Within the range of types, the ear canal may or may not be present and functional, and some to most of the features of the external ear are underdeveloped. If the ear canal is closed, conductive hearing loss is also present. [health.state.mn.us]

Anotia is the most severe (level IV) of the microtia ear deformity which presents as a small and often malformed outer ear. [earwells.com]

While similar triad of left facial paralysis, bilateral anotia, and cardiac disease, is presented by Pearl, the congenital deformity of external ears in the present case is more extensive. [4] The triad of anotia, facial paralysis, and congenital heart [indianjotol.org]

This contrasts with microtia, in which a small part of the pinna is present. Anotia and microtia may occur unilaterally (only one ear affected) or bilaterally (both ears affected). This deformity results in conductive hearing loss, deafness. [wikiwand.com]

The authors report a young infant who presented with failure to thrive and recurrent respiratory tract infections. The patient had bilaterally absent pinnae; instead small skin tags were present. [ncbi.nlm.nih.gov]

    When the patient cried vigorously, the was obviously paralysis of the right side with no contraction of the right side of the face, absence of the nasolabial fold and incomplete closure of the right eye confirming lower motor neuron lesion of the right [oatext.com]

Treatment

When anotia is an isolated condition, patients can typically lead normal lives after treatment. [earwells.com]

This may include a plastic surgeon for external ear reconstruction, an otolaryngologist for inner ear and hearing treatment, and a speech pathologist for speech treatment. Standard treatment for a missing ear is total ear reconstruction. [chop.edu]

[…] surgeon may suggest any number of possible treatment options. [chicagoinjurylawyer.net]

Evaluation & Treatment Microtia is characterized by an underdeveloped outer ear (pinna). It is usually unilateral, but may occur on both ears. [kidsplastsurg.com]

Treatment Treatment Options: No treatment is available for the overall condition but individual anomalies such as lid 'clefts' can be surgically repaired. Severe micrognathia may require tracheostomy at birth. [disorders.eyes.arizona.edu]

Prognosis

Prognosis of Anotia Prognosis of Anotia differs from one patient to another. Prognosis is good if the child is treated in his/her early childhood. [epainassist.com]

Prognosis for patients with anotia is generally very good when treated in early childhood. When anotia is an isolated condition, patients can typically lead normal lives after treatment. [earwells.com]

Traumatic facial palsy in neonates carries good prognosis as compared to developmental facial palsy that carries poor functional outcome. Conclusion CFP can be developmental or acquired. [ncbi.nlm.nih.gov]

Anotia Prognosis The outcome of the condition differs from one child to another. Treating the disorder during the early childhood of patients helps to get a better outcome. [hxbenefit.com]

Etiology

Additional study for factors associated with these characteristics could reveal clues for the etiology of these ear anomalies. [ncbi.nlm.nih.gov]

Our findings point to some potentially modifiable risk factors and provide further leads toward understanding the etiology of anotia/microtia. [jhu.pure.elsevier.com]

Etiology : Autosomal dominant inheritance in some cases [6]. Pathogenesis : unknown. [sonoworld.com]

The etiology of microtia and the cause of this wide variability in In this paper we review current knowledge of the epidemiology and genetics of microtia, In this paper, the term “microtia” includes anotia as the most severe. Microtia & Atresia. [letdowsrasac.tk]

Anotia Prevention In most cases, it is not possible to prevent the disorder due to its unknown etiology. However, avoiding the use of thalidomide during pregnancy can help lower the risk of having the condition for an unborn baby. [hxbenefit.com]

Epidemiology

Anotia and microtia are equally often associated with other malformations and show other similar epidemiological characteristics. [jmg.bmj.com]
