Ear Deformity


Presentation

  • Abstract This case illustrates the variety of clinical presentations of Rosai-Dorfman disease. In this case, the disease presented as bilateral cauliflower ear deformity and was diagnosed on the basis of typical pathological findings.[ncbi.nlm.nih.gov]
School Problem
  • “Even if parents do not choose these options, or children refuse to wear them, teachers, parents and physicians should be vigilant about watching for signs of language delays and school problems and attempt to understand the root cause.”[source.wustl.edu]
Trismus
  • Trismus was also present. Contracture of the temporomandibular joint was suspected. The helices were flat, antihelices were minimal, and the ears protruded.[ncbi.nlm.nih.gov]

Workup

  • The workup for these patients consists of a hearing test, CT scan of the temporal bone to detect the exact course of facial nerve and delineation of the amount of middle ear and external canal deformity, and x-rays of the face and mandible to detect hemi-facial[nyee.edu]

Treatment

  • A simple and accurate surgical treatment is demonstrated by a cadaver dissection and a clinical case.[ncbi.nlm.nih.gov]
  • If the EarWell Infant Ear Correction System is an ideal option, our surgeon will develop a comprehensive treatment plan.[sbplasticsurgery.com]
  • Age of child Weeks of splint treatment required At birth 2 weeks 1 month of age 1 month 2 months of age 2 months 3 months of age 10 weeks 4-6 months at least 3 months Before Treatment After Treatment This is a revolutionary new technique that poses no[3fivetwo.com]
  • Here I outline the background and rationale for treatment of prominent ear deformity. I also highlight treatment options and review postoperative care and possible complications.[consultant360.com]

Etiology

  • The etiology of the deformities included burns (n 35), traffic accidents (n 10), cuts during fight (n 8), and human bite injuries (n 7).[ncbi.nlm.nih.gov]
  • Etiology : Autosomal dominant inheritance in some cases [6] . Pathogenesis : unknown.[sonoworld.com]
  • Etiology Most embryologic studies of the ear focus on the development of the 6 ear hillocks. These hillocks appear around the fundus of the first branchial groove by 38 days of gestation.[emedicine.medscape.com]
  • ETIOLOGY • Exposure to teratogens like vitamin A, thalidomide, isotretinoin • Vascular insults and genetic aberrations. • Isolated microtia can occur with branchial arch anomalies. • Syndromic associations of with congenital aural atresia include – Goldenhar[slideshare.net]

Epidemiology

  • Epidemiologic characteristics of anotia and microtia in California, 1989-1997. Birth Defects Research (Part A): Clinical and Molecular Teratology. 2004;70:472-475. National Birth Defects Prevention Network.[cdc.gov]
  • Epidemiology Frequency No statistics are available on the prevalence of protruding or prominent ears. Heredity plays a role in many deformities of the external ear.[emedicine.medscape.com]
  • EPIDEMIOLOGY • Microtia and congential auditory atresia occur in approximately 1 in every 6000 live births. • These deformities commonly occur unilaterally, more so on the right side. • Men are affected thrice as common as women.[slideshare.net]

Age distribution

Pathophysiology

  • Pathophysiology Features seen in the patient with prominent or protruding ears (in decreasing order of importance) include the following: Absent antihelical fold Obtuse scaphoconchal angle Increased distance of helical rim to scalp Deep conchal bowl Address[emedicine.medscape.com]

Prevention

  • The distally based perichondrio-adipo-dermal flap seems to prevent suture extrusion and may also help to reduce recurrence rates.[ncbi.nlm.nih.gov]
  • Many insurance companies offer coverage for this procedure, and it can ultimately prevent the need for plastic surgery in later years.[sbplasticsurgery.com]
