BACKGROUND Microtia is a congenital defect characterized by disturbances in the size and form of the ear lobe. Anotia corresponds to the absence of the ear lobe. AIM To study the prevalence of microtia and anotia at the Maternity of the University of Chile Clinical Hospital. MATERIAL AND METHODS Analysis of the database of the Latin American Collaborative Study of Congenital Defects (ECLAMC...

Objective Prenatal ultrasound features, associated anomalies and genetic abnormalities of microtia cases were analyzed to explore the feasibility value prenatal for diagnosis microtia. Methods The ultrasonographic anomalies, chromosome examination results follow-up 81 fetuses with congenital retrospectively. Results Among diagnosed after birth, 2 missed on ultrasound, 1 case was as unilateral b...

Objectives: Microtia is the most commonly seen congenital ear defect, and involves an auricular deformity either unilaterally or bilaterally. The aim of this study was to fabricate silicone prostheses for a child with bilateral microtia using an innovative technique. Methods: This method involved the construction of bilateral ear prostheses using clips, which were located within the layers o...

BACKGROUND Autologous cartilage has been widely accepted as the frame material of ear reconstruction for patients with microtia. Although rare, there are multiple complications related with the surgical reconstruction techniques. The authors performed a systematic review of the English literature of microtia reconstruction to determine significant surgical factors that are predictors of postope...

OBJECTIVE To introduce our 2-stage reconstruction of microtia method, which results in a natural-looking contour of the reconstructed ears, one of the most demanding challenges in facial plastic surgery. METHODS In the first stage, the 3-dimensional cartilage framework is fabricated. The skin flap and retroauricular fascial flap are elevated in the mastoid area. Then the framework is wrapped ...

To determine the physiological functions of the mammalian double-stranded RNA-binding protein PACT, the single-copy mouse Pact gene was disrupted and expression of the protein was completely ablated. The most notable phenotypes of the Pact(-/-) mouse were reduced size and severe microtia. As a result of the congenital abnormality of both outer and middle ears, these mice were hearing impaired. ...

OBJECTIVES/HYPOTHESIS To identify the rate of hearing loss related to middle ear disease and the frequency of tympanostomy tube (TT) insertion in the contralateral ear of patients with unilateral microtia/aural atresia. STUDY DESIGN Retrospective case series of patients less than 3 years of age with unilateral microtia/aural atresia treated at an urban, tertiary care children's hospital from ...
