been seen in some patients, with suboptimal long-term elevation. The present study aimed to investigate prognostic factors that might contribute to adverse outcomes following the ear elevation operation...

INTRODUCTION: Congenital Aural Atresia (CAA) or microtia is a malformation that results in esthetic and functional problems. There is little information on prevalence, considering that Latin American is the most affected region in the world. OBJECTIVE: To determine the prevalence of microtia, considering the different ethnical structure of the population. METHODS: A retrospective analysis was performed of the clinical reports of newborn infants (public hospitals) in three different regions...

PURPOSE: With the aim of implementing good projection of the three-dimensional frame (auriculo-cephalic angle) and maintaining projection, a significant issue during the stage of auricular elevation for avoiding the potential for dislodging the cartilage blocks remains. Herein we present an innovative and technically simple method of transcutaneous fixation of the costal cartilage block during the stage of auricular elevation. MATERIALS AND METHODS: After elevation of ear frame from the basement, two suspension stitches on the surface of the elevated ear were used to fix the embedding cartilage block into the auriculo-cephalic sulcus at the upper (bifurcation point of the anti-helix where the inferior and superior crus meet to form the triangular fossa) and lower (projection point of the concha wall, parallel to the level of the tragus) ones...

Auricular reconstruction is an interdisciplinary approach where multiple specialties play a vital role in the treatment provided to the patient. This article provides a comprehensive interpretation of the process carried out for the fabrication of a custom-made prosthetic conformer for the management of postoperative contraction of a skin graft after ear reconstruction surgery-Brent stage III. The prosthesis is used as a precautionary measure and is simple, effective, and economical.

INTRODUCTION: To compare the audiological results of Bone Conduction Hearing Aid (BCHA) on hard test band and Bonebridge (BB) implant among children with microtia and atresia. METHODS: This is a retrospective review of patients with microtia and atresia who underwent BB implant insertion from September 2014 to February 2017 in Starship Children's Hospital. Preoperative audiological testing using a powered BCHA (Oticon Medical Ponto Pro Power) on a hard test band was used to compare post-operative hearing assessments with the BB...

OBJECTIVES/HYPOTHESIS: This study compares the hospital cost of osseointegrated implants for retention of an auricular prosthesis to autologous ear reconstruction. STUDY DESIGN: Retrospective review. METHODS: This study includes patients who underwent reconstruction for either congenital or acquired ear defects at Duke University Medical Center during 2009 to 2015. RESULTS: A total of nine patients had autologous repair representing nine operative ears, and 16 patients had an osseointegrated implant representing 18 operative ears (two bilateral)...

OBJECTIVES: The retroauricular fascia flap (RFF) is one of the most commonly used vascularized linings for auriculocephalic sulcus reconstruction in staged total auricular reconstruction. This study aims to investigate the histomorphometric features regarding the retroauricular fascia.

OBJECTIVE AND IMPORTANCE: Reports of patients with concurrent middle and inner ear anomalies are rare. These patients present a surgical challenge for cochlear implantation. The surgical risk must be weighed against the predicted benefit of the patient's hearing outcome and subsequent development of speech and language as well as their quality of life.

OBJECTIVES: The aim of our study was to investigate subjective information concerning parental experiences and preferences with regard to the initial information that is provided right after the birth of a child with microtia. The analysis of these data is intended to help professionals improve the way in which such conversations are conducted. As a result, future parents may feel better informed and, hence, better fit to cope with challenges they may encounter having a child with microtia...
