Most of them presented hearing loss (8/12). In this study, 19 abnormal congenital patterns of the obturator foramen were observed. Ten of 19 patients presented audiometric anomalies. [em-consulte.com]

An approximately 2 mm space was present between the bony annulus and malleus ( Fig. 4 B), but a remnant of the malleus bar was present. [bjorl.org]

Most patients with CAA present with this moderate form. In minor cases, the ear canal is present but narrowed, and the middle ear is better developed. [emedicine.medscape.com]

Cole and Jahrsdoerfer reported these findings and noted that 50% of 54 stenotic ears with canals smaller than 4 mm developed canal cholesteatoma. [13] Clinicians should readily incorporate CT scanning into their diagnostic workup to ensure that no canal [emedicine.medscape.com]

While the stapes fixation has a good prognosis, the results in complex malformations may be unsatisfactory [59], [60]. [egms.de]

Outcome and Prognosis The goal of congenital aural atresia (CAA) surgery is to restore hearing to a speech-reception threshold (SRT) of less than or equal to 30 dB HL without the need for amplification. [microtiaexpert.com]

Etiology The etiology of microtia is often multifactorial. Only 15 % of patients have a positive family history. [entokey.com]

Etiology: 1. Exposure to teratogens like vitamin A 2. Vascular insults and genetic aberrations 3. Isolated microtia can occur with branchial arch anomalies 4. Can occur as a part of a single gene deletion or embryopathic development anamolies, eg. [drtbalu.co.in]

The hypothesis is that the abnormal position of the facial nerve prevents the stapes to make contact with the developing otic capsule at the site of the future oval window. Consequently, the development of the oval window is not induced. [radiologykey.com]
