Malformations of the Auditory Ossicles


Presentation

  • This book presents the latest findings on reconstructive surgery performed jointly by plastic surgeons and otologists. Based on this concept, information on diagnosis, surgical procedures, outcomes, long-term results and psychology is discussed.[books.google.de]
  • 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]
  • A previous CT-examination, if present, can be a lot of help. The best one can do is to describe the extent of the previous operation, the state of the ossicular chain (if present), and the aeration of the postoperative cavity.[radiologyassistant.nl]
  • 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]
Physician
  • There are many physicians who do not have a desk computer or do not History feel at ease in using one.[books.google.de]
  • Learn how to stay ENT healthy, prevent problems, and manage existing conditions to improve your, or a loved one’s, daily life Find out more about the community of physician experts who can help you to Be ENT Smart and how the information was developed[entnet.org]
  • Suspicions of hearing loss should be brought to the attention of the primary care physician. A referral to an otolaryngologist (ear-nose-throat doctor) or audiologist (hearing specialist) may be needed.[chw.org]
  • Physicians should never discourage families from trying a bone conductor on their child with unilateral CAA, but families should not be discouraged if their child refuses to wear it.[emedicine.medscape.com]
  • The study was approved by the Ethics Committee of the Hamburg Chamber of Physicians (WF-70/16) and the methods were carried out in accordance with the approved guidelines.[nature.com]
Surgical Procedure
  • Based on this concept, information on diagnosis, surgical procedures, outcomes, long-term results and psychology is discussed.[books.google.de]
  • procedures, and postoperative hearing improvement.[ncbi.nlm.nih.gov]
  • In all the patients, prior to their qualification for the surgical procedure, a CT scan of the temporal bones was performed in order to exlude developmental anomalies of the inner ear.[czytelniamedyczna.pl]
  • Because of exposure to radiation should be avoided, there is no indication at all to perform a CT-scan in an infant, if a surgical procedure is planned years later.[egms.de]
Soft Tissue Mass
  • There is a soft tissue mass with erosion of the long process of the incus. This location is typical of a pars tensa cholesteatoma.[radiologyassistant.nl]
  • In “membranous atresia ”, the bony EAC is usually stenotic and a soft tissue mass is occupying the region where the tympanic membrane normally is located.[radiologykey.com]
Multiple Congenital Anomalies
  • Multiple congenital anomalies (A, B). Aplasia of the whole superstructure and thickening of posterior part of the footplate (A). Stapes hypoplasia, only the head and the proximal part of the crura is visible (B).[em-consulte.com]
Tinnitus
  • Learn More About Topic Tinnitus Over 50 million Americans have experienced tinnitus, or ringing in ears, which is the perception of sound without an external source being present.[entnet.org]
  • Tinnitus, a roaring in your ears, can be the result of loud noises, medicines or a variety of other causes. Meniere's disease may be the result of fluid problems in your inner ear; its symptoms include tinnitus and dizziness.[icdlist.com]
  • The cholesteatoma gradually expands, destroying the tissues of the middle ear, then those of the inner ear, and leading to chronic otitis, tinnitus, vertigo, and irreversible deafness.[ikonet.com]
  • Some examples of common diseases and conditions involving the ear include: swimmer's ear, ear wax cauliflower ear, Eustachian tube problems, otitis media (middle ear infection ), and tinnitus ( ringing in the ear ).[medicinenet.com]
  • It can also cause severe dizziness, lack of balance, tinnitus (ringing/buzzing sound in the ears), ear pain, and pressure. The disease can exist in mild or severe forms.[earq.com]

Hyperacusis
  • The mechanism of how paralysis of stapedius muscle, caused by an injury to the facial nerve, results in hyperacusis. 4. This model also suggests a possible reason why the pars lucida of the tympanic membrane exists.[ncbi.nlm.nih.gov]

Workup

  • 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]

Treatment

  • If the infection is due to bacteria, treatment is possible with antibiotics but if the infection is viral, antibiotics won’t work. Surgery is another treatment option, especially for children with ongoing infections.[earq.com]
  • A licensed medical professional should be consulted for diagnosis and treatment of any and all medical conditions. Call 911 for all medical emergencies.[umms.org]
  • In these cases always it is advisable to talk about technical devices as alternatives. 7.1.5 Postsurgical treatment The new meatus needs an intensive postoperative local treatment.[egms.de]

Prognosis

  • 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

  • Otosclerosis Otosclerosis anteriorly to the oval window (arrow) Otosclerosis is a genetically mediated metabolic bone disease of unknown etiology.[radiologyassistant.nl]
  • Etiology Factors that cause the developmental sequence of the ear canal and middle ear to cease in CAA are not known. Regions adjacent to the ear canal, including the jaw bone (mandible) may be affected as well.[emedicine.medscape.com]

Epidemiology

  • Epidemiology and genetics of microtia-anotia: A registry based study on over one million births. J Med Genet 1995;32:453-7. [ PUBMED ] 2. Weerda H. Classification of congenital deformities of the auricle. Fac Plast Surg 1988;5:385-8. [ PUBMED ] 3.[ijri.org]
  • Epidemiology Frequency The incidence of CAA is 1 in 10,000-20,000 live births. Unilateral CAA is more common than bilateral cases with an approximate ratio of 3-4:1.[emedicine.medscape.com]
Sex distribution
Age distribution

Pathophysiology

  • Recent studies have linked mutations in chromosome 18 to some patients with aural atresia. [6, 7] Pathophysiology Intimate knowledge of the anatomy and development of the ear is essential to understanding the clinical manifestations of CAA.[emedicine.medscape.com]
